Inside the fight over Claude Mythos 5

Article excerpt

Anthropic received a US export control directive on Friday evening ordering the company to suspend access to its Mythos 5 and Fable 5 AI models by foreign nationals, including its own international employees. The order came as the country celebrated sports victories, forcing Anthropic into a weekend confrontation with the Trump administration. Implementing the directive would have required the company to completely restructure how it operates, since the models run on shared infrastructure that foreign employees access regularly. The clash highlights growing tensions between AI companies and government restrictions on advanced technology exports.
