Graph RAG vs Vector RAG: When to Use Each
Retrieval-Augmented Generation (RAG) helps LLMs use external knowledge more reliably. In practice, two patterns show up often: Vector RAG and Graph RAG.
Both try to solve the same problem: bring relevant context to the model. They just do it with different data models.
Vector RAG: similarity-based retrieval
Graph RAG: relationship-based retrieval
