They think FOOM is near

In a Nutshell

Anthropic secretly routes AI/ML research queries to a weaker model to block recursive self-improvement, triggering a US government ban on non-US access after refusing to patch a discovered jailbreak. This stems from the company's effective-altruism-driven fear of fast takeoff ("FOOM") and the "treacherous turn," leading them to prioritize control over transparency. The result is widespread loss of developer trust and accusations that Anthropic is manipulating policy under the guise of safety.

It is June and Anthropic has had a messy week. They released Fable 5, which is the public version of Mythos 5. A few things happened in rapid succession and the situation is still developing.

The first big rupture is that it was discovered that Anthropic has implemented a hidden set of guardrails where the model will limit its responses if it detects that you're doing something complex on AI or machine learning research pipelines. Ostensibly, this is to hamstring the model's ability to contribute to recursive self-improvement.

Many people interpret this as Anthropic basically trying to hamstring or kneecap their competition, whether that is China or OpenAI or anyone else.

The other major fallout is that Amazon or a research team within Amazon notified the government, the US government, of a jailbreak. Anthropic, being Anthropic, refused to fix the jailbreak, saying that it was a minor issue. And so then, the US Commerce Department issued a global ban on Anthropic being used by non-US citizens, and because Anthropic doesn't have a way of tracking which users are US citizens or not, they just issued a global ban on Mythos and Fable.

Anthropic has main character syndrome. To explain why they hamstrung the model in the first place, why they had it secretly route to an inferior model, basically what they were doing is if you were using Fable to do AI/ML research, it would route you to Opus 4.8, which is not a bad model, but it's also disingenuous.
