+# Copilot usage and models in Visual Studio
+
+GitHub Copilot now follows a [new billing model](https://docs.github.com/en/copilot/managing-copilot/monitoring-usage-and-entitlements/about-premium-requests). With this update that impacts usage and billing for [premium requests](https://docs.github.com/en/copilot/managing-copilot/monitoring-usage-and-entitlements/about-premium-requests#premium-requests), Visual Studio has introduced new features to help you better manage your Copilot usage and the models you work with.
+
+## What's changed?
+
+If you’re a **paid Copilot user**, your plan now includes a **[monthly allowance of premium requests](https://docs.github.com/en/copilot/about-github-copilot/plans-for-github-copilot#comparing-copilot-plans)**. These requests are used whenever you interact with Copilot using premium models, like Claude Sonnet 3.7. Once you reach your quota, Copilot in Visual Studio automatically switches to a base model, ensuring uninterrupted workflow.
+
+For users on **Copilot Free**, your account comes with up to 2,000 code completions and up to 50 chats or premium requests per month.
+
+## What’s new in Visual Studio?
+
+New tools and smarter defaults make it easier to track usage and get the most out of Copilot.
+
+### Smarter default models
+
+Visual Studio now defaults to **GPT-4.1**, a fast and balanced model. If you exhaust your premium quota, it automatically switches to the **fallback model**, ensuring uninterrupted access to powerful features at no extra cost.
+
+> 💡 Once you select a model, it stays active for your current chat session—no need to reselect it between threads.
+
+### Smarter usage insights
+
+To track your Copilot usage:
+
+1. Select the **Copilot badge** in the top-right corner of Visual Studio.
+2. Select **Copilot Consumptions**.

+
+Here, you can view your usage across chat, auto (agent) mode, and other features. You can also select **Get more requests** to update your subscription or adjust Overage settings directly on *GitHub.com*.
+
+### Smarter fallback behavior
+
+- **Overages ON**: You can keep using premium models beyond your monthly quota, with any extra usage billed to your account.
+- **Overages OFF**: Copilot automatically switches to the fallback model once you reach your quota, preventing unexpected charges.
+
+To control model usage in non-chat interactions, configure the setting **Enhance non-chat requests with premium models** in **GitHub** > **Copilot** > **Editor**.
+
+### Easier model management
+
+Use the updated **model picker** experience.
+
+> If a model is supported by your plan but not yet enabled, Visual Studio prompts you to activate it—no need to leave the IDE.
+

+
+## Frequently asked questions
+
+#### Do Completions count as premium requests?
+
+**Code completions** do *not* count against your premium request balance for paid users.
+
+#### What are premium requests?
+
+Some Copilot features use more advanced processing power and count as premium requests. See [premium requests and premium features](https://docs.github.com/en/copilot/managing-copilot/monitoring-usage-and-entitlements/about-premium-requests#premium-requests) to learn more.
+
+#### Who can purchase additional premium requests?
+
+To learn more, see [Additional premium requests](https://docs.github.com/en/copilot/managing-copilot/monitoring-usage-and-entitlements/about-premium-requests#additional-premium-requests).
+
+#### How is premium request usage assessed?
+
+Premium request usage is based on the [model’s multiplier](https://docs.github.com/en/copilot/managing-copilot/monitoring-usage-and-entitlements/about-premium-requests#model-multipliers) and the feature you’re using. To learn more, see [Example of premium request usage](https://docs.github.com/en/copilot/managing-copilot/monitoring-usage-and-entitlements/about-premium-requests#example-of-premium-request-usage.)
