About

OmniCompass evaluates MLLMs on temporal grounding, spatial grounding, and question answering using paired text and text+image specifications. It includes 820 videos across short, medium, and long durations, with a subset requiring audio-visual evidence.

Scoring uses Cross-Specification Consistency Scores to measure accuracy and consistency. Evaluations of 50 models show proprietary models outperform open-source ones, with top scores of 42.8% and 39.6% respectively.
