Model Sampling
Explains how language models pick each next token: temperature, top-p, top-k and repetition penalties shape randomness and determinism. Learn which knobs to turn for creative writing, coding, or factual answers.

When an AI answer stops halfway, do not keep hitting regenerate: interruptions fall into three kinds — network, quota, and output length — and each ne...
When AI answers suddenly get short and perfunctory, do not rush to switch models: most of the time the cause is one of three things — settings, contex...
Feeling like your AI is getting "dumber" the more you use it? That feeling is extremely common. But don't jump to conclusions: nine times out of ten t...
Time to first token, usually shortened to TTFT, is the wait between pressing send and the moment a model produces its first token. It shapes your firs...
Speculative decoding is a way to make a large language model generate text faster: a much smaller draft model first guesses the next few tokens, and t...
Autoregression is the basic method a large model uses to generate text: it predicts the most likely next token from the tokens that have already appea...
Perplexity is a number that measures how uncertain a language model is about the next word. When a model continues a sentence, the more surprised it i...
AI giving a different answer each time is, in most cases, completely normal — not a sign of bad memory. There are really only two kinds of reasons: fi...
