Chinese AI startup Z.ai unveiled GLM-5.3, an open-weight AI model with unexpectedly strong cybersecurity capabilities that rivals Anthropic's Mythos 5 and OpenAI's GPT-5.6 Sol in vulnerability discovery. The model scored 84.5% on CyberGym but trails competitors on exploit development. Z.ai is delaying public release for two weeks to strengthen safeguards amid concerns about malicious actors exploiting advanced cyber capabilities.
OpenAI cut GPT-5.6 Luna prices by 80% while Anthropic launched Claude Opus 5 at half its flagship cost as the AI price war intensifies. US labs reduced token prices by nearly 25% since mid-July to compete with Chinese rivals Moonshot and DeepSeek, who are capturing cost-conscious enterprise customers from DoorDash to Airbnb.
The AI competition between OpenAI and Anthropic intensifies as new data reveals OpenAI's annualized revenue exceeds $40 billion with 20% month-over-month growth in July. Despite Anthropic's $47 billion revenue lead and 44% market share among business users, OpenAI is gaining ground through new privacy features and enterprise products.
OpenAI replaced chief revenue officer Denise Dresser after just eight months, naming Wiz's Dali Rajic as her successor. The move marks the latest in a wave of executive departures that has seen COO Brad Lightcap and CEO of AGI deployment Fidji Simo exit, while co-founder Greg Brockman quietly expands his authority over commercial operations ahead of the company's impending IPO.
CrowdStrike is democratizing access to advanced AI security by expanding Project QuiltWorks to small and medium-sized businesses worldwide. Through partnerships with seven global distributors including Pax8, TD Synnex, and Arrow Electronics, the company aims to protect SMBs against AI-discovered vulnerabilities using frontier models from OpenAI and Anthropic.
Nvidia announced $500 billion in AI chip financing and $105 billion support for OpenAI's Ohio data center as its competitive edge shifts from technology to capital deployment. Meanwhile, Michael Burry and Steve Eisman warn of mounting financial risks from off-balance-sheet commitments and dependence on OpenAI and Anthropic.
Anthropic is negotiating to acquire Israeli AI startup Decart for approximately $6 billion, marking its largest deal yet. The acquisition targets Decart's chip optimization technology that could dramatically reduce Anthropic's ballooning compute expenses as it prepares for a public listing.
Anthropic upgraded its Chrome browser extension to run full Claude Cowork sessions in the sidebar. The AI-powered work assistant now syncs conversation history, skills and connectors across desktop, web and mobile. Users can automate tasks across vendor portals and legacy systems while maintaining context between devices.
Security researchers uncovered a critical API vulnerability affecting OpenAI, Anthropic, and Google that allowed weaker AI models to decode encrypted reasoning from stronger models. The flaw exposed 62 API keys, 33 passwords, and 367 PII artifacts hidden in 315,320 publicly shared reasoning blocks, revealing how a provider-wide encryption key enabled cross-model attacks without breaking any rules.
An investigation using a hidden AirTag has exposed Amazon's systematic destruction of rare books at its Las Vegas VGT3 facility. The tech giant is buying bulk orders of rare books, cutting their spines, and scanning them to train AI models, raising ethical concerns among book lovers and independent bookstores worldwide.
Anthropic reported a $65 billion annual revenue run rate by July's end, up from $47 billion in May and $9 billion at 2025's close. The AI startup led by Dario Amodei now targets an October IPO that could value the company at $2 trillion or more, making it the largest public offering ever and testing investor appetite amid rising AI costs and regulatory pressure.
Bitcoin miner Riot Platforms has signed a $9.1 billion, 20-year compute deal with Anthropic, leasing 191 megawatts at its Rockdale, Texas campus. The agreement marks a major shift as bitcoin miners transition to AI infrastructure landlords, with the deal potentially reaching $16.1 billion if extended.
Riot Platforms secured a 20-year AI data center lease worth $9.1 billion with a frontier AI lab reported to be Anthropic, covering 191 megawatts at its Rockdale facility. The deal marks a decisive shift from Bitcoin mining to AI infrastructure, driving the stock up 24% in after-hours trading as analysts raised price targets to as high as $40.
Anthropic has begun watermarking all Claude AI outputs globally to meet EU AI Act requirements. Text carries invisible watermarks while images include cryptographic metadata. But researchers question effectiveness as watermarks can be stripped easily, and users worry about false positives flagging legitimate editing as AI-generated content.
Anthropic announced that auto mode will be turned on by default in Claude Code starting August 14 for Pro, Max, and Team account users. The AI programming tool will now proceed autonomously without requesting permission at each step, using an automatic classifier that caught 89 percent of harmful actions in testing compared to just 13.6 percent caught by humans.
