A US House committee chair alleges Nvidia provided extensive technical assistance to Chinese AI startup DeepSeek, helping achieve breakthrough training efficiency with just 2.788M H800 GPU hours. Documents suggest the AI models were later used by China's military, intensifying debate over US export controls and national security risks in the AI race with Beijing.

Nvidia Technical Assistance Under Congressional Scrutiny

Nvidia DeepSeek has become the center of a heated controversy after Representative John Moolenaar, a Michigan Republican who chairs the House Select Committee on China, sent a letter to U.S. Commerce Secretary Howard Lutnick alleging that the chipmaker provided extensive technical support to the Chinese AI startup

. According to documents obtained by the committee from Nvidia, the company's technology development personnel helped DeepSeek achieve major training efficiency gains through an "optimized co-design of algorithms, frameworks, and hardware"

3

. Internal Nvidia reporting reportedly boasted that DeepSeek-V3 requires only 2.788M H800 GPU hours for its full training—significantly less than what U.S. developers typically require for frontier-scale models

AI Models Used by China's Military Raise National Security Concerns

The controversy intensified with claims that these AI models were later used by China's military, raising serious national security concerns in Washington

. The documents cover Nvidia activities from 2024, and Moolenaar acknowledged that at the time Nvidia provided DeepSeek help, there was no public indication that DeepSeek's technology was being used by China's military

2

. "Nvidia treated DeepSeek accordingly - as a legitimate commercial partner deserving of standard technical support," Moolenaar wrote in the letter

3

. DeepSeek shook markets early last year with a set of artificial intelligence models that rivaled some of the best offerings from the United States but were developed with far less computing power, fueling concerns that China could catch up with the U.S. in the AI race despite U.S. chip export restrictions

Nvidia Pushes Back on Military Dependence Claims

In a forceful response, Nvidia said it would be "nonsensical" for China military AI operations to depend on American technology

1

. "China has more than enough domestic chips for all of its military applications, with millions to spare. Just like it would be nonsensical for the American military to use Chinese technology, it makes no sense for the Chinese military to depend on American technology," the company stated

2

. Nvidia further argued that "The Administration's critics are unintentionally promoting the interests of foreign competitors--America should always want its industry to compete for vetted and approved commercial businesses, and thereby protecting national security, creating American jobs, and keeping America's lead in AI"

1

. The company's statement did not directly address the specific allegations of Nvidia technical assistance or the claims about training AI models using H800 chips

US Export Controls and H200 Chip Sales Fuel Debate

The allegations come at a critical moment as U.S. President Donald Trump's administration recently approved sales of Nvidia's H200 chip to China with restrictions, including that the chips not be sold to entities that assist the Chinese military

2

. The H200 is more powerful than the H800 chips DeepSeek used for training

3

. Trump's decision drew fire from China hawks across the U.S. political spectrum over concerns the chips would supercharge Beijing's military and erode the U.S. advantage in AI

2

. Nvidia's H800 chip was specifically designed for the China market and sold there before H800 chips were put under US export controls in 2023

2

. Under the new framework, Chinese buyers must show they have adequate security measures in place and formally confirm that the chips will not be used for military applications

Licensing Restrictions and Future Implications

Moolenaar warned that "If even the world's most valuable company cannot rule out the military use of its products when sold to (Chinese) entities, rigorous licensing restrictions and enforcement are essential to prevent such assurances from becoming superficial formalities"

3

. He added that "Chips sales to ostensibly non military end users in China will inevitably result in a violation of the military end use restrictions". China's embassy in Washington criticized the allegations, with spokesperson Liu Pengyu stating that "China has all along opposed moves to overstretch the concept of national security or politicize trade and tech issues"

3

. The U.S. Commerce Department did not immediately respond to requests for comment, while DeepSeek did not respond outside business hours in China

2

. This controversy highlights the complex challenge facing policymakers as they balance commercial interests with national security in an era where hardware and computing power determine leadership in the global AI race.
