This breakdown of the transformer architecture is super useful, especially seeing the encoder and decoder stacks mapped out so clearly. What really caught my attention is how you structured the pre-training implementation code alongside the theory. Most resources either go too abstract or dump code without context, but connecting the actual weight updates to the conceptual flow makes it way easier to debug when things go wrong. Have you noticed any particular bottlenecks in the training loop that beginners tend to miss?
