Anthropic joins OpenAI in flagging 'industrial-scale' distillation campaigns by Chinese AI firms

Anthropic accused three Chinese AI companies (DeepSeek, Moonshot AI, and MiniMax) of running large-scale distillation attacks, which involve flooding an AI model with specially crafted prompts to extract knowledge and train smaller competing models. The companies allegedly used commercial proxy services to bypass Anthropic's restrictions and created over 24,000 fraudulent accounts to generate roughly 16 million exchanges with Claude, with MiniMax responsible for over 13 million of those exchanges.
