US Accuses Chinese AI Firm Moonshot of Stealing Anthropic's Fable Technology for Kimi K3

The United States government has publicly accused Chinese artificial intelligence company Moonshot AI of stealing technology from Anthropic's Fable model, alleging the stolen technology was used to build Moonshot's latest Kimi K3 model.

White House technology official Michael Kratsios strongly condemned the alleged action, characterizing it as a "covert industrial distillation" campaign aimed at stealing proprietary US technology and undermining American research, according to TRT World. Kratsios called such activities "unacceptable."

Industrial distillation is a technique where competitors extract capabilities from a target model by sending large numbers of queries and using the outputs to train their own models. This practice has become a flashpoint in US-China AI competition, with several American AI companies previously accusing Chinese counterparts of using distillation to replicate model capabilities.

Moonshot AI is among China's leading large-model startups, known for its Kimi series' long-context processing capabilities. Anthropic's Fable model represents the company's core offering in multimodal and reasoning capabilities. The accusation elevates a corporate technology dispute to the governmental level.

Neither Moonshot AI nor Anthropic has issued a public response to the allegations at the time of reporting.

This development could further strain US-China relations in the AI domain. The US government has been tightening technology export controls on Chinese AI companies, and distillation-based accusations may provide grounds for even stricter regulatory measures. The key question ahead is whether this represents an isolated case or the beginning of broader intellectual property enforcement actions against Chinese AI firms.
