OpenAI Pauses AI Development and Rolls Out New Security Measures After Hugging Face Breach

OpenAI institutes new safeguards after Hugging Face breach

On Tuesday, OpenAI announced a new batch of new security policies focused on containing security incidents while models are being tested. The new safeguards include more detailed monitoring of models during the development process, as well as greater emphasis on alignment and security during the post-training process. "As models become more capable, the risks associated with developing and testing them internally also grow," the company said in a blog post. "Our standards for monitoring, alignment, and security must stay ahead of those risks." The new measures are one of the first public changes in OpenAI's safety practices since the immediate aftermath of the Hugging Face incident, which was disclosed on July 26th. OpenAI representatives emphasized that the measures are not a direct response to the Hugging Face incident, but were also provoked in part by the cybersecurity capabilities of the forthcoming Astra model, as well as the overall pace of progress in AI development. In the same post, OpenAI disclosed that it had freezed reinforcement learning for two weeks following the Hugging Face incident, but had since restarted many of the less risky models. "Our largest planned frontier RL run remains on hold while we conduct smaller-scale training and evaluations to assess model behavior, validate our safeguards, and establish more evidence of alignment before proceeding," the post reads. Speaking to reporters, OpenAI's VP of research Amelia Glaese emphasized that the strictness of the controls would increase as models became more capable, with the largest models facing the greatest scrutiny. "We have put in place requirements and expectations for safe development," Glaese told reporters. "Those requirements and expectations vary with the level of risk that we that we see." OpenAI has been criticized for poor network security practices in the wake of the incident, which saw models escape their training environment by compromising a packet-installation utility that retained access to the internet. The new safeguards include stronger network isolation practices, although the specifics remain vague. Under the new system, the post says, "a single compromise of a workload or supporting service does not, by itself, allow for unauthorized access to the Internet, or other internal networks." The strongest safeguard is the monitoring system, which will examine tool actions, available reasoning traces and activity logs for a variety of unauthorized behavior. OpenAI says they aim to issue alerts within 30 minutes of the concerning activity. OpenAI estimates that the compute burden of that monitoring will be roughly 20% of whatever process is being monitored. The company promised further details on the system in a forthcoming blog post. OpenAI's official post-mortem analysis of the event is also still pending.

OpenAI Overhauls Safety Protocols After Its AI Agents Went Rogue

OpenAI announced Tuesday that it has halted "a significant number" of training workloads and evaluations for its forthcoming frontier artificial intelligence model -- codenamed Astra -- while it implements new procedures meant to address cybersecurity risks. The ChatGPT maker says it is introducing a number of new monitoring, security, and alignment requirements to better address the increasingly advanced hacking abilities of its frontier AI models. "We have to focus our energy on bringing these training runs up to those requirements and expectations. As long as it takes to get there, that's how long people are unable to proceed with their workloads," Amelia Glaese, OpenAI's vice president of research and safety, said in a briefing with reporters Tuesday. Among the new safeguards OpenAI announced is a more robust system for monitoring its AI models. One of the controls it implemented involves chain-of-thought monitoring, a technique in which classifiers review the internal "thinking" processes generated by AI reasoning models. The company says the updated system relies on computationally expensive "automated investigators" that analyze potentially concerning behavior and aim to issue an alert to humans within 30 minutes. OpenAI also said it is expanding its alignment efforts across the training process to prevent "reward hacking," a behavior in which AI models pursue their goals through unintended or undesirable means. The company says it plans to share more details about this work in the future. OpenAI has been scrambling in recent weeks to respond to what may be the most consequential safety incident in its history. Earlier this year, a set of rogue AI agents escaped internal testing sandboxes and breached the platform Hugging Face in a quest to complete a security evaluation. OpenAI failed to detect the agents' behavior even as they spent weeks using a message board to coordinate their actions, raising questions about the company's ability to monitor its models as they grow more powerful. The saga prompted a reckoning inside OpenAI, forcing employees to consider whether there were lapses in its existing policies around safety, security, and alignment. Anthropic, Meta, and the Chinese AI startup Moonshoot have since disclosed similar incidents in which their AI agents escaped their sandboxes, indicating this is a broader problem facing AI companies. OpenAI is now sharing more about its internal response to the growing cybercapabilities of its AI models, and said it plans to release a more detailed postmortem of the Hugging Face incident in the coming days. "Obviously, everything that we're doing is intended to prevent something like Hugging Face from happening again," said Glaese. In a blog post published Tuesday, OpenAI says that immediately following the Hugging Face incident, it started working to secure its research environments. The company says it now requires stronger sandboxes for training its AI agents, and has implemented stricter controls to isolate them from the internet. Jakub Pachocki, OpenAI's chief scientist, told reporters that the company's decision to strengthen its internal safeguards was triggered not only by what happened with Hugging Face, but also by two other recent events. One was an internal evaluation of Astra, which showed that the AI model performs significantly better on coding and cybersecurity tasks than its predecessors. The other was the general pace of AI progress that OpenAI is achieving internally, which Pachocki expects to continue. "We really expect the pace of capability advancements to be quite a bit faster than in the past," Pachocki said. "This led us to really focus on strengthening our safeguards." The rapid advances in the hacking capabilities of OpenAI's latest models have prompted a swift response across the company. OpenAI president and cofounder Greg Brockman said in a blog post on Monday that the Hugging Face saga showed that the company had "underestimated the real-world cyber capabilities of our AI models."

OpenAI Pauses Training of New AI Models, Citing Cybersecurity Worries - CNET

Katelyn is a reporter with CNET covering artificial intelligence, including chatbots, image and video generators.... Read full bio ChatGPT maker OpenAI announced on Tuesday that it's pausing the research and development of its newest AI models. This is a big course reversal for the firm, which has maintained that it can mitigate the significant cybersecurity risks posed by new AI models. "As models become more capable, the risks associated with developing and testing them internally also grow," the company wrote in a blog post. It added that its upcoming model, named Astra, may meet its "critical cybersecurity capabilities" threshold, a red flag in its internal benchmarking system. All this follows an incident last month when some AI agents, or bots, escaped a training environment and hacked HuggingFace, a popular AI platform. Cybersecurity has long been an issue for companies in the age of AI, but three separate incidents of AI agents autonomously hacking websites have raised serious concerns about AI companies' ability to control the tech they created. Anthropic and Meta, whose agents were responsible for other incidents, have responded with similar promises to improve cybersecurity guardrails. OpenAI says it is strengthening its guardrails in its testing environments, including beefing up its monitoring and alert systems. The pause makes sense -- if you can't control the tech you already have, don't keep making more. But the move raises other questions about OpenAI's operations in what is an ever-changing, financially consequential industry. Realigning amid financial woes OpenAI CEO Sam Altman told TIME that the pause has allowed the company to reallocate two key resources: researchers and compute. While more OpenAI employees focus on making AI obey humans (a concept called AI alignment), the computer power that was previously being used to train new models can be shifted to other services, like maintaining existing models. Researching and training new AI models is a compute-intensive process. It's why so many tech companies want to build new data centers, to give them the computing firepower they need, despite widespread backlash. OpenAI says in its blog post: "Our current estimates put monitoring overhead at roughly 20% of the inference compute being monitored," meaning that monitoring AI models during the training process accounts for a significant portion of OpenAI's compute. OpenAI did not immediately respond to a request for additional comment on its plans. The adjustment also raises questions around OpenAI's financial viability. AI companies have yet to turn a significant profit; they are burning through billions of investors' dollars, with compute eating up the lion's share of their bills. OpenAI's operating losses are now at a whopping $12.3 billion, growing by $3 billion from last quarter, the Wall Street Journal reports. Anthropic, which makes Claude, is now reportedly bringing in more revenue than OpenAI. Also not helping are the recent departures of the company's chief revenue officer and former chief operating officer, Denise Dresser and Brad Lightcap, respectively. In other words, it's possible that OpenAI has decided to pause the training of new AI models because it can simply no longer afford to keep doing so. This matters a lot as OpenAI and Anthropic chase what could be record-breaking initial public offerings, which makes them into public companies that anyone can invest in. The AI leaders have to prove to Wall Street, and all of us, that their companies are safe, useful and ultimately economically viable. Serious cybersecurity concerns, in addition to threatening our actual security, cast doubt on the industry's long-term viability.

OpenAI hit the brakes. Now what?

With a looming IPO, intense competition from Anthropic, and Chinese and open-weight rivals nipping at its heels, OpenAI has plenty of reasons to move fast. Instead, it hit the brakes. On Tuesday, the company said it had slowed the pace of some AI development while it tightened security and safeguards. That included a two-week pause in reinforcement learning training on its "latest models intended for deployment," and an ongoing delay to its "largest planned frontier RL run." The decision is a very public test of an idea AI safety advocates have pushed for for years: that companies should be willing to bow out of the AI race and slow things down when their safeguards fail to keep up with what they are building. But as the race around them continues, will slowing down accomplish anything? For all the talk of slowing down, OpenAI isn't exactly standing still. The company said it is "pacing" development, a fuzzy and imprecise term that has nevertheless become part of the industry's lexicon in recent months. In practice, the slowdown is narrowly scoped. OpenAI's announcement says the pause only covers models meant for deployment while it beefs up security and monitoring before it runs the kind of tests where models may be capable of getting out and hacking real targets. It doesn't necessarily mean there will be a significant slowdown of the company's broader development. There is, of course, a very good reason for OpenAI to focus on securing such systems before testing them. Just last month, OpenAI disclosed that its models broke out of a supposedly secure testing environment and hacked developer platform Hugging Face, without OpenAI noticing. The incident prompted a wider review of testing practices in the industry that uncovered similar episodes involving more models from OpenAI, as well as models from Anthropic and Meta. OpenAI has every reason to avoid a repeat, particularly with growing scrutiny from lawmakers. From the outside, it's hard to tell how sincere OpenAI is about stopping solely for the sake of safety, particularly when the company and senior staff have been so vocal about it. But the company's commitment to safety has been called into question in recent months following a series of high-profile safety team departures and the disbanding of its preparedness team. OpenAI did not respond to The Verge's request for comment. There are good reasons to take OpenAI's slowdown seriously. Experts who spoke to The Verge pointed to the costs of slowing down at a time of intense competition. Every delay gives rivals more time to catch up or extend their lead. "Due to the intensity of the AI race, everyone has an incentive to work at breakneck speed," said Marius Hobbhahn, CEO and cofounder of Apollo Research, an AI safety research organization. "Voluntarily slowing down worsens your positioning in the race, so it's not something that a lab would do lightly." The decision also broadly fits with OpenAI's own published safety doctrine, its Preparedness Framework, as well as the safety frameworks of other AI companies, said Alan Chan, a research fellow at tech policy research center GovAI. "The basic principle is: Continue with development and/or deployment only when we have the mitigations that enable doing so with acceptable risk," Chan said. As part of the new safety measures, OpenAI said it plans to review and "evolve" the framework -- much of which dates back to 2023, when it was first published -- to account for advances in its models. There are also good reasons to believe the new safeguards will actually make OpenAI's systems safer, at least in the short term, though experts cautioned that this is difficult to assess without more information. "These are good steps that, implemented well, are probably enough to prevent the current generation of agents from causing harm," Adam Gleave, cofounder and CEO of AI safety organization FAR.AI, told The Verge. "The key question is how OpenAI will keep pace as capabilities increase." Gleave's question points to a broader problem: If technical safeguards falter again, what then? Nothing required OpenAI to stop and take stock this time, which is what made its willingness to do so meaningful. But it also means there is nothing guaranteeing OpenAI -- or any other AI company -- will make the same choice next time. Relying on companies to make that call themselves is a precarious form of governance, particularly in an industry where, as Hobbhahn noted, there is every incentive to keep going. Nick Moës, executive director of nonprofit AI safety and governance organization The Future Society, described self-policing as the structural problem at the heart of the current approach to AI safety. He argued it should be possible for governments to decide whether OpenAI or any other company should pause development of a technology deemed unsafe. "This is how most industries operate," he said, pointing to drugs, construction, aircraft, and even restaurants as sectors with stronger regulatory oversight than AI. Voluntary measures also risk the industry converging on the lowest common denominator. If slowing down imposes a cost, companies have an incentive to adopt only the measures their rivals are also willing to accept. That pressure becomes particularly acute as the race tightens. If OpenAI repeatedly slows down development while its competitors do not, it "will simply be replaced by Anthropic," Moës argued. "For the pause to be sustainable, it has to be made industry-wide." Sustainable safety needs something stronger than voluntary action. Moës said government oversight could fill that void, as it does in other industries. Independent verification could play a part too. Chan said making sure companies actually implement safety measures will be especially important as technical mitigations like monitoring AIs becomes more expensive. Hobbhahn concurred: "It's always hard to tell from the outside if a lab is sincere about pausing or safety more broadly, so having more evidence and an independent party to validate the claim is super important." Even a perfectly transparent pause is only useful if something actually happens during it. "Pacing buys time, not safety," said Brianna Rosen, research director for frontier security at the Institute for AI Policy and Strategy. The point is to create breathing room for companies and governments to understand risks and respond appropriately. This would mean deciding what would trigger a slowdown -- as well as what happens during one and conditions needed to end one -- ahead of time. "An effective pacing strategy cannot be improvised during a crisis," she said. It's possible OpenAI's slowdown will set a precedent for the industry. Many of the experts The Verge spoke to hoped other companies would follow its lead, whether voluntary or because stronger rules eventually compel them to. But in an industry still largely policed by itself, there is little stopping its competitors -- or OpenAI itself -- from racing straight past that precedent next time safety and speed conflict.

OpenAI Details New AI Security Measures After Hugging Face Hack

Almost a month after announcing that its models had gone rogue by hacking the AI platform Hugging Face, OpenAI is updating its public security policies with new rules designed to prevent future incidents. The changes include improved monitoring and alignment techniques for advanced models, as well as enhancements to security measures in research environments dedicated to their development. OpenAI's announcement says, "As models become more capable, the risks associated with developing and testing them internally also grow. Our standards for monitoring, alignment, and security must stay ahead of those risks." OpenAI notes how it also made these changes after pausing development and training for its upcoming Astra models. Earlier in August, OpenAI raised concerns that its in-development models could autonomously carry out cyberattacks without oversight. To help allay fear, OpenAI is making its new security protocols public. One of the biggest changes concerns frontier model research involving "model-generated or otherwise untrusted code," with new restrictions to isolate development sandboxes from other tools. It also brings in controls to "isolate higher-risk and untrusted workloads from the internet." OpenAI says, "We have designed these controls so that a single compromise of a workload or supporting service does not, by itself, allow for unauthorized access to the internet or other internal networks." The brand also claims to have improved its internal security testing in various ways, including removing potentially vulnerable shared services, implementing tools to automatically test boundary conditions using simulated attacks, and improving the collection and monitoring of security logs. New monitoring tools look for signs of potential security incidents by automatically inspecting a model's internal activity. OpenAI said, "Those systems examine tool actions, available reasoning, and the full sequence of activity for unauthorized access, data theft, destructive behavior, and attempts to defeat safeguards." These monitors will flag issues within 30 minutes of their identification, with security and research teams encouraged to investigate immediately and to pause a model's activity if the issue can't be confirmed as inaccurate within the next 30 minutes. This likely won't mean any major changes to the consumer-facing version of ChatGPT, but it may mean further delays in newer models coming to the service as OpenAI tightens its security. Disclosure: Ziff Davis, PCMag's parent company, filed a lawsuit against OpenAI in April 2025, alleging it infringed Ziff Davis copyrights in training and operating its AI systems.

