Trump administration allows Anthropic to release Mythos 5 to select US organizations

Trump Administration Allows Anthropic to Release Mythos to Select US Organizations

The US government has eased the restrictions it imposed on Anthropic's most advanced AI model, Claude Mythos 5, allowing the company to grant access to more than 100 US organizations, including large corporations and government agencies. In a letter sent to Anthropic's cofounder and chief compute officer Tom Brown obtained by WIRED, Commerce Secretary Howard Lutnick told the AI lab it would permit certain trusted partners to regain access to Mythos because he had "determined that appropriate safeguards are in place." Semafor first reported on the existence of the letter. "Anthropic has worked with the U.S. government to address risks associated with the Covered Models. These efforts have yielded significant progress," Lutnick wrote. However, the White House stopped short of permitting a broader roll out of the model, and said nothing about the fate of Claude Fable 5, the consumer-facing version of Mythos that Anthropic released with significantly more safeguards. Lutnick noted in his letter that all other requirements outlined in the initial directive he sent on June 12 remain in effect. "We received notice from the US government that Mythos 5, our strongest cybersecurity model, can be redeployed to a small group of cyber defenders and infrastructure providers," Anthropic spokesperson Eduardo Maia Silva said in a statement to WIRED. "We are working to provision the approved set of providers and restore their access to Mythos 5 as quickly as possible. We are pleased to see this progress and continue to work with the government to expand access to Mythos 5 and make Fable 5 available for general use again." The partial reinstatement comes roughly two weeks after the White House sent an export control directive to Anthropic that required the company to limit foreign nationals from accessing Claude Mythos and Fable 5, including people working and living in the United States. In his latest letter, Lutnick wrote that organizations approved to use Mythos may now extend access to their foreign national employees, as well as Anthropic's foreign national employees. The Trump administration developed concerns about Anthropic's rollout of Mythos after it learned the company shared access with a South Korean telecommunications firm it believed to have ties to China, WIRED previously reported. After Amazon and the NSA raised concerns that Claude Fable 5, a safeguarded version of Mythos 5, could be jailbroken, the Trump administration became convinced it needed to take action. In recent weeks, Anthropic sent senior members from its cybersecurity and AI safety teams to Washington, DC to meet with Trump administration officials. In addition to Brown,public policy chief Sarah Heck has also been leading the company's discussions with the US Department of Commerce. Getting Mythos 5 back online marks a promising step forward for Anthropic and the White House, but the entire saga has raised broader questions about the overall direction of US AI policy, particularly the extent to which the Trump administration will seek to control future model releases. On Friday, OpenAI announced it was delaying the release of its upcoming GPT 5.6 models, in response to a request from the Trump administration. Dean Ball, head of the strategic futures team at OpenAI and a former White House AI adviser, said in a June 16 blog post that Anthropic's latest spat with the Trump administration has shown frontier AI model developers they "need an explicit green light from the government now." Anthropic's battles with the White House have been costly for the young company's business. It sued the Trump administration earlier this year over a supply chain risk designation it received after trying to set redlines around how military contractors could use its AI models. WIRED previously reported that some Anthropic investors worked over last weekend to determine what the White House's restrictions on Claude Fable 5 meant for Anthropic's corporate future.

