Summary
Anthropic has accused Chinese e-commerce giant Alibaba of conducting a large-scale "distillation attack" on its Claude AI model. According to a letter sent to the US Congress by Anthropic's head of policy Sarah Heck, Alibaba allegedly set up nearly 25,000 fraudulent accounts to generate over 28.8 million exchanges with Claude, targeting valuable capabilities like agentic reasoning, software engineering, and long-horizon tasks. This activity violates Anthropic's terms of service and access restrictions, raising concerns about intellectual property theft and unauthorized model exploitation.
