A White House official says China’s Moonshot company improperly obtained restricted Nvidia chips and accessed U.S. AI models while developing its Kimi K3 system, which drew attention last week for its advanced capabilities, according to reports. Bloomberg reports the official alleges Moonshot used access to U.S. AI models and Nvidia Corp. chips in a way that violated U.S. rules. The Japan Times similarly reports that the official claims Moonshot violated U.S. export control requirements and also breached terms of service in the process of building its product. While the accounts focus on the alleged use of banned or restricted Nvidia components and the sourcing or access of U.S. AI models, they do not provide detailed evidence or specific enforcement actions in the summaries. The claims add to ongoing scrutiny of how foreign companies source high-end semiconductors and AI technology subject to U.S. restrictions. Moonshot’s and Nvidia’s responses are not described in the provided excerpts.
