LEGO-GraphRAG: Modularizing Graph-based Retrieval-Augmented Generation for Design Space Exploration
Summary: Introduces LEGO-GraphRAG, a modular decomposition of graph+LLM RAG workflows to classify, compose, and synthesize GraphRAG instances. Uses the framework for large-scale design-space exploration, revealing tradeoffs among reasoning accuracy, latency, and token/GPU cost. (summarized by gpt-5-mini on Feb 09 2026)
