Build a Retrieval Augmented Generation (RAG) application in Python to query and chat with PDF documents using generative AI. Explore advanced topics including local RAG implementation with Ollama, vector database updates, PDF integration, and AI response quality testing. Follow along with code examples and learn how to load PDF data, generate embeddings, store and update information, run RAG locally, and implement unit tests for AI output. Access the GitHub repository for the complete project and dive into additional resources on document loaders, PDF handling, and Ollama integration.
