From Prompts to RAG to RAGAs: Evaluating Retrieval-Augmented Generation Systems the Right Way

Most RAG demos look impressive. But ask them the wrong question and they hallucinate, miss relevant docs, or contradict their own sources. RAGAs give AI engineers a way to measure and fix these failures before they hit production.

This article discusses the evolution from prompt engineering to Retrieval-Augmented Generation (RAG) and its evaluation through RAGAs. It highlights the limitations of traditional methods, such as hallucinations in GPT models, and underscores the importance of evaluating RAG systems on metrics like retrieval quality and answer correctness. The post also outlines best practices for building effective RAG evaluation sets and introduces a code tutorial for implementing and assessing these systems to enhance reliability in production environments.
