Episode notes
Export Controls Target Compute Bottlenecks
- The U.S. export controls targeted semiconductor manufacturing equipment and advanced AI chips as a national security measure.
- The H100 was banned but NVIDIA produced a downgraded H20 that remained legal and useful for inference tasks.
The Needle: Hurt Progress Without Spurring Indigenization
- The export-control strategy tried to balance harming China’s AI progress while avoiding incentives for indigenization.
- Evidence suggests China remained compute-constrained and the controls materially slowed its frontier AI work.
Policy Flip On The H20 Chip
- The Trump administration initially tightened rules on H20 exports but then reversed to allow sales under new terms.
- That reversal set the stage for the reported 15% revenue arrangement with NVIDIA and AMD.
