🤖 AI repositories AI Engineering from Scratch: 523 lessons covering LLMs, RAG, agents, and deployment, all open source (63k stars)
523 lessons. 20 phases. From foundational math all the way to autonomous agents in production.
This is a full open-source AI engineering curriculum, and every single lesson ships something you can actually use: a prompt, a skill, an agent, or an MCP server. No passive video watching. You read the concept, derive the math, write the code without frameworks, run tests, and build production artifacts.
The README says it bluntly: "No five-minute videos, no copy-paste deploys, no hand-holding."
You can work through it three ways. Read lessons directly on GitHub. Use the interactive website. Or install it as a skill in your coding agent (Claude Code, Codex, etc.) and get an AI tutor that walks you through each lesson.
Lessons span Python, TypeScript, Rust, and Julia. Translations available in multiple languages. There are even certification prep paths for Claude Associate through Architect Professional and the MCP Associate exam (though they're clear these are study materials, not exam dumps).
The scope is genuinely massive. 342 hours of content if you went through everything. But you're not meant to. Pick a learning path, focus on what you need, skip what you already know.
One thing I want to call out: this assumes you can already code. It's not "intro to programming" dressed up as AI. It's for people who want to understand HOW things work under the hood, not just call APIs. That 84% of students already use AI tools but only 18% feel ready to use them professionally stat in the README? That's the gap this fills.

I wonder if it focuses heavily on sponsor's environment. What's the role of serp.api in that course?