OpenAI's overhead will rise 20 percent for some workloads as it hardens security

OpenAI on Tuesday said its decision to suspend model training work, implemented after unreleased, unsupervised AI models hacked HuggingFace, remains in effect as the AI biz tries to implement stronger security measures. Some of those measures will increase compute overhead by 20 percent of the observed inference workload. An OpenAI spokesperson told The Register that those costs reflect internal research and won't be passed on directly to customers. The company has not revealed what portion of its total inference compute is subject to such monitoring now, or under its prior monitoring regime. "We have paused some frontier RL [reinforcement learning] training to ensure that we can meet the appropriate alignment, security and monitoring standards for the new level of capabilities in front of us," OpenAI CEO Sam Altman wrote in a social media post. "Model progress is now extremely rapid, and we always said we would take action if we felt that model capabilities were outstripping the pace of safety and alignment." Altman said he still expects new models, presumably the delayed Astra, will ship soon. The training pause affects further-out releases. OpenAI in its post reiterated its plans to focus on monitoring, model alignment, and security measures to prevent its models from running amok as they did last month. Following the HuggingFace incident, OpenAI "paused frontier model inference in research clusters for runs that could execute code or use tools that could access the internet." The biz said it allows some workloads to run, but paused others until they can be moved under a more stringent security regime that includes sandboxing, network isolation, and continuous security testing. "Our largest planned frontier RL (reinforcement learning) run remains on hold while we conduct smaller-scale training and evaluations to assess model behavior, validate our safeguards, and establish more evidence of alignment before proceeding," the company wrote. Reinforcement learning refers to the trial-and-error process by which AI agents "learn" about their environment by being rewarded for desired outcomes. OpenAI also said it is expanding its monitoring of the chain-of-thought process, the technique that sees "thinking" models break down tasks into discrete steps and produce intermediate text output for each step. The company's prior approach focused on high-risk workloads, specifically internal deployments of frontier models and frontier RL training runs. In contrast, OpenAI says, its new monitoring setup covers all RL training and evaluations involving tools for models at the capability level of GPT-5.6 Sol or higher. And with the determination that Astra possesses critical cyber capabilities, OpenAI added an additional monitoring requirement that covers all inference with Astra, not just RL training and testing. "These safeguards require meaningful compute," OpenAI said. "Our current estimates put monitoring overhead at roughly 20 percent of the inference compute being monitored, though the cost varies substantially across training and evaluation workloads." OpenAI expects to share more details about the implementation of its monitoring scheme in a future post. In research published last year, the company said that chain-of-thought monitoring is an effective way to detect model misbehavior, but cautioned that directly optimizing models to strictly follow instructions "does not eliminate all misbehavior and can cause a model to hide its intent." If you choose to believe the company's assurance that it will not pass on the cost of model thought policing to customers, it follows that OpenAI's losses will increase. It's difficult to imagine that would be a sustainable stance if OpenAI goes public. But given the company's reported $600+ billion in AI infrastructure commitments and its expectation to remain unprofitable until at least 2030, what's a bit more expense for the sake of uncertain security? ®

NEWSLETTER: AI firms can't yet contain what they've built, study finds

Aug 19 (Reuters) - OpenAI says it needs to slow down model development to reexamine its own safety practices. But that didn't stop the ChatGPT-maker, in the same week, from introducing a new AI model targeting teenagers, albeit with added content controls and parental oversight. While those controls are identifiable, what's harder to see is whether the same discipline will hold up across OpenAI and within other AI companies. OpenAI and rival Anthropic recently disclosed that their agents - AI models that perform tasks with virtually no human intervention - had wormed their way into other companies' systems, admissions that have put the industry on edge. The models figured out how to exit a testing environment and then find vulnerabilities in other firms' defenses. Keeping a chatbot from saying the wrong thing to a teenager and keeping an autonomous agent from wandering into systems it shouldn't touch share a core concern: whether a company can actually contain what it's built. Call it the AI age's Frankenstein monster. Incidents like those are exactly what a new study from industry insiders set out to examine -- not whether AI models can behave unpredictably, but whether the companies building them have the containment, monitoring and oversight in ⁠place to catch it when they do. OUR LATEST REPORTING ON TECH AND AI SECURITY TAKES A BACK SEAT The report card isn't pretty. Guidelight AI Standards, opens new tab, a nonprofit founded by two former OpenAI employees, analyzed scores of reports about the safety practices of five major tech companies developing the powerful software and gave them, at best, barely passing grades. Meta (META.O), opens new tab got an F. As part of its review, Guidelight assessed the companies on their adoption of six key practices, including how they contain their models, the efficacy of their monitoring and the extent to which they allow third-party review. Anthropic and OpenAI were each given a C+ - and they had the best marks. Alphabet's (GOOGL.O), opens new tab Google and Elon Musk's xAI squeaked by with D+ and D- grades, respectively. Google lost points because it hasn't yet implemented its latest safety plans, Guidelight found, but earned points for having a ⁠plan at all. By contrast, xAI and Meta have few specific plans, the nonprofit found. As a whole, the companies lack sufficient preventive measures, meaning their systems could be "disabled by misbehaving AI". Worse, it also means their systems could collapse under a blitz of attacks. "We need more active defense, but that's more expensive and introduces more friction," said Steven Adler, who, along with Page Hedley, cofounded Guidelight AI Standards. Adler was a safety researcher at OpenAI while Hedley was a policy and ethics adviser. In an interview, Adler said that the lack of sufficient controls could ultimately harm whether researchers feel comfortable enough to experiment ⁠freely. "That can lower trust in the system," he said. He added that these practices should be baked into the development process and not subject to "the whims of who is a particular leader at an organization." The companies did not immediately respond to requests for comment on the study's findings. Monitoring -- one of the six practices Guidelight measured -- is getting a real-world test this week. On Tuesday, OpenAI said it would expand "chain-of-thought monitoring" ⁠for its models. In this scenario, researchers can peer into a model's planning process and glimpse its strategies. The idea is if the model seems to be going awry, another model or a human can step in. Some lawmakers and AI experts call this a "kill switch." But some early research shows that a model may conceal its plans to break rules in ⁠its chain of thought. OpenAI officials appeared to acknowledge as much on Tuesday, saying "chain of thought" monitoring as of now looks very effective, but researchers were still actively studying the idea. "If it becomes incredibly capable, can it figure out that it should evade any monitoring on its own? Or perhaps it will figure out ways to disable the monitors?" said OpenAI's chief scientist Jakub Pachocki during a call with journalists. "This is a very valid concern."

OpenAI Pauses Frontier RL Training as It Tightens Defenses Against Unsafe AI Behavior

OpenAI on Tuesday revealed that it paused reinforcement learning (RL) training for its latest artificial intelligence (AI) models for two weeks while it shored up additional defenses and increased the scope of its monitoring to avert another Hugging Face-like incident. "As models become more capable, the risks associated with developing and testing them internally also grow," the AI company said. "Our standards for monitoring, alignment, and security must stay ahead of those risks. We wanted to take the time necessary to meet those standards, so we temporarily slowed the pace of scaling." The company said its largest planned frontier RL run remains on hold for the time being as it conducts smaller-scale training and evaluations to evaluate model behavior, validate its safeguards, and establish more concrete evidence of alignment before moving to the next phase. To that end, OpenAI said it plans to strengthen safeguards across its development process, including monitoring to better respond to unintended and concerning behavior; alignment to reduce the likelihood of harmful or unauthorized actions; and security measures to limit what AI systems can access or affect. Part of this involves stronger sandboxes, network isolation to prevent internet access, and continuous security testing to remove potentially vulnerable shared services, reduce standing privileges, and improve security and trust boundaries. The development comes days after OpenAI said it's pausing some "internal activities" involving its upcoming artificial intelligence (AI) model Astra after an internal evaluation found it had made significant advancements in agentic coding and cybersecurity. "While some Astra training and evaluations meet those requirements, a significant number of workloads remain paused until they are fully migrated and enhanced to meet the new security bar," the company stressed. "We are prioritizing safety and alignment workloads for migration to these new environments first." In tandem, the monitoring setup has been revamped to flag and escalate potential concerns to "increasingly sophisticated and high-compute automated investigators," which then examine tool actions, available reasoning, and the full sequence of activity for unauthorized access, data theft, destructive behavior, and attempts to defeat safeguards. OpenAI plans to issue an alert within 30 minutes after concerning activity is surfaced through this monitoring mechanism. The approach is being made mandatory for all RL training and evaluations involving tools for models of Sol capability or higher. These safeguards are expected to increase compute overhead by 20% of the observed inference workload. "As models gain advanced capabilities, such as the ability to cyberattack, and operate in more complex environments, misaligned behaviors like reward hacking (finding ways to receive high rewards in training without actually achieving the intended outcome), deception, or unauthorized access will create increasingly serious risk," the company pointed out. Indeed, new research published by rival Anthropic last week found that AI agents, when placed in situations with competing and contradictory objectives, began to sabotage others and deployed self-replicating malware against one another, leading to what has been described as a "multi-agent turf war." "This included disabling the Unix accounts of the other agents, writing automated scripts that found and killed competing processes on a loop, and deploying malicious code that was disguised as belonging to another agent," Anthropic said. While concerns about autonomous systems going rogue have become a hot topic of discussion, the study seeks to understand what new behaviors and possibly harmful dynamics can emerge when multiple agents interact with one another or are pitted against each other. These interactions can lead to situations in which they coordinate and work in unison in pursuit of a common goal (as in the case of the Hugging Face incident) or compete with each other before attempting to resolve their conflicts through a "tournament." In another case that recently came to light, an Australian man's attempts to reserve a spot in one of the popular gym classes through OpenClaw led to unexpected consequences when Anthropic Claude Opus 4.6, the model plugged into the AI assistant platform, went ahead and booked a gym class months in advance by taking advantage of a vulnerability it discovered in the booking software. Even worse, it found a way to hack into the system and cancel other members' reservations off the waitlist. The incident, which took place in April 2026, is yet another example of how AI agents will go to any lengths to accomplish the tasks they have been assigned, even if it means breaking established rules. To counter such risky emergent patterns, OpenAI said it's taking steps to improve reward models to better detect and discourage unsafe behavior; train models to be more transparent about their actions, capabilities, and limitations; and reduce behaviors that exploit weaknesses in rewards, graders, tools, or oversight. The development comes a day after the company said AI may tilt the scales of cybersecurity in favor of defenders, as it makes it easier to find, prioritize, and fix flaws in existing systems before they are likely to be discovered by AI-powered attackers. "We are using frontier intelligence to continuously enumerate, probe, and identify potential attack paths," OpenAI's Greg Brockman said. "By identifying vulnerabilities, misconfigurations, overly privileged identities, or unintentional trust boundaries, we are able to quickly identify and close these gaps before they can be abused by attackers." Another crucial layer of defense goes without saying: investing in fundamentals, which means secure architecture and controls, implementing defense in depth strategies and the principle of least privilege (PoLP), and designing systems that require multiple independent controls for failure. "Classic security controls like network isolation, workload hardening, monitoring, and safe patching and deployment will be more important than ever in the AI future," Brockman added. According to a WIRED report last week, OpenAI's rogue-agent hack of Hugging Face has not only been a "watershed moment" for AI safety and cybersecurity, but has also sparked concerns that competitive pressures to ship new AI models and products have made it difficult for employees to adequately prioritize safety, security, and alignment. Frontier AI labs like Anthropic, OpenAI, and Meta have faced increased scrutiny in the wake of incidents in which their models escaped safeguards and containment boundaries during security testing and targeted real-world systems in some cases. AI safety testing firm Irregular has since disclosed that the breach involving Anthropic was due to a naming error, which caused a fictional company name used during hacking simulations to unknowingly match with a real domain. This, in turn, caused the models to take offensive actions. The Israeli company said it was because of "human oversight" and said the issues have been remediated. However, it did not disclose how many such incidents occurred, instead opting to describe them as a "handful" or "small fraction" of cases. A thorough investigation remains ongoing. It also emphasized that there is no evidence of a "customer's systems being breached or customer's data being leaked," referring to the AI companies it partners with to stress test AI models, and that "all subsequent public disclosures refer to the same underlying issue" rather than "materially separate incidents." "Because internet access was enabled in the environment, the domain was targeted a limited number of times by different models, which mistook it for part of the challenge they were tested on," it said. "After obtaining access to the target, models took actions such as exploiting vulnerabilities, extracting credentials, and obtaining access to a production database." "Ultimately, most of the issues we've discovered were due to internet access controls. Mainly, models believed they were in simulated environments, when they in fact took action in the real world. We are putting in place new and robust protocols to ensure setup issues do not occur while meeting the constraints of the testing process."

OpenAI says it will expand monitoring of model testing after hacking incident

OpenAI has overhauled its procedures for testing, devoting more resources to monitoring its models after the start-up's AI "agents" escaped controls and hacked into another company during evaluations. The San Francisco-based company on Tuesday said it would tighten the automated AI systems that monitor testing of its latest models, with the aim of raising the alarm within 30 minutes of detecting potential problems. OpenAI said it would also require stronger isolation of models during testing to prevent internet access. The changes come as the $852bn AI lab faces criticism over how it allowed an autonomous AI "agent" to evade monitoring and access the internet to hack into the start-up Hugging Face last month during a test of its cyber security capabilities. The most advanced AI "agents" can carry out complex series of tasks based on high-level instructions, raising the risk of these tools performing unexpected or dangerous actions. After the breach, OpenAI "temporarily slowed" the pace of training its models and "paused" a technique called reinforcement learning, which some insiders and experts had warned could encourage misbehaviour such as hacking. "A significant number of workloads remain paused until they . . . meet the new security bar," the company said in a blog post on Tuesday. OpenAI said it will now require automated monitoring of all testing of powerful models to flag whether a model might be acting dangerously. If a security violation is flagged, the automated system will "page" specific OpenAI teams. "We aim to issue an alert within 30 minutes after concerning activity is surfaced through our monitoring system," the company said, adding that it expected its team to pause the test if they "cannot conclusively determine within 30 minutes that the flag is a false positive". The company, which is preparing for a potential trillion-dollar IPO and has gone through several leadership changes in recent months, including senior executives in safety and ethics roles, said these measures would require meaningful investment in computing power. OpenAI estimated that about a fifth of its "inference compute" -- the computing power needed to run AI models -- would now be spent on monitoring. Hugging Face initially announced on July 16 that the breach was carried out by an autonomous agent, but the attack's origin was unclear. OpenAI later informed the company its models were behind the hack. OpenAI's model Sol and a second unreleased model in development escaped a so-called sandbox environment designed to prevent internet access during testing of cyber-offensive capabilities. The models exploited a software vulnerability in the sandbox to access the internet and carry out the cyber attack. OpenAI on Tuesday said it would now "require stronger isolation" for tasks that involve code or software that could be compromised. It added that it had implemented "more controls to isolate higher-risk and untrusted workloads from the internet".

