i created something similar a while back. Inspired by micrograd for showing the connection between math/calculus and code, then building along the way to a full NumPy deep learning library that I pretrained GPT-2 124M model with it. One way to learn is to trace through the PRs merged to the repo in chronological order. The philosophy is the same: "What I cannot create, I do not understand." https://github.com/workofart/ml-by-hand

My professor used this "by hand" technique when teaching quantum computation algorithms, so I have a soft spot for it.

This is also recommended reading if you want to learn more about building LLMs from scratch: See: Train your own LLM - https://github.com/angelos-p/llm-from-scratch HN Discussion - https://news.ycombinator.com/item?id=48017948

I’d say bad UX design. It may or may not be something good behind the door. But why do I enter?

I found Deep Learning by No Starch Press to be an excellent primer the foundation of AI: https://nostarch.com/deep-learning-visual-approach
