Mastering Retrieval-Augmented AI with LangChain & LangGraph: Building High-Performance Vector Stores, Knowledge Pipelines, and Specialized Agents

By Yuan Li

Mastering Retrieval-Augmented AI with LangChain & LangGraph
Build production-ready RAG pipelines, integrate vector databases, and unlock next-generation AI search capabilities
Retrieval-augmented generation (RAG) has become the backbone of serious AI applications from enterprise chatbots to knowledge assistants. Yet most resources stop at toy examples. This book takes you beyond the basics, showing how to combine LangChain and LangGraph to design, implement, and scale real-world retrieval pipelines that actually work in production.
Inside you'll learn how to:
Design and deploy RAG pipelines with LangChain - go from query to context to answer using proven patterns.
Integrate and optimize vector databases - Pinecone, Weaviate, Milvus and more for high-speed semantic retrieval.
Use LangGraph to orchestrate dynamic workflows - conditional logic, multi-step retrieval, and runtime adaptations.
Handle enterprise constraints - sharding, caching, batching, and latency reduction for large-scale deployments.
Apply RAG across domains - knowledge assistants, customer support bots, code search, and research tools.
Every chapter pairs architectural explanations with working code walkthroughs so you can see exactly how each concept is implemented. By the end of the book, you'll have the skills and reusable templates to build resilient, scalable retrieval-augmented systems for your own projects or your organization.
Whether you're an AI engineer, data scientist, developer, or technical lead, this guide will help you move beyond prototypes and start delivering high-value, production-grade RAG applications.
Take control of retrieval-augmented generation today and build AI systems that answer with speed, accuracy, and scale.
