And what makes you so confident that all those people are using different prompt styles when comparing models? You think most people don’t even understand the bare basics of how to compare two products?
They might complain that GPT-4 is rubbish in comparison to Claude, but someone with a different personal prompting style might experience the opposite.
And given that those are tools, it's more like "the model can work with the user's prompts" rather than "the user's prompts are adapted to the model".
Unless we're here for an ego trip.
