Up to 400 language and 400 vision attempts; Table 1 coverage varies from 385 to 400 and text-only models lack vision results. The available-task mean uses each model’s actual coverage. Whole-task success requires all stages and final gates. FP8, Preview and Code identities remain distinct. Rate (%).