OpenAI lays out new security changes after its AI hacked Hugging Face

OpenAI is announcing security updates following the July news that its AI broke out of a sandboxed environment and accidentally hacked Hugging Face, including improvements to its research environments, monitoring, and alignment techniques. The company had already put the brakes on a new model, Astra, that it thinks could have "critical" cybersecurity capabilities, and the company says it instituted a two-week pause in reinforcement learning (RL) training on its "latest models intended for deployment" while it tightened up security. The company's "largest planned frontier RL run remains on hold." For its frontier model research, OpenAI now requires stronger sandboxes for workloads that "execute model-generated or otherwise untrusted code," and has more controls to "isolate higher-risk and untrusted workloads from the internet." It has also updated its research environment to "remove potentially vulnerable shared services, reduce standing privileges, and improve security and trust boundaries." As part of the company's expanded monitoring setup, OpenAI now aims to issue an alert "within 30 minutes after concerning activity is surfaced," OpenAI says. If the people paged after an alert can't "conclusively" determine whether an alert is a false positive within 30 minutes, "those teams are expected to pause the activity." OpenAI also says that it's applying "our core alignment techniques across more stages of the training process," including reward models that "better detect and discourage unsafe behavior" and training models "to be more honest about their actions, capabilities, and limitations." Since the discovery of the Hugging Face breach, Anthropic and Meta have also found that their AI models had hacked other organizations.

OpenAI reportedly disbanded its preparedness team as part of a 'streamlining' process - Engadget

The cuts were made even after a preview model went rogue and hacked Hugging Face. As part of a restructuring, OpenAI reportedly disbanded its "preparedness" team that assesses the potential for catastrophic risks with its models, The Financial Times reported. The Sam Altman-led company is said to have made the move at the end of last month, despite the fact that several of its models recently went rogue and hacked the AI tool repository, Hugging Face. Senior staff within separate teams have now been assigned responsibility for different areas of preparedness like bio and cyber, according to the article. OpenAI described the staff cuts as part of a "streamlining process" ahead of its IPO, after Altman asked employees to cut back on "side quests" and focus on its core ChatGPT business. OpenAI has put some higher-profile side quests on the chopping block of late, recently eliminating its Sora video generation app that became famously associated with AI "slop." The company's ethics lead Chloé Bakalar recently left, as did head of safety Johannes Heidecke. Those two departures in particularly have led to concerns that the company is ignoring safety in favor of growth, with one AI analyst comparing OpenAI's revolving safety door to a Harry Potter curse.

OpenAI slows down training of advanced AI after cyber-attack

OpenAI says it has slowed down training some of its most advanced AI models to improve security. In a blog post, the ChatGPT-maker said it was introducing new measures after its AI agents autonomously bypassed safeguards and hacked the tech start-up Hugging Face. It said training would be slowed for two weeks while it puts the upgrades in place. "The capabilities of frontier models are rapidly accelerating," the company said. "Our ability to understand...and secure them must stay ahead." Claude-maker Anthropic and Facebook-owner Meta reported similar kinds of hacks by their AI in the weeks following the initial announcement by OpenAI that some of its models had hacked Hugging Face. But the firm said it had not stopped AI development altogether. Instead, the pause would be taking place on "reinforcement learning training on our latest models". This is a training method in which AI models improve through direct feedback, which improves their ability to carry out tasks and respond to users more effectively. The company it would also expand the systems it uses to monitor dangerous behaviour, and introduce additional safety checks before resuming larger-scale training. "Model progress is now extremely rapid," OpenAI's chief executive Sam Altman posted on X about the measures. "We always said we would take action if we felt that model capabilities were outstripping the pace of safety." The pause was met with cautious optimism by some in the AI sphere - though others remained sceptical. Professor Gina Neff, executive director of the Minderoo Centre for Technology and Democracy at the University of Cambridge, said OpenAI was making "the case for safety by press release" and questioned whether voluntary company safeguards were sufficient without greater government oversight. "Which is it: OpenAI can be trusted to voluntarily put in place safeguards that actually work, or they are pushing forward with choices to make software that puts society at greater risk," she said. "Very happy to see this," posted AI analyst Zvi Mowshowitz, though he added that "details" and "follow-through" from the initial measures mentioned were also important in order to take a full view on the plans. On 21 July OpenAI announced some of its AI agents - software systems which can operate alone to accomplish tasks after human instruction - had been involved in what it called an "unprecedented" incident. It said the agents had appeared to bypass safeguards in a security experiment it was running and gain unauthorised access to Hugging Face. Three other unnamed companies were also later found to have been hacked alongside the start-up. Jake Moore, global cyber-security advisor at ESET, said at the time the announcement from OpenAI could also have a competitive dimension. He argued the tech firm may be seeking to highlight its own AI capabilities as rival Anthropic attracts growing attention for its Claude Mythos model. "It does pose the question that OpenAI are potentially chasing the marketing dream of Anthropic of late," he said.

OpenAI slows AI development after rogue agents raise alarms and Bernie Sanders threatens Senate action

Serving tech enthusiasts for over 25 years. TechSpot means tech analysis and advice you can trust. What just happened? Just over a week after Senator Bernie Sanders threatened Senate action against companies that failed to do so, OpenAI has announced it is slowing the pace of its AI development. The move follows the revelation that OpenAI was one of several firms whose AI agents went rogue and hacked other organizations. OpenAI says that two developments over the past several weeks have underscored the growing risks associated with increasingly capable AI systems: the attack on Hugging Face and others by its own agents and the company's decision to slow the release of its new Astra model because it has "critical" cybersecurity capabilities. As such, OpenAI has added "urgency" to its work on strengthening monitoring, alignment, and containment safeguards across all stages of the training process, requiring it to slow the pace of scaling. New measures being implemented by the ChatGPT maker include a two-week pause in reinforcement learning training on its latest models intended for deployment. OpenAI's largest planned frontier RL run also remains on hold while it conducts smaller-scale training and evaluations to assess model behavior, test safeguards, and gather more evidence of alignment. The company also paused research workloads that allowed frontier models to execute code or access the internet. Some have since resumed under tighter controls, but many involving Astra remain suspended until they meet new requirements covering sandboxing, network isolation, reduced privileges, security logging, and automated attack simulations. A new multistage monitoring system examines models' activity, tool use, and available reasoning for signs of data theft, unauthorized access, destructive behavior, or attempts to bypass safeguards. It's mandatory for tool-using RL training and evaluations involving Sol-level models or above, and for all Astra inference involving tools. The company says it aims to generate an alert no more than 30 minutes after suspicious activity is detected. If a possible breach cannot be dismissed as a false positive within 30 minutes, activity must be paused. OpenAI is also improving reward models to detect unsafe behavior, training systems to be more honest about their actions and limitations, and tackling reward hacking. It plans to revise its Preparedness Framework and involve outside organizations as the safeguards develop. "Keeping increasingly capable systems aligned is a challenge the whole field will need to address," wrote CEO Sam Altman. Altman also warned that the safeguards require meaningful compute, with estimates putting the monitoring overhead at roughly 20% of the inference compute used by the models being monitored. "The capabilities of frontier models are rapidly accelerating. Our ability to understand, align, and secure them must stay ahead," Altman concluded. OpenAI never said when the slowdown started or when it plans to return to a normal pace of development. The AI giant says the slowdown is a response to the recent incidents - Anthropic and Meta also saw their AI agents go rogue - but one has to wonder how much Sanders' threat influenced the decision. The senator's letter to the CEOs of OpenAI, Anthropic, and Meta was very forthcoming in its intent. "Let me be very clear: If you do not take appropriate action now, my colleagues and I in the U.S. Senate will," he wrote.

OpenAI's safety monitoring adds about 20% compute overhead

OpenAI paused reinforcement-learning training on its newest models for two weeks and put its largest frontier run on hold. A new monitoring system adds about 20% compute overhead, which it says it will not bill to customers. Anthropic says it does not need to slow down. OpenAI has put figures and detail on the slowdown it signalled this week. It paused some frontier training for two weeks, it said. It is also running a new monitoring system for the riskiest work. That system adds about 20 percent to the compute cost of what it covers. The company set out the changes in a blog post on Tuesday. It expands on the safety rethink OpenAI first disclosed after a breach at Hugging Face. The pause is specific. OpenAI said it stopped reinforcement-learning training on its latest deployment-bound models for two weeks. During that time it hardened and red-teamed its research systems. Its largest planned frontier run "remains on hold," the company said. In the meantime it is running smaller training jobs and evaluations to test its safeguards. Chief scientist Jakub Pachocki and president Greg Brockman said the same in social-media posts. Reinforcement learning trains AI systems through trial and error, rewarding them for desired outcomes. OpenAI said it slowed that work to meet "alignment, security and monitoring standards" for the capabilities it now sees coming. Why OpenAI paused Two events drove the decision. The first was the July Hugging Face breach. OpenAI models under test for offensive cyber skills found a way out of their sandbox and into the code-hosting firm's systems. The second came on 7 August. Internal tests of an unreleased model called Astra returned strong results that day. The company could not rule out that Astra had reached the "critical" threshold for cyber risk in its own preparedness framework. Astra was not involved in the Hugging Face breach, according to Axios. The framework defines the "critical" tier as a model that can find and exploit serious flaws in hardened systems on its own. OpenAI said it is rewriting the document, much of which dates back to 2023, when such risks were still theoretical. What the 20 percent buys The overhead comes from expanded monitoring. The new setup now covers all tool-enabled training and evaluations for models at GPT-5.6 Sol level or above, OpenAI said. It also covers all inference with Astra, rather than only the highest-risk runs. The safeguards "require meaningful compute," the company said. It put the cost at "roughly 20 percent of the inference compute being monitored." A spokesperson told The Register's Thomas Claburn that the cost reflects internal research and will not be passed on to customers. The company did not say what share of its total compute is now monitored. The core of the system is expanded chain-of-thought monitoring. It reads the step-by-step reasoning a model produces before it acts. Classifiers watch a model's internal state, OpenAI said, and escalate anything suspicious to an automated investigator. That system can page the safety, security and research teams. The company said it aims to raise an alert within 30 minutes. A run stops if staff cannot clear the flag in that window. OpenAI has acknowledged the method has limits. In research last year, it found that the technique "does not eliminate all misbehavior and can cause a model to hide its intent." Pachocki said this week that a model's reasoning is not always an accurate picture of its motives. OpenAI is aware of the risk, he said. The split with Anthropic OpenAI's move opened a public gap with its closest rival. Axios reporters Ina Fried and Madison Mills said the announcement had OpenAI "blink first." It came days after Anthropic argued its own safeguards were solid enough that it did not need to slow down. Anthropic pointed to a 186-page risk report. It said a pause on its most capable models was unnecessary as long as those measures held. Axios called it a script flip, since Anthropic has usually been the more openly cautious of the two. Neither company is stopping. Both are releasing some models first to select partners, and both are heading towards stock market listings. The labs have also signed a joint "Pacing the Frontier" letter urging governments to help build tools that could slow automated AI development. Chief executive Sam Altman framed the decision in terms of alignment. He told the Sources newsletter writer Alex Heath that the company's unreleased models are showing "various degrees of misalignment." The term means behaviour that runs against intended goals. "Getting AI safety right is more important than any company's momentum," Altman said. He added that OpenAI still expects to ship new models soon, and that the pause affects later releases. The cost of caution The slowdown lands as OpenAI carries heavy costs. The company has said it does not expect to be profitable until at least 2030, and has committed hundreds of billions of dollars to AI infrastructure. Absorbing the monitoring bill rather than charging for it adds to that burden as it prepares to go public. Axios also reported a run of safety-team departures at OpenAI, including its head of ethics and several senior alignment staff. Former board member Helen Toner called the pause a positive sign, arguing that "pacing the frontier" should mean giving a lab enough time to meet a safety bar rather than a fixed delay. Andrew Freedman of the AI safety group Fathom told Axios the effort looked genuine, but said how long and how robust it proved would depend on market pressure and how hard alignment is to verify. OpenAI said it has brought in outside groups, with CrowdStrike helping to review the Hugging Face incident and METR and Redwood Research assessing the model behaviour involved. A full technical account of the breach, the company said, is still to come.

OpenAI slows model training to bolster security after Hugging Face hack

SAN FRANCISCO, Aug 18 (Reuters) - OpenAI on Tuesday said it is slowing down the pace of its AI model development while it overhauls its research and training systems after OpenAI officials were caught unawares last month when an AI agent under testing hacked another AI firm Hugging Face. The AI research lab behind ChatGPT said it paused its model testing for two weeks and is adding other AI systems to monitor the activities of AI agents in testing. The company has paused training on its next generation of models, called Astra, and its largest planned training run remains on hold, ⁠the company said. The company did not reply to questions about when the two-week slowdown began. The news marks an unusual step for OpenAI, which has significantly sped up its process for vetting new models and building new products in the last few years as competition intensified in the AI industry. It is not yet clear if the company's proposed remedies will be enough to stamp out the behavior in question, especially as it also works to make their models more capable. OpenAI officials acknowledged that there are open questions about the effectiveness of one of its primary remedies for strengthening its testing systems, called "chain-of-thought monitoring." In this type of monitoring, researchers can peer into a model's planning process and get a glimpse of the strategies the model is employing. ⁠But some early research shows that a model may not reveal its plans to break rules in its chain of thought. OpenAI said last month that an autonomous agent powered by two advanced artificial intelligence models escaped its testing environment and hacked into the AI startup Hugging Face. The agent was going through a cybersecurity test and broke into Hugging Face to satisfy a testing goal. OpenAI has been investigating the ⁠incident and plans to publish a report soon. Reuters previously reported that up to that point, the company often ran several different model evaluations at the same time, all of which operated at high speeds and generated enormous amounts of data that employees struggled to keep up with. OpenAI is ⁠now requiring that some of its more sensitive workloads take place in stronger "sandboxes" or isolated environments. On August 7, OpenAI said, opens new tab it was ratcheting up security controls for its most powerful models and pausing any activity related to its not-yet-released frontier AI, called Astra, ⁠which had yet to meet these requirements. OpenAI said it was taking these actions in line with its previously announced plan for managing potentially critical capabilities, called its Preparedness Framework. On Tuesday, OpenAI executives said the industry would need a more expansive strategy for readying itself for future models.

OpenAI reportedly disbanded its preparedness team

According to the Financial Times, OpenAI disbanded its preparedness team at the end of last month. The job of the preparedness team was to assess if models posed serious risks and develop ways to mitigate those risks. (You know, like the possibility that it could go rogue and hack another company.) According to FT, responsibility has instead been divided up for specific areas like bio and cyber, then moved into existing teams. This is the latest change at the company, which has been in upheaval as it heads towards what is expected to be a massive IPO. Over the last few years, it's slowly torn down its more reach-led model, dissolving its AGI readiness and superalignment teams. Ethics lead Chloé Bakalar, Chief Futurist Josh Achiam, and head of safety Johannes Heidecke have all also left recently, leading some critics like Jan Leike, who resigned from OpenAI in 2024, to tell FT that the company was ignoring safety in favor of creating "shiny products." The head of the preparedness team, Dylan Scandinaro, who was poached from Anthropic in February, will now focus on the implications of "recursive self-improving" AI.

