US government officials have leveled serious accusations against Chinese artificial intelligence company Moonshot AI, claiming the firm covertly leveraged Anthropic’s proprietary technology to develop its Kimi K3 model, which debuted on July 16.

We have information that Moonshot AI distilled Anthropic’s Fable for the development of its K3 model.
To do this they developed a sophisticated internal platform to conduct large scale distillation against U.S. models, allowing them to quickly switch between multiple methods of…

The allegations came from Michael Kratsios, who serves as director of the White House Office of Science and Technology Policy, in a Wednesday statement posted to X.

“We have information that Moonshot AI distilled Anthropic’s Fable for the development of its K3 model,” Kratsios stated.

According to Kratsios, Moonshot AI constructed a secret internal infrastructure designed to facilitate widespread distillation of American AI systems. This platform purportedly enabled the firm to rotate between different access approaches to evade detection.

The White House official further claimed that Moonshot AI bolstered its computational resources by obtaining servers located in Thailand for model training purposes.

Since its launch, Kimi K3 has earned recognition as among China’s most advanced AI systems. The allegations reflect mounting anxiety in Washington that Chinese technology companies are leveraging American models to accelerate their domestic AI innovation efforts.

The Distillation Debate

The White House’s assertions have not gone unchallenged within the AI research community.

Several AI experts have expressed skepticism, arguing the compressed timeline between Anthropic’s model availability and Kimi K3’s debut makes the distillation theory technically questionable.

Anthropic re-released its Fable 5 model on July 1 following the removal of export controls. Kimi K3 appeared merely 15 days afterward on July 16.

Elie Bakouch, who researches at AI startup Prime Intellect, challenged the plausibility of this timeline. “I don’t think claiming that K3’s performance comes from Fable distillation makes sense technically,” he noted.

Dean Ball, who leads strategic futures at OpenAI, similarly expressed doubt. He stated his belief that Kimi K3’s capabilities cannot be attributed to distillation processes alone.

The administration has yet to make public any concrete evidence supporting these allegations. Moonshot AI has remained silent on the matter as of publication.

Sanctions on the Table

Treasury Secretary Scott Bessent emphasized that the government treats large-scale distillation operations as a significant threat.

“Open source is not open season on American IP,” Bessent declared.

He cautioned that Chinese companies engaging in covert mass distillation activities could face economic sanctions and addition to the Entity List, a restrictive trade measure that curtails access to American technology.

Kratsios emphasized a difference between lawful distillation practices, which produce compact and efficient models, and what he characterized as outright theft of American intellectual property.

Earlier this month, Anthropic verified that the US Department of Commerce had removed export limitations on its most advanced models, including Fable 5 and Mythos 5. The company indicated it restored international access immediately thereafter.

With both Moonshot AI and Anthropic reportedly pursuing initial public offerings, the controversy carries significant financial implications.

The US government continues to assess its response to the purported violations.
