Researchers have developed a new metric called the Perception-Fusion Gap to diagnose how multimodal GUI agents form beliefs about their interface state. This metric measures the extent to which an agent relies on visual pixels versus structured data (like DOM or accessibility trees) when encountering conflicting information. Across five models from three vendors, agents showed a tendency to favor structured data over pixel information, leading to errors in state belief and subsequent task failures. AI
