[counterintuitive] Providing multiple examples \(few-shot\) is the best way to ensure format and accuracy

Default to zero-shot with clear instructions and structured output schemas; only use few-shot if the target distribution is highly non-standard or unintuitive.

Journey Context:
Few-shot was essential for GPT-3 and early GPT-4 to demonstrate the desired output format. With modern models, few-shot examples often constrain the model to the \*exact\* patterns in the examples, limiting its ability to generalize or use its stronger inherent capabilities. If an example has a subtle bug or suboptimal approach, modern models will eagerly replicate it \(imitation learning\). Structured outputs \(JSON schema\) and clear zero-shot instructions now outperform few-shot for standard tasks.
