U.S. Government Orders Anthropic to Pull Two AI Models Over Jailbreak Concern. The Company Says the Evidence Was Verbal and Unspecific.
The Trump administration issued an export control directive ordering Anthropic to disable its two newest AI models, Fable 5 and Mythos 5, citing national security concerns it has not made public. Anthropic complied but is pushing back, saying the government provided only 'verbal evidence of a potential narrow, non-universal jailbreak' and that pulling a model deployed to hundreds of millions of people over that threshold is disproportionate. The order lands as Anthropic navigates a supply chain blacklist, a pending IPO, and an ongoing dispute with the Pentagon over military use of its AI.
