I have always admired @stevhliu’s work. I consider his technical writeups to be among the best there is.
In the latest series he covers how transformers loads a model. This might seem to be very simple, but there are a lot of moving parts involved which makes loading insanely fast.

If you want to know how a SoTA library’s core component works, I definitely recommend reading the blogs.
