    About this course

    A clear, jargon-free picture of AI

    AI seems to think, reason, and understand. It's doing something far simpler — and far stranger. This module explains the real mechanism behind every AI response: read, learn patterns, predict.

    Once you see it, you can't unsee it. You'll understand why AI gets things confidently wrong, what a token is, and why the best users of AI are the ones who know the machine's limits.
