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. It felt so nice compared to everything else we tried.

Being able to iterate quickly on agents with real feedback loops has been a game changer.

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

Honestly didn't think we needed evals until we tried it. Catches stuff we never would have seen.

The monitoring in Judgment has been super useful for tracking our agent tool usage across different scenarios.
