 ### Premium requests
 
-{% data variables.product.prodname_copilot_short %} code review uses multiple models behind the scenes. The initial request is made using the o3-mini model. As {% data variables.product.prodname_copilot_short %} generates suggestions throughout the pull request, it may use GPT-4o or other models, depending on the code and type of review.
-
-Because different models have different multipliers, the number of premium requests used during a code review will vary based on the size of the pull request and the amount of code {% data variables.product.prodname_copilot_short %} needs to analyze and respond to. See [AUTOTITLE](/copilot/managing-copilot/managing-copilot-as-an-individual-subscriber/monitoring-usage-and-entitlements/avoiding-unexpected-copilot-costs).
+Each {% data variables.product.prodname_copilot_short %} code review consumes one premium request. See [AUTOTITLE](/copilot/managing-copilot/monitoring-usage-and-entitlements/about-premium-requests).
 
 ### Maximum code reviews per month
 
 The **review changes** type of {% data variables.copilot.copilot_code-review_short %} is a premium feature with a per-person monthly quota.
 
 <!-- expires 2025-05-05 -->
 > [!NOTE]
-> The per-person quota for Copilot code review will commence on May 5th, 2025.

 <!-- end expires 2025-05-05 -->
 
 When you assign {% data variables.product.prodname_copilot_short %} as a reviewer for a pull request, one premium request is deducted from your monthly quota each time {% data variables.product.prodname_copilot_short %} posts comments to the pull request.
 
 If a repository is configured to automatically request a code review from {% data variables.product.prodname_copilot_short %} for all new pull requests, the premium request usage is applied to the quota of the pull request author. If a pull request is created by {% data variables.product.prodname_actions %} or by a bot, the usage will apply to the user who triggered the workflow (if identifiable), or to a designated billing owner.
 
-When you reach your monthly quota you will not be  able to get a code review from {% data variables.product.prodname_copilot_short %} until your quota resets—unless you upgrade your {% data variables.product.prodname_copilot_short %} plan or enable additional {% data variables.product.prodname_copilot_short %} premium requests. See [AUTOTITLE](/copilot/managing-copilot/managing-copilot-as-an-individual-subscriber/monitoring-usage-and-entitlements/avoiding-unexpected-copilot-costs).
