[Research Finds Numerical Characteristics of Nvidia Restricted Chips in Models from Four Chinese AI Labs] Unemployment Labs analysis of publicly available model weights revealed that six AI models from DeepSeek, Dark Side of the Moon, MiniMax, and Ant Group exhibit numerical characteristics of Nvidia Blackwell chips. The US has imposed export restrictions on this series of chips to China.
The research involved models such as the DeepSeek V4 series and Dark Side of the Moon Kimi K3. Researchers stated that traces in the weights support the use of these chips for model training, but cannot prove that the hardware was used throughout the training process, nor can they determine the chip's location, acquisition method, or whether it violated export controls.
