Tiny Brain
Big AIs like ChatGPT have one job: guess the next word. Build a tiny one yourself and watch it count.
1 · Feed me
Type or paste sentences. The brain eats every word and remembers which word came after which.
0 different words · 0 sentences
2 · Next word?
Type a word (or two). The brain shows what usually came next, and how often.
3 · Let it talk
It writes 12 words, one at a time, always picking from its counts. The slider says how bold it is.
👉 It just picked from the counts. Every word. That is the whole trick.
Does that make sense?
It has no idea what the words MEAN. It only counted. With only a few sentences, every word has only one or two "next words", so it repeats, loops and mixes sentences up. Big AIs count trillions of words, so their guesses sound smart, but it is still counting.
4 · Experiment: 3 sentences vs 30
Does more food make a smarter brain? Note what it says now, then add 30 sentences about a school day and let it talk again.
Now scroll up and tap "Let it talk" again. More choices, fewer loops, but still no meaning.
The count table for "…" …
| next word | times seen | chance |
|---|---|---|
| type a word above | ||
chance = times seen ÷ total. That is the whole "prediction". The tiny brain stores 0 word pairs and 0 word triples right now.
