# From Using AI to Building With It: A Developer’s Learning Path

*Everyone uses AI now. Far fewer can actually build with it. Here’s the path between the two — and the order that makes it click.*

There’s a strange gap in software right now. Almost every developer uses AI daily — autocomplete, a chat window, pasting an error and hoping. But there’s a wide difference between *using* AI and being able to *build* with it: to extend your own tools, wire models into products, and know when the output is quietly wrong.

I kept meeting developers stuck on the near side of that gap, unsure what to learn next. And when I went looking for a map, I mostly found “AI engineer” roadmaps aimed at ML researchers — matrices and gradient descent — not at working developers who just want to *ship*.

So here’s the path I actually wish I’d had, in the order that makes each step build on the last.

## Foundations — how the model works

Not the math, but the mental model: tokens, the context window, why it hallucinates, what a transformer actually does. You can’t push a tool past where you understand it, and most “AI is dumb” complaints are really “I didn’t understand the tool.” An hour with Karpathy’s *Intro to LLMs* and 3Blue1Brown’s transformer videos pays for itself many times over.
