Anthropic, a leading U.S. AI firm, has accused Alibaba of illicitly extracting capabilities from its Claude AI model through what it describes as the largest known distillation attack to date. According to UPI, Anthropic sent a letter to the Senate Banking Committee on June 10, detailing how Alibaba's AI lab and affiliated entities used approximately 25,000 fake accounts to initiate nearly 29 million interactions with Claude over six weeks beginning April 22.

The operation aimed to capture Claude's advanced abilities in processing complex prompts and decision-making. Anthropic emphasized the need for coordinated action between government and industry to combat such threats and maintain American AI leadership, as reported by CNBC. The firm also referenced previous allegations against other Chinese AI companies like DeepSeek, Moonshot, and MiniMax for similar activities.

Reuters noted that Alibaba did not immediately respond to requests for comment. Anthropic's letter was sent ahead of a scheduled Senate hearing on AI, highlighting the urgency of addressing these issues. The White House had previously warned against such activities in an April memo, which Alibaba allegedly disregarded.

The controversy comes amid broader tensions between U.S. and Chinese tech firms. Anthropic's allegations are part of a larger pattern of concerns about China's efforts to access and replicate advanced AI technologies developed by American companies. The firm has called for rapid, coordinated action among industry players, policymakers, and the global AI community to address these threats effectively.
