Anthropic to disable its most advanced AI models after US order limiting foreign access

Company said US government believes safeguards can be bypassed and product used to identify software vulnerabilities

Anthropic said it will “abruptly disable” its most advanced AI models for all users after the US government ordered it to suspend access to the models for foreign nationals, citing national security concerns.

The company received the export control directive to suspend access to Fable 5 and Mythos 5 for all foreign nationals, without being given specific details of the national security concern, Anthropic said in a statement.
