US orders Anthropic to halt foreign access to its most advanced AI models
Anthropic says it cut off all users after the Commerce Department ordered foreign-national access blocked, affecting models used by hundreds of millions, the company said.
- On Friday, Anthropic disabled access to Claude Fable and Claude Mythos for all customers following a U.S. government export control directive citing national security concerns.
- Commerce Secretary Howard Lutnick sent a letter to Anthropic CEO Dario Amodei after Axios reported another company claimed it could perform a "jailbreak" on Mythos, alarming the administration about national security risks.
- Anthropic argues the directive is based on a misunderstanding, noting the identified "jailbreaking" technique revealed only minor vulnerabilities also present in other models, including OpenAI's GPT-5.
- The directive prevents access by any foreign national, whether inside or outside the United States, forcing Anthropic to disable the systems for all customers to ensure full compliance.
- Anthropic launched the models on Tuesday, initially releasing Claude Fable publicly while restricting Claude Mythos to Project Glasswing participants, though other company models remain unaffected by the order.
