Microsoft GraphRAG
GraphRAG is Microsoft’s open source implementation of graph-based retrieval-augmented generation for large language models. Rather than relying solely on vector similarity search, GraphRAG uses knowledge graphs to provide structured, context-rich retrieval that significantly improves LLM responses on complex, multi-hop reasoning tasks. It is one of the most widely adopted open source GraphRAG implementations available.
