Anthropic Disables Top AI Models On US Order

Anthropic has disabled its top-tier AI models, Fable 5 and Mythos 5, following a US government export control directive ordering the suspension of access for all foreign nationals. The company was not provided with specific details regarding the national security concern behind the order. Anthropic, known for its focus on AI safety and research, employs dedicated teams to stress-test models and build protective safeguards, though these defenses are acknowledged to remain fragile.
