Learn how AI actually works. Then build it.
A free, complete course on AI engineering. Start with what a large language model really is, end with shipping production AI agents. 110+ structured lessons, runnable code, an in-browser playground. No setup. No paywall.
From first principles
to production systems.
Start with what AI actually is. Then how it learns. Then how it talks. Every lesson uses an everyday example first, then shows you the math and the runnable code. By the end you can read a research paper without flinching.
Deep Learning & Neural Networks
A stack of filters. Each layer transforms the input a little more abstractly than the last.
Build agents that
actually do things.
Modern AI doesn't just chat. It reads files, hits APIs, writes code, and ships work on its own. Build agents like that with Google ADK, OpenAI Agents SDK, CrewAI, AutoGen, and Claude — wired into GitHub, Slack, and your own systems through MCP.
Every lesson runs
live in the browser.
Skip the API keys, the install errors, the version mismatches. Open an in-browser playground from any lesson, edit the prompt, change the temperature, and watch the response stream back. Llama 3 70B is wired up today; Claude, GPT, and Gemini are next.

Three levels. One path.
110+ lessons that take you from "what is a token" to shipping production AI agents. Each level ends with a hands-on project. Self-paced. Always free.
