Chinese AI Models Show Blackwell Chip Fingerprints
A forensic analysis by Will DePue, former OpenAI researcher, reveals that six AI models from Chinese labs DeepSeek, Moonshot, MiniMax, and Ant Group carry traces of Nvidia's Blackwell chips, which are banned for export to China. The analysis, based solely on model weights, identified the chip class used to generate initial values, estimating over $500 million in restricted hardware for final training runs. This evidence intensifies scrutiny of export controls and comes amid Nvidia CEO Jensen Huang's resignation following a spy affair scandal. The findings could pressure the open-weight model ecosystem, as many US startups rely on Chinese open models, and potentially impact companies integrating these models.
This article provides technical evidence that Chinese AI labs used banned Nvidia Blackwell chips, escalating export control tensions and potentially impacting the open-weight model ecosystem. It also comes at a critical time for Nvidia following CEO resignation.

Chinese AI Models Show Fingerprints of Banned Nvidia Chips
A forensic analysis by Will DePue of Unemployment Labs found that six new AI models from Chinese labs DeepSeek, Moonshot AI, MiniMax, and Ant Group carry fingerprints of Nvidia's Blackwell chips (B200/B300/GB200/GB300), which are banned for export to China. The analysis examined billions of parameter initialization patterns to infer the hardware used. Estimated GPU counts for final training runs range from 500 to 3,000 per model, implying hardware costs exceeding $500 million. The findings could intensify US export control scrutiny and pressure Nvidia's open-weight model strategy, especially after CEO Jensen Huang's resignation. However, the analysis does not prove ownership, location, or legal violations, and has not been peer-reviewed.
Nvidia Optimizes for Chinese Open AI Models
Nvidia said it is optimizing its hardware and software stack to support leading Chinese open AI models — including DeepSeek’s V4 Flash and Alibaba’s Qwen 3.8 — positioning its chips as the preferred infrastructure for developers worldwide. The company flagged business risks in an SEC filing tied to its second-quarter earnings, warning that potential White House restrictions on supporting third‑party applications or open-source models originating in China could materially affect its operations. The move comes amid growing U.S. lawmaker concern about the adoption and rising capabilities of Chinese models; other major tech companies previously urged policymakers to avoid premature restrictions on open-weight models.
Chinese AI Models Surge Globally, Washington Worried
Chinese AI models, including those from DeepSeek, Z.ai, and Alibaba, have seen a significant surge in global adoption during 2026, particularly on developer platforms OpenRouter and Vercel. On OpenRouter, Chinese models accounted for 57-67% of tokens used in the week of Sept. 14, up from 6-13% in February. On Vercel, their share reached 55% in August, up from 11% in January. This growth is driven by lower costs and improved performance, especially in coding and agentic tasks, though U.S. frontier models still attract more overall spending. The trend has drawn concern in Washington, with two House committees investigating the impact. Officials worry about security risks and Beijing's influence, especially as Chinese companies may access Nvidia chips remotely and use distillation techniques. Businesses in the 'Global South' are the heaviest users of Chinese models, with 67% of tokens used by these companies on OpenRouter.
