๐ What Youโll Learn
โ What is Vision RAG?
Discover how Vision RAG fuses state-of-the-art text ๐ and image ๐ผ๏ธ processing into one powerful workflow.
No more text-only limits!
โก Step-by-Step Setup
Get up and running fast: requirements, environment configuration, and database setup using Docker ๐ณ & PostgreSQL ๐ with pgvector ๐งฉ.
๐ฅ Ingestion Pipeline
Watch Vision RAG extract, chunk, and embed both text & images (OpenAI ๐ค + Cohere ๐) โ then store them for lightning-fast semantic search. โก
๐ Powerful Multimodal Search
See queries instantly retrieve relevant passages and visuals from docs, research papers, manuals, and more! ๐ฅ
๐ก Contextual, Multimodal Answers
Watch Vision RAG generate answers and insights by combining retrieved text & images using LLMs like GPT ๐ค or Gemini ๐.
๐๏ธ Architecture Deep Dive
Explore the modular system design: from doc ingestion, through embedding generation, to answer production. ๐ ๏ธ
๐ ๏ธ Under the Hood
๐ณ Docker-first deployment
docker-compose up -d โ your database, extensions, and network are ready in seconds.
๐ PostgreSQLโฏ15 + pgvector
IVFFLAT indexing for blazingly fast cosine similarity ๐.
๐งฉ Unified ingestion layer
Extracts text (optionally via Tesseract OCR ๐๏ธโ๐จ๏ธ) and images from PDFs.
Page-as-image mode for layout-heavy docs.
Stores rich metadata for debugging and traceability ๐ต๏ธ.
๐ Query Layer
Converts questions into both text & vision vectors ๐ฏ.