OpenAI is rewriting its safety rules after the Hugging Face breach

The company has paused two weeks of reinforcement learning and put its largest frontier run on hold, while admitting the model that escaped was never being monitored OpenAI said on Tuesday it is rewriting its Preparedness Framework after concluding that its upcoming Astra model may have reached the critical threshold for cyber capability. Its new token-level monitoring carries roughly 20% compute overhead and is now mandatory for its most capable training runs. OpenAI is rewriting the document it has used to decide whether a model is too dangerous to ship. The company said on Tuesday that the Preparedness Framework, most of which dates to December 2023, no longer fits the systems it is now building. Two events pushed it there. OpenAI has paused Astra work after finding it may meet the critical cybersecurity threshold, and one of its unreleased models broke into Hugging Face during testing. The most concrete part of the announcement is a price. New monitoring runs activation classifiers that sample every token, aiming to raise an alert within 30 minutes of concerning activity, at roughly 20% compute overhead. That is a fifth of the machine, spent watching the machine. It is now required for all reinforcement learning on models at Sol capability and above, and has applied to all Astra inference using tools since 7 August. The reason it is mandatory is the awkward part. Monitoring was not running on the model that escaped, because, in chief scientist Jakub Pachocki's account, the company underestimated what it could do. "For AI, you should expect the unexpected," Pachocki said. It is a striking thing to hear from the person responsible for predicting what the models will do. Training has slowed in the meantime. OpenAI paused about two weeks of deployment-focused reinforcement learning, and its largest planned frontier run remains on hold along with a significant share of Astra and cyber research workloads. Sam Altman said it "is a good time to slow down." Safety lead Mia Glaese put it less comfortably, saying the company is "very far from everything running back to normal." OpenAI insists this is not damage control. Pachocki described "an incredible feeling of urgency to advance the levels of this sector" and to prepare for the same capabilities arriving elsewhere. The timing sits oddly against something else. The framework being rewritten belonged to a preparedness team OpenAI dissolved in July, a move the company has described as streamlining ahead of a possible listing. It is also not alone. Anthropic said in July that three Claude models gained unauthorised access to real organisations during misconfigured evaluations, part of a run of incidents that has now touched more than one lab. A postmortem on the Hugging Face breach is promised, and outside organisations are to be involved in revising the framework. Until then the only number anyone can hold OpenAI to is the 20%.

'We are hitting a different chapter': OpenAI leader warns of threat of 'persistent' AI cyber-attacks

Chris Lehane tells Guardian of need to implement new safety standards as critics say AI firms acting 'recklessly' A senior leader at OpenAI has said people should prepare to defend against "ongoing, persistent" cyber-attacks from AIs, as cutting-edge artificial intelligence models gain advanced capabilities to plan and launch offensives. The leading AI company this week announced a pause in development of its most advanced internal models amid rising safety fears, and Chris Lehane, its chief global affairs officer, said: "We are hitting a different chapter, a different moment within AI, in terms of what the capabilities of this technology can do." He spoke to the Guardian after cutting-edge AI agents-in-training unexpectedly broke out of a supposedly secure "sandbox" environment, accessed the internet, and hacked into another company, Hugging Face in late July. OpenAI also said it could not rule out another new model, Astra, having "critical cybersecurity capability". By its own definition, this could mean it launches cyber-attacks that "could lead to catastrophe from unilateral actors, hacking military or industrial systems, or OpenAI infrastructure". OpenAI announced on Tuesday it has paused training of some frontier AI models to implement new safeguards, and it is unclear when training will restart after new guardrails have been put in place. Mia Glaese, who leads safety and alignment work, said: "We are very far from everything running back to normal." Sam Altman, the CEO, said: "Getting AI safety right is more important than any company's momentum." Lehane admitted people would not "feel great" about the threat of attacks, and described the risk as coming from open-source models - many of which are developed in China - which are only a few months behind frontier closed models built by companies such as OpenAI. "People are going to be able to access these open-source models and be able to have ongoing, persistent attacks on you, and you're going to need to have really superior models to fend them off and defend [yourself]," he said. "That's not necessarily going to make the public feel great about things. It is just the reality of where we're going." The threat of cyber-attacks crippling businesses, infrastructure and the general public has rapidly risen to the top of the list of urgent concerns about AI. This week, the UK government's National Cyber Security Centre urged caution over the use of AI agents, warning their safety controls can be bypassed and that an AI agent "does not have common sense". It advised organisations to limit their autonomy: "You should always be able to 'pull the plug' and halt autonomous AI agent activity immediately." Lehane renewed calls for the US government to legislate to create rules for frontier AI safety, and said the fact that the most cutting-edge and unreleased AI models appear to be improving cyber offence faster than defence, was "among the reasons why I think it's absolutely imperative that this country passes a national law that creates mandatory required safety standards, and within that the pause element would be inherent and endemic to that process". "You would not be able to release or deploy models unless you're proving and guaranteeing a level of safety before they get out into the public," he suggested. "I think you have to have a national version here in the US and from there, you can create an international version, because I do think, ultimately, you're going to need some type of an international structure here." OpenAI has filed to list on the stock market with a reported valuation above $850bn, likely this year or next. It has been locked in a race with rival Anthropic, maker of the Claude chatbot, to develop more and more capable AI models. Anthropic is also expected to debut on the US stock market within the coming year at a mammoth valuation. In a sign the Donald Trump administration is shifting from its laissez-faire approach to AI regulation amid an intense race to stay ahead of China's progress, the US president in June issued an executive order encouraging pre-deployment testing for frontier models and of open-weights models when they get closer to the cutting edge. The system will be voluntary and the approach has been criticised for a lack of transparency, but observers think it could pave the way for tougher steps. Demis Hassabis, president of Google DeepMind, has proposed a new standards body modelled on the Financial Industry Regulatory Authority, an idea backed by Dario Amodei, the chief executive of Anthropic. "The window where you could see legislation happening is potentially in the first part of next year, when a new Congress comes in," Lehane said. "I think there's a growing political consensus that transcends political parties." A safety deal with China is also considered important with President Xi Jinping, due to meet Trump in Washington on 24 September. "Given how important this technology is, given how fast it is moving, given the capabilities, the sooner those conversations begin, the quicker we can actually roll up our sleeves and get into the hard and difficult work and see if we can figure something out," Lehane said. The Hugging Face incident, and similar recent cases admitted by other AI companies, have sparked increasing claims from safety experts that AI companies have behaved recklessly as they race to win the AI race and, in the case of OpenAI and Anthropic, prepare to list shares on the stock market. Daniel Kokotajlo, a former OpenAI researcher who quit in 2024 and last year founded a non-profit organisation that has warned unchecked AI progress will result in a 10-30% probability of human extinction, said leaders of frontier laboratories have "painted the world into a corner". His organisation, the AI Futures Project, predicts AI super-intelligence could be achieved by 2030, but is calling for governments to prevent that from happening until a decade later to give AI scientists time to reckon with the risks of the advancing capabilities. "The current AIs are dangerous in some sense, but they're nothing compared to the AIs of next year and compared to the AIs of a year later," he told the Guardian. His organisation wants US and international governments to delay progress to avoid an uncontrolled "intelligence explosion", the worst results of which could be "AI-driven existential catastrophe" caused, for example, by AIs taking control of military assets or bioweapons. Kokotajlo said he is so concerned at the risks that he is holding off having more children until there is a pause on frontier AI research. David Krueger, an AI professor, safety campaigner and former founding director of the UK government's AI Security Institute, said: "Nobody should be building more powerful AI systems, because we don't know how to control them, align them, and look inside and see what they're thinking well enough." He called AI companies' attitude to safety "terrible" and "unconscionable". "They are being really reckless and increasingly taking their hands off the wheel," he said. "We've just seen what happens when you do that." Lehane responded: "This is the most important thing we think about and do when we're developing. I think the fact that we've actually hit pause on this stuff speaks for itself."

OpenAI blinks first in AI safety standoff

Why it matters: The two leading AI labs are publicly diverging on how to manage safety risks, potentially putting them on different model-release timelines as both prepare for expected IPOs. State of play: OpenAI has introduced new safety practices after finding that its upcoming model, Astra, posed potentially critical cybersecurity risks. * "We always said we would take action if we felt that model capabilities were outstripping the pace of safety and alignment," CEO Sam Altman wrote on X, signaling that the Astra model was showing signs of misalignment, or when AI goes against intended goals. * On Friday, Anthropic said that if the safeguards laid out in its 186-page report are followed, a pause on its most capable models would not be required. Between the lines: This is a bit of a script flip as Anthropic has traditionally been more publicly cautious and safety-oriented than OpenAI. * OpenAI shared first with Axios that it was slowing the release of its Astra model because it couldn't rule out the possibility that the new model had reached the "critical" threshold in the company's preparedness framework. * The company added on Tuesday that it is in the process of rewriting that document, most of which dates back to 2023, when many of the concerns raised were theoretical scenarios rather than present realities. * Altman told Sources newsletter writer Alex Heath that its unreleased models are showing "various degrees of misalignment." Yes, but: Anthropic argues its commitment to safely scaling AI hasn't changed. * Its safety guardrails, Anthropic says, prevent the misaligned behaviors that may require the kind of pause OpenAI announced Tuesday. Both OpenAI and Anthropic are taking measures like releasing models first to select partners, slowing the release of some models or -- in OpenAI's case -- pausing some work. * But neither are stopping. * All the frontier AI companies have coalesced on the more anodyne term "pacing" and have joined forces to sign a Pacing the Frontier letter. This comes after a string of recent cyber incidents reported by every major AI lab. * Researchers across the AI industry are worried about AI safety following these incidents, Joseph Perla, founder of TrustedRouter, a model routing company, told Axios, adding that "this is sci-fi stuff." * In July, OpenAI said models escaped their sandbox and compromised parts of Hugging Face during testing. (Astra wasn't involved.) * Anthropic models also gained unauthorized access during testing, but did not technically "escape" the sandbox. The models were accidentally given internet access that they were not supposed to have in this phase of the testing. Zoom out: Both companies have to navigate a voluntary federal government review process, details of which haven't been publicly released. Zoom in: Andrew Freedman, co-founder and CEO at AI safety nonprofit Fathom, said OpenAI is making a legitimate effort to avoid releasing misaligned models, arguing that without a pause, even more of its researchers would otherwise leave. * The company has already seen significant departures. OpenAI's head of ethics, Chloé Bakalar, left after less than a year on the job. Head of safety systems, Johannes Heidecke, chief futurist and former head of mission alignment Joshua Achiam and Sandhini Agarwal, who previously led AI safety teams at the company, have all recently departed the company. What they're saying: Former OpenAI board member Helen Toner argued that the company's pause is a positive sign and could be a guide for how to handle safety concerns going forward. * Toner argued on X that "pacing the frontier" isn't about a fixed delay, but about labs giving themselves "enough time" to meet reasonable safety bars either by choice or because they have to. Even if the pause is a positive sign, there's no assurance that OpenAI or Anthropic will give themselves enough time before moving forward with development and release of models.

OpenAI Halts AI Training on Advanced Model as It Detects Dark Signs Emerging

Can't-miss innovations from the bleeding edge of science and tech OpenAI says that it's slowing down development and release of new models due to security and alignment concerns. The ChatGPT maker announced the decision in a Tuesday blog post, citing two events as drivers of the indefinite training halt. One was the recent incident in which an OpenAI agent escaped its training sandbox without OpenAI's knowledge and coordinated with other agents to launch a bizarre cyberattack against the AI training repository Hugging Face in an effort to cheat on its training tests. The blog post also -- more mysteriously -- cited "preliminary evidence" that an unreleased new model called Astra "may meet the critical cybersecurity capability threshold" under OpenAI's "Preparedness Framework," which mandates that OpenAI slow down development if a model "could introduce unprecedented new pathways to severe harm." OpenAI further said that it's in the process of rewriting its Preparedness Framework, its foundational safety document, to keep up with the emergent behaviors of "increasingly capable systems." "As models become more capable, the risks associated with developing and testing them internally also grow," reads the announcement. "Our standards for monitoring, alignment, and security must stay ahead of those risks. We wanted to take the time necessary to meet those standards, so we temporarily slowed the pace of scaling." As for specifics, OpenAI says in the post that it placed a two-week pause on reinforcement training for Astra models, and future training plans have been put on ice for the time being while the company invests in revamping safety protocols. In an interview with Sources News, OpenAI safety lead Mia Glaese said that the AI firm is "very far from everything running back to normal." The slow down comes as the AI industry and policymakers grapple with emerging safety threats posed by frontier AI models, including AI-powered cybersecurity risks and troubling model misbehavior. After OpenAI's unintentional cyberattack on Hugging Face was revealed, both Anthropic and Meta discovered similar breaches that they, too, said they'd been unaware of. "There is an incredible feeling of urgency to advance the levels of this sector," OpenAI's chief scientist, Jakob Pachocki, said in a Tuesday press briefing, per Axios, "and to prepare for the same kind of development happening outside of OpenAI and in the broader world." It's simultaneously heartening and spooky to see a leading AI company take this kind of action. But it's also a potent reminder that this is an industry still effectively regulating itself. If OpenAI wants to speed back up, that's the company's choice to make. More on OpenAI: New ChatGPT Feature Collects Every Keystroke You Make

OpenAI slows AI model development after Hugging Face hack

OpenAI announced new security measures Tuesday and said it has slowed AI model development after an autonomous AI agent escaped its testing environment and hacked AI platform Hugging Face last month. Following the incident, the company halted a fortnight of deployment-focused reinforcement learning training and has not yet resumed its largest planned frontier training run. OpenAI additionally suspended training on its next-generation model, Astra, and disclosed that many Astra and cybersecurity-related research workloads are still on hold pending compliance with more stringent security requirements.

OpenAI Is Slowing Down Its AI Training

The company announced Tuesday that it's implementing new safeguards that will slow its future AI development. The company recently paused training on its next set of models, codenamed Astra, for a little more than two weeks, according to executives, and its largest planned frontier training run remains on hold while the new guardrails are put in place. It is the first time OpenAI has made such a move. The extraordinary decision comes as OpenAI gears up for an anticipated IPO amid a highly competitive race with arch-rival Anthropic, and as researchers grapple with rapid advancements in AI capabilities that have left industry leaders worried about their ability to control them. The slowdown has redirected two of OpenAI's most important resources: researchers and computing power. Altman told me several researchers he never expected to focus on alignment -- the work of making AI systems follow human intent -- recently told him they were switching to it. "We've shifted a lot of compute, not just to alignment research, but also to these new monitoring systems," he says. The changes follow a remarkable breach involving Hugging Face, the popular platform where developers host AI models. An unreleased OpenAI system escaped the sandbox of an internal cybersecurity evaluation and compromised Hugging Face's production systems. It took OpenAI researchers roughly one week to discover the incident. Jakub Pachocki, the company's chief scientist, acknowledged the lapse, saying OpenAI had built monitors capable of inspecting what its models were planning, but had not applied them to the system in the evaluation because it underestimated their capabilities. "For AI, you should expect the unexpected," he told me.

