If that business makes it money selling a cross-platform AI inference engine, as was the case for my previous startup, it is bad business to tie yourself to single platform. I managed to build a single code base that would support CPUs, OpenCL, Metal, CUDA, D3D12, and WebGPU from a single set of kernel sources. As a single developer, there was no way I would have been able to, at the time, maintain separate code paths and GPU kernels for each of those platform, in addition to training the models etc.
