You might already be advanced beyond high-level introductory material, but this short book chapter by Chris Lattner himself was a good read for me (a casual reader, not a compiler expert).<p><a href="http://aosabook.org/en/llvm.html" rel="nofollow">http://aosabook.org/en/llvm.html</a>

At the expense of sounding crazy, I'd actually recommend ChatGPT to help you learn this. Ask it pointed questions and keep going down that path. Don't ask it for code but ask it to explain things to you. it's really useful that way and avoids the meme-worthy bad code.
"Transformers for Natural Language Processing" by Denis Rothman on Packt is a good one.<p>Make sure to get the 2nd edition for the coverage of newer models, particularly the ones from Hugging Face.<p>Everything I've read from Denis is really good. He's great at explaining complex topics in ways that are straightforward and digestible.
