description: Arize AI is an AI engineering and observability platform for LLM applications, agents, and traditional ML
  systems. The commercial Arize AX platform (with Generative and ML & CV variants) provides tracing, evaluation, experiments,
  prompt management, and the Alyx AI engineering agent, built on the OpenInference OpenTelemetry conventions. Phoenix is
  the open-source counterpart used by tens of thousands of developers for local tracing, evaluation, and prompt iteration.
  Arize is vendor- and framework-agnostic with 30+ instrumentation providers and an OTLP-native ingestion path.
