Definition and comparison boundarypublic methodology
Can the model accurately perceive visual evidence before reasoning or outside knowledge is required?
Three thousand verified questions spanning ten atomic visual-perception capabilities. Higher is better. The value is the percentage reported in this lab's table.
Harness, tools, prompts, attempt count, and benchmark version can materially change the result. Compare within one reporting context.
