Expanding RAG beyond just text allows systems to work with images, audio, and other types of content. This creates more versatile and powerful applications:

Connecting Different Content Types:

  • CLIP: A system that understands both images and text in the same way, letting you search for images using words or find text related to images
  • ImageBind: Takes this further by connecting six different types of content (like text, images, audio) in a unified way
  • LLaVA/GPT-4V: Advanced systems that can look at images and understand them in context with text

Unified Storage Approach:

  • Creates a single storage system where different types of content (text, images, etc.) can be searched together
  • Allows searching across different content types with consistent results (like finding images related to text queries)
  • Supports documents that mix text, images, and other media while keeping their relationships intact

Processing Mixed-Media Documents:

  • Extracts text from visual elements like charts, graphs, and diagrams
  • Creates text descriptions of visual content so it can be searched and understood by the system
  • Preserves important relationships between text and nearby images or graphics

Creating Rich Responses:

  • Generates answers that include both text and relevant visuals when appropriate
  • Selects helpful images or diagrams to better explain concepts
  • Creates charts or visualizations based on retrieved information to make it easier to understand

These multimodal capabilities make RAG systems 40-60% more effective in fields that rely heavily on visual information, such as medicine, design, scientific research, and media content.
