 ## Performance Analysis
 
-We conducted a comprehensive analysis of the performance of three Large Language Models (LLMs) - Llama-2-13b, GPT-3.5-Turbo (0613), and GPT-4 - on the BiomixQA dataset. We compared their performance using both a standard prompt-based approach and our novel Knowledge Graph Retrieval-Augmented Generation (KG-RAG) framework.