Anthropic's Mythos 5 is back

After a rollercoaster negotiation process with the Trump administration that dragged on for two weeks, Anthropic's Mythos 5 is finally back in action -- at least, somewhat, for a select group of organizations, according to a letter from the government to Anthropic that was viewed by The Verge. Fable 5, however -- the public-facing Mythos-class model -- appears to still be in limbo, with no apparent timeline for a rollout agreement. The letter, dated June 26th and sent by Commerce Secretary Howard Lutnick to Anthropic co-founder Tom Brown, who had been recently leading negotiations, states that there's been a "revision to the license requirements" based on the fact that Anthropic has recently "worked with the U.S. government to address risks" associated with Mythos 5 and Fable 5. Anthropic spokesperson Danielle Ghiglieri told The Verge in a statement that the company had "received notice from the US government that Mythos 5, our strongest cybersecurity model, can be redeployed to a small group of cyber defenders and infrastructure providers." She added, "We are working to provision the approved set of providers and restore their access to Mythos 5 as quickly as possible. We are pleased to see this progress and continue to work with the government to expand access to Mythos 5 and make Fable 5 available for general use again." The US government did not lift the export control directive it hit Anthropic with two weeks ago, which barred any foreign national from accessing either model (including Anthropic's own employees). Instead, the government essentially made an exception for Mythos 5, approving a select group of organizations for access the same way it did for OpenAI's GPT-5.6, announced earlier today. Under this exception, Anthropic employees who aren't US nationals and members of the approved organizations who aren't US nationals are all greenlit to access Mythos 5, according to the letter. "These efforts have yielded significant progress," Lutnick wrote. "In addition, Anthropic has committed to work with the U.S. government on protocols and standards and releases for [Mythos-class models]. In light of this progress ... I have determined that appropriate safeguards are in place to permit certain trusted partners to access the Claude Mythos 5 Model." Pressure has been building on the Trump administration to make a change in the case-by-case type of regulatory environment it recently adopted, especially as Anthropic's competitors' cybersecurity-focused models kept getting better and better -- and even pulling ahead of it on some cybersecurity-focused benchmarks. Pressure was also building within the US AI industry, particularly fears about the AI advancements China could make while top US AI labs were sidelined. Plus, there was the fact that top US government departments, like the National Security Agency, had lost access to Mythos 5. Now, Anthropic has essentially the same deal OpenAI has: Release the model in a limited preview setting, for approved organizations only, such as trusted enterprises and the US government itself. Both AI labs hope that more general availability comes soon, both for enterprise deals and for public access (like with Anthropic's Fable 5), but it'll be ultimately up to the Trump administration. Though many have called for AI regulation, including AI labs themselves, a current consensus among some tech leaders is that the past two weeks haven't been the way to do it. In fact, OpenAI wrote in the company's GPT-5.6 blog post, "We don't believe this kind of government access process should become the long-term default. It keeps the best tools from users, developers, enterprises, cyber defenders, and global partners who need them. We are taking this short-term step because we believe it is the strongest path to broader availability in the coming weeks, while we work with the Administration to develop the cyber Executive Order framework and a repeatable process for future model releases." Lutnick wrote in his letter to Anthropic, "All other requirements of the June 12 letter remain in effect until further notice." He added, "I reserve the right to reevaluate and adjust the scope of license requirements on [Mythos 5 and Fable 5], should circumstances change."

US allows Anthropic to release Mythos to some US companies

June 26 (Reuters) - The U.S. government on Friday allowed Anthropic to release its powerful Claude Mythos 5 AI model to some "trusted partners", according to a Commerce Department letter seen by Reuters. More than 100 companies and institutions have ⁠access to Mythos 5, including many Fortune 500 companies, a source told Reuters. "Since the issuance of my June 12 letter, Anthropic has worked with the U.S. government to address risks associated with ⁠the Covered Models," U.S. Commerce Secretary Howard Lutnick said in the letter to Anthropic. "In just two ⁠weeks, we have worked diligently to ensure America remains the global leader ⁠and AI while safeguarding our security," a Commerce Department ⁠spokesperson said.

Trump administration allows some access to Anthropic's Mythos

The US government has allowed Anthropic to release its newest model to a small group of partners, easing tensions between the Trump administration and the company amid rising industry unease about Washington's approach to regulating AI. The commerce department gave Anthropic the green light on Friday to put its most advanced model, Mythos 5, back into the hands of 100 or so "trusted partners", including companies and US government departments, according to people with direct knowledge of the matter. The partial release came after Anthropic made progress towards addressing security risks posed by its advanced AI model, the people said. The commerce department said: "In just two weeks, we have worked diligently to ensure America remains the global leader in AI while safeguarding our security." But the model, as well as a rival product OpenAI released on Friday, will not be distributed more widely for now. Instead, the government has asked to vet and approve users, in effect controlling who can and cannot access the technology. It was "bad news" that OpenAI's model would not be more widely available, the group's chief executive Sam Altman said in a social media post on Friday. Altman said providing trusted partners with models first was "reasonable", but added "this isn't quite the process that we think is optimal". The White House has set out plans for a voluntary framework to ensure new models are safe before release but is yet to implement an official process, instead intervening on an ad hoc basis to contain AI risks. The government hit Anthropic with an export control two weeks ago, prompting the AI lab to withdraw its latest models. That export control remains in place, meaning most businesses will not see access reinstated. A publicly accessible version of the model, Fable 5, will not be released at this stage, the people said. Prominent investors and technologists have warned the government's approach risks stymieing US development and gives an advantage to adversaries including China. Venture capitalist Marc Andreessen in an interview on Thursday said: "We're in a weird state of the world where the supposedly totalitarian regime is trying to open up the technology, and the supposedly democratic governance system is trying to restrict and control technology." Andreessen has backed multiple AI groups including OpenAI and is an influential figure in Washington. Dean Ball, a former senior AI adviser to President Donald Trump who will join OpenAI next month, wrote that the administration had created a "de facto involuntary licensing/preapproval regime for frontier models". "The administration itself does not seem to know what safety standards or best practices a company would have to observe for them to be comfortable with the broad release of a model that matches or exceeds Mythos in capability," he added. Anthropic said it was working to restore access to a "small group of cyber defenders and infrastructure providers" as quickly as possible. "We are pleased to see this progress and continue to work with the government to expand access to Mythos 5 and make Fable 5 available for general use again."

