[counterintuitive] Providing 3-5 examples to teach a model a new output format or task structure

Use zero-shot with structured output schemas \(JSON mode\) and explicit instructions; reserve few-shot only for highly nuanced stylistic imitation that resists formal specification.

Journey Context:
Few-shot was essential when models couldn't follow zero-shot instructions well. Now, few-shot examples often conflict with each other or with the system prompt, and they consume context window without guaranteeing adherence. JSON schema enforcement \(Structured Outputs\) is 100% reliable for format, making few-shot format examples obsolete and fragile.
