### [GEO tools with same-conditions retest](https://winin.ai/en/answers/geo-tools-same-conditions-retest/)

Write same-conditions retest into the RFP: can the vendor freeze prompts/models/language/windows, retain raw answers, and explain what changed vs what

### [How to run a same-conditions retest (method)](https://winin.ai/en/answers/same-conditions-retest-method/)

To run a same-conditions retest: freeze the ruler, take a baseline, ship only approved changes, measure again under the same conditions, then report w

### [Same-conditions retest playbook](https://winin.ai/en/digest/same-conditions-retest-playbook/)

Method note—not a performance promise. Retest proves change under comparable observation, not permanent model recommendation.
