Hands-on AI Engineering

Theory you read, code you run. Every lesson pairs writing with a live sandbox that calls real AI models — securely proxied, so no API keys ever touch the browser.

Live sandboxes

The sandbox is the lesson.

No copy-pasting into a scratch project. You edit real code in the browser, it hits our secure proxy, and a live model answers — token by token.

  • Keys stay server-side — the proxy injects them.
  • Streaming responses, just like production.
  • Validate your output to unlock the next lesson.

const res = await fetch(PROXY_URL + "/api/sandbox-proxy", {

The curriculum

Six modules, zero fluff

From your first API call to a monitored, evaluated agent in production.

Learning that runs

No slides, no throwaway snippets. Each step is a working sandbox.

Read & write

Short theory, then you edit real code in an in-browser editor.

Run for real

Your code hits our secure proxy and calls a live AI model.

Validate to advance

We check your output and unlock the next lesson.
