[cost\_intel] Adding few-shot examples to reasoning models degrades performance and wastes tokens
Use zero-shot instructions for reasoning models; reserve few-shot prompting for GPT-4o
Journey Context:
Developers waste tokens on few-shot examples with o1, but reasoning models are trained to think from first principles. The reasoning guide notes few-shot examples often provide no benefit versus zero-shot, as the model prioritizes its internal chain over example patterns.
