About

Content & Construction: SQUARE-Bench introduces a unified taxonomy of 38 sub-dimensions across Semantics, Quality, Authenticity, and Responsibility. It comprises nearly 10,000 curated AI-generated images from 22 diverse models plus over 3,000 real-world images, annotated with approximately 18,000 expert-driven question-answer pairs.

Scoring & Findings: The benchmark employs a dual-answer mechanism (Visual GT vs. Intended GT) to evaluate both LMM perception and T2I generation capabilities. Experiments on 23 Large Multimodal Models reveal that top proprietary models like Gemini-3-Pro outperform human experts, while open-source models occasionally surpass them in specific sub-dimensions.
