Alibaba is releasing SAIL, a complete software stack for its in-house AI chips, directly attacking Nvidia's fifteen-year moat in developer lock-in. The constraint on chip competition isn't silicon anymore—it's the ecosystem. By open-sourcing rather than proprietary-walling its stack, Alibaba is betting it can convert its massive internal AI workloads into a reference architecture that other Chinese chipmakers and cloud providers can adopt, fragmenting Nvidia's control over the China market faster than hardware alone could. Software stacks are the actual switching cost; without SAIL, any non-Nvidia chip is just expensive silicon gathering dust in data centers.