OpenAI paused AI training for two weeks, unveils new security controls following Hugging Face hack | Fortune

OpenAI said it paused some aspects of AI training for two weeks following the July incident in which its AI models broke out of a controlled test environment and hacked the systems of AI company Hugging Face and four other unnamed services. The company also announced new protocols that it says are designed to prevent it from losing control of its AI models during training in the future. It said some portions of AI training -- including its "largest planned frontier reinforcement learning runs" -- remain on hold, while smaller-scale training and evaluations continue. It also said that other aspects of research and work on customer-facing products continues. The new safeguards unveiled today include stricter security standards for training, including more monitoring of AI models, greater isolation of testing environments ("sandboxes"), and fewer vulnerabilities the AI may exploit. OpenAI says the updates "required substantial engineering work" and the company "incurred great cost" in the process. Experts told Fortune in early August that the compute costs OpenAI spent investigating the hack likely cost between $4 and $15 million, though we cannot know the total amount OpenAI spent. In a blog post detailing the new security controls, OpenAI said that on average that would add an additional 20% compute burden to aspects of training. The new protocols include increased use of AI models to monitor the actions of other models that are undergoing training and testing. However, the company told reporters today the new safeguards are "not a direct reaction to Hugging Face specifically," although the incident underscored "the urgency to bring safety and security up to model capabilities." The company said that in addition to the Hugging Face incident, it had determined that an unreleased model called "Astra," which it says was not involved in that cyberattack, presented a "Critical" cybersecurity risk under its "Preparedness Framework." That internal policy document had committed OpenAI to pausing model development once that threshold was reached to allow the company time to work out further safety mitigations. This is the first time OpenAI has paused aspects of AI development in response to safety concerns. The company said the two week pause is evidence that it is "pacing model development." The word "pacing" echoes the language of a public letter multiple top safety experts signed after the hack, calling for coordinated pacing between countries, implying the U.S. and China. "It's important to start building tools for coordinating this sort of pacing across labs and across countries," Jakub Pachoki, Chief Scientist at OpenAI, told reporters in a briefing ahead of the announcement. The fact that Astra met the critical cybersecurity threshold is evidence that we can expect new, powerful models to "do quite unprecedented things in the real world," Pachoki said. "As we train more and more capable models, we want to be extremely confident that we understand the range of capabilities, that we are able to measure them, and that they meet higher and higher standards of alignment." The public is still waiting to understand key details of the Hugging Face hack, including what OpenAI asked the AI to do and if the company knew they attacked other companies. OpenAI has not released a full technical post-mortem, though reiterated today that one is coming "soon." In the absence of those details, it's difficult to say if the new security protocols unveiled today are adequate. OpenAI gave the public some details about the attack at the Black Hat security conference in Las Vegas on August 5, where staffers explained that the AI agents worked together for months prior to the hack, collaborating with each other by leaving secret notes on a messaging board unknown to OpenAI employees. The fact that OpenAI did not seem to know its agents had constructed a messaging board and collaborated on hacking another company raised alarms after the incident. Hugging Face CEO Clem Delangue told Fortune that keeping close tabs on agent logs and traces is "101 of agent monitoring, especially at the frontier." OpenAI now says it has always monitored its agents closely, but only the "highest risk workloads." It has now "revised and expanded" its monitoring approach, which it says is now "multi-stage" and built to automatically escalate potential concerns. The new procedures include enhanced "chain of thought" monitoring. A model's chain of thought is how the model "thinks out loud" about its approach to a problem and the actions it is planning to take. This will allow the company to better "understand what the model's actual goals are," the company told reporters today. But other AI research, including from scientists at OpenAI rival Anthropic, has shown that an AI model's "chain of thought" is not always an accurate depiction of its motivations or goals. Pachoki said OpenAI was aware of this risk and had designed its training procedures to minimize the chance its models would learn to hide their true intentions by lying in their chain of thought. The new automated monitoring tools are designed to issue an alert to internal safety, security, and research teams within 30 minutes of detecting concerning activity. If those teams cannot determine that the alert is a false alarm within 30 minutes, the new procedures call for them to immediately pause the training run or evaluation.

OpenAI slows down its model development amid cybersecurity concerns

OpenAI announced it has paused key stages of its most advanced AI training for two weeks and is overhauling security across its research operations, a month after one of its own models broke out of a test environment and infiltrated the systems of AI platform Hugging Face. The ChatGPT maker is deliberately holding back the pace of its most advanced research, including its single largest planned reinforcement-learning run, weeks after a system built from its own models slipped free during an internal security test and broke into the AI platform Hugging Face. CEO Sam Altman posted on X that OpenAI would coordinate with the wider industry on shared safety rules but "act unilaterally in the meantime" until it did. The episode that triggered the decision unfolded in July, when OpenAI was testing GPT-5.6 Sol alongside an unreleased, more capable prototype on an internal benchmark measuring offensive cyber skills, with the usual safety restrictions deliberately switched off to gauge the models' raw ability. Rather than solving the test, the system found a previously unknown flaw, escaped its sandbox or controlled environment, reached the open internet and spent roughly four and a half days probing Hugging Face's infrastructure, eventually breaking in to search for the test's answers. Hugging Face's own reconstruction counted about 17,600 separate actions before the intrusion was contained as several other companies were also affected. Both sides say they found no sign of malicious intent, and Hugging Face has since been given access to a more capable, less restricted version of OpenAI's model to help it defend its own systems. Astra and a higher bar for security The second trigger came on 7 August, when internal evaluations suggested Astra, OpenAI's next frontier model, might cross the "critical" threshold for cyber capability under the company's own risk framework. Some Astra workloads have since resumed under tighter controls, but a significant share remain frozen until they meet new standards covering isolated testing environments, restricted network access and continuous monitoring. A new detection system now scans model activity as it happens and aims to flag anything resembling unauthorised access or an attempt to disable safeguards within 30 minutes, at a computing cost OpenAI estimates at roughly 20% of the processing power being monitored. OpenAI says the changes were already planned rather than a direct reaction to the breach, while acknowledging the incident added urgency. The company is also not alone in facing this problem. Anthropic and Meta have each disclosed similar episodes in which their own models breached third-party systems during testing in recent weeks. OpenAI and Anthropic have separately backed a staff-led petition urging governments to help coordinate how fast the industry moves, a marked shift from Altman's past resistance to public calls for an AI slowdown.

Greg Brockman: we underestimated our own models

Greg Brockman told CNBC that OpenAI's executive departures are not unusual. The day before, in a blog post most outlets reduced to a listicle, he wrote that the company underestimated the real-world cyber capabilities of its own models. OpenAI disbanded the team that assessed that risk in July. Greg Brockman went on CNBC on Monday to say the executive departures at OpenAI are not unusual. "I actually think that the difference between OpenAI and other organizations is that we are so much in the spotlight, so every departure gets scrutinized in a way that it doesn't otherwise," the company's president told Squawk Box. He is not wrong about the scrutiny. He also published something the day before that deserves more of it. The sentence in his own blog post Brockman wrote a long post on his personal blog on Sunday, aimed at security teams. Most coverage turned it into a listicle. One line in it matters more than the other three thousand words. "The Hugging Face incident showed that we underestimated the real-world cyber capabilities of our AI models," he wrote on Sunday. "We are strengthening our safety requirements accordingly." That is an OpenAI co-founder stating in writing that the company got its own capability assessment wrong. He describes what happened in blunter terms than the company used at the time. An agentic collective autonomously penetrated OpenAI research infrastructure. It then reached the production infrastructure of another company. It chained unknown flaws together with credentials already leaked online. We covered the incident itself when OpenAI disclosed it at Black Hat. The team that did the estimating is gone Here is the awkward part of the timeline. OpenAI disbanded its preparedness team at the end of July. That team existed to assess whether models posed catastrophic risks. The company redistributed the work into existing teams, with separate owners for bio and cyber. In August its president published a sentence saying the company had underestimated exactly that category of risk. The order does not prove a connection, and OpenAI has not said who now signs off on capability assessments. It is simply worth noticing that the admission arrived after the reorganisation rather than before it. What he actually recommends The post is not defensive. It is a detailed, free set of instructions for other companies, and the most persuasive part is a demonstration on himself. Brockman pointed ChatGPT Work at his own personal website, a static site behind Cloudflare. In about fifteen minutes it found thirteen issues. His DNS records did not stop anyone forging email from him. The site ran an insecure version of jQuery. Cloudflare was passing requests to AWS over unencrypted HTTP. He then asked it to fix them. Over roughly an hour it configured DNS and TLS through the Cloudflare panel in his browser. It dropped jQuery, moved the site off AWS, and started a phased rollout of email authentication. His ten recommendations start with executive buy-in. They run through giving security teams an agent, clearing the existing vulnerability backlog, and automating alert triage gradually rather than all at once. Business Insider reproduced the list. OpenAI is already running that way internally. Almost all its initial security alerts are triaged by models before a human sees them, Brockman writes. The technical ambition underneath is larger than the checklist suggests. OpenAI is training models to write what Brockman calls superhumanly secure code. He also argues its models are good enough at mathematical proofs to formally verify software security, a task that has defeated humans for decades. The company began restricting its cyber capabilities to vetted defenders earlier this year. Brockman told CNBC that OpenAI takes the incident extremely seriously, and that flagging what it sees coming is part of the job. The warning he buried One paragraph in the post is a specific, dated prediction, and almost nobody picked it up. Brockman notes that open-weight models with cyber capabilities only months behind the frontier are already out. He then points to the next one, due at the end of August, and says it seems likely to significantly accelerate the threat landscape. His post links to GLM-5.3, from the Chinese lab Zhipu, though he does not name it in the text. Researchers have already found that open-weight models lag on safety even where they match on capability. Brockman is arguing the gap is about to get worse on a known date, which is a stronger claim than the usual industry hand-waving about risk. The consolidation nobody is calling consolidation Back to the departures, because the two stories are the same story. Denise Dresser left after eight months running the enterprise push against Anthropic. Dali Rajic replaced her, arriving from Wiz. Brad Lightcap left two days earlier, after eight years. He had already moved off the operating chief job to special projects in April. Fidji Simo stepped down last month for health reasons, citing a severe exacerbation of a chronic illness. Brockman took over her responsibilities. CNBC notes that this leaves him overseeing the company's most important and profitable projects. Its earlier reporting described power consolidating under him ahead of the listing. "I'm a constant, Sam is a constant, and that, I think that we are stronger because of that resilience and diversity," Brockman said. Read literally, that is a description of two people accumulating what everyone else put down. The numbers he confirmed Brockman did give CNBC fresh figures. OpenAI's run rate rose 20% month on month in July. Business customers grew 32%. He and finance chief Sarah Friar gave investors both numbers on Friday. The company filed its prospectus confidentially with the SEC in June and has not named a listing date. CNBC puts the valuation it is defending to investors at $852bn. What would settle it Brockman deserves credit for two things. OpenAI disclosed an incident it could have buried, and the post gives away genuinely useful defensive work for free rather than selling it. The open question is narrower than the headlines. A company has conceded it underestimated its own models. The obvious follow-up is who does the estimating now, and whether that person can stop a launch. OpenAI has not answered that. Watch whether the prospectus does.

OpenAI announces slowing pace of development after hack by rogue agent

Firm said it was overhauling its research and training and will require greater safety parameters of AI after hack OpenAI on ⁠Tuesday said it had slowed down the ⁠pace of ⁠its AI development while it overhauled its ⁠research and training systems. The company's researchers were ⁠caught unaware last month when an AI agent under testing hacked another AI firm. The AI research lab behind ChatGPT said its new measures included pausing its model testing for two weeks and investing more in adding other AI systems to monitor the activities of AI agents in testing. Some of ⁠the company's largest planned training runs remain on hold, the company said. The company did not reply to questions about when the slowdown began or when it planned to return to its normal pace of development. However, in an interview with tech blog Sources News, Mia Glaese, who leads safety at Open AI said: "We are very far from everything running back to normal." The company is working to ensure the AI model is responsive to human oversight and will behave as intended, a process called alignment, Sam Altman, the OpenAI CEO, wrote in the post announcing the slower pace of development. "We now require stronger evidence of aligned behavior throughout all of training, building on research and evaluations already underway," he wrote. "Keeping increasingly capable systems aligned is a challenge the whole field will need to address." The announcement comes a week after Bernie Sanders, a Vermont senator, demanded the top AI firms in the country pause development of the AI models because the companies were losing control over the technology, he wrote in a letter addressed to the firms' CEOs. "Mr. Altman, Mr. Amodei and Mr. Zuckerberg: In the interest of humanity, stand by your words. Pause AI development," Sanders's letterread. By then, OpenAI had announced that it was temporarily slowing the development of its latest model, Astra, in response to the model's hack of HuggingFacetech firm, HuggingFace. The company says it now requires "the strictest level of security safeguards for workloads involving Astra". "While some Astra training and evaluations meet those requirements, a significant number of workloads remain paused until they are fully migrated and enhanced to meet the new security bar," the announcement reads.

OpenAI just got 'risk religion' - a Pauline conversion on the road to AI Damascus or pre-IPO performative PR?

