A hands-on workshop from Arize AI on moving from vibe checks to real LLM evals. It covers what an eval is and how it differs from a unit test, the main eval types, how to read agent traces, how to write concrete pass/fail criteria, and how to build and iterate on an LLM-as-a-judge in Arize's prompt playground.
Fuad Ali from Arize AI explains why voice agents are uniquely challenging to debug, as critical issues like latency, interruptions, and tone are invisible in text logs. He presents a solution combining unified audio, transcript, and trace views with OpenInference semantic conventions and audio-native evaluations. The talk culminates in a vision for self-healing voice agents through automated observation, evaluation, and improvement cycles, demonstrating how to achieve robust, continuously improving AI voice systems.
