A comprehensive guide to AI observability and evaluation platforms, covering key features like prompt management, observability, and evaluations. It includes a comparison of platforms like LangSmith, Langfuse, Arize, OpenAI Evals, Google Stax, and PromptLayer, and a step-by-step guide on how to run the evaluation loop.
Three Core Capabilities: The best AI observability/eval platforms focus on Prompt Management (versioning, parameterization, A/B testing), Observability (logging requests and traces, capturing data via APIs, SDKs, OpenTelemetry, or proxies), and Evaluations (code-based, LLM-as-judge, and human evaluations; online evals, labeling queues, error analysis).

OpenInference is a set of conventions and plugins that complements OpenTelemetry to enable tracing of AI applications, with native support from arize-phoenix and compatibility with other OpenTelemetry-compatible backends.
