I Built GraphRAG From Scratch — Then a December 2025 Paper Made It Look Basic
A developer detailed their experience building a GraphRAG system, a method for enhancing retrieval-augmented generation (RAG) with graph data structures. They found their custom implementation was significantly surpassed by a recently published paper detailing a new architecture called HGMem. This new approach appears to address limitations in binary graph representations that their own system struggled with. AI
IMPACT Introduces a novel architecture that significantly advances RAG capabilities, potentially setting a new standard for information retrieval in AI systems.
