[counterintuitive] Providing multiple complex few-shot examples to teach a modern frontier model a standard task format

Use zero-shot instructions with strict structural schemas, reserving few-shot only for highly non-standard or idiosyncratic output formats.

Journey Context:
Few-shot was essential for GPT-3/3.5 to demonstrate the desired output format. With modern models, they generalize zero-shot instructions perfectly. Few-shot examples often introduce bias, consume massive token limits, and if the examples have subtle differences, they confuse the model. Zero-shot with a clear JSON schema or output format is more reliable, cheaper, and avoids the 'distractor' effect where the model blindly copies the structure of a mediocre example rather than solving the actual problem.
