Arize AX
Arize AX traces, evaluates, and improves AI agents and applications using observability, issue detection, experiments, and managed agents.

In inglese
Arize AX is an AI engineering platform for capturing application traces, finding recurring failures, evaluating quality, and testing changes before deployment. It supports AI engineers and product teams working on agents and other AI applications.
The platform includes tracing, Signal issue detection, evaluators, datasets, experiments, prompt workflows, and Alyx. The free plan has usage limits; managed-agent workflows, repository access, self-hosting, and enterprise controls require higher-tier plans.
Features
- Capture traces for inputs, outputs, tools, sessions, and costs
- Use Signal to group recurring failures into ranked issues
- Search and filter traces with queries and AI Search
- Evaluate traces and spans with LLM, agent, and code evaluators
- Run experiments comparing prompts, models, or agent changes
- Build datasets and regression tests from production behavior
- Use Alyx for natural-language AI engineering assistance
- Access APIs, SDKs, CLI commands, and OpenTelemetry integrations
Use cases
- Trace production AI agents and inspect their tool calls
- Find recurring failures and investigate their likely causes
- Score agent responses against quality and safety criteria
- Compare prompt, model, retrieval, or agent changes
- Create regression datasets from failing production traces
- Monitor token usage, latency, and model costs

Latest updates
- Get Alyx help tailored to your experience
Alyx adapts how it helps based on your experience level in each part of Arize AX.
- Pick up where you left off with Alyx long-term memory
Alyx remembers durable context across conversations, including your preferences, ongoing goals, project and asset learnings, team conventions, and important decisions.
- Add and annotate entire sessions and traces in annotation queues
You can send full multi-turn sessions and complete traces to an annotation queue and review them at session or trace granularity.
- Inspect remote evaluator runs as traces
Remote evaluator runs now emit a trace for each evaluated row into your space’s evaluations project.
- Select OpenAI GPT-6 in the prompt playground
You can now select OpenAI’s gpt-6-astra in the prompt playground model picker and run prompts against it.
