Short answerWhenever the model, instructions, files or settings change, rerun the same test set and compare to the last passing results. Keep a log so you can see what changed.
When to retest
- You switch models or the provider changes a default.
- You edit instructions or settings.
- You add or replace files.
- Costs or complaints change unexpectedly.
How
- Keep your test set and the last accepted answers in a sheet.
- Run the set and record new answers.
- Mark differences as better, same or worse.
- Investigate "worse" first; revert the change if needed.
- Update the log: date, what changed, result.
