Anthropic report alleges Alibaba, Moonshot AI and DeepSeek used Claude outputs without authorization to train their own models
Issue disclosure
Anthropic said in a threat intelligence report released on September 10, 2026 that it detected and disrupted unauthorized large-scale 'distillation' of its Claude models by China-based AI labs including Alibaba, Moonshot AI and DeepSeek, which allegedly used Claude outputs to train and improve their own models such as Qwen and Kimi.
Stated objective. The activity was aimed at extracting capabilities from Claude to help train and improve other AI models
Source excerpt
The company said the activity was aimed at extracting capabilities from Claude to help train and improve other AI models.
Anthropic said operators affiliated with Alibaba used Claude outputs to help train its Qwen models, while Moonshot routed some Kimi user requests to Claude and used some of the resulting exchanges to train its own models.
The company said DeepSeek — which rose into prominence last year due to its capabilities and cheap costs — also used tactics similar to Moonshot, transferring exchanges to Claude without notifying DeepSeek customers.
