Anthropic vs. the U.S. Government

As of June 13, 2026, Anthropic's two most capable models, Fable 5 and Mythos 5, are disabled for all customers worldwide. A U.S. Commerce Department export-control directive issued June 12 bars access by any foreign national, invoking the deemed-export rule at 15 CFR 734.13; because the models cannot be selectively restricted by nationality, Anthropic disabled them entirely. The government cites a potential 'jailbreak' of Fable 5 but has released no public document and no signed statement, and nothing appears in the Federal Register; the directive exists only as a private letter to the company. Anthropic disputes the order, calling the cited vulnerability narrow and non-universal, and says it is working to restore access. The action follows a months-long conflict: collapsed Pentagon contract talks over Anthropic's refusal to permit mass surveillance and fully autonomous weapons, the Defense Department's designation of Anthropic as a supply-chain risk, and Anthropic's lawsuits against the DoD.
