GPQA Diamond rank

Stored rank on the GPQA Diamond slice. 77 models store a rank, from 1 through 77 with no gaps. Rank 1 is Google: Gemini 4 Argon. Rank 77 is Google: Nano Banana 2 Lite (Gemini 3.1 Flash Lite Image). The number is that rank. A longer bar is a higher rank number, further down the board. This is not the accuracy and not the cost per task. A model with no stored rank stays off the page.
