[counterintuitive] Using few-shot examples as the primary way to define output format or task behavior

Use zero-shot with explicit schema definitions \(JSON mode/Structured Outputs\) or detailed instructions first. Only add few-shot examples if the task has irreducible ambiguity in edge cases.

Journey Context:
Few-shot was essential for GPT-3/3.5 to understand intent. With modern models, few-shot examples often anchor the model too heavily to the specific examples, reducing its ability to generalize or follow complex explicit instructions that contradict the examples slightly. It also consumes massive context window. Zero-shot with strict schemas \(like OpenAI Structured Outputs or Anthropic tool use\) is far more reliable, deterministic, and token-efficient.
