Short summary
A detailed guide to building production-grade LLM evaluation pipelines, motivated by a real incident where a RAG assistant hallucinated responses to 500+ users. It covers judge ensembles (faithfulness, instruction following, JSON schema, safety, domain expert), golden dataset management, and CI/CD integration with code examples. The pipeline reportedly catches 92% of hallucinations pre-deployment.
