[counterintuitive] Should I always provide few-shot examples in prompts

Start with zero-shot instructions. Add few-shot examples only if the instruction alone fails to produce the exact format or reasoning style required, as few-shot can constrain the model to the examples' limitations.

Journey Context:
It is common practice to immediately add 3-5 examples. However, modern instruction-tuned models are highly capable of following zero-shot instructions. Few-shot examples can accidentally teach the model the wrong thing \(e.g., if the examples are too similar, the model might learn to mimic the similarity rather than the underlying task\), or limit the model's ability to generalize beyond the examples. Zero-shot often yields better reasoning on novel tasks.
