Top-p (Nucleus Sampling)

Top-p, or nucleus sampling, is a decoding method that limits generation to the smallest set of tokens whose cumulative probability is below a chosen threshold. Instead of a hard cutoff by rank, it filters by probability mass, producing coherent yet varied outputs. For practitioners, top-p is a nuanced control for creativity in Ai Messages, used alongside temperature to fine-tune style, safety, and predictability. Top-p, or nucleus sampling, limits generation to the smallest set of tokens whose cumulative probability mass stays below a chosen threshold. Instead of cutting off by rank, it filters by likelihood, producing coherent yet diverse responses. For AI messaging systems, adjusting top-p works alongside temperature to fine-tune creativity, safety, and stylistic variation in outputs.
