US government orders Anthropic to disable Claude Fable...
Anthropic asked for a referee. It got a sledgehammer instead. In a sudden, silent move, the U.S.
government has ordered the company to disable its Claude Fable 5 and Mythos 5 models for every user on the planet. No public hearing. No detailed technical briefing.
The immediate, global order shreds the company's carefully crafted principles about transparent regulation. The models are offline. The reason is a state secret.
According to Anthropic, the government believes it has found a method to bypass Fable 5's safety measures. The company says it reviewed a demo of the technique and found it identifies only "a small number of previously known, minor vulnerabilities" that other publicly available models could also detect.
So much for that. Anthropic is now a brutal case study in unintended consequences. The company championed a government kill switch.
Someone in Washington just used it. They wanted a process grounded in technical facts; they received a classified directive. This isn't the sober oversight they sketched in blog posts.
It's raw power, executed quietly.
One desk in one building just turned off a piece of the global internet. That action proves a state can do it. It does not prove why it should.
The lack of public justification—the secrecy—creates a dangerous template. A tool built for an existential safety risk can be repurposed for anything a bureaucracy defines as one. The debate has shifted.
It's no longer about AI safety. It's about who gets to decide what safety means, and what they get to hide while deciding it. Good intentions make poor law.
The companies wanted rules. Now they have a ruler.
