What is Top-p (Nucleus Sampling) in Applied AI?
A sampling strategy that keeps only the smallest set of next-token candidates whose cumulative probability passes a threshold p, then samples from that set. Top-p adapts to the model's confidence: when the model is sure the set is small, when it is unsure the set is larger. Compares to top-k, which fixes the candidate count.
Why Top-p (Nucleus Sampling) Matters for Your AI or Cybersecurity Career
Tuning top-p alongside temperature gives finer control over output quality than either alone. Production AI features almost always set explicit top-p values.
