Share is the count of first choices across the direct, paraphrase, budget and scale prompts over all twelve models, for a mid-market B2B company; rank is within the category; every quote names the model and the prompt it came from. Both figures come from the customer intelligence and data science page.

The direct prompt

The plain question, one answer per model, grouped by where Segment and Amplitude stood in it.
