THREE DAYS AGO Three days ago, Anthropic released the most powerful AI model ever made. Today, the US government forced them to shut it down. Here's what happened. Wait, the government actually shut down an AI? Like completely? Completely. It's called Claude Fable 5. On June 9th, Anthropic launched it and it immediately broke every benchmark in AI. It migrated 50 million lines of code for Stripe in one day. A job that would take an entire engineering team two months. 50 million lines in one day. That's not even the crazy part. They gave it Pokemon Fire Red with zero help. No maps, no tools, just raw screenshots. It beat the game by itself using only its eyes. Previous AI models couldn't even get past the first gym with full assistance. It beat Pokemon just by looking at the screen. Okay, that's actually insane. But here's where it gets scary. Mythos 5, same model, but with no safety limits. It designed real drug compounds. Nine out of 14 protein targets produced actual candidates for medicine. It matched or beat trained human scientists with zero human help. So it's doing the job of actual scientists now. And finding cybersecurity exploits better than any hacker alive. It could discover software vulnerabilities, break into systems, move through networks. Anthropic's own testing showed it could perform full cyber attacks autonomously. That's why they kept Mythos locked to the US and a few cyber defenders. Hack design drugs and write code faster than humans. Why would they release this? They thought the safety filters were enough. Fable 5 had classifiers that blocked dangerous requests and fell back to a weaker model. It worked on 95% of sessions. But someone found a way to jailbreak it. And that jailbreak reached the US government. And they panicked. On June 12th at 5:20 PM Pacific, the Trump administration sent Anthropic an export control directive. Shut it down for every foreign national on Earth, including Anthropic's own foreign employees. Three days after the most powerful AI ever made went dark. API calls started returning errors at 6:59 PM Pacific. Gone. So it was too smart to exist. Anthropic says the jailbreak was minor. Other models can do the same thing. They're fighting it. The first time in history a government has killed an AI model over national security. Follow. This story isn't over.
