Build an Agentic RAG Pipeline with LangGraph + ChromaDB (Step-by-Step Tutorial)
Unlock the power of agents by building a fully functional Agentic RAG (Retrieval-Augmented Generation) pipeline using LangGraph and ChromaDB. In this step-by-step tutorial, we’ll explore how to structure intelligent agents, retrieve from Vector DB (chromaDB), build prompts, and connect everything into a production-ready RAG system. Perfect for developers, AI enthusiasts, and anyone building LLM-powered applications. ⭐ What You’ll Learn: - What Agentic RAG is and why it’s the next evolution of retrieval systems - Setting up LangGraph for agent orchestration - Using ChromaDB for efficient vector storage and retrieval - Building custom tools, nodes, and agent loops - Implementing context retrieval, routing, and reasoning steps - Running the entire pipeline end-to-end - Tips for optimizing retrieval quality and agent behavior 💡 Who This Is For: Developers, ML engineers, researchers, and anyone aiming to build advanced LLM applications with modular, agentic intelligence. 📁 Resources: Notebook on Github (please star the repo): https://github.com/ai-bites/generative-ai-course/blob/main/agentic_rag_chromadb.ipynb Kaggle Medical Devices Dataset: https://www.kaggle.com/datasets/pratyushpuri/global-medical-device-manuals-dataset-2025?resource=download Medical Q&A Dataset: https://www.kaggle.com/datasets/thedevastator/comprehensive-medical-q-a-dataset 👍 If you enjoy this video: Like, comment, and subscribe for more tutorials on LangChain, LangGraph, vector databases, and AI engineering! ⌚️ ⌚️ ⌚️ TIMESTAMPS ⌚️ ⌚️ ⌚️ 0:00 - Intro 1:10 - Drawbacks of Naive RAG 2:11 - Agentic RAG overview 3:10 - Datasets used 4:26 - Tools and Frameworks used 4:59 - Agentic RAG pipeline 5:40 - Hands-on Coding 15:05 - Building LangGraph StateGraph 26:46 - Conclusion and Extro AI BITES KEY LINKS Website: https://www.ai-bites.net YouTube: https://www.youtube.com/@AIBites Twitter: https://twitter.com/ai_bites Patreon: https://www.patreon.com/ai_bites Github: https://github.com/ai-bites
