Alibaba Open-Sources Its Chip Software, Following Huawei And Moore Threads

T-Head's SAIL stack now runs Alibaba's Zhenwu chips, unveiled at WAIC Shanghai to loosen Nvidia's CUDA lock-in.

  • T-Head open-sourced SAIL, the software stack underpinning Alibaba's Zhenwu AI chips, on July 18.
  • The release came at WAIC, the World AI Conference, in Shanghai this week.
  • Huawei and Moore Threads previously open-sourced their own chip software to challenge CUDA.

Why it matters: Nvidia's real moat was never the chip; it was the software nobody wanted to rewrite around it.
