Building a Biomedical GraphRAG Inference System: Comparing LLM-Only, Basic RAG, and GraphRAG Pipelines
The article discusses the development of a biomedical GraphRAG inference system that compares LLM-only, Basic RAG, and GraphRAG pipelines. The aim is to address challenges in production AI systems, such as hallucinations and retrieval inefficiencies, particularly in the biomedical domain. The GraphRAG system leverages structured knowledge graphs to enhance explainability and relationship-aware reasoning.
- ▪The GraphRAG inference system was built to compare different inference methods in terms of latency, token usage, cost, grounded accuracy, and reasoning quality.
- ▪Traditional RAG methods struggle with multi-hop reasoning and relationship-aware retrieval, which are crucial in biomedicine.
- ▪The system utilizes FAISS for semantic vector retrieval and TigerGraph for structured biomedical relationships.

Traditional vector-based Retrieval-Augmented Generation (RAG) improves grounding, but it still struggles with multi-hop reasoning and relationship-aware retrieval.
