US orders Anthropic to halt foreign access to its most advanced AI models

Anthropic said on Friday it has been ordered by the US government to suspend access for all foreign nationals to its Fable ‌5 ⁠and ⁠Mythos 5 artificial intelligence models, citing national security concerns. The company said it received the export control directive on Friday from the government, which gave no specific details of its ⁠national security ‌concern. It is Anthropic’s understanding, however, that the government believes ⁠it has become aware of a method of bypassing, or “jailbreaking,” Fable 5, according to the company’s statement.
