It outlines how we generate the associations, validate the biological entities using biomedical ontologies, and verify associations using literature. The protocol includes a self-consistency strategy to assess generative reliability across ChatGPT models. To address ontology exact-match limitations, we provide a use case performing semantic verification through a workflow enabled by Retrieval-Augmented Generation (RAG) powered by open-source large language models (LLMs). This enables LLMs to establish truth over content generated by other LLMs and expose hallucination.engProtocol for evaluating ChatGPT in biomedical association generation and verification using a RAG enabled, cross-model majority voting workflowresearch article10.1016/j.xpro.2026.10453342133493001770377700001
