Interactive · the full journey
From your sentence to a prediction.
Pick a sentence and watch the same words travel all four steps, the trip your words make every time you talk to an AI.
Pick a sentence
I love eating apples in the morning ___
First, the sentence is chopped into the chunks the model recognises. A · marks a space inside a token.
Each meaningful word becomes a point in space. Tap one to see its nearest neighbours in this sentence.
Before writing the next word, the model checks which earlier words matter. Tap a word to see what it leans on.
Finally it ranks the next word and bets on one. Drag the temperature dial to see safe versus adventurous.
balanced
That is the whole trip. No thinking, no understanding the way you do it. Just chunks, coordinates, context, and a bet on the next word, repeated fast enough to feel like magic.
