Build a RAG System from Scratch with Python

Description: GitHub repo link - https://github.com/sjsoumil/RAG-vs-GraphRAG In this hands-on video, you will build a complete classic RAG system from scratch using Python, LangChain, OpenAI, and ChromaDB. This is a fully running, end-to-end implementation with live output shown on screen. What you will build: A document ingestion pipeline with loaders and chunking An embedding pipeline using OpenAI embeddings A vector store with ChromaDB for similarity search A retrieval and generation pipeline with LangChain Live query runs with actual outputs shown This is a prerequisite before you comp…
