Regression testing for model upgrades
Model providers retire versions on their own schedule. A prompt tuned for one model can behave differently on the next. We run your suite on both and show you what changed before your users notice.
What we test
- Side-by-side runs on the current and the new model
- Changes in refusals, tone, accuracy and tool use
- Prompt adjustments needed for the new version
- Cost and latency differences on your workload
What you get
A change report with the cases that got better, worse or different, and a go or no-go recommendation with reasons.
Where the fix is in the setup (a prompt, a permission, a retrieval or guardrail setting) we make it and run the failed cases again. The test suite is yours to keep.
Who asks for this
Teams facing a model deprecation date or considering a cheaper model.
