Overview
Experience less rate limiting and reduce the mental load of choosing a model by letting Copilot auto model selection automatically choose the best available model.
In VS Code and Visual Studio, Copilot auto model selection chooses from GPT-4.1, GPT-5 mini, GPT-5, Claude Haiku 4.5, and Claude Sonnet 4.5, based on availability and to help reduce rate limiting. Included models may change over time.
Automatically selected models won't include these models:
- Models with premium request multipliers greater than one. See Supported AI models in GitHub Copilot.
- Models excluded by individual or administrator policies. See Configuring access to AI models in GitHub Copilot.
- Models not available in your plan. See Supported AI models in GitHub Copilot.
To see which model was used for each response, hover over the response in Copilot Chat.
AI models for Copilot Chat
While auto model selection is an option for Copilot Chat, you can manually choose a different model to override this selection. You can change the model Copilot uses to generate responses to chat prompts. You may find that different models perform better, or provide more useful responses, depending on the type of questions you ask. Options include premium models with advanced capabilities. See Changing the AI model for GitHub Copilot Chat.
Multiplier discounts
If you are on a paid Copilot plan and use auto model selection, models qualify for a 10% multiplier discount. See Requests in GitHub Copilot.
