A hackathon project demonstrated that GraphRAG, a method utilizing knowledge graphs for information retrieval, can significantly reduce token usage in LLM queries. By traversing connected facts within a graph instead of relying on similarity search for document chunks, GraphRAG achieved a 56.4% token reduction compared to basic RAG while maintaining answer accuracy. This approach is particularly effective for complex, multi-hop questions, offering a more structured and efficient way to provide context to LLMs. AI
