US authorities accuse Chinese AI companies of industrial-scale campaigns to copy American models

U.S. agencies report that Chinese firms DeepSeek, Moonshot AI, Alibaba, MiniMax, StepFun and Z.AI have extracted billions of tokens from Anthropic’s Claude, OpenAI’s GPT, Google’s Gemini and xAI’s Grok since 2024 to train their own models. DeepSeek used Claude, Gemini, GPT and Grok data for its R1 model, while Moonshot AI incorporated Claude’s Fable and GPT-4o data into Kimi K3 and Kimi K2, respectively, and the advisory includes mitigation steps for U.S. companies.
