AVTrace - Cat1 Minimal-span Grounding - Acc@0.5s: leaderboard
AVTrace Cat1: Minimal-span temporal grounding, measured by Acc@0.5s (0–1) over 1,000 test questions. Five off-the-shelf omni-model runs use greedy decoding with 512 new tokens; source-native interfaces expose full clips, sampled frames/audio, or only 30 seconds depending on the model. A reference-blind Qwen3.5-27B normalizes answers before deterministic scoring against partly model-assisted silver references. Invalid answers receive zero; exact checkpoint revisions remain unreported.
Metric: Acc@0.5s (0–1). Source: arxiv.org. Saturation forecast: Rough model projection: around 2026. 5 models tracked.
