Key features:
- Holistic Scoring: Evaluates entire conversations rather than individual steps.
- Cost Efficiency: In benchmarks, the tuned model achieved higher accuracy at 82% lower cost than frontier models.
- Dev Workflow: Directly integrates feedback into agent improvement cycles, easing the burden on developers.
