Anthropic Accuses Alibaba of AI Model Distillation Campaign Impacting Claude System
Anthropic has accused Alibaba's Qwen AI lab of orchestrating a large-scale model distillation campaign against its Claude AI model. In a letter to U.S. Senators Tim Scott and Elizabeth Warren, Anthropic claims that Alibaba created approximately 25,000 fake accounts to generate over 28.8 million exchanges with Claude between April 22 and June 5, 2026. This operation allegedly targeted the model's advanced capabilities, including software engineering and agentic reasoning functionalities. Alibaba has denied these allegations, calling them baseless. Anthropic has previously raised concerns about similar activities by other Chinese AI labs.
