US Orders Anthropic to Block Foreign Access; Fable 5, Mythos 5 Halted

The US Commerce Department issued an export control directive on June 12, 2026, barring foreign nationals from accessing Anthropic's Claude Fable 5 and Mythos 5, prompting Anthropic to immediately suspend the two models for all users. The directive cited national security concerns tied to jailbreaks (bypassing safety guards) and covered foreign nationals inside and outside the US, including Anthropic employees. To comply, Anthropic cut off access for all users, though other Claude models were unaffected. (1, 2)
