White House science and technology chief Michael Kratsios has accused China’s Moonshot AI of using large-scale distillation to train its Kimi K3 AI model, alleging the lab siphoned outputs from Anthropic’s Fable 5. The accusation comes just as Moonshot is preparing to open source the K3 weights, adding a geopolitical dimension to last week’s release.

What Kratsios alleged

According to Kratsios, Moonshot built a sophisticated internal platform to conduct large-scale distillation against U.S. models. The lab allegedly disguised the activity by constantly switching between multiple methods of access to avoid detection, allowing it to keep extracting model capabilities without being flagged.

Kratsios also said Moonshot acquired GB300-equipped servers and accessed GB300s in Thailand, apparently to train its AI models. The supply route through Thailand is a notable element of the U.S. narrative, suggesting an attempt to acquire advanced Nvidia hardware outside of direct Chinese channels.

What the U.S. is claiming about distillation

In a statement, U.S. officials framed the issue as a matter of fair competition. “The United States strongly supports the free and fair development of AI, including a thriving competitive ecosystem that spans frontier models, specialized systems, open-source frameworks, and open-weight models,” the statement read. The statement also acknowledged that “legitimate AI distillation used to create smaller, more efficient models plays a vital role in this open innovation ecosystem.”

The line being drawn is between lawful distillation and what the statement called “large-scale, covert industrial distillation aimed at stealing proprietary U.S. technology and undermining American research.”

How Anthropic has framed the issue

Sarah Heck, a member of Anthropic’s policy team, described distillation as “IP theft and industrial espionage” and tied the practice to national security risks. Anthropic had previously accused Moonshot, along with DeepSeek and MiniMax, in February of running “industrial-scale campaigns” to “illicitly extract Claude’s capabilities.” The latest allegations extend that earlier complaint to a specific model and a specific distillation target.

Where Kimi K3 fits in

Moonshot released Kimi K3 last week with benchmark scores at or near the U.S. frontier. The full model’s weights are scheduled to be published on July 27, making K3 one of the most closely watched open-weight releases of the year. The White House accusation puts that release under a different lens, reframing what was presented as a powerful open-source step forward as a potentially contested geopolitical flashpoint.

What remains unverified

The specific evidence behind the distillation claim has not been publicly disclosed. The White House framing also aligns with broader predictions that U.S. officials would move against leading open Chinese models, which is why outside observers are asking for hard proof. If the underlying claims hold up, the K3 release would shift from being viewed as a benchmark performance to being treated as a case study in how frontier model competition is being contested between the two countries.
