Commenters on Downdetector were joking and speculating that the outage meant Claude Fable 5 was making a return, but that's not what happened.
Fable 5, which is the mass market version of Anthropic's powerful Mythos 5 model, was released last week. Anthropic pulled access to the model Friday after the US government imposed export controls, barring any foreign nationals from using it. The Trump administration said there was a jailbreak that would allow users to skirt the guardrails in Fable, but Anthropic says the issue isn't as serious as the government has claimed and objected to the order.
