Does anyone have good resources into a more practical approach toward building diffusion models? I found the book by Rashka for Building an LLM from Scratch really helpful in understanding a lot of concepts behind LLMs, and I am looking for a similar resource for diffusion models

MIT's OCW is usually pretty reliable:

There is more math-heavy https://diffusion.csail.mit.edu/2026/index.html

I really liked Calvin Lou’s tutorial. It’s quite old at this point and probably not up to date, but I felt it was awesome for understanding the concepts
