What is Zero-shot prompting?

Zero-shot prompting is asking an AI model to do a task with no examples — just a clear instruction — relying on what it already knows.

Most everyday AI use is zero-shot: you state the task and the model does it from general knowledge, without you showing any sample answers. For common, well-understood tasks — summarise this, rewrite that, explain this simply — a clear zero-shot instruction is all a capable model needs.

The trade-off is control. With no examples, the model decides the format and style, which may not match what you had in mind. When the output keeps drifting from what you want, that's the signal to switch to few-shot prompting and show it an example or two instead of describing the target again.
