AI Evaluation and Observability Platforms

AI Evaluation and Observability Platforms Reviews and Ratings

What are AI Evaluation and Observability Platforms?

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.

Features of AI Evaluation and Observability Platforms

Updated February 2026

Mandatory Features:

  • AI system observability: Capture logs, metrics, and traces at various levels of granularity, ranging from multistep agentic workflows to a single request-response interaction with an AI model. Logs and traces provide insights into reliability measures such as latency and error rates; trust measures such as explainability, correctness, relevance, and fairness; and cost measures such as token costs.

  • Automation of evaluation runs: The ability to systematically test an AI system against a predefined dataset and score the outputs with custom rubrics, using multiple evaluators — code-based functions, human judgment, or LLM-as-a-judge. The ability to use evals as quality gates and ensure safety and alignment by preventing regressions and unexpected outputs from reaching production.

  • Online and offline evaluations: Support for both online and offline evaluation capabilities. Offline evaluation includes support for testing the application’s performance on curated or external datasets in preproduction environments. Online evaluation includes “live” monitoring of application behavior in production to assess performance and take suitable actions in real time.

  • Prompt life cycle management: Support the ability to create, parameterize, version, test and replay prompts. Prompt parametrization and versioning promote reusability.

  • Sandbox environments for interactive experiments: The sandbox environments enable technical and nontechnical stakeholders to iterate on prompts rapidly, experiment with different models and their parameters (e.g., temperature), and visually compare outputs in real time. The environments connect to model provider APIs via API keys and do not need to host the models.

  • Dataset management and curation: Curate and manage evaluation datasets at scale. Datasets are a collection of sample prompts with additional context and optional expected outputs. This feature includes capabilities to create new datasets from scratch, upload existing data, manage different versions, and annotate or label data points with ground-truth answers or desired outputs.

  • Support for creating custom metrics to suit application-specific needs: Support the use of general-purpose metrics frameworks such as Ragas, G-Eval and GPT Estimation Metric-Based Assessment (GEMBA) to quantify subjective measures of faithfulness, coherence, relevance, and precision. Support the creation of application-specific metrics tailored to meet safety and alignment goals.

  • Model-agnostic nature: To prevent vendor lock-in and support versatile use cases, AEOPs must be model-agnostic, supporting multiple commercial and open-source models across frontier model providers.
