That is an excellent explanation full of great intuition building!

If anyone is interested in a kind of tensor network-y diagrammatic notation for array programs (of which transformers and other deep neural nets are examples), I wrote a post recently that introduces a kind of "colorful" tensor network notation (where the colors correspond to axis names) and then uses it to describe self-attention and transformers. The actual circuitry to compute one round of self-attention is remarkably compact in this notation:

Here's the full section on transformers: https://math.tali.link/rainbow-array-algebra/#transformers -- for more context on this kind of notation and how it conceptualizes "arrays as functions" and "array programs as higher-order functional programming" you can check out https://math.tali.link/classical-array-algebra or skip to the named axis followup at https://math.tali.link/rainbow-array-algebra

This topic has been reposted few times recently, yet never gained much traction. I wonder how much changes there have been between GPT2 to GPT4?
