Alibaba open-sources its AI chip software stack at WAIC, targeting Nvidia’s CUDA lock-in

TL;DR

Alibaba’s T-Head open-sourced SAIL, the software stack for its Zhenwu AI chips, at WAIC in Shanghai. It aims to lower the barrier to migrating off Nvidia’s CUDA.

Alibaba’s chip design unit T-Head announced at the World AI Conference in Shanghai on Saturday that it is open-sourcing SAIL, the full software stack for its Zhenwu series of AI chips. The move is designed to lower migration barriers for developers currently locked into Nvidia’s CUDA ecosystem. T-Head said programmers can adapt SAIL to mainstream AI frameworks in under seven days.

The vast majority of AI developers globally write software using CUDA, Nvidia’s proprietary toolkit for programming GPUs. That dependency effectively locks them into buying Nvidia hardware, a dynamic that has helped the company reach a $3.4 trillion market cap. Xi Jinping used the same conference on Friday to argue that no single country should monopolise AI, and T-Head’s open-sourcing of...
