Anthropic accuses Alibaba of systematically reverse-engineering Claude
Source: Bloomberg (paywall)
Anthropic's formal complaint to U.S. officials alleges that Alibaba used roughly 25,000 accounts to query Claude nearly 29 million times over three months—a pattern consistent with extracting training data to build competing models rather than legitimate usage. The complaint escalates commercial and geopolitical tensions over AI model access, forcing cloud providers and regulators to distinguish between normal API consumption and coordinated intelligence gathering. It also signals that frontier AI companies now treat their models as defensible intellectual property worth protecting through government intervention.
