Evals became our safety net for deploying AI at scale - we couldn't afford to ship agent regressions that impact thousands of customers.

The tracing in Judgment shows us exactly what our agents are doing in production - really valuable.

We exported our thousands of agent traces from Judgment and used them for agent RL training - our task completion rate jumped 20%.
