Restrictions on Anthropic's advanced AI models, Mythos 5 and Fable 5, have been imposed due to national security concerns, as confirmed across multiple sources. The White House informed Anthropic in a Friday letter that under a new export control directive, neither model may be used by any foreign national in the United States, including Anthropic employees on work visas. Mythos 5 was released only to a small group of cyberdefenders and infrastructure providers in collaboration with the U.S. government, according to Reason.com. Anthropic's newest public-facing model is called Claude Fable 5, as reported by Reason.com. Public access to these models has been restricted. According to Times of India, Anthropic is sending senior technical staff to Washington to meet with White House officials and is actively engaging in discussions to address national security concerns and restore access to its most capable AI systems for users worldwide.
