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.
