Model evaluation asks whether a system performs well enough for its intended use, on data representative of deployment, with known uncertainty and failure modes. Responsible evaluation is required for recommendation, automated decisions, predictive services, generative AI, safety-relevant systems, fraud detection, healthcare support, education technology, and any deployment affecting people or operations.
