Anthropic flags massive unauthorized Claude distillation by Chinese AI labs
Anthropic says Alibaba, Moonshot, DeepSeek and other China-based labs conducted large-scale, unauthorized distillation of its Claude model to train their own systems, routing millions of exchanges and creating fraudulent accounts. The activity, spanning December 2025 to August 2026, included Alibaba’s operation with over 151 million Claude exchanges (May–July) and Moonshot/DeepSeek forwarding user requests to Claude to train their models, raising privacy and terms-of-service concerns and citing potential violations of laws.
