Evaluating Large Language Model (LLM) providers requires a more rigorous approach than simply comparing demo outputs. Key metrics for production readiness include accuracy consistency over time, latency at the 95th percentile (p95) to reflect user experience, and the actual cost per evaluation run, which can become substantial. Additionally, tracking regression frequency is crucial, as providers may silently update models, altering behavior without notice. AI
