UnverifiedIn independent RAG evaluation, faithfulness and relevance metrics usually require human annotation or LLM-as-judge scoring, which makes evaluation costly and is one of the important sources of price differences.72% similarUnverifiedRAG evaluation requires separately considering recall (whether retrieval finds the correct content) and faithfulness (whether the generated answer is truly based on the retrieved material).69% similarUnverifiedAnswer accuracy and retrieval faithfulness are two mutually independent evaluation dimensions; faithfulness evaluation requires verifying whether each key claim in the answer can be directly traced back to the retrieved documents.63% similarUnverifiedVanity metrics are data that look good but do not directly reflect business health, such as cumulative registered users, page views, or total early contract value; actionable metrics such as customer acquisition cost (CAC), customer lifetime value (LTV), sales cycle length, and net revenue retention (NRR) can directly guide adjustments to sales strategy.63% similar
