Anthropic details distillation campaigns from Alibaba, Moonshot AI, and DeepSeek

Anthropic’s report documents five distillation campaigns that generated nearly 200 million exchanges to extract Claude’s chain-of-thought reasoning, targeting agentic abilities, tool use, coding, data analysis, and logical reasoning. The largest effort, attributed to Alibaba, produced 151 million exchanges from May to July 2026 across 3,500 accounts, while a Moonshot AI campaign routed about 300 000 requests through 5 000 accounts to probe surveillance footage using the Opus model.
