MM-CRITIC：大型多模态模型作为多模态评判器的整体性评估

摘要

批判能力对模型实现自我提升并成为可靠AI助手至关重要。尽管在纯语言场景中已得到广泛研究，但大型多模态模型（LMM）在多模态批判方面的探索仍然不足——尽管它们在图像描述、视觉推理等任务中表现日益出色。本研究提出MM-CRITIC，一个从基础批判、修正批判与比较批判三个维度综合评估LMM批判能力的基准框架。该框架涵盖8类主要任务逾500项子任务，收集了不同参数规模LMM的4471份应答样本。为提升评估信度，我们融合专家知识构建标准答案评分体系，指导GPT-4o对模型应答进行标注并生成参考性批判意见，作为可信判断的基准锚点。大量实验验证了MM-CRITIC的有效性，并对主流LMM的多维批判能力展开全面评估。深入分析揭示了若干关键发现，包括应答质量与批判能力的关联性，以及不同评估维度下批判难度的差异性。代码已开源：https://github.com/MichealZeng0420/MM-Critic。

The ability of critique is vital for models to self-improve and serve as reliable AI assistants. While extensively studied in language-only settings, multimodal critique of Large Multimodal Models (LMMs) remains underexplored despite their growing capabilities in tasks like captioning and visual reasoning. In this work, we introduce MM-CRITIC, a holistic benchmark for evaluating the critique ability of LMMs across multiple dimensions: basic, correction, and comparison. Covering 8 main task types and over 500 tasks, MM-CRITIC collects responses from various LMMs with different model sizes and is composed of 4471 samples. To enhance the evaluation reliability, we integrate expert-informed ground answers into scoring rubrics that guide GPT-4o in annotating responses and generating reference critiques, which serve as anchors for trustworthy judgments. Extensive experiments validate the effectiveness of MM-CRITIC and provide a comprehensive assessment of leading LMMs' critique capabilities under multiple dimensions. Further analysis reveals some key insights, including the correlation between response quality and critique, and varying critique difficulty across evaluation dimensions.
