Treasury threatens sanctions after White House claims Moonshot distilled Anthropic’s Fable

Scott Bessent isn't backing down. The Treasury Secretary spent Wednesday reinforcing a warning he'd already made days earlier: Chinese AI companies caught stealing American intellectual property through distillation could face sanctions and Entity List designations. His post on X was blunt. Open source, he wrote, is not open season on American IP.

The timing wasn't random. Bessent's remarks landed hours after Michael Kratsios, the White House's science and technology policy chief, publicly accused Moonshot of running large-scale distillation against U.S. models — specifically Anthropic's Fable. Distillation itself is nothing exotic; it's a standard technique where a smaller model learns by studying a bigger one's outputs, and plenty of legitimate optimization work relies on it. The trouble starts when that process becomes a vehicle for lifting someone else's IP wholesale, which is the line Kratsios is alleging Moonshot crossed.

Kratsios didn't stop at distillation. He also claimed Moonshot got its hands on Nvidia's GB300-equipped servers and accessed GB300 hardware in Thailand, likely to train its models. That matters because the GB300, part of Nvidia's Blackwell lineup, is barred from sale to Chinese firms under export controls. If true, it's not just an IP dispute anymore — it's a potential violation of U.S. export rules, which raises the stakes considerably.

But the accusation has holes, according to some experts, and the timeline is the problem. Fable has only been publicly available since July 1, which makes it awkward to argue it was the primary source material behind Moonshot's Kimi K3, an open-weight model the company shipped just last week. K3's capabilities have already rattled Washington and Silicon Valley alike, prompting uncomfortable questions about whether the enormous capital pouring into frontier AI labs in the U.S. is still justified if a Chinese open model can compete.

That unease is fueling a wider argument in Washington over what to do with Chinese open-weight models generally. Dean Ball, formerly a White House AI advisor and now at OpenAI, has pushed for restricting or outright banning their use, framing it as a matter of preserving America's technological edge and closing off national security risks. Moonshot and the Treasury haven't responded to requests for comment, so for now this is accusation versus silence — with sanctions hanging in the balance depending on which version holds up.
