Open the box. Then build with what is inside.
Start here. This is the course everything else on this page assumes: what a language model is really doing, in order, from a sentence becoming tokens to a fine-tuned model serving requests. Every chapter is short, every chapter ends with something running on your own machine, and none of it costs anything. If you only ever take one course from us, take this one.

Who this is for
- Anyone who wants to understand these models rather than just use them
- Students who want a foundation that outlasts whichever tool is popular this year
- Developers who can read code and are tired of hand-waving explanations
- Career-switchers who need one solid, provable base to build on
Anyone who wants to use AI without touching code — Claude at Work is the course for that, and it needs no programming at all.
Prerequisites
- Basic Python — loops, functions, and installing a package.
No maths beyond school level, and no machine-learning background. Every chapter starts from working code you can run, so you learn by changing something that already runs rather than by staring at a blank file.

What you walk away with
- A genuine understanding of how these models work, not a vocabulary list
- Your own fine-tuned model, measurably better than its starting point
- A deployed application you built, running on a URL
- Every chapter's code, yours to keep and reuse
- Codnov Certificate of Completion, with a unique ID and a public verification link
Sample projects
- A classifier for a task that matters to you, fine-tuned on your own data
- A question-answering assistant over documents you already own
- A model with tools, doing something a plain prompt cannot
- A deployed API serving your own model at a cost you have measured
You finish with a deployed, reviewed AI project, or we re-run you free.
