[counterintuitive] Providing multiple few-shot examples is always better than zero-shot instructions for coding tasks

Use zero-shot with detailed guidelines for frontier models; only use few-shot if the output format is highly unintuitive and cannot be described structurally.

Journey Context:
Few-shot learning was essential for GPT-3 to demonstrate the desired output format. With modern instruction-tuned models, few-shot examples often anchor the model to the specific style, length, and even errors of the examples, overriding its broader capabilities. Zero-shot with clear structural instructions allows the model to use its maximum capacity and native reasoning without mimicking potentially flawed demonstrations.
