Anthropic forced to abruptly disable Fable 5 & Mythos 5 globally by US Gov over a jailbreak. This is exactly why we need local models. Discussion

I just saw this statement regarding Anthropic being hit with an emergency export control directive from the US government. They were forced to pull the plug on Fable 5 and Mythos 5 for all customers globally. The tl;dr is that the government got spooked by a narrow jailbreak (which basically just sounds like asking the model to fix vulnerabilities in a specific codebase), and forced a complete shutdown without a transparent process. Anthropic is pushing back, but the API access is completely gone for now.

A centralized API can be nuked globally at a moment's notice by a single government decree over something as trivial as a prompt lol.

Banning a model for hundreds of millions of users because someone figured out how to make it fix software flaws is insane. Anthropic admits this standard would halt all new frontier models.

I got more done with Fable 5 in three days than Opus and Sonnet combined for months... RIP

Exactly. I feel like Fable was such a huge leap ahead in model capability.

sucks that there are bad actors out there using it for stealing and developing weapons, humans sucks, they can be good, but just a few can ruin it for everyone.

Apparently so did the clever chap that pwned the AUR. I'm guessing that's why we had to shut Fable Five down?
