GitHub Copilot Auto Becomes Default for Free and Student Users

GitHub is making another major change to Copilot as it continues to manage growing demand for its AI coding assistant. After previously introducing usage limits and token-based pricing for some plans, the company is now removing manual AI model selection for Copilot Free and Copilot Student users.

Going forward, users on those plans will no longer be able to manually choose between AI models from OpenAI, Anthropic, Google, or Microsoft. Instead, GitHub’s Copilot Auto mode will become the only available model selection option, automatically choosing which AI model handles each request. The change is part of GitHub’s broader effort to improve reliability while reducing latency and failed requests.

Copilot Auto will decide which AI model to use

According to GitHub, Copilot Auto evaluates each prompt before deciding which AI model is best suited for the task. Rather than relying on a single model, the system can select from multiple model families depending on request complexity, service health, and current availability.

For example, straightforward coding questions may be routed to faster, lower-cost models, while more demanding programming or reasoning tasks can use more capable AI models. GitHub says this dynamic routing should help deliver faster responses while lowering the chances of users encountering rate limits or unavailable models.

GitHub has not published a permanent list of models that Copilot Auto will use. Instead, the company says available models may change over time as new models become available or existing ones are updated.

Sessions will keep using the same model

Although Copilot Auto chooses the model automatically, GitHub says it generally avoids switching models during an active chat session.

The company found that changing models in the middle of a conversation increased compute costs without providing a meaningful improvement in response quality. Users will still be able to see which model generated each response, even though they can no longer choose it manually.

GitHub is also removing the “Preview” label from Microsoft-developed AI models. The company says the label is no longer necessary because Copilot Auto continuously manages model routing and background updates without requiring users to distinguish between preview and production models.

In other GitHub news, the company recently launched the GitHub Copilot desktop app, bringing its AI coding assistant to a dedicated desktop experience outside the browser.
