Summary

Kevin Xu’s (Interconnects) history of Chinese open source AI, from early contributions in the 2000s through DeepSeek’s 2025 open-weight release. Argues that China’s open-source AI moment isn’t a rupture — it’s the culmination of 20+ years of building.

Key Claims

  • China’s open source started quietly in the early 2000s; companies like Alibaba, Baidu, and Tencent became major OSS contributors by 2010s.
  • The inflection: DeepSeek’s open weights release was not just a technical achievement — it changed the geopolitics of AI.
  • Why Chinese labs open-source: access to global talent for improvements, learning from community bug reports, and strategic positioning against US export controls.
  • Export control response: open weights are harder to restrict than chips — releasing weights is both a technical and geopolitical maneuver.
  • The ecosystem effect: DeepSeek’s release spawned hundreds of fine-tuned variants globally within weeks.
