US Government Directs Anthropic to Suspend Fable 5 Access
Acting on a national security directive, all foreign national access to Fable 5 and Mythos 5 has been suspended, necessitating the immediate disabling of these models for all customers. The directive stems from the government’s belief in a method to bypass Fable 5’s safeguards, though Anthropic’s review found the demonstrated vulnerabilities to be minor and present in other publicly available models. Anthropic maintains its “defense in depth” strategy for Fable 5, which they believe mitigates risks to levels comparable with existing industry models, and disagrees that the disclosed narrow jailbreak warrants recalling a widely deployed commercial model.
