Alibaba open-sourced SAIL, software that runs its Tianji AI chips, to build an independent ecosystem and reduce switching costs from NVIDIA's CUDA. The move mirrors similar efforts by Huawei (CANN) and other Chinese chipmakers, though experts expect ecosystem lock-in to CUDA will persist for years.

◆ ◆ The Wire takeaway
If you're building AI tools on CUDA, you now have a real alternative—but switching costs just dropped for anyone willing to bet on Chinese hardware. Alibaba is trying to do what took Google two years; watch which major labs actually port their work over the next 18 months, because that's when the real competition starts.
