New RAG evaluator 'rag-triad' abstains from judgment when unsure

A new tool called rag-triad has been developed to evaluate the performance of retrieval-augmented generation (RAG) systems, addressing the limitations of current LLM-based evaluators. Unlike other tools that provide a single, confident score, rag-triad is designed to be more trustworthy by abstaining from judgment when it cannot reliably assess a response. It breaks down RAG failures into three categories: context relevance, groundedness, and answer relevance, with specific methods for each. A key feature is its 'fail-closed' groundedness check, which requires verifiable citations and abstains rather than fabricating a score when a citation is missing or incorrect. The tool also includes a self-testing mechanism to validate its own reliability. AI

IMPACT Provides a more reliable method for evaluating RAG systems, potentially improving the trustworthiness of AI-generated answers.
