The U.S. Treasury is warning that it could impose sanctions on Chinese AI company Moonshot after White House officials alleged that Moonshot used output “distillation” from Anthropic’s Fable model to help develop its Kimi K3 system. Treasury Secretary Scott Bessent said the government is investigating whether certain Chinese AI models were built using methods that amount to illegal appropriation of U.S. technology. The claims are tied to the broader U.S. stance that distilling proprietary models and training systems on the basis of American AI outputs can constitute covert theft.
According to the reports, U.S. officials contend they have found evidence suggesting large-scale use of distillation techniques involving American AI systems. As part of the inquiry, Washington is expected to assess whether the relevant open-weight models and their developers violated U.S. laws or other restrictions related to intellectual property and export or technology controls.
The possible sanctions would reflect escalation in U.S.–China technology tensions, but the reports do not describe a final decision or specific penalties.
