The full path from vectors to your own language model.
Sixteen modules. Math derived from first principles. Code labs you can run in your browser. A locked door at the end of every module — solve the math, the door opens, a new tool appears in your kit. By Module 16 you've shipped a paper.

01Pick your flavor
Each flavor reshapes the side quests, examples, and cosmetic theme. Pick the one that fits you best — you can switch any time.
02Pick your primary language
Every code lab ships in multiple languages with a slider. This sets which one opens by default. You can switch per-lab any time. T0/T1 run in your browser; T2/T4 link out to a sandbox; downloads always work.