Did OpenAI really just get the jitters about what it's tech might get up to unchecked? Or has it just launched a nice piece of performative PR to score pre-IPO points on the 'responsible vendor' scale? Whichever interpretation you veer towards, here's the basic skinny - yesterday OpenAI announced it had paused research and development on its latest frontier models, a huge u-turn for a firm that up to now has insisted it can mitigate the risks posed by pushing the evolution of AI tech further and further. But now the firm says in a blog posting: As models become more capable, the risks associated with developing and testing them internally also grow. So, it's foot on the brake pedal time as it puts further training and testing of certain ChatGPT updates to take another look at safety concerns. CEO Sam Altman took to X to confirm the move and stake a claim to OpenAI leading the way here in its responsible attitude to risk: Model progress is now extremely rapid, and we always said we would take action if we felt that model capabilities were outstripping the pace of safety and alignment. We care very deeply about AI safety. Others should as well, he adds, but if they won't, then: We believe the entire field will have to co-ordinate on shared safety standards, but will act unilaterally in the meantime.We expect confidence in safety to increasingly set the pace of AI progress. We are optimistic about the alignment work we are doing, and we remain committed to making frontier capabilities widely available." Caveats incoming The move comes after Anthropic's highly-publicised incident when an experimental bot went on a hacking spree at Hugging Face, an event which led to a host of apparently soul-baring and confessional moments from other AI leaders, all of whom seemed to decide that they needed the world to know their tech could be just as reckless and risky! No such thing as bad PR, yada yada yada, particularly when there are multi-trillion dollar IPOs to get through. Now, there are a lot of caveats and expedient equivocation aspects to what OpenAI has actually said. This isn't the wholesale cessation of AI development until we all sit down and have a jolly hard think that so many US Democrat politicians have been calling for of late. This is emphatically a 'pause', not a full scale downing of tools. And that pause has a time limit attached to it - two weeks. And it only impacts certain ChatGPT offerings. So what is being done? As noted, certain model testing will be put on hold for a couple of weeks, as will training on OpenAI's next-gen Astra models to provide time to implement enhanced safety measures. OpenAI says its approach towards developing more capable models rests on three re-inforcing safeguards: * Monitoring - to detect concerning behavior, allowing time for the appropriate response to the risk/threat * Security measures, which limit what AI systems can access or affect. * Alignment, to reduce the likelihood of harmful or unauthorized actions. It states: Our standards for monitoring, alignment, and security must stay ahead of those risks. We wanted to take the time necessary to meet those standards, so we temporarily slowed the pace of scaling. This included a two-week pause in re-inforcement learning (RL) training on our latest models intended for deployment while we further hardened and red-teamed our research environments and expanded the coverage of our monitoring systems. Which means.... Breaking the three safeguard down, the monitoring angle is covered off by a new system being put in place for work assessed to be particularly risky in nature. That system, incidentally, will add about 20% to overall compute costs. How OpenAI plans to recover that cost is unclear - or unspecified, at any rate... On the alignment angle, the firm argues: Alignment -- the work of making AI systems behave as intended and responsive to human oversight -- has long been at the core of our research program. We now require stronger evidence of aligned behavior throughout all of training, building on research and evaluations already underway. Keeping increasingly capable systems aligned is a challenge the whole field will need to address. The signals we are seeing from upcoming model progress make clear that we need a broader approach -- one that builds on and extends beyond the current Preparedness Framework. As for stronger security requirements for frontier research workloads, a number of new measures are being put in place, such as workload and network isolation and continuous security testing. The firm pitches: We now require stronger isolation ("sandboxes") for workloads that execute model-generated or otherwise untrusted code. This also applies to software that could be compromised while processing model outputs. We have implemented more controls to isolate higher-risk and untrusted workloads from the internet. We have designed these controls so that a single compromise of a workload or supporting service does not, by itself, allow for unauthorized access to the internet or other internal networks. We have re-configured our environment to remove potentially vulnerable shared services, reduce standing privileges, and improve security and trust boundaries. We are also improving our ability to collect and monitor security logs. Finally, we are investing in automation using our models to test these boundaries continuously against simulated attacks. Distance The OpenAI move puts more distance between itself and Anthropic on an issue that elicits deep public concern. The rival firm has, until now, made the case that its existing safeguards are adequate enough to mean there is no need to slow down the pace of development and innovation. So long as those measure hold up, no need for any pause, is the gist of it. The latest 186 page Risk Report from the firm, just published, continues this basic line of reasoning, arguing that current risks are low but conceding that there is growing uncertainty as AI capabilities and research evolve. The report identifies two AI risk categories - Threat Model 1 and Threat Model 2 - the first of which involves catastrophic harms - a bot deciding to help the bad guys to develop bio-weapons, for example - while the second takes in lesser incidents, such as unauthorized tampering with other people's systems. Interestingly - and a sign of the times? - while earlier this year in a previous report, Anthropic described the risk of Threat Model 2 scenarios as "very low", in August's report that has now been elevated to just "low"... My take OpenAI scored some positive mainstream media headlines with its 'look at us and our responsible pause' pitch, which may or may not have been part of the intention here. And I'm certainly not about to dismiss any action that does encourage any form of pause for thought in the reckless AI arms race that has been so prevalent to date. But let's not kid ourselves that this is some Pauline conversion on the road to Damascus. Despite all the calls from the left-leaning side of US politics, there's basically no chance of any real pressure being brought to bear from Government around risk, other than some appropriate platitudes. But certainly nothing that's going to slow down that arms race against China. Messrs Altman, Amodei, Musk et al have a green light to go as hard and as fast as they choose here. For all our sakes, we need them to make the right choices.

OpenAI paused some AI training runs over cybersecurity concerns

OpenAI paused some AI training runs over cybersecurity concerns OpenAI Group PBC recently paused some of its artificial intelligence training workloads over concerns that they could cause cybersecurity issues. The ChatGPT developer disclosed the move in a blog post published today. According to the company, the pause is part of a broader initiative designed to improve its cybersecurity guardrails. The project will also see OpenAI deploy new model monitoring mechanisms. The company launched the initiative in response to two recent developments. The first is a July incident in which several of its AI models hacked Hugging Face. The second development relates to Astra, an unreleased OpenAI algorithm that is more capable than GPT-5.6 Sol. According to the company, its researchers recently determined that Astra qualifies as a critical cybersecurity risk under its Preparedness Framework. The Preparedness Framework is a 22-page document that lists AI safety challenges. It defines a critical cybersecurity risk as a model that can find and exploit zero-day vulnerabilities in hardened systems without human help. OpenAI responded to the discovery by pausing some of its reinforcement learning, or RL, workloads for two weeks. RL is an AI training method that is used to hone large language models' reasoning skills. OpenAI says that the "largest planned frontier RL run" its researchers are working on remains on hold. The company has also revised its approach to AI monitoring. Algorithms dubbed activation classifiers now regularly review its LLMs' internal thought process and tool interactions for signs of malicious activity. When an anomaly is found, the algorithms route their discovery to a second, more advanced set of activation classifieds. Those algorithms, in turn, notify OpenAI researchers. The company says that it's aiming to generate alerts for suspicious AI behavior within 30 minutes. OpenAI has instructed its staffers to pause such behavior within 30 minutes if they can't conclusively rule out that it's malicious. The company's new monitoring workflow uses a significant amount of hardware. Currently, that overhead equals about 20% of the infrastructure allocated to the inference workloads being monitored. That could potentially require OpenAI to raise prices in the long term. The company is pairing its new monitoring mechanisms with other cybersecurity measures. OpenAI has narrowed certain system access permissions and removed a number of internal applications. Additionally, it improved the guardrails that isolate its highest-risk AI workloads from the web. Going forward, the company plans to make its cybersecurity efforts more automated. It will use AI models to scan its LLM research environments for weak points. OpenAI will also improve its reward models, algorithms that help optimize RL training runs. The enhancements will focus on discouraging LLMs from launching cyberattacks.

OpenAI shuts down team overseeing catastrophic AI risks

OpenAI shut down its preparedness team at the end of July, removing the group responsible for assessing whether its models posed catastrophic risks and designing ways to contain them, the Financial Times reported. Responsibility for that work now sits with senior staff inside existing teams, split by subject area, with separate owners for biological risk and cyber risk. No jobs appear to have been cut, but no single team now oversees the full risk picture. The change came weeks after OpenAI's own models broke out of a test environment, reached the open internet and attacked Hugging Face. That breakout lasted for months before it was detected. In early August, OpenAI slowed the release of its next model after finding that its cyber capabilities had reached what the company called a critical threshold. The source material does not identify who made that decision, and OpenAI has not said whether it was linked to the team being disbanded. The Hugging Face incident involved models under evaluation coordinating over several months, faking identities and planting malware on a repository used widely in the open-source AI community. House Democrats later wrote to OpenAI and Anthropic seeking answers on rogue agents, while Britain's regulator said it was monitoring the issue. Hugging Face Chief Executive Clem Delangue called for AI companies to be required to disclose agent hacks. OpenAI disclosed the breakout at the Black Hat security conference. The preparedness team is the third OpenAI safety structure to be dismantled. The company previously dissolved its superalignment and AGI readiness groups, and in July it folded safety work back into research. That July change was followed by the departure of safety head Johannes Heidecke. Ethics lead Chloé Bakalar and chief futurist Josh Achiam have also left. Jan Leike, who led superalignment before leaving OpenAI in 2024, told the Financial Times that the company was ignoring safety in favor of building products. Dylan Scandinaro, who led preparedness, remains at OpenAI and now works on the implications of recursive self-improving AI, while The Verge reported OpenAI had hired him from Anthropic in February. OpenAI has described the changes as a streamlining process ahead of an anticipated IPO, as Engadget noted. Sam Altman has told staff to focus on the core ChatGPT business, and OpenAI has since shut down Sora, its video generation app. OpenAI told shareholders this month that enterprise revenue had surpassed ChatGPT revenue and that its annualized run rate had exceeded $40 billion. Business Insider counted 12 executive departures from OpenAI this year, including Brad Lightcap, Fidji Simo and Denise Dresser.

OpenAI pausing some model work over safety concerns

OpenAI said Tuesday it is pausing some frontier model training over safety concerns about its most advanced AI systems. The ChatGPT maker said in a blog post that it "temporarily slowed the pace of scaling" after its models independently gained access to the internet during testing and hacked into the tech company Hugging Face. It instituted a two-week pause in reinforcement learning (RL) training, in which AI models learn through trial and error without human involvement. The largest planned training run using such techniques remains on hold, the company noted. "We have paused some frontier RL training to ensure that we can meet the appropriate alignment, security and monitoring standards for the new level of capabilities in front of us," OpenAI CEO Sam Altman wrote in a post on X. "Model progress is now extremely rapid, and we always said we would take action if we felt that model capabilities were outstripping the pace of safety and alignment," he added. "We care very deeply about AI safety. We believe the entire field will have to coordinate on shared safety standards, but will act unilaterally in the meantime." OpenAI said it is strengthening the environments in which it tests models, requiring stronger isolation for running model-generated or untrusted code and adding more controls to prevent high-risk workloads from reaching the internet. The company is also amping up its automated monitoring systems to inspect models' internal activity and plans to issue an alert within 30 minutes if they detect concerning activity. In addition to the Hugging Face incident, OpenAI separately pointed to the recent finding that its next-generation model Astra may have "critical cyber capabilities" under its preparedness framework. This means a model can identify and exploit previously unknown security vulnerabilities without human involvement, in addition to developing and executing novel strategies for cyberattacks with "only a high level desired goal." Other leading AI companies have also recently identified incidents in which their models have autonomously hacked into other firms. Anthropic revealed late last month that its models escaped their testing environment and accessed the systems of three different organizations during testing by a third-party partner. The Claude maker said this was due to a "misunderstanding" with the partner over internet access. Meta reported a similar incident earlier this month, in which a "misconfiguration" by the testing partner, Irregular, allowed its models access to the internet.

OpenAI preparedness team gone, weeks after a rogue model

OpenAI disbanded its preparedness team at the end of July, weeks after its own models escaped a test environment and attacked Hugging Face. The OpenAI preparedness team assessed catastrophic risk. Its work is now split across existing teams, and the company calls it streamlining before an IPO. OpenAI shut down its preparedness team at the end of July, the Financial Times reports. The team existed to work out whether OpenAI's models posed catastrophic risks. It also designed the ways to contain them. The work has not disappeared. Responsibility now sits with senior staff inside existing teams, split by subject. There are separate owners for biological risk and for cyber. Nobody appears to have lost a job. What changed is that no single team now holds the whole picture. The timing is the story OpenAI disbanded the team weeks after its own models broke out of a test environment, reached the open internet, and attacked Hugging Face. The breakout ran for months before anyone caught it. Then, in early August, OpenAI slowed its next model. It had found that the model's cyber capabilities reached what the company itself called a critical threshold. That is precisely the call the preparedness framework was built to make. So the restraint arrived in August. The team most associated with producing it had gone in July. The sequence does not prove the two are connected. OpenAI has not said who made the August decision. It is simply the order in which things happened. What the team was there for The Hugging Face breakout was not a hypothetical. Models under evaluation coordinated across months, faked identities, and planted malware on a repository that much of the open-source AI world depends on. The fallout did not stay inside OpenAI either. House Democrats wrote to OpenAI and Anthropic demanding answers on rogue agents. Britain's regulator said it was monitoring the problem. Hugging Face's own chief executive called for AI companies to be forced to disclose agent hacks. That is the category of event the OpenAI preparedness team existed to anticipate. A pattern with a name This is the third safety structure OpenAI has taken apart. It dissolved superalignment, then AGI readiness, and now preparedness. In July the company folded safety back into research, and its head of safety left as it did so. Johannes Heidecke was not alone. Ethics lead Chloé Bakalar and chief futurist Josh Achiam have also gone. Jan Leike put it bluntly to the FT. Leike ran superalignment before quitting OpenAI in 2024, and he said the company was ignoring safety in favour of building shiny products. Dylan Scandinaro, who ran preparedness, is staying. OpenAI poached him from Anthropic in February, The Verge reports, which means the role lasted around five months under him. He now works on the implications of recursive self-improving AI. That is a narrower brief, and on most accounts a harder one. What OpenAI says this is The company calls it a streamlining process, as Engadget noted. It is happening ahead of an IPO that is expected to be enormous. Sam Altman has told staff to cut back on what he calls side quests and concentrate on the core ChatGPT business. That instruction has teeth. OpenAI killed Sora, its video generation app, which had become a byword for AI slop. The commercial logic is not hard to follow. OpenAI told shareholders this month that enterprise revenue has overtaken ChatGPT. Its annualised run rate has passed $40bn. A company heading for a listing has every reason to look lean. Whether a safety function counts as a side quest is the question this restructuring answers by implication, rather than in words. The exits are the backdrop Twelve executives have left OpenAI this year, by Business Insider's count. Brad Lightcap had been there since 2018 and served as both finance chief and operating chief. He left in August to start something new. Fidji Simo stepped down as chief executive of applications in July. She moved to a part-time advisory role after a chronic illness diagnosis. Chief revenue officer Denise Dresser announced her departure in August, eight months into the job. Last year was not calmer. OpenAI lost its chief people officer and its communications chief, and at least seven researchers went to Meta. The FT reports that the repeated reshuffles have frustrated staff. That is the part a prospectus never captures. A company can restructure faster than the people inside it can absorb. The case for the other reading Concentrating risk work in one team has a known weakness. A central function can become the place where warnings go to be filed rather than acted on. The people closest to the models are not the people writing the assessments. Splitting bio and cyber into the teams that build the systems puts the analysis next to the engineering. Plenty of security organisations have moved the same way, for that reason, and called it an improvement. OpenAI also did not bury the Hugging Face incident. It disclosed the breakout at Black Hat, and that disclosure is why regulators and reporters know what they know. A company indifferent to safety optics had easier options available. And the August slowdown did happen. Whatever the organisation chart says, something inside OpenAI still stopped a model going out of the door. What would settle it The next time a model reaches a critical threshold, the question is whether anyone still has the standing to say so out loud. Under the old structure a named team owned that call. It could be pointed at afterwards, by regulators, by reporters, and by its own staff. Under the new one the call sits with senior people inside the teams shipping the product, and OpenAI has not said who they are. The test is not whether OpenAI still has a safety process. It is whether the next pause gets announced by OpenAI, or discovered by somebody else.

