Discover AI: open-source guide with 51 interactive labs for learning how AI works
Zipidyzip · reddit · 2026-10-21
The author released Discover AI, an open-source learning resource that breaks AI down into 51 hands-on labs across 6 groups — from neurons and gradient descent to attention, RAG, agents, fine-tuning, quantization, and serving.
Highlights:
- Every lesson comes in three reading levels (Simple / Plain / Standard), switchable anytime
- Some labs actually run rather than animate: the attention lab embeds a small trained 1.37M-param transformer, and training labs train a tiny character-level model live as you move sliders
- Fully offline, no account, no telemetry
Topics were hand-selected with verified sources (AI-assisted research); the author welcomes PRs and feedback from teachers and learners. GitHub link in the original post.
