According to former OpenAI researcher Will DePue on November 13, six AI models from DeepSeek, Moonshot AI, MiniMax, and Ant Group contain hardware fingerprints matching Nvidia Blackwell chips in their public weights. The models are DeepSeek-V4-Flash, DeepSeek-V4-Pro, Kimi K3, Kimi K3.1-Pro, MiniMax-M3, and Ling-3.1-flash. DePue's research identified GPU architecture and random seed patterns that match Blackwell systems, validated through testing with physical B300 chips.
Estimates suggest Kimi K3 and DeepSeek-V4-Pro each used approximately 2,000 to 3,000 Blackwell GPUs, with total estimated cluster costs of $150 million to $200 million per model. However, the research cannot determine whether chips entered China or if companies rented computing power from overseas data centers.
