Graph RAG vs Vector RAG: When to Use Each
This article compares two primary approaches to Retrieval-Augmented Generation (RAG) for large language models: Vector RAG and Graph RAG. Vector RAG uses similarity-based retrieval of text chunks stored in a vector database, offering simplicity and speed. Graph RAG, conversely, models knowledge as nodes and relationships, enabling retrieval based on structural context and multi-hop reasoning. The choice between them depends on the complexity of queries and the importance of relationships versus semantic similarity. AI
