Nvidia Blackwell GPUs found in six Chinese AI models

will depue, a former openai researcher who worked on gpt-4o and sora, conducted a forensic analysis that found technical evidence of nvidia blackwell gpu usage in six chinese ai models. the models, from deepseek, moonshot ai, minimax, and ant group, show a distinct signature of nvidia's blackwell generation. depue's analysis estimates that the training runs required around 12,000 blackwell gpus, costing over half a billion dollars. this contradicts us export controls and suggests china's ai development may be more advanced than previously thought. the method used to detect the gpu fingerprints has been verified by senior researchers at openai and anthropic.
