US Orders Claude's Top Models Offline
12JUN
The US government forced Anthropic to pull its two best models worldwide. The export order bars all foreign nationals, so Anthropic shut access for everyone. First time Washington recalled a live frontier model.
On June 12, the government cited national security and barred Fable 5 and Mythos 5 to any foreign national. Anthropic can't screen nationality in real time. So it pulled both for everyone.
The trigger was a jailbreak. Anthropic says it was narrow, unlocking one Mythos cyber feature, not a full break of Fable 5. It is fighting to restore access.
If one narrow jailbreak can recall a model used by hundreds of millions, every frontier lab now ships under that risk. Watch if OpenAI and Google get the same.
