OMD-Bench (Synthetic, CoT) - Abstention Calibration Error: leaderboard
Metric: Abstention calibration error (%): the mean over corruption levels k=0 to 3 of the absolute gap between the model's abstention rate and the human-annotated rate (near 0 up to k=2, near 98 at k=3), on the synthetic split (generated video and audio with human-written text) of OMD-Bench (255 knowledge questions about 27 anchors, objects or events shown at once in video, audio and text; five options including an explicit abstention; unparseable answers are excluded), chain-of-thought prompting; lower is better. Source: arxiv.org. Saturation forecast: Around January 2027. 10 models tracked.