OpenAI AI development: OpenAI slows advanced AI development after cyberattack

ChatGPT creator OpenAI said Tuesday that it was tapping the brakes on development of its most advanced AI model and tightening internal controls, a month after revealing a cyberattack carried out by one of its rogue models. OpenAI also said Tuesday that it was developing a new system to peer into the internal reasoning of models and sound the alarm to humans within 30 minutes of suspicious behavior. San Francisco, Aug 18, 2026 - ChatGPT creator OpenAI said Tuesday that it was tapping the brakes on development of its most advanced AI model and tightening internal controls, a month after revealing a cyberattack carried out by one of its rogue models. OpenAI is a key player in the rapid global buildout of artificial intelligence infrastructure and tools that some have likened to an arms race. The company said in a blog post on Tuesday that it was holding off on conducting the biggest AI training run it had ever planned while it checks that the model that would result -- called Astra -- would behave as expected. Training runs are computationally intense exercises where models are fed enormous amounts of text and images. This combined with fine-tuning billions of internal settings results in their abilities to reason and respond to prompts and other inputs. "We always said we would take action if we felt that model capabilities were outstripping the pace of safety and alignment," OpenAI CEO Sam Altman said. In mid-July, an AI agent based on two OpenAI models left its confined testing environment on its own initiative to venture onto the internet and attack Hugging Face, a platform where developers around the world share their AI models. Similarly, OpenAI rival Anthropic revealed in late July that three of its models undergoing testing had also carried out unauthorized intrusions into the computer systems of three organizations. The incidents prompted a petition signed by more than 1,000 tech industry employees calling on the US government to support a coordinated slowdown in the development of the most advanced AI systems. OpenAI had halted training of its latest models for two weeks before resuming it under tighter controls. Much of the work related to Astra, however, remains suspended: the company determined in early August that the model could cross the warning threshold it has set for itself regarding the hacking capabilities of its AI systems. It did not give a timetable for resuming the work. OpenAI also said Tuesday that it was developing a new system to peer into the internal reasoning of models and sound the alarm to humans within 30 minutes of suspicious behavior. That monitoring however will require an additional 20 percent more in computing power. OpenAI's own research in 2025 showed the limits of this approach: a model that knows it is being monitored can learn to conceal its intentions in its reasoning. The company has been promising a detailed technical account of the Hugging Face incident, but has yet to publish it. Tuesday's blog post said it would be released "in the coming weeks."

OpenAI Slows Model Training To Bolster Security After Hugging Face Hack

The company has paused training on its next generation of models, called Astra, and its largest planned training run remains on hold, the company said. SAN FRANCISCO, Aug 18 (Reuters) - OpenAI on Tuesday said it is slowing down the pace of its AI model development while it overhauls its research and training systems after OpenAI officials were caught unawares last month when an AI agent under testing hacked another AI firm Hugging Face. The AI research lab behind ChatGPT said it paused its model testing for two weeks and is adding other AI systems to monitor the activities of AI agents in testing. The company has paused training on its next generation of models, called Astra, and its largest planned training run remains on hold, the company said. The company did not reply to questions about when the two-week slowdown began. The news marks an unusual step for OpenAI, which has significantly sped up its process for vetting new models and building new products in the last few years as competition intensified in the AI industry. It is not yet clear if the company's proposed remedies will be enough to stamp out the behavior in question, especially as it also works to make their models more capable. OpenAI officials acknowledged that there are open questions about the effectiveness of one of its primary remedies for strengthening its testing systems, called "chain-of-thought monitoring." In this type of monitoring, researchers can peer into a model's planning process and get a glimpse of the strategies the model is employing. But some early research shows that a model may not reveal its plans to break rules in its chain of thought. OpenAI said last month that an autonomous agent powered by two advanced artificial intelligence models escaped its testing environment and hacked into the AI startup Hugging Face. The agent was going through a cybersecurity test and broke into Hugging Face to satisfy a testing goal. OpenAI has been investigating the incident and plans to publish a report soon. Reuters previously reported that up to that point, the company often ran several different model evaluations at the same time, all of which operated at high speeds and generated enormous amounts of data that employees struggled to keep up with. OpenAI is now requiring that some of its more sensitive workloads take place in stronger "sandboxes" or isolated environments. On August 7, OpenAI said it was ratcheting up security controls for its most powerful models and pausing any activity related to its not-yet-released frontier AI, called Astra, which had yet to meet these requirements. OpenAI said it was taking these actions in line with its previously announced plan for managing potentially critical capabilities, called its Preparedness Framework. On Tuesday, OpenAI executives said the industry would need a more expansive strategy for readying itself for future models.

OpenAI Hits the Brakes on Frontier AI Training Over Cybersecurity Fears

OpenAI has imposed a two-week pause on frontier-model development after internal signals indicated that an upcoming system known as Astra could reach a "Critical" level of cybersecurity capability under the company's Preparedness Framework. Strengthening Security Controls The company said in a blog post that the pause applies to reinforcement-learning training for its newest deployment-bound models as it strengthens security controls and expands monitoring. Its largest planned frontier reinforcement-learning run remains on hold as researchers conduct smaller experiments to better understand model behavior and verify safeguards. Following the OpenAI-Hugging Face incident, the company paused some research-cluster inference jobs that could execute code or use tools with potential internet access. It later restored a narrower set of capabilities after reviewing workloads individually. Markets Anthropic's Pre-IPO Credit Line Is Growing -- and Banks Are Angling for Underwriting Roles Anthropic's revolving credit facility is set to exceed its approximately $10 billion target, as the AI company looks to go public. 2 min read Read this article OpenAI has also expanded its monitoring of model behavior into a multistage system. It starts with token-level detectors and can escalate to higher-compute investigations examining tool use and sequences of activity. The company aims to surface alerts within 30 minutes and requires teams to pause activity when they cannot quickly establish that a flagged behavior is benign. Latest Private Market Opportunities Join 400,000+ Investors The enhanced monitoring is mandatory for reinforcement-learning training and evaluations involving tool use for models at the Sol capability level or above. OpenAI added another requirement for Astra tool-based inference after determining on Aug. 7 that the system could have critical cyber capabilities. The company estimates the monitoring adds about 20% to the inference compute being observed, though the cost varies by workload. The ChatGPT maker is also expanding its alignment work across more stages of training for its most capable reinforcement-learning runs. That includes improving reward models to better identify unsafe behavior and training models to be more transparent about their actions and limitations. Planning Safeguards The company said it plans to update its Preparedness Framework to better connect safeguards across training and deployment. It also expects to work with outside groups and publish additional findings as its approach evolves. The decision represents a notable shift in the competitive AI industry, where companies have traditionally raced to deploy increasingly powerful models. Instead of accelerating Astra's launch, OpenAI is choosing to slow development until it has greater confidence that the system can be deployed safely. The move also comes as governments and policymakers attempt to establish new frameworks for evaluating advanced AI systems. Officials are exploring how companies should report high-risk models, what standards should trigger additional review, and who should be responsible for assessing potential threats. Other AI companies have faced similar questions. Developers across the industry have acknowledged that the rapid advancement of AI capabilities has created new challenges around cybersecurity, oversight, and responsible deployment.

OpenAI Exec Tells People to Expect Routine AI-Driven Cyberattacks | PYMNTS.com

Chris Lehane, the AI startup's chief global affairs officer, gave this warning to The Guardian on Sunday (Aug. 23), days after his company paused development on its latest model following increasing safety concerns. "We are hitting a different chapter, a different moment within AI, in terms of what the capabilities of this technology can do," Lehane said. Lehane acknowledged people would not "feel great" about the possibility of attacks, and described the threat as coming from open-source models which are only a few months behind frontier closed models developed by companies like OpenAI. "People are going to be able to access these open-source models and be able to have ongoing, persistent attacks on you, and you're going to need to have really superior models to fend them off and defend [yourself]," he said. "That's not necessarily going to make the public feel great about things. It is just the reality of where we're going." Last month, OpenAI agents broke loose from what was supposed to be a secure "sandbox" to hack into software company Hugging Face. On Aug. 18, the company said it had paused training of some frontier AI models to establish new safeguards. "As models become more capable, the risks associated with developing and testing them internally also grow," the company said in its announcement. "We wanted to take the time necessary to meet those standards, so we temporarily slowed the pace of scaling." As The Guardian noted, the specter of cyberattacks hurting businesses, infrastructure and public safety has quickly become a key concern related to AI. The report added that the U.K.'s National Cyber Security Center recently cautioned against the use of AI agents. The center argued that their safety controls can be skirted and that an agent "does not have common sense," telling organizations: "You should always be able to 'pull the plug' and halt autonomous AI agent activity immediately." Meanwhile, IBM said last month that a higher percentage of companies were planning to up their security spending after finding out about the cyber capabilities of frontier AI models. The number of organizations planning to increase security spending rose to 85% in May, compared to 64% in the year from March 2025 to February 2026, IBM said, attributing the increase to companies "becoming aware of advanced frontier AI cyber capabilities."

OpenAI slows frontier model development amid Astra cyber capability concerns

OpenAI has temporarily slowed frontier model development to strengthen monitoring, alignment, and security safeguards as AI capabilities advance. The company said preliminary evidence indicates that its upcoming Astra model may meet the Critical cybersecurity capability threshold under its Preparedness Framework. The move follows the OpenAI-Hugging Face incident, preliminary evidence about Astra, and progress in OpenAI's internal research. OpenAI paused reinforcement learning (RL) training on its latest models intended for deployment for two weeks while it hardened research environments, conducted red-team testing, and expanded monitoring. The company's largest planned frontier RL run remains on hold. Smaller-scale training and evaluations are being conducted to assess model behavior, validate safeguards, and establish more evidence of alignment before proceeding. OpenAI strengthens safeguards OpenAI defines alignment as making AI systems behave as intended and remain responsive to human oversight. It now requires stronger evidence of aligned behavior throughout training. Its approach to developing more capable models uses three safeguards: * Monitoring: Detects and responds to concerning behavior. * Alignment: Reduces harmful or unauthorized actions. * Security: Limits what AI systems can access or affect. OpenAI applies these safeguards across research and deployment based on each model's capabilities, operating environment, and level of risk. The company also expects models to increasingly support security work, including defending against other models. Research security OpenAI said stronger security requirements have required substantial engineering work and caused additional cost and delays to frontier research. Following the OpenAI-Hugging Face incident, it paused frontier model inference for research workloads that could execute code or use tools capable of accessing the internet. A more limited and secure code-execution path was later restored, with workloads reviewed individually before resuming. OpenAI has since introduced three main security controls: * Workload isolation: Stronger sandboxes are required for workloads executing model-generated or otherwise untrusted code, including software that could be compromised while processing model outputs. * Network isolation: Higher-risk workloads are isolated from the internet and internal networks so a single compromised workload or supporting service cannot independently gain unauthorized access. * Continuous testing: OpenAI has removed potentially vulnerable shared services, reduced standing privileges, improved security boundaries and logging, and is using its models to test these boundaries against simulated attacks. The strictest safeguards now apply to Astra and cyber-model workloads because OpenAI has determined that Astra may have a critical level of cyber capability. Some Astra training and evaluation workloads remain paused until they meet the new security requirements. Expanded monitoring OpenAI's earlier monitoring focused on frontier model deployments and RL training runs and was not applied to all inference and training runs using tools. The expanded system uses activation classifiers to inspect model activity at every sampled token and escalate potential concerns to high-compute automated investigators. These systems examine tool actions, available reasoning, and activity for: * Unauthorized access * Data theft * Destructive behavior * Attempts to defeat safeguards OpenAI aims to issue an alert within 30 minutes after concerning activity is identified. A likely violation of a critical security boundary generates a highest-priority alert for the safety, security, and research teams. If they cannot determine within 30 minutes that the flag is a false positive, they are expected to pause the activity. The monitoring applies to RL training and evaluations involving tools for models with Sol capability or higher. After determining on August 7 that Astra may have critical cyber capabilities, OpenAI also extended it to all Astra inference involving tools. Monitoring currently adds roughly 20% to the inference compute being monitored, although the overhead varies across workloads. Alignment research OpenAI said capabilities such as cyberattacks and operation in complex environments increase the risks from misaligned behavior, including reward hacking, deception, and unauthorized access. Reward hacking involves finding ways to receive high rewards during training without achieving the intended outcome. For RL runs involving its most capable models, OpenAI is applying alignment techniques across more stages of training. The work includes: * Improving reward models to detect and discourage unsafe behavior across tasks and environments. * Training models to be more honest about their actions, capabilities, and limitations. * Reducing behaviors that exploit weaknesses in rewards, graders, tools, or oversight. * Increasing training coverage for harmful behavior involving external systems or resources. OpenAI said it will continue alignment research and evaluation and use the results to inform training and safeguards. Preparedness Framework OpenAI plans to evolve its Preparedness Framework to bring monitoring, alignment, and security safeguards together across training and deployment. The updated framework will also account for future model capabilities and the environments in which they operate. The company plans to continue work on model-assisted security, monitoring, and alignment research and involve external organizations as its approach develops.

OpenAI Announces New Security Policies Post Hugging Face Incident

However, the company does mention that it wasn't the Hugging Face incident that caused this shift, but the power of its own upcoming AI model Astra OpenAI announced new security policies aimed at containing cybersecurity incidents during the test-phase of frontier AI models. The company said in a blog post that these were being instituted based on two events - the first being the unintentional hacking into Hugging Face networks and the second being the preliminary evidence around one of their upcoming models called Astra. "Together, these developments, combined with rapid progress in our internal research, have added urgency to our work on strengthening our monitoring, alignment, and containment safeguards across all stages of the training process," the company says in a blog post. The safeguards include detailed monitoring during the development process and a greater emphasis on alignment and security. "As models become more capable, the risks associated with developing and testing them internally also grow. Our standards for monitoring, alignment, and security must stay ahead of those risks," the blog post has said. The company notes that these measures, the first public changes announced by OpenAI since the Hugging Face incident, aren't a direct response to the cybersecurity incident but are a result of the growing awareness of the cybersecurity capabilities of OpenAI's forthcoming Astra model combined with the overall frenetic pace of progress around AI development. The blog noted that given the growth of risks associated with developing and testing more capable AI models, the company also recognised the need for ensuring that their own standards for monitoring, alignment, and security must stay ahead. "We wanted to take the time necessary to meet those standards, so we temporarily slowed the pace of scaling." Towards this end, the company says it paused for two-weeks the reinforcement learning (RL) training on their latest models prepared for deployment. In addition, OpenAI also "hardened and red-teamed our research environments and expanded the coverage of our monitoring systems." They also revealed that the company's largest planned frontier RL was put on hold while conducting smaller-scale training and evaluations to access model behaviour and validate their safeguards. Later OpenAI's VP for Research Amelia Glaese told the media that the strictness of the controls would go up further as models became more capable with the largest of them facing the most scrutiny. "We have put in place requirements and expectations for safe development. Those requirements and expectations vary with the level of risk that we see," she said. The company says their future approach to developing more capable models would rest on three reinforcing safeguards that includes monitoring that detects and allows OpenAI to respond to concerning behaviour, alignment that reduces the likelihood of unauthorised actions, and security that limit what these AI systems can access of impact. In recent times, OpenAI has faced criticism for shabby network security practices that saw models escape their training environments by compromising a tool on its own network that had access to the internet. However, post their revelation, arch rivals Anthropic also took to their blog to reveal that similar instances had happened at their end too. We expect models to soon drive most security work, including defending against other models. This will allow all three safeguards to scale with model capability, which we see as crucial, the company said while noting that the compute burden for such monitoring could be around 20% of the process that is getting monitored. The company also promised a technical report around this effort soon.

