Only Gemini 3.1 Flash Image (nano-banana-2, Web Search) has a rating here, from its lab’s own post
Best score per model as labs report them in their own cards. Labs pick their own settings, so these compare less cleanly than independent runs. A rating ranks a model only against others rated in the same arena at the same time, so these don’t show who leads.
Bars start at 1,025.05.

Scores over time
All the scores we have, one dot each, so a model tested at several settings appears more than once.
