CI/CD gates built for AI.
Block merges on regression
Set score thresholds per experiment. When a PR drops below them, checks fail and the merge blocks. No manual review required.
Track LLM cost per experiment
Every eval logs token usage and cost automatically. Compare cost across model versions and prompt changes before anything reaches production.
Diff any two experiments
Pick any two runs and see exactly which inputs got better or worse, side by side. Know what changed before you ship it.
