Expanding RAG Beyond Text
Multimodal RAG extends the retrieval-augmented generation paradigm to handle multiple data types — text, images, charts, tables, diagrams, audio, and video. Traditional RAG retrieves relevant text passages to ground AI responses; multimodal RAG retrieves and reasons over diverse content types, producing responses that reflect the full richness of organizational knowledge. This matters because enterprise information lives in slide decks, technical drawings, scanned documents, and videos — not just clean text.
Key Capabilities
The approach combines multimodal embedding models that can represent different content types in a shared vector space with vision-language models that can interpret and reason about visual content alongside text.
Implementation Approach
Multimodal RAG can answer questions by referencing charts and graphs in reports, extract information from tables embedded in documents, interpret technical diagrams and architectural drawings, summarize video content alongside related documentation, and combine insights from text and visual sources into coherent responses. This dramatically improves AI usefulness in domains where critical information is inherently visual.
