Seeing Through the MiRAGE: Evaluating Multimodal Retrieval Augmented Generation

arXiv:2510.24870v2 Announce Type: replace Abstract: We introduce MiRAGE, an evaluation framework for retrieval-augmented generation (RAG) from multimodal sources. As audiovisual media becomes a prevalent source of information online, it is essential for RAG systems to integrate information from these sources into generation. However, existing evaluations for RAG are text-centric, limiting their applicability to multimodal settings. MiRAGE is a claim-centric approach to multimodal RAG evaluation, consisting of InfoF1, which assesses factuality and information coverage, and CiteF1, which assesse

Why this matters
Why now

As AI models advance, the need to integrate and accurately evaluate their performance on multimodal data, especially retrieval-augmented generation, is becoming critical for effective deployment.

Why it’s important

Evaluating multimodal RAG is crucial for ensuring factuality, information coverage, and proper citation in AI systems that handle diverse data types like audiovisual media, moving beyond current text-centric limitations.

What changes

The introduction of MiRAGE provides a standardized framework for assessing multimodal RAG, enabling more rigorous development and deployment of advanced AI applications.
