Anthropic cuts off Fable 5 and Mythos 5 access following government order

Article excerpt

Anthropic has shut down access to its Fable 5 and Mythos 5 AI models worldwide following a government order issued Friday evening. The directive, citing national security concerns, required the company to block access for foreign nations and even its own employees. Anthropic complied immediately but said the government provided no specific details about what triggered the restriction. The move marks a rare instance of U.S. authorities directly ordering an AI company to disable models, raising questions about what capabilities prompted the intervention.
