Chinese AI firms are stealing proprietary capabilities belonging to US-based AI models via massive distillation campaigns, acccording to US government agencies.
The FBI, the National Security Agency (NSA), and the Cybersecurity and Infrastructure Security Agency (CISA) published a joint advisory on Sept. 8, warning that Chinese AI firms were conducting "industrial-scale" efforts to extract capabilities from leading US AI models. The advisory accuses a number of AI vendors — including Alibaba, DeepSeek, MiniMax, Moonshot AI, StepFun, and Z.AI — of using US large language models (LLMs) to assist training and development of their own proprietary models.
These companies supposedly "extracted billions of tokens across millions of exchanges/requests from U.S. frontier AI models, including variants of Claude, GPT, Gemini, and Grok, since at least late 2024," the advisory stated.
