Concept

Zero-shot

Solving a task with no labelled examples, relying only on a natural-language instruction.

Definition

Zero-shot prompting asks a model to perform a task it has never seen labelled examples for, using only a description. Frontier LLMs are surprisingly capable zero-shot across classification, translation and reasoning, though few-shot examples typically lift accuracy further.

Common use cases

  • New domains
  • Rapid prototyping
  • Open-set classification
