Arize AI

arize.com

Arize AI develops observability and evaluation infrastructure for AI applications, including large language models, agents, multimodal systems and traditional machine learning. Its managed Arize AX platform and open-source Phoenix library let engineering teams trace application behavior, run evaluations, inspect failures, compare experiments and monitor production performance. These tools help teams diagnose model drift, hallucinations and unreliable agent behavior, then improve prompts, models and workflows using evidence from development and production. Phoenix integrates with OpenTelemetry and OpenInference instrumentation. Dynatrace completed its acquisition of Arize on October 1, 2026; Arize continues to provide its AI engineering products within Dynatrace.
