Arize AX: The Agent Experience

Agent debugging needs end to end workflows

Will this fix actually make things better?

Observe

What did my agent actually do?

Trace everything from the team who founded OpenInference - the leading open standard for GenAI observability.

Evaluate

Is my agent getting better or worse?

The most comprehensive eval framework in the market. Run span, trace, and session evals that run at scale.

Built for AI Engineers

Infrastructure for self‑improving agents.

Teams can build agents faster than they can review traces. Signal surfaces what matters, uncovers root causes, and generates review-ready fixes.

Alyx: Your AI engineering agent

Like Cursor or Claude Code, but for AI engineering. Alyx runs evals, debugs issues, and improves your agents. Give it a problem. It fixes it.

FAQ

Everything you need to know about Arize AX and Phoenix.

Connect your agent or application to Arize and send your first trace. Traces show what happened inside each request, giving you the data you need to debug, evaluate, and improve your agents.

Start setting up traces for your agent.

Once you get going, you can always ask Alyx, our in-app AI engineering agent for help.

Phoenix is the leading open-source platform for AI observability and evaluation. Developers use Phoenix to trace AI applications, run evaluations, investigate failures, and improve quality. Built on OpenInference and OpenTelemetry standards, Phoenix integrates with tools including OpenAI, Anthropic, LangGraph, LangChain, CrewAI, and LlamaIndex. Run locally or self-host.

Arize AX is the managed AI engineering platform built on the same open standards. It adds managed infrastructure backed by the industry’s fastest and most scaled observability datastore: adb, advanced agent observability, online evals, and continual improvement workflows that help teams monitor, improve, and scale production AI systems.

Don’t ship vibes.

Arize gives AI teams observability and evals to understand and improve agent performance.