Trump admin allows Anthropic to release Mythos AI model to some companies, government agencies: Reports

The U.S. government on Friday granted Anthropic permission to release its Mythos 5 model to a group of roughly 100 companies and federal agencies, according to multiple media reports. The decision marks a major step forward in the negotiations between the Trump administration and the artificial intelligence company, which have been engaged in a two-week-long standoff over its latest models. Anthropic said earlier this month that it disabled access to its Fable 5 and Mythos 5 models to comply with an export control directive from the government that cited "national security authorities." The company said it was instructed to suspend all access "by any foreign national, whether inside or outside the United States, including foreign national Anthropic employees." Senior Anthropic staffers flew to Washington D.C. to meet with members of the Trump administration to try to find a way to bring the models back online. The company told CNBC earlier this month that both parties were "working quickly to get this resolved."

U.S. Loosens Restrictions on Anthropic's Mythos A.I. Model

Anthropic and the Trump administration reached a deal on Friday to bring one of the company's most powerful artificial intelligence models back online, after days of tense negotiations. In a letter sent to Anthropic, the Commerce Department gave the San Francisco company permission to restore some clients' access to its Mythos 5 model, which the government restricted two weeks ago because of national security concerns. Talks were still underway to restore access to another powerful Anthropic model, Fable 5, and to provide Mythos to more organizations, said a person familiar with the talks, who spoke on the condition of anonymity because the person was not allowed to discuss them publicly. "Anthropic has worked with the U.S. government to address risks associated with the covered models," said the letter, which Commerce Secretary Howard Lutnick sent to Anthropic on Friday. "These efforts have yielded significant progress." Mr. Lutnick added that Anthropic had committed to working with the U.S. government on protocols for future releases of A.I. models. What you should know about anonymous sources. The Times makes a careful decision any time it shields the identity of a source. The information the source supplies must be newsworthy, credible and give readers genuine insight. Learn more about our process. The letter was reported earlier by Semafor. The deal de-escalates the feud between the Trump administration and Anthropic, one of the most influential A.I. companies. But it may do little to ease concerns that the administration is intent on taking a more active role in the release of new A.I. systems. Under the deal, Anthropic agreed to place safeguards on its A.I. models in exchange for restoring access to hundreds of clients. The Commerce Department had abruptly told the company on June 12 that it had 90 minutes to disable Mythos and Fable. Anthropic later discovered that the administration's concerns stemmed from a paper published by Amazon researchers that pointed to a perceived security shortcoming. The researchers were able to persuade the A.I. model to disclose flaws in bits of vulnerable software code. Amazon did not include tests of models from other A.I. firms, some of which are capable of generating the same information, cybersecurity experts who had seen or been briefed on the report said. Despite easing its restrictions on Anthropic, the administration's interest in managing the release of A.I. models appears to be expanding. Earlier on Friday, OpenAI, Anthropic's main rival, unveiled an A.I. technology called GPT-5.6 Sol, saying it matched the performance of Mythos on standard benchmark tests used by A.I. companies. OpenAI said it would initially share the technology with only a small number of companies approved by the administration. "We don't believe this kind of government access process should become the long-term default," the company said in a blog post. "It keeps the best tools from users, developers, enterprises, cyber defenders, and global partners who need them. We are taking this short-term step because we believe it is the strongest path to broader availability." (The New York Times has sued OpenAI and Microsoft, claiming copyright infringement of news content related to A.I. systems. The two companies have denied those claims.) The administration also pressed Meta this week to submit its A.I. models for voluntary review. Meta is the only major U.S. developer of A.I. technology that has not reached an agreement to voluntarily share its models with the federal government for review. OpenAI, Anthropic, Google, xAI and Microsoft all agreed to submit their models to the government's A.I. safety group, known as the Center for A.I. Standards and Innovation. Overseen by Mr. Lutnick, the center was created by the Biden administration to vet A.I. models and has a technical staff to lead those evaluations. Cade Metz, Tripp Mickle and Tyler Pager contributed reporting.

