Jin Dive
When a language model predicts the next token, it produces a probability distribution over thousands of options. Greedy and top-k methods favor high-probability tokens, which can make text repetitive and bland. Typical sampling, introduced by Meister and colleagues in 2022, takes a different angle rooted in information theory. The model computes its expected information content (the entropy of the distribution). Tokens are then scored by how far their own surprisal sits from that expectation. Typical sampling keeps the set of tokens whose surprisal is closest to the average until their combined probability reaches a threshold, then samples from that set. The method favors tokens whose surprisal is closer to the distribution’s expected surprisal. It does not guarantee human-like wording, factual correctness, or coherence; evaluate outputs on the intended task.

What is Typical Sampling?
Typical sampling ranks candidate tokens by how close their surprisal is to the model distribution’s expected surprisal (entropy), then samples from a set reaching a chosen probability mass. This is a decoding heuristic, not a guarantee of human-like, factual, or coherent output.

Compared with greedy decoding, what does typical sampling try to change?
Typical sampling uses surprisal relative to entropy rather than simply choosing the most likely token.
