Most of the time when upgrading models we have needed to change prompts to get the same performance (let alone better performance). Usually, your prompt is overfit to the specific model doing the specific task. For example often your previous prompt is overspecifying and creating contradictions that a dumber model would just gloss over whereas a smarter model will try even harder to follow.

Here is an example of a guide from OpenAI on how you should prompt 5.6 differently than their previous models.

Thanks, I was looking for something like that
