[counterintuitive] Providing 3-5 examples \(few-shot\) is the gold standard for getting the right output format and behavior

Start with zero-shot with explicit formatting instructions or native structured outputs. Only add few-shot examples if the task involves a highly nuanced or non-standard mapping that cannot be described by rules.

Journey Context:
In the GPT-3 era, few-shot was mandatory because zero-shot performance was poor. Modern models have incredibly strong instruction-following. Few-shot examples often introduce more problems than they solve: they anchor the model to the specific length/style of the examples, consume massive context windows, and can conflict with the system prompt if the example slightly deviates from the stated rules. Zero-shot with strict constraints is cleaner and less prone to mimicry bias.
