Accepted at <strong>EMNLP 2025</strong>, it replaces the traditional flat vector store approach with a graph-based architecture that extracts entities and their relationships from documents, enabling dramatically better context understanding for LLM applications.</p> <p>Where conventional RAG systems retrieve isolated document chunks by embedding similarity, LightRAG builds a structured knowledge graph from your documents &ndash; entities become nodes, relationships become edges. When a query arrives, it performs <strong>dual-level retrieval</strong> across this graph: low-level retrieval for specific factual answers, high-level retrieval for broader thematic summaries. The result is retrieval that understands not just what words appear together, but how concepts are actually connected.</p>
