LAB 02 / PREDICTION & SAMPLING

The model doesn't know the next word. It guesses.

Pick a prompt below, then adjust temperature, top-K and top-P to see how the next-token distribution changes.

Probability distribution
At each step, the model doesn't just pick a word. It calculates how likely every possible next word is (the bars below). A word is then chosen based on those odds. This is called sampling.
Temperature
Controls how safe or adventurous that choice is. Low temperature makes the model almost always pick the single most likely word: predictable, sometimes repetitive. High temperature makes it more willing to pick less-likely words: more varied, but riskier.
Top-K
Instead of considering every possible word, only look at the K most likely ones, then choose among just those. A small K (e.g. 3) keeps output focused; turning it off considers everything.
Top-P (nucleus sampling)
Instead of a fixed count, keep adding the next most likely words until their combined probability reaches P (e.g. 90%), then choose among that group. It adapts automatically: a small group when the model is confident, a bigger one when it's unsure.
