Can the U.S. government legally gatekeep global access to AI models?

The disabling of Claude Fable 5 and Mythos 5 marked the first time the government used export controls to prevent foreign access to an AI service.

When the U.S. Commerce Department ordered Anthropic on June 12 to immediately prevent all foreign nationals from using the artificial intelligence company’s two most advanced large language models, Anthropic disabled its Claude Fable 5 and Mythos 5 models within hours, making them inaccessible to everyone.
