On the corp side you have FB w/ PyTorch, xformers (still pretty iffy on AMD support tbt) and MS w/ DeepSpeed. But let's see about some others:

Flash Attention: academia, 2y behind for AMD support

bitsandbytes: academia, 2y behind for AMD support

Marlin: academia, no AMD support

FlashInfer: acadedmia/startup, no AMD

ThunderKittens: academia, no AMD support

DeepGEMM, DeepEP, FlashMLA: ofc, nothing from China supports AMD

Without the long tail AMD will continue to always be in a position where they have to scramble to try to add second tier support years later themselves, while Nvidia continues to get all the latest and greatest for free.

This is just off the top of my head on the LLM side where I'm focused on, btw. Whenever I look at image/video it's even more grim.

Modular says Max/Mojo will change this and make refactoring between different vendors (and different lines of the same vendor) less of a showstopper but tbd for now

The judge is still out there regarding if Max/Mojo is going to be something that the large majority cares about.
