Anthropic Kills Access to Fable 5, Mythos 5 After US Export Ban
Anthropic shuts down two AI models for all customers following a US government export control directive citing national security.
Anthropic is pulling the plug on Fable 5 and Mythos 5. Both models are being disabled for all customers, effective immediately.
The reason? A US government export control directive. Federal authorities invoked national security powers to force Anthropic's hand, ordering a full suspension of access to the models.
The directive specifically targets Fable 5, though Mythos 5 is also getting axed in the process. Details on what exactly triggered the order remain thin. The government hasn't elaborated on the specific national security concerns driving the decision.
For Anthropic customers, there's no workaround. Access is gone across the board — no exceptions, no carve-outs. It's a blunt instrument from Washington, and Anthropic is complying without public pushback.
This marks a significant escalation in government intervention over which AI models can operate and who gets to use them.
