This is a pretty phenomenal article.

Even for those who don’t care about LLM use, this is just a great article on optimizing Swift performance, which is sadly something that doesn’t have a lot of written material for.

I’m curious if the AMX instructions are truly secret. In theory you could use an M4 or above and get them via SME I think but I’m just guessing as I’ve never tried intrinsic from Swift myself.
