FindIt - Single-Label Object Detection: leaderboard

Single-label object detection: the model returns boxes for every instance of one named category in images from Pascal VOC, OpenImages and iGround. FindIt (2026), a format-informed localization benchmark for multimodal LLMs, scores each model with the bounding-box and output format it handles best, as F1 at IoU 0.5 averaged over the datasets, in percent; higher is better.

Metric: Average F1@0.5 (%) over single-label object detection (all instances of one named category) on 1,000-query subsets of Pascal VOC, OpenImages and iGround; each model scored with the box representation, text or JSON output and JSON key that a two-stage probe on Pascal VOC found best for it; boxes Hungarian-matched to the ground truth, a match counts at IoU 0.5 or more (with the right label for multi-label queries); unparseable outputs count as empty; higher is better.
