Welcome to How AI Works. It's for anyone who uses AI at work. You don't need a technical background.

It explains what's going on when a model answers you. It comes in four parts.

How it writes: one token at a time, picked from its odds. That's why the same request can come back different.

How it learned: what training gives it, why it sometimes makes things up, and why it tends to agree with you.

What it can see: only what the app sends it. That might be the chat so far, your documents, or an image.

And how it acts: with tools, it can look things up and take steps. And text it reads can try to give it orders.

Every recorded example in the course is a real model reply, labeled with the model and the date. Some are surprising. Asked how many r's are in strawberry, GPT-4.1 mini said two, all three times.

Each lesson goes one step at a time. You read a short part, see or try one thing, then move on. Each part ends with a short check.

First up: how a reply gets written.

16 lessons, a step at a time, with a short check after each module. No technical background needed. The recorded examples are real model replies, labeled with model and date. Module 1 is free, and the rest comes with Pro.
