Report #45038

[counterintuitive] Providing 3-5 complex few-shot examples to teach a modern frontier model a new task format

Use zero-shot with structured output schemas \(JSON mode/tool use\) or detailed instructions; reserve few-shot only for highly nuanced stylistic alignment where zero-shot fails.

Journey Context:
Few-shot was essential for GPT-3 and early GPT-4 to demonstrate intent. With modern instruction-following and structured output capabilities, few-shot examples often consume context window, increase latency, and introduce conflicting edge cases when the examples slightly contradict the instructions. Models generalize better from explicit rules and schemas now; few-shot should be a fallback, not the default.
