Are Multimodal Benchmarks Really Useful? Item-Level Multimodal Benchmark Diagnosis via Structure-Response Co-Calibration
Multimodal benchmarks are central to evaluating whether models can reason over information from multiple modalities. However, existing literature has revealed that some benchmarks may contain shortcut items that can be answered from a single modality or from answer-option regularities alone, thus…
This article presents a new framework called SRCoD for diagnosing the effectiveness of multimodal benchmarks in AI models, addressing issues with existing benchmarks that may contain shortcut items.
What happened
The article introduces SRCoD, a new method for diagnosing the quality of multimodal benchmarks by analyzing both the structural content of items and model responses, aiming to identify and mitigate shortcut items that undermine the evaluation of cross-modal reasoning.
Why it matters
Effective multimodal benchmarks are essential for accurately assessing AI models' capabilities. SRCoD helps ensure that benchmarks are reliable, which is critical for advancing AI research and development.
- Multimodal benchmarks need rigorous evaluation to avoid shortcut items.

FAQ
What is SRCoD?
SRCoD is a structure-response co-calibrated diagnosis framework designed to evaluate the effectiveness of multimodal benchmarks by analyzing both the structural content of items and model responses.
Why are multimodal benchmarks important?
Multimodal benchmarks are crucial for assessing AI models' ability to reason across multiple data types, ensuring they can handle complex, real-world scenarios involving text, images, and other modalities.
What problem does SRCoD solve?
SRCoD addresses the issue of shortcut items in existing benchmarks, which can be answered without true cross-modal reasoning, thereby providing a more accurate evaluation of AI models.
