Metaplane vs Monte Carlo

Twelve of fourteen models named Metaplane first on the direct prompt; two named Monte Carlo. Metaplane was named by thirteen of the fourteen models and Monte Carlo by fourteen and Metaplane carries 39 labels and Monte Carlo 53, so the shares are not directly comparable.

Share is the count of first choices across the direct, paraphrase, budget and scale prompts over all fourteen 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 data quality and observability page.

By framing

How many of the fourteen models made each the first choice, per way of asking, and how many argued against it.
