U.S. BIS Advanced Computing Export Controls (Oct 2023)

The U.S. Bureau of Industry and Security expanded controls on advanced AI chips and semiconductor manufacturing equipment, prohibiting sales of GPUs exceeding performance thresholds to China. The rules targeted NVIDIA A100/H100-class chips and required licenses for any chip enabling large-scale AI training. This effectively cut off China's cloud providers and AI labs from the latest U.S.-designed accelerators.
