Anthropic accuses Chinese rival Alibaba of illicitly extracting AI capabilities

US artificial intelligence (AI) giant Anthropic has accused Chinese e-commerce and technology firm Alibaba of brazenly and illicitly extracting its Claude AI model's capabilities. In a letter sent to two members of the US Congress, the San Francisco-based company said operators linked to Alibaba carried out almost 29 million exchanges with Claude using thousands of fraudulent accounts in what it called the largest extraction campaign of its kind. Anthropic urged Congress to penalise the companies behind attacks like this and to ramp up measures to prevent US tech from being stolen. The BBC has contacted Alibaba for comment and requested more details from Anthropic. Anthropic's letter, dated 10 June and addressed to US Senators Tim Scott and Elizabeth Warren, accused New York Stock Exchange-listed Alibaba of carrying out the largest campaign to illicitly extract Claude's capabilities.
