Prompting Without Training

Zero-shot vs Few-shot

One of the most powerful capabilities of LLMs is their ability to perform tasks they were never explicitly trained on, using only instructions or examples in the prompt.

Zero-shot Prompting

Give the model a task description with no examples. Works well for common tasks.

Few-shot Prompting

Provide 2-5 examples of input-output pairs before your actual query. The model learns the pattern from examples and applies it.

Best Practices

  • Use consistent formatting across all examples
  • Include edge cases in your examples
  • Order examples from simple to complex
  • Match the diversity of examples to your expected input distribution

Use Cases

Text classification without training data

Data extraction from unstructured text

Format conversion (JSON, CSV, etc.)

Translation between domain-specific formats

Common Mistakes

Using too many examples (>5) which wastes tokens without improving quality

Examples that contradict each other confuse the model

Not testing with zero-shot first — sometimes it works just as well
