advancedSpring AI — Core, ChatClient & RAG

How do you evaluate a RAG pipeline? What metrics matter?

Retrieval metrics: Precision@k, Recall@k, MRR. Generation metrics: ROUGE, BLEU, METEOR against reference answers. RAG-specific: Faithfulness (is the answer grounded in the retrieved context?), Answer Relevance, Context Precision — tools like RAGAS, Arize, and LangSmith automate this.
