Anthropic disables Fable and Mythos AI models after U.S. export controls bar foreign access, including own employees

Anthropic was forced to disable all access to its newest AI models, Fable 5 and Mythos 5, late on Friday after the U.S. Commerce Department used national security export controls to bar the company from distributing the models to any foreign national.

The directive includes not just people located outside the U.S., but also any foreign national in the U.S., including Anthropic's own non-citizen employees.

Given the scope of the directive, Anthropic argued it had no choice but to disable the models for all users.

Anthropic called the government position 'a misunderstanding'.
