[counterintuitive] Adding more few-shot examples always improves model accuracy

Optimize for example quality and diversity over quantity; 3 highly relevant, distinct examples often outperform 10 noisy or redundant ones.

Journey Context:
Developers assume few-shot prompting is a linear curve where more examples equal better performance. However, too many examples can exceed context limits, dilute the model's attention, and introduce conflicting signals or formatting inconsistencies. The model can also overfit to the specific examples, losing its ability to generalize to the actual query.
