Agent Evaluation Metric for multi-turn conversations
One early mistake corrupts every later turn. AWS open-sources a turn-level evaluation metric that pinpoints where multi-turn agents actually break.
Why it matters
Agent reliability engineering is moving from 'did the agent succeed?' to 'where did it fail and why?' This is the measurement infrastructure practitioners need to debug and improve production agents.

Publisher excerpt: Multi-turn agents fail in ways single-turn evaluation misses: one early mistake corrupts every later turn. This post introduces the Agent Evaluation Metric (AEM), a decomposable, turn-level way to measure agent quality, applied to its first dimension, correctness, to pinpoint the turn that caused a…
