[counterintuitive] Providing 3-5 examples \(few-shot\) is the best way to teach a model a new format or task

Use zero-shot instructions with native structured output/JSON mode; reserve few-shot only for subtle stylistic imitation that defies verbal description.

Journey Context:
Few-shot was essential for early instruction-following models. Now, models have robust instruction adherence and native schema enforcement. Few-shot examples consume massive context windows, increase latency, and risk overfitting to example quirks or typos. Zero-shot with schemas is more robust, token-efficient, and guarantees adherence without mimicry artifacts.
