Field notes from voice AI in production.

Working notes on the gap between a voice AI demo and a deployment that survives Monday morning. Evaluation, gating, drift, and the failure modes that only appear on real traffic.

Voice agents are not pipelines. They are competing loops.

A voice agent is not one loop. It is several, competing over the same call. A benchmark of one of them, the interruption loop, shows why the observation boundary, not the model, is the architecture.

Shadow mode is not a formality

The first gated stage exists to surface the failures that only appear on real traffic, before a single customer is affected.

Continuous Proof

Drift is the rule, not the exception

A voice agent that passed acceptance in January is a different system in June. Scheduled eval runs are how you find out before your customers do.
