Treasury Threatens Sanctions After White House Claims Moonshot Distilled Anthropic's Fable
U.S. Treasury Secretary Scott Bessent reiterated his warnings to Chinese artificial intelligence companies on Wednesday. He stated that sanctions remain a possibility after a White House official accused Moonshot of improperly distilling Anthropic's Fable model.
Model distillation is a common AI training technique. In this process, a smaller model learns from the outputs of a larger one. While this method can infringe on intellectual property rights, it is also widely used as a legitimate optimization approach.
"Open source is not open season on American IP," Bessent posted on X. "When [Chinese] firms conduct covert, industrial-scale distillation attacks that cross the line into IP theft, sanctions and Entity List designations will be on the table."
Earlier this week, Bessent stated that the U.S. government would examine open source models from China for signs of intellectual property theft. He said sanctions would be imposed if such theft is found.
White House Official Accuses Moonshot
Bessent's latest remarks came hours after Michael Kratsios, the White House's science and technology policy chief, accused the China-based Moonshot of conducting large scale distillation against U.S. models. Kratsios alleged that Moonshot had acquired Nvidia's "GB300-equipped servers and has accessed GB300s in Thailand, likely to train its AI models." This raised questions about whether the firm violated U.S. export control rules.

The GB300 servers are part of Nvidia's Blackwell generation. These servers are banned from being sold to Chinese companies.
Experts Question Distillation Claims
Some experts dispute the idea that Moonshot's Kimi K3 model could have been developed primarily through distillation from Fable. Fable has only been publicly available since July 1. Moonshot released K3 last week as an open-weight model. Its advanced capabilities have called into question the underlying business models of leading U.S. AI labs. The release has cast doubt on whether these labs can continue to justify the enormous capital requirements that underpin the frontier AI race.
Broader Debate Over Chinese Open Models
The episode has also intensified a broader debate in Washington over the influx of Chinese open models. Some, including former White House AI advisor and current OpenAI Head of Strategic Futures Dean Ball, have argued that the U.S. should restrict or effectively ban the use of Chinese open-weight models. They say this would preserve America's technological advantage and mitigate potential national security risks.
