Brockman Calls Kimi K3 'Pretty Good,' Hedges on Distillation

On the same week a top Trump administration tech official accused China's Moonshot AI of industrial-scale distillation from Anthropic, OpenAI's own president took a notably softer line. According to Bloomberg, Greg Brockman called Moonshot's newly released Kimi K3 'a pretty good model' and said he wasn't sure whether the Chinese firm had piggybacked on OpenAI's technology to build it.

That measured framing lands hard against what Michael Kratsios said the same week. Kratsios, a top Trump administration tech official, claimed on X that 'Moonshot AI distilled Anthropic's Fable for the development of its K3 model,' calling the behavior 'large-scale, covert industrial distillation aimed at stealing proprietary U.S. technology and undermining American research.' He also alleged Moonshot had acquired servers containing Nvidia's restricted GB300 chips and deployed them in Thailand, 'likely to train its AI models.'

The stakes reach beyond one model. Sarah Heck, an Anthropic public policy executive, said Chinese theft of U.S. models 'creates serious national security risks for the United States,' and Treasury Secretary Scott Bessent has indicated he is considering placing Moonshot on a trade blacklist and imposing sanctions. If that happens, the argument about open-weight Chinese frontier models stops being a benchmark debate and starts being an export-control and sanctions story.

The honest caveat is that Brockman didn't rule distillation out, he just declined to confirm it, and the reporting doesn't show OpenAI presenting its own forensic evidence either way. Kratsios's public accusations, in what's been reported, read as assertions rather than published proof. Anyone treating the distillation claim as settled is getting ahead of what is actually on the record.

What to watch is whether OpenAI's tone stays this measured if Treasury actually moves. A blacklist would put every American lab with any China-facing collaboration in a harder posture, and a president publicly hedging on the central accusation is the kind of gap that regulators, competitors, and Moonshot's own lawyers will notice.
