Microsoft has introduced a preview of “Auto Model Selection” for GitHub Copilot that automatically chooses the optimal AI model for each task — removing the need for manual model selection. The feature promises faster responses, fewer rate-limit issues and even a 10 % discount on premium requests for paid users.

Here’s what you need to know:

Why Use Auto Model Selection
Skip the guesswork — Copilot automatically chooses the best AI model for your task, helping you focus on building instead of configuring.
How It Works
Copilot intelligently picks the optimal model to deliver top performance and reduce rate limits. It can switch between GPT-5, GPT-5 Mini, GPT-4.1, Claude Sonnet 4.5, Claude Haiku 4.5, and others — unless your organization enforces a single model. Currently, paid users benefit from the Claude Sonnet 4.5 model by default.
What’s Next
GitHub plans to expand Auto Model Selection with dynamic switching between models, broader language model support, and improved transparency for users.
