Learn how to combine Neo4j knowledge graphs with LangChain to build accurate, explainable, and production-ready Retrieval-Augmented Generation (RAG) systems.

Retrieval-Augmented Generation (RAG) has quickly become the go-to architecture for making Large Language Models (LLMs) useful in production. Instead of relying solely on the LLM’s internal memory, RAG connects it with external knowledge sources.

This article discusses the integration of Neo4j with LangChain to create efficient and explainable Retrieval-Augmented Generation (RAG) systems. It covers the motivation for using knowledge graphs, the setup process, and concrete steps for connecting to Neo4j, ingesting data, and implementing hybrid retrieval mechanisms. The pieces highlight the workings of LangChain with Cypher queries, as well as the benefits of leveraging both vector databases and graph-based models to create production-ready AI systems that provide reliable and interpretable outcomes.
