US export controls

Regulatory framework implemented by the United States to restrict the transfer of advanced semiconductor technology and AI hardware to strategic competitors, specifically targeting China.

Key Impacts

Impact on LLM Development:
- Delays in deepseek R2 development attributed to hardware-related performance issues and supply constraints.
- Scarcity of nvidia H20 chips directly linked to US export controls.
Hardware Limitations:
- Restrictions on high-end GPU availability are creating bottlenecks in the training of large-scale models within restricted jurisdictions.
