# Claude Fable 5 Returns After US Export Controls Lifted

> Anthropic's Claude Fable 5 has had an unusually turbulent debut. Released on June 9 as the first publicly available model in its Mythos class, it was pulled offline on June 12 after a US government export directive, prompted by Amazon researchers who found jailbreaks that could coax it into generating exploit code. Those controls were lifted June 30, and Fable 5 returned to general availability on July 1. The model itself sits at the frontier, running with always-on adaptive thinking, a 1 million-token context window, and up to 128,000 tokens of output, aimed at software engineering, scientific research, and heavy knowledge work. It is not cheap, priced at 10 dollars per million input tokens and 50 dollars per million output, roughly double Opus 4.8. The saga is the real story. A government directive briefly forced a commercial frontier model dark over security concerns, and its return now carries a 30-day traffic-retention requirement. That is a preview of how state power and frontier AI are starting to collide.