Anthropic's Mythos is coming back for a select group of entities approved by the U.S. government

Why it matters: The abrupt removal of Mythos 5 and Fable 5 created uncertainty within the industry and among allies around the world whose cyber capabilities were stunted by the loss. Inside the letter: Anthropic's engagement with the government has "yielded significant progress," the June 26 letter states. * "In addition, Anthropic has committed to work with the U.S. government on protocols and standards and releases for the Covered Models," the letter states, without elaborating. * The Commerce Department evaluated "diversion risks" presented in the models, and Lutnick determined that appropriate safeguards are in place. * "Accordingly, a license will no longer be required to export, reexport, or in-country transfer (including deemed exports and reexports) the Claude Mythos 5 Model to entities identified in Annex A to this letter and their foreign national employees, or to Anthropic's foreign national employees," the letter states. Between the lines: The government's June 12 order that prompted Anthropic to take down the models is part of ad hoc regulatory regime. * Export controls remain in place for all organizations not explicitly approved by the administration, and the letter does not change restrictions on Fable 5. * The loosening of restrictions on Anthropic comes after OpenAI's model was subjected to government reviews that the company said were not sustainable. Meanwhile, in the letter, Lutnick made clear that he can change his mind: "I reserve the right to reevaluate and adjust the scope of license requirements on the Covered Models, should circumstances change," the letter states. * Lutnick also reserved the right to change the list of entities that have access "at any time." * Semafor first reported on the letter. For the record: An Anthropic spokesperson told Axios that the company has received the notice and is now "working to provision the approved set of providers and restore their access to Mythos 5 as quickly as possible." * "We are pleased to see this progress and continue to work with the government to expand access to Mythos 5 and make Fable 5 available for general use again," the spokesperson added. Catch up quick: Lutnick slapped sweeping export controls on Anthropic after Amazon raised jailbreaking concerns, and the company failed to respond seriously, according to the administration. * It's not clear how exactly those concerns were addressed. What to watch: There's more regulatory uncertainty ahead, as an August deadline looms for implementation of a cybersecurity executive order. The order calls for federal agencies to create a formal process for assessing AI models' cyber capabilities.

US allows Anthropic to release Mythos to 'trusted partners'

The US government has partially lifted restrictions on Anthropic's advanced AI model, Claude Mythos 5, allowing trusted partners access after initial concerns about its potential misuse by adversaries. This move follows a two-week period where the AI firm collaborated with officials to address security risks. WASHINGTON: The U.S. government on Friday allowed Anthropic to release its powerful Claude Mythos 5 AI model to some "trusted partners," according to a Commerce Department letter seen by Reuters. The action comes two weeks after the government ordered the AI firm to suspend access to some of its models, due to fears they could be deployed ⁠by military ⁠intelligence users in China, Russia or other countries of concern. More than 100 companies and institutions will now have access to Mythos 5, including many Fortune 500 companies, a source familiar with the new directive said, declining to be identified due to the sensitivity of the matter.

"In just two weeks, we have worked diligently to ensure America remains the global leader in AI while safeguarding our security," a Commerce Department spokesperson said. The letter did not mention ⁠the status of Fable 5. The government is moving towards allowing Anthropic to release Fable as well, although a timeline is unclear, the source said. IPO-bound Anthropic's relationship with the U.S. government has been rocky this year. The company refused to allow the U.S. military to use its AI models for domestic surveillance and fully autonomous weapons systems and the government retaliated by putting it on a national security blacklist.

Anthropic nears deal with U.S. to lift AI model export restrictions By Investing.com

Anthropic is moving closer to an agreement with the Trump administration that could lead to the removal of U.S. restrictions on two of its most advanced artificial intelligence models, Bloomberg reported, citing people familiar with the matter. The report said Commerce Secretary Howard Lutnick has made progress in addressing the government's security concerns over Anthropic's Fable 5 and Mythos 5 models. The export controls could be lifted once officials across the administration approve the agreement, according to the sources. The discussions follow weeks of negotiations after the Commerce Department imposed restrictions on the two AI systems over concerns that users could bypass built-in safety guardrails. Senior Anthropic executives, including co-founder Tom Brown, have met with Lutnick and other administration officials in recent days, according to the report. U.S. officials have told the company the restrictions will be removed once the government's security concerns have been addressed. The timing of a final decision remains uncertain, as the White House and other agencies involved in shaping U.S. AI policy would also need to approve any agreement. Anthropic did not immediately respond to a request for comment. The restrictions were imposed about two weeks ago through a letter from Lutnick that barred Anthropic from allowing foreign nationals to access Fable 5 and Mythos 5. In response, the company suspended global access to both models while negotiations continued. The dispute marked one of the most significant U.S. government interventions in the operations of a major AI developer. It also came shortly after Anthropic confidentially filed for an initial public offering at a reported valuation of more than $900 billion. The administration has since widened its scrutiny of advanced AI systems. On Friday, OpenAI said it would limit access to a preview version of its GPT-5.6 model to a small group of government-approved partners following pressure from U.S. officials over concerns about the model's capabilities. Anthropic introduced its Mythos model in April to a limited group of organizations, citing cybersecurity risks. Earlier this month, it launched Fable 5 as a public-facing version with additional safeguards, while Mythos 5 was intended for a smaller group of cybersecurity institutions. Anthropic has argued that completely preventing users from bypassing AI safety protections is not currently possible for any frontier AI developer.
