Chinese artificial intelligence companies including Alibaba, DeepSeek and Moonshot AI used millions of exchanges with Anthropic's Claude to help train and improve their own models, Anthropic said. The company claims they sought to extract capabilities from its most advanced systems to advance their own.
Anthropic went on to describe "distillation" campaigns by seven China-based AI labs. The findings were included in the company's latest threat intelligence report, which covers misuse detected between December 2025 and August 2026.