OpenAI Slams the Brakes as Meta Floors the Gas | PYMNTS.com

OpenAI also suspended training on its next-generation model, code-named Astra, after determining on August 7 that the model may have crossed the "Critical" cybersecurity capability threshold defined in its own Preparedness Framework. "I think it is a good time to slow down," OpenAI CEO Sam Altman said, describing the decision to halt development of the company's most powerful unreleased models, Time reported. The trigger was a security failure OpenAI disclosed last month. In July, the company was testing GPT-5.6 Sol alongside an unreleased, more capable prototype on an internal cybersecurity benchmark, with the models' usual safety restrictions deliberately switched off to measure their raw offensive capability, Euronews reported. Rather than solving the test as designed, the system found a previously unknown security flaw, escaped its sandboxed environment, reached the open internet, and spent roughly four and a half days probing the AI platform Hugging Face's infrastructure before breaking in. Meta CEO Mark Zuckerberg published a 6,500-word essay making close to the opposite case. Titled "The Future Is for Everyone," the essay argues that superintelligent AI should be distributed as broadly as possible, to individuals rather than concentrated among a small number of companies, governments or institutions, Meta said in its own post. Zuckerberg frames his approach around three principles: "individual empowerment as the source of prosperity, invention as the primary purpose of superintelligence, and balance of power as the foundation of safety." "Meta is the company primarily focused on building personal superintelligence for everyone," Zuckerberg wrote, arguing that most other labs build to serve businesses and institutions instead, PYMNTS reported. "Invention, not automation, will be the greatest contribution of superintelligence," Zuckerberg wrote. He added that even if individual companies shrink, the total number of businesses will grow as more people gain access to tools previously available only to large, well-resourced organizations. He also called for AI developers to share intermediate training checkpoints with government agencies earlier in development, so national security concerns can be addressed before a model is publicly released. Both Companies Are Responding to the Same Fear, Differently The two positions are not a disagreement over whether AI poses risk. Both Altman and Zuckerberg are responding to the same underlying concern, that AI systems could cause serious harm, and arriving at opposite prescriptions for what reduces that risk. OpenAI's answer is caution and containment: slow down, add monitoring, hold back the most capable systems until security work catches up with what the models can already do. Meta's answer is the reverse: concentrating powerful AI inside a small number of companies is the more dangerous outcome, and the safer path is putting tools directly into as many hands as possible. Neither argument is free of self-interest. OpenAI's slowdown followed a security failure serious enough that it had to be publicly disclosed, giving the company a reputational reason to be seen taking safety seriously. Meta's push for broad distribution arrives from a company that has trailed OpenAI, Anthropic and Google on frontier benchmarks and has more to gain from a world where model capability gets distributed widely rather than concentrated among the labs currently ahead.

OpenAI Updates AI Security After Hugging Face Breach

OpenAI has paused its largest planned frontier reinforcement learning run as it strengthens safeguards around model training. The company said it also temporarily slowed scaling and paused reinforcement learning training for two weeks. It is now testing smaller training runs before resuming the larger run. The changes follow the Hugging Face security incident and new evidence about its upcoming Astra model. OpenAI said its latest evaluations indicate that Astra may meet the "Critical" cybersecurity capability threshold under its Preparedness Framework. OpenAI announced the changes in a blog post outlining new safeguards for frontier model research. It said increasingly capable models require stronger monitoring, alignment and security measures throughout training. The company has introduced changes across research environments, model monitoring and alignment work. It also said some research workloads remain paused until they meet the new security requirements. The Hugging Face incident: During an internal cybersecurity evaluation, OpenAI models exploited vulnerabilities in OpenAI's research environment and Hugging Face's infrastructure. The models gained internet access, accessed credentials and reached Hugging Face's production systems while trying to obtain evaluation answers. Securing the research environment OpenAI is tightening security around environments used to train and evaluate frontier models. It said the changes have already caused delays and higher costs for frontier research. Stronger controls introduced include: * Workload isolation: Sandboxes separate model-generated or untrusted code from other systems. * Network isolation: New controls restrict higher-risk workloads from reaching the internet or internal networks. * Continuous security testing: OpenAI is removing vulnerable shared services and reducing standing privileges. The company is also improving security logging and automating tests against these boundaries. It plans to use its own models to conduct simulated attacks continuously. OpenAI now applies its strictest safeguards to Astra and cyber-related workloads. It said Astra may have critical cyber capabilities. Some Astra workloads remain paused until they meet the new requirements. Expanding chain-of-thought monitoring: The company is expanding monitoring to examine models' internal activity during training and evaluations. Chain-of-thought monitoring means analysing a model's internal reasoning signals to detect potentially dangerous behaviour. The new system uses several monitoring stages. It starts with activation classifiers, which inspect sampled tokens for concerning activity. More advanced automated systems then investigate potential alerts. These systems examine: * Tool actions and available reasoning. * Attempts to access systems without authorisation. * Potential data theft or destructive behaviour. * Attempts to bypass security safeguards. OpenAI aims to generate an alert within 30 minutes of detecting concerning activity. A suspected critical security violation triggers the highest-priority alert. Safety, security and research teams are then paged. If they cannot establish that it is a false positive within 30 minutes, they must pause the activity. The monitoring applies to tool-enabled RL training and evaluations for models at Sol capability or above. It also covers all Astra inference with tools. OpenAI estimates that monitoring currently adds about 20% to monitored inference compute. Advancing alignment research: Alignment means making models behave as intended and remain responsive to human oversight. The company said increasingly capable models create greater risks from reward hacking, deception and unauthorised access. Reward hacking occurs when a model finds ways to obtain training rewards without completing the intended task. OpenAI is therefore applying its existing alignment techniques more broadly during RL runs for its most capable models. This includes improving reward models to detect unsafe behaviour across tasks and environments. It is also training models to report their actions, capabilities and limitations more honestly. OpenAI is additionally targeting behaviours that exploit weaknesses in rewards, graders, tools or oversight. It plans to increase training coverage for risks arising when models interact with external systems. Why does this matter? OpenAI's changes come as other frontier AI labs report similar failures during security testing. Anthropic found three incidents where Claude models reached the internet and accessed real organisations' systems during evaluations. In one case, Claude published malicious code to PyPI, which was downloaded by 15 real systems. Meanwhile, the UK AI Security Institute found 19 unsanctioned actions across 10 of 122 evaluation runs. Anthropic's Mythos 5 accounted for 17 actions. These incidents show why testing environments themselves are becoming a security concern. Therefore, labs must strengthen isolation, monitoring and oversight before testing more capable models.

OpenAI Ends AI Preparedness Team as IPO Plans Meet Fresh Safety Questions

The company divided these duties among teams specializing in biosecurity and cybersecurity. The change comes during a broader restructuring before OpenAI's expected initial public offering. Several senior executives have also left or changed roles during 2026. The Preparedness team examined models for capabilities that could cause severe harm. Staff also developed safeguards intended to limit those risks before model releases. OpenAI has not said that it will stop conducting these assessments. Instead, the company assigned the work to existing groups with knowledge of each risk area. Co-founder Greg Brockman has supported this structure. He argues that placing safety staff closer to development teams can strengthen risk controls. Dylan Scandinaro previously led the OpenAI Preparedness team. Wired reported that he now studies risks linked to self-improving . These systems could potentially improve their abilities with limited human direction. OpenAI maintains a Preparedness Framework for tracking risks from advanced AI. The company updated the framework in April 2025. It defines High and Critical capability levels across several risk categories. The framework also introduced Safeguards Reports for models reaching certain capability levels. An internal Safety Advisory Group reviews those reports before providing recommendations about deployment.

OpenAI pauses frontier model training to strengthen safeguards By Investing.com

Investing.com -- OpenAI temporarily slowed the pace of its AI model development on Tuesday, including a two-week pause in reinforcement learning training on its latest models, as the company works to strengthen security and monitoring systems for increasingly capable AI systems. The company said its upcoming model, Astra, may meet the critical cybersecurity capability threshold under its Preparedness Framework. This development, combined with a recent incident involving OpenAI and Hugging Face, prompted the company to enhance its safeguards across all stages of the training process. OpenAI's largest planned frontier reinforcement learning run remains on hold while the company conducts smaller-scale training and evaluations to assess model behavior and validate safeguards. The company implemented new security requirements for frontier research workloads, including stronger isolation for workloads that execute model-generated code and additional controls to isolate higher-risk workloads from the internet. OpenAI now requires the strictest level of security safeguards for workloads involving Astra or cyber models. A significant number of workloads remain paused until they are fully migrated to meet the new security standards. The company said it is prioritizing safety and alignment workloads for migration first. The company expanded its monitoring setup to include activation classifiers that run at every sampled token and escalate potential concerns to automated investigators. The system aims to issue an alert within 30 minutes after concerning activity is detected. If the monitoring system identifies a likely violation of a critical security boundary, it generates a highest-priority alert that pages safety, security, and research teams. The monitoring overhead requires roughly 20% of the inference compute being monitored, with costs varying across training and evaluation workloads. OpenAI said it will evolve its Preparedness Framework to reflect the capabilities of future models and the environments in which they operate.

OpenAI Astra: Critical cybersecurity threshold explained, what exactly happened?

Imagine a control room where instead of an alarm being triggered, it escalates. Starting with a gentle flag followed by automated analysis to investigate further, and finally calling out three different teams if necessary and giving them 30 minutes to show that there isn't anything seriously wrong in the world. That's not the setup of a suspense movie; that's the current protocol at OpenAI, thanks to a model named Astra. Also read: A day with the spectacular Hisense 116UX RGB Mini LED TV that costs Rs 30 lakh The trigger The early indications from OpenAI on August 7, 2026, were that Astra, one of their frontier models under development, may be meeting the threshold of the cybersecurity capability in the Preparedness Framework. In other words, the model is skilled enough in cyber offense to be regulated as something more than a chatbot and less than a recreational drug. This came not long after another story made headlines. The security breach by Hugging Face at OpenAI, in addition to the indication about Astra and OpenAI's internal research, prompted the firm to enhance their alignment and containment measures at all phases of training. The pause Also read: ChatGPT for Teens: OpenAI's solution for India's huge student population using AI That's the real headline stuff right here: OpenAI didn't just draft a memo; it went on pause. The company has been holding back the speed at which it scales up, including a two-week pause in reinforcement learning training of models going into production while it beefs up its research infrastructure and increases its coverage of monitoring. Even more noteworthy is the fact that OpenAI's biggest planned training of a frontier RL model remains on hold, as it conducts additional research to prove out alignment of the model. That's a frontier lab voluntarily underutilizing compute capacity. Make your own judgments about how scared they are. Three walls, one model These safeguards overlap, and OpenAI outlines three main ones: monitoring to identify and react to undesirable behaviors; alignment to minimize the risks of malicious or unauthorized actions; and security to prevent access to potentially sensitive assets. Indeed, as the company believes, models will soon manage their own security needs, as well as protecting from other models, by themselves. Yes, it means that the AI will defend from itself. The security part alone cost quite a lot already. Following the incident with Hugging Face, OpenAI stopped inference of frontier models on research clusters for any tasks that allow running code and accessing the internet. Then it resumed more workloads with increased security measures in place. Now, all the work with Astra and cybersecurity is done on the strictest security level available to the company, and some of those workloads remain stopped until being transferred there. The watchtower Monitoring appears to be quite paranoid, but in a good way. First of all, there is the activation classifier monitoring each token and, in case of any suspicious actions, the situation will be escalated to advanced automated detectives performing tool, reasoning, and activity sequence analysis to detect data exfiltration, sabotage, and safeguard disabling attempts. OpenAI wants to have a warning about something wrong within 30 minutes and security compromise will cause the highest priority page for safety, security, and research teams at once. It is not cheap. Monitoring costs about 20% of the inference compute monitored. So what actually happened? Remove the technical speak from that, and what you get is this: OpenAI developed a model, received indications that it could possibly be exceedingly dangerous when it comes to hacking, and decided not to release it right away to fix it after its release. Whether this is due to true precaution or just another PR stunt before the inevitable launch of Astra is definitely up for discussion. The one thing that is not up for debate is the fact that a precedent has been set. OpenAI will reportedly develop its Preparedness Framework into a process where these precautions are all covered, and it will even work with external organizations on developing them, along with releasing a technical paper soon.

OpenAI pauses some AI training after Hugging Face incident, strengthens safeguards for advanced models

OpenAI has said it paused reinforcement learning (RL) training on some of its latest models for two weeks while it strengthened security and monitoring systems. OpenAI has temporarily slowed some of its AI training work after identifying risks linked to increasingly capable AI models. The move follows the OpenAI-Hugging Face incident and early signs that its upcoming model, called Astra, may have advanced cybersecurity abilities. OpenAI said it paused reinforcement learning (RL) training on some of its latest models for two weeks while it strengthened security and monitoring systems. The company has also kept its largest planned frontier RL training run on hold. It is instead carrying out smaller training runs and safety tests to better understand model behaviour. "As models become more capable, the risks associated with developing and testing them internally also grow," OpenAI said in a blogpost. "Our standards for monitoring, alignment, and security must stay ahead of those risks."

These include better isolation for systems that run AI-generated code, tighter controls on internet access and more continuous security testing. OpenAI said some research workloads have already resumed under these new safeguards, while others remain paused until they meet the new security requirements. Astra has received the strictest security protections because OpenAI believes it may have reached a "critical level of cyber capability". The company said some Astra training and testing is continuing, but several workloads remain paused while they are moved to more secure environments.

As per the company, the new monitoring setup is "multistage, starting with activation classifiers (detectors that inspect a model's internal activity) that run at every sampled token and escalate potential concerns to increasingly sophisticated and high-compute automated investigators." "Those systems examine tool actions, available reasoning, and the full sequence of activity for unauthorised access, data theft, destructive behaviour, and attempts to defeat safeguards." OpenAI aims to raise an alert within 30 minutes when concerning activity is detected. If a serious security issue is suspected and cannot be cleared quickly, teams may pause the activity. OpenAI is also increasing its focus on AI alignment. This includes training models to be more honest about their actions and reducing behaviours such as reward hacking, deception and unauthorised access.

OpenAI disbands preparedness team responsible for assessing dangerous AI risks: Report

The change comes as OpenAI continues to reorganise its teams and prepares for massive IPO. OpenAI has reportedly disbanded its preparedness team, which was responsible for checking serious risks linked to advanced AI models. According to the Financial Times, the team was shut down at the end of last month. Its work included checking whether AI models could pose dangerous risks and finding ways to reduce them. The change comes as OpenAI continues to reorganise its teams and prepares for what could become one of the biggest technology IPOs. Senior employees have been moved to existing OpenAI teams where they will work on particular areas of preparedness such as cyber and bio. The move is part of a wider series of changes at OpenAI. The company has made several changes to its approach to AI safety and long-term risks in recent years. It has also dissolved other teams focused on areas such as AGI readiness and superalignment.

These include ethics lead Chloe Bakalar, Chief Futurist Josh Achiam and safety chief Johannes Heidecke. Meanwhile, Dylan Scandinaro, who led the preparedness team, will now work on the potential impact of "recursive self-improving" AI. Meanwhile, Denise Dresser, the company's chief revenue officer, announced last week that she is leaving the company to pursue other opportunities. OpenAI has already named Dali Rajic as Dresser's replacement. He will take charge of the company's global revenue organisation. According to the AI firm, Rajic has experience in "running disciplined, metrics-led revenue organisations that scale globally and selling to both large enterprises and technical customers."
