Interactive AI tutorial for curious minds

Software engineer Rob Ennals wanted his 11-year-old son to understand how modern AI works, but couldn’t find a tutorial that was rigorous without being either hand-wavey or impenetrable. The result is Learn AI Layer by Layer, a free online book with interactive playgrounds in every chapter. It assumes middle-school math. If you want a clear, hands-on explanation of what happens inside an LLM, this is the best one I’ve come across. — MF
