The US government’s Anthropic models ban was never about an AI jailbreak

The U.S. Commerce Department used an export control directive to force Anthropic to take its Fable 5 and Mythos 5 AI models offline, citing national security concerns without providing specifics. Security experts argue the action was based on a misunderstanding of a guardrail bypass (a method to get an AI to ignore its safety restrictions) that cannot be meaningfully fixed without weakening the models' security capabilities, and they contend the government's intervention appears retaliatory rather than justified by technical merit.
