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 on your behalf.

With Copilot auto model selection, you benefit from:

Auto model selection won't include these models:
- Models excluded by individual or administrator policies. See Configuring access to AI models in GitHub Copilot.
- Models with premium request multipliers greater than one. See Supported AI models in GitHub Copilot.
- Models not available in your plan. See Supported AI models in GitHub Copilot.
