Would developers be able to easily run their code across all the different chips dotting the AI landscape? Lattner’s answer to that question is Modular, a software startup he founded in 2022 with his former Google colleague Tim Davis. As of this week, Modular’s developer platform now supports Apple Silicon GPUs, in addition to Nvidia and AMD chips. Nvidia’s chips make up the vast majority of the GPU market, but the company’s 20-year-old proprietary software platform, CUDA, keeps developers locked in. AMD’s software platform for high-performance computing, called ROCm, differs in that it’s open source.
