US Halts Access to Anthropic's New Fable 5, Mythos 5 Under Export Controls

Anthropic said that around June 12, 2026, it immediately disabled all customer access to its latest AI models, Claude Fable 5 and Claude Mythos 5, after the US government issued an export control directive citing national security authorities. The directive requires suspending access to both models for any foreign national inside or outside the United States, including Anthropic's own foreign national employees. To comply, the company simultaneously cut off access for all customers, though it said other Claude models are unaffected. Details
