Arize AI provides Arize AX, a managed platform for AI observability and evaluation, and Phoenix, a related product for tracing, evaluating and improving AI agents and LLM applications. Phoenix is built on OpenTelemetry, captures prompts, retrievals and tool calls, and can run locally or in your own environment with Docker or Kubernetes. The vendor describes it as open source and publishes it under the Elastic License 2.0. A self-hosted version of Arize AX is also available. Arize AI is aimed at teams that build AI applications and monitor them in production.
Arize AI is a US vendor. For the managed platform it relies on cloud infrastructure from GCP, AWS and Azure, and it offers EU data residency so that data stays within the European Union; no specific region or data centre is named. According to the vendor, organisations that self-host Phoenix keep their traces in their own environment. For a European organisation, self-hosting or the EU option is therefore the route to keeping data under its own control, while the vendor itself remains subject to US jurisdiction.
