About Arize AI

Arize AI is an AI engineering platform that provides unified observability, evaluation, and tracing for LLMs, AI applications, and agents. It combines hosted cloud services and open-source components (notably Phoenix and OpenInference) to capture predictions, labels, traces, and evaluation runs, enabling teams to detect data quality issues, concept and performance drift, and agent behavior problems. Arize integrates SDKs across languages, uses OpenTelemetry-based tracing to correlate model inferences with application spans, and offers deployment options for cloud or self-hosted (Docker/Kubernetes Phoenix containers). The platform is designed to support large-scale logging and evaluation workloads and to accelerate debugging, governance, and reliability of production AI systems.
