US halts Anthropic's Claude Mythos 5 after jailbreak alert
The U.S. government ordered Anthropic to shut down its advanced AI models, Claude Fable 5 and Mythos 5, worldwide after a suspected jailbreak that may have let a China-linked group bypass security rules. Officials say these models might be able to find software flaws on their own, which could be dangerous if hostile groups use them. The ban blocks foreign nationals everywhere from accessing the models, and only special licenses may allow future use. The sudden shutdown disrupted many businesses, and some legal questions about the government's authority and how to handle data remain open. Anthropic is trying to find a solution that would block only barred users instead of stopping access for everyone, but no timeline to restore service has been set.
