Section 1
The big idea
AI writes one word at a time. For each word, it guesses which word is most likely to come next.
Some examples
- After 'peanut butter and...' AI strongly guesses 'jelly.'
- After 'I love...' the next word could be many things.
- Each guess is a probability, like a weather forecast.
- AI usually picks the highest one, but sometimes it explores.
Try it!
Type 'peanut butter and' to AI. Watch it pick 'jelly' (most of the time). Now type 'I love' — the answers will be very different each time.
