Gartner defines AI evaluation and observability platforms (AEOPs) as tools that help manage the challenges of nondeterminism and unpredictability in AI systems. AEOPs automate evaluations (“evals”) to benchmark AI outputs against quality expectations such as performance, fairness and accuracy. These tools create a positive feedback loop by feeding observability data (logs, metrics, traces) back to evals, which helps improve system reliability and alignment. AEOPs can be procured as a stand-alone solution or as part of broader AI application development platforms.
