Study Proves Chinese AI Used Nvidia Chips

UnemploymentLabs researchers found statistical evidence that DeepSeek V4, Kimi K3.1, MiniMax-M3, and Ling-3.1-Flash models were trained using Nvidia Blackwell GPUs. The study analyzed 2,048 threads per shader module to match weight initialization patterns, confirming chip usage despite export controls. This finding suggests Chinese firms may have legally rented hardware abroad.
