Anthropic says has taken its latest AI models offline to comply with new export controls

Anthropic announced on Friday it has temporarily removed its latest AI models, Fable 5 and Mythos 5, from public access to comply with a U.S. government directive. The move follows a Trump administration order aimed at restricting access to advanced AI systems by foreign nationals, marking the most significant export control effort to date. The directive was issued without specifying the national security concerns prompting the action. Anthropic stated it received the order on Friday afternoon and disagreed with the process, arguing the government should use a transparent, fair, and technically grounded statutory framework to block unsafe deployments. The company called the decision a misunderstanding and expressed hope to restore access as soon as possible. Fable 5 was released widely earlier this week, while Mythos 5 had already been restricted due to cybersecurity fears. The Commerce Department did not immediately respond to requests for comment. The government’s action comes just 10 days after President Donald Trump signed an executive order establishing a voluntary framework for AI developers to vet national security risks before public release. Under the order, developers could submit their systems for up to a month of review, though participation is not mandatory. Anthropic’s compliance reflects broader tensions between private AI companies and regulatory oversight, particularly regarding export controls and national security implications. The company’s statement underscored its stance that such decisions should be based on clear technical evidence and open processes.
