Lesson 1 of 20
Your first AI lesson
A text AI is not looking up stored answers. It builds the sentence word by word, and at every step it only decides what comes next.
Four minutes on that one mechanism explains nearly everything that will surprise you later: why it makes things up, why it answers differently twice, and why two of your words change the lot.
