Researchers have developed C$^3$PO, a new benchmark designed to evaluate the cross-modal reasoning capabilities of omnimodal models. This benchmark, comprising 3,404 samples across video, audio, image, and text, specifically tests a model's ability to compose information from different modalities and resolve deliberate contradictions. The study found that while humans achieve high accuracy, even advanced models like Gemini-3.1 Pro struggle, with a significant portion of failures attributed to modality dominance where models prioritize one input type over others, particularly text.
