China’s Lunar AI Used Banned Nvidia Chips, US Official Alleges

A senior U.S. government official has leveled accusations against Chinese AI firm Moonshot AI, alleging that the company has circumvented export controls to gain access to advanced Nvidia chips, crucial for cutting-edge artificial intelligence development. This accusation comes on the heels of Moonshot AI’s unveiling of its Kimi K3 model, a sophisticated large language model that has demonstrated a notable reduction in performance disparity compared to leading global offerings such as Anthropic’s Fable 5 and OpenAI’s GPT 5.6 Sol, even outperforming them in specific benchmark tests.

The Kimi K3 model, lauded as the largest open-source model to date with a staggering 2.8 trillion parameters, represents a significant leap in the capabilities of Chinese AI development. However, a statement released by Michael Kratsios, Director of the White House Office of Science and Technology Policy, on Wednesday, asserted that Moonshot AI has “acquired GB300-equipped servers and has accessed GB300s in Thailand, likely to train its AI models.” The GB300 represents a generation of Nvidia’s AI accelerators that, while not the absolute latest, are still considered highly advanced and are subject to U.S. export restrictions to China.

This development underscores the escalating technological competition between the United States and China in the domain of artificial intelligence. The U.S. has been implementing stringent export controls on high-performance AI chips, aiming to limit China’s access to hardware that could propel its AI ambitions and potentially be used for military or advanced surveillance applications. The accusations against Moonshot AI suggest a determined effort by Chinese firms to circumvent these restrictions, potentially through offshore acquisition and access points.

Nvidia’s most advanced AI chips, designed to accelerate the complex computations required for training and deploying sophisticated AI models, are at the forefront of this geopolitical technological contest. While some less powerful semiconductors are permitted for export, the most capable ones are strictly controlled. The GB300 chips, a step behind Nvidia’s absolute frontier systems like its Vera Rubin platform, still represent a significant technological advantage.

The controversy surrounding Moonshot AI’s alleged chip access coincides with a period of heightened AI rivalry between the U.S. and China. Beyond hardware restrictions, U.S. policymakers are increasingly scrutinizing the adoption of Chinese AI models by Western businesses, concerned about potential data security risks and intellectual property concerns. Reports have also emerged of Chinese tech giants actively seeking to build substantial computing power outside of China to bolster their AI research and development efforts. For instance, a March report indicated that ByteDance was exploring such avenues, highlighting the global nature of this technological pursuit.
