Tap a word, watch the model rank it

no code · fully interactive · the whole stack

Understand how modern LLMs actually work, by building intuition, not watching videos.

One connected arc, from “a word is a vector” through attention, transformers, scaling, RAG and agents, down to the GPUs underneath. Every lesson opens with a wall you can feel, then hands you the tool that breaks it.
