What is this?
Zero-shot means you give instructions and input with no solved examples. The model relies on pretraining and your wording alone.
Why should you care?
PromptVerse uses zero-shot for simple intent labels when you have no labeled examples yet.
See it live — copy this example
Copy the prompt into ChatGPT, Claude, or your LLM API playground and compare outputs.
Classify sentiment as positive, neutral, or negative.
Text: "PromptVerse cut our ticket backlog in half."
Reply with one word only.What happened?
- No prior input/output pairs appear.
- The task name and constraint "one word only" steer format without examples.
Practice next
- Try zero-shot on 5 support snippets.
- Note mislabels.
- Add output constraint "JSON only".
- Change to 3-class → 5-class sentiment.
- Add definition line per class.
Remember
Zero-shot = no examples in prompt. Good for quick baselines. Add shots when accuracy stalls.
Cold start classifier
New tenant has no labeled tickets.
Outcome: Zero-shot routing works for obvious cases until few-shot data exists.
