Compare is Chat A and Chat B on the same collection. It is not a comparison of two catalogs.
Set the two sides
Choose Compare mode. Chat A and Chat B each have a question and a policy. Copy Chat A settings to Chat B when you want the same start. Then change one setting, or change the question on purpose. If you leave Chat B’s question empty, it reuses Chat A’s question.
Run
Run, stop, or retry each side on its own. One side can finish while the other fails. A prior-result mark means that side is showing an earlier run, not a new one.
How to read the difference
Highlighted words are text that differs. They are not a difference in evidence, and they are not an Eval Studio score. Evidence differences are which passages each side cited. If a side has no citation, that side did not ground its answer. Do not treat the prettier paragraph as the better one.
