My First Real Mental Model of LLMs

Dev.to Machine Learning

About This Tutorial

NOTE - I intentionally simplified the vector mathematics concept here to keep things simple for a greater audience. I wanted to learn LLMs properly. Not just use an API. I wanted to know how a model takes plain text, turns it into numbers, reads context, and predicts the next word. The end goal is ambitious: build a mini LLM from scratch. But before touching PyTorch, I realized I needed the mental model first. Code without understanding becomes copy-paste gymnastics. So I started with the real basics.
