Arize AI

Say your support agent starts giving odd answers after a prompt change.

Arize AI is an AI observability and evaluation platform that lets you trace those calls, score the outputs, and see where the agent went wrong, whether the app is still in development or already live.

The platform covers generative AI, classic ML and computer vision, and it includes open source LLM tracing and evals for teams that want to start with something they can inspect.

The commercial product is called Arize AX.

It is built for building AI apps and agents and then tuning them once they are in production.

The core idea is a loop: production data feeds back into development, and the same trusted evaluations that you run while building also back your monitoring after launch.

That keeps testing and live checks measured against one standard instead of two separate ones.

Arize AI fits developers and ML teams who ship LLM applications and need to debug them with real traffic rather than guesses.

It is a developer tool, not a general office app, despite its category label.
