Teaching the AI a task by showing it a handful of examples, right in the prompt.
Instead of describing what you want, you SHOW the AI what you want. You put 2-5 examples of the input-output pattern at the start of your prompt, then ask it to continue the pattern for a new input. The model picks up the shape, style, and rules from your examples without any training.
Few-shot is a superpower for edge cases and domain-specific outputs. When a plain description isn't enough, examples fix it fast. No code, no training - just add a few sample inputs and outputs to the prompt.
