US Commerce Order Forces Anthropic to Disable Fable 5 and Mythos 5

On the night of June 13, 2026, Anthropic received an export control directive from the US Commerce Department ordering it to cut off foreign nationals' access to its latest models, "Fable 5" and "Mythos 5," and temporarily disabled both models for all users. The company calls the move a "misunderstanding" and continues to negotiate with the administration, but the matter remained unresolved as of June 17.
