The Word Garden

Yagrumo chops a sentence into seeds, plants them in a garden of meaning, and grows fruit to guess the next word. Then he learns why an AI needs roots.

Real ideas, kid-sized.

Made by a data and AI team in San Juan. The ideas are the same ones we use to build AI for companies, explained so a seven-year-old can retell them at dinner.

  • How AI readsText is split into tokens, and each token becomes a number.
  • How AI understandsWords with similar meanings live close together on a map.
  • How AI writesIt guesses the next word from odds, one word at a time.
  • Why AI makes things upA confident answer isn't always a true one.
  • How AI learnsGuess, check the mistake, adjust, repeat.
  • How we fix itGood AI looks up real facts and shows where they came from.
