Data

top-p

Top-p (nucleus) sampling keeps the smallest set of tokens whose cumulative probability exceeds p.

Expanded definition

top-p shows up constantly when teams ship LLM features. Practically, it influences how you design prompts, evaluate quality, and reason about failure modes. Teams should document how top-p manifests in their stack—data handling, evaluation, and runtime guardrails—and revisit assumptions as models update.
