Dropped

Models ground many objects at once by outputting boxes for named categories in LVIS images.

Seed built this multi-object grounding set from LVIS for the Seed1.5-VL report. The report compares it with detectors such as Grounding DINO.

Seed1.5-VL leads with 72.5%

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.
