Report #63663

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

Use zero-shot with explicit structural constraints and output schemas first; only add few-shot examples if the task involves subtle stylistic nuance that defies formal description.

Journey Context:
Few-shot was essential for GPT-3 davinci to understand intent. With modern instruction-tuned models, few-shot examples often conflict with the system prompt or constrain the model to the exact distribution of the examples, limiting generalization \(anchoring bias\). Zero-shot with strict schema enforcement leverages the model's instruction-following capabilities without anchoring it to a few potentially unrepresentative examples.
