U.S. Orders Anthropic to Suspend Fable 5 and Mythos 5 Access for Foreign Nationals
Summary: Anthropic said it received a U.S. government order at 5:21 p.m. ET on Friday instructing it to suspend all access to its Claude Fable 5 and Mythos 5 models for foreign nationals, inside or outside the U.S., and that it will abruptly disable the models for all users while it works to restore access. Anthropic said the government believes it found a method of bypassing or jailbreaking Fable 5, which the company reviewed as a narrow, non-universal technique used to identify a small number of previously known minor vulnerabilities that other publicly available models can also find without a bypass.
Why it matters: Anthropic's own Red Team says a lone operator can now turn a month's worth of patches into working exploits in a single afternoon for a few thousand dollars, which is why a single disputed jailbreak report was enough to pull a widely deployed commercial model offline for every user.
