The NSA, CISA and the FBI have accused DeepSeek, Moonshot and other Chinese AI companies of "distilling" American frontier AI models. US authorities accuse Chinese AI companies of industrial-scale campaigns to copy American models. News AI US authorities accuse Chinese AI companies of industrial-scale campaigns to copy American models The NSA, CISA and FBI have issued a joint cybersecurity advisory.

Specifically, the agencies are accusing DeepSeek, Moonshot AI, Alibaba, MiniMax, StepFun and Z.AI of extracting "billions of tokens across millions of exchanges/requests" from American models, including Anthropic’s Claude, OpenAI’s GPT, Google’s Gemini and xAI’s Grok, since 2024. Distillation is the term for a method in AI development in which the output of a powerful model is used to train newer ones. The warning states that DeepSeek used data and capabilities from various Claude, Gemini, GPT and Grok models to train its own, including the R1.

That’s the powerful, open-source reasoning model the company released in early 2025. Moonshot AI, the agencies said, extracted "significant" data from Claude’s Fable to train Kimi K3, which is considered one of the most advanced models developed by a Chinese company. Anthropic created Fable to bring some of the capabilities of Mythos, its modern cybersecurity model exclusively available to Project Glasswing participants, to the public.

Similarly, Moonshot’s Kimi K2 used GPT-4o data, the agencies add.
