A new paper evaluates the feasibility of using GraphRAG with locally deployed open-source LLMs on consumer hardware for healthcare EHR schema retrieval. The study benchmarks models like Llama 3.1, Mistral, Qwen 2.5, and Phi-4-mini, revealing significant performance differences in knowledge graph construction, query latency, and answer quality. Results indicate that models around 7B parameters are necessary for reliable structured output, and local retrieval offers advantages in latency and factual grounding over global summarization. AI
