What’s behind the door

• One guided path — from “what even is a model?” to building, evaluating, and operating real AI systems.
• 100+ lessons across ten path courses and two Go Deeper wings — leadership and model internals.
• Interactive demos in nearly every lesson — train a real model, watch an agent loop die and survive, step through RAG.
• Progress that follows you — mark lessons complete, resume anywhere, share a read-only view with a mentor.
• Self-paced, no cohorts — checkpoints with instant feedback and capstones you score yourself.

We store your email, an irreversibly-hashed password (none at all with Google/GitHub), and your lesson progress — nothing else. No tracking, no marketing, no sharing.
