How AI describes Arize Phoenix

Phoenix is an open-source platform for developing and evaluating AI agents, providing tracing, annotation, hypothesis generation, experimentation, and measurement to improve agent quality. It lets you trace every step of an agent’s prompts, retrievals, tool calls, and outputs; annotate what works or breaks; create datasets from traces; run experiments; and score results across cost, latency, and performance. The platform supports self-hosting or cloud deployment, OpenTelemetry integration, and is designed to work with any model, framework, or language for a vendor-agnostic AI engineering workflow.
