Comparison

Sampling vs Top-p

Sampling and Top-p are both common AI/LLM terms but cover different ideas. Here is a quick side-by-side.

When you would reach for Sampling

Sampling comes up when the question is fundamentally about inference.

OpenAI default: temperature 1.0, top-p 1.0.

When you would reach for Top-p

Top-p comes up when the question is fundamentally about inference.

top-p = 0.9: typical for chat assistants.

Frequently asked

What is the difference between Sampling and Top-p?

Sampling: Sampling is the act of choosing the next token from the model's output distribution, typically after applying temperature and a truncation strategy like top-p or top-k. Top-p: Top-p (nucleus sampling) restricts token selection to the smallest set of tokens whose cumulative probability reaches p. Common values are 0.9-0.95.

When should I use Sampling vs Top-p?

Sampling is the right concept when you are focused on inference. Top-p applies when you are focused on inference.

Are Sampling and Top-p the same thing?

No. Sampling is inference; Top-p is inference. They are related but address different parts of the AI stack.
