Arize Phoenix + LangChain

by Arize AI · freemium · Last verified 2026-03-17

Arize Phoenix integrates with LangChain to provide deep observability for LLM applications. By leveraging OpenTelemetry, it captures and streams traces for chains, agents, and retrievers to a local UI or the Arize cloud. This enables developers to debug applications, detect embedding drift, score retrieval quality, and analyze hallucinations at the span level.
