Anthropic, a US artificial intelligence company, has accused Alibaba, the Chinese tech and e-commerce giant, of illegally extracting capabilities from its Claude AI model. The company claims this represents the largest attack of its kind it has ever faced. According to a letter reviewed by Reuters, the operation involved a systematic effort to replicate Claude’s functionalities. Details of how the extraction occurred were not immediately released, but Anthropic alleges a deliberate and substantial breach of its intellectual property. This accusation raises concerns about intellectual property protection in the rapidly evolving AI landscape and the potential for corporate espionage. The incident could escalate tensions between US and Chinese tech companies, particularly in the competitive field of artificial intelligence. Anthropic has not yet specified what actions it will take in response to the alleged theft.
