Multimodal RAG extends standard text RAG by retrieving from both image and text indexes using a joint embedding model like CLIP or ALIGN. The query - which may itself include an image - is embedded in the same vector space as the corpus items, enabling cross-modal similarity search. Retrieved image and text results are then fused (either late fusion via reciprocal rank fusion, or early fusion via concatenation and reranking) before being passed to a vision-language generator.
