StudioWill Depue claims six Chinese AI models show fingerprints of training on export-banned NVIDIA Blackwell GPUs
Original title: I have a major result to share.
Will Depue claims conclusive forensic evidence that six Chinese open-weights models, including DeepSeek-V4-Pro, Kimi K3, and MiniMax-M3, were initialized on NVIDIA Blackwell chips barred from export to China. He matched over six trillion chip-layout and seed combinations against released weights, reproduced DeepSeek-V4-Flash's initial weights bit-for-bit on a B300 and Kimi K3's at 0.999995 correlation on a rented GB200, and estimates the largest runs used 2,000-3,000 Blackwell GPUs each. He says senior researchers at OpenAI and Anthropic independently verified the result.
The author presents a forensic method that identifies the training GPU from weight initialization fingerprints, backed by a six-trillion-combination search and real-hardware reproductions, letting readers audit the chain of evidence themselves.
