What is GitHub Copilot Student
GitHub Copilot Student is a version of GitHub Copilot tailored for students, providing AI-powered code suggestions. It helps students write code faster and learn programming concepts [4]. This plan offers access to various AI models for code generation and completion [5].
What is new vs the previous version
The new change involves the removal of GPT-5.3-Codex from the model picker for Copilot Student users. Previously, students could directly select GPT-5.3-Codex from a list of available models [1]. Now, manual selection is not possible, but the model is still accessible via auto model selection [1].
| Feature | Previous Version (before ) | Current Version (after ) |
|---|---|---|
| GPT-5.3-Codex in Model Picker | Available for direct selection [2] | Not available for direct selection [1, 5] |
| GPT-5.3-Codex via Auto Selection | Available [1] | Remains available [1, 5] |
| Other Premium Models | Some were directly accessible [6] | Some removed from direct access [6] |
| Target Audience | GitHub Copilot Student plan users [1] | GitHub Copilot Student plan users [1] |
How does auto model selection work
Auto model selection is designed to automatically choose the most appropriate AI model for a given coding task [1]. This system aims to match the specific requirements of the user’s input with the capabilities of available models [1]. It ensures that even if a model is not in the picker, it can still be utilized when deemed suitable by the system [1].

Who should care
Builders
Builders, especially student developers, should care as this change affects their direct access to specific AI models. They will rely more on Copilot’s auto model selection for GPT-5.3-Codex [1].
Enterprise
Enterprise users are not directly affected by this specific change to the Student plan. However, they should note GitHub’s approach to model management and availability across different tiers [3].
End users
End users of the Copilot Student plan are directly impacted by the inability to manually select GPT-5.3-Codex. Their experience will now be guided by the auto model selection [1].
Investors
Investors in AI development tools and platforms should observe how GitHub manages its model offerings. This indicates strategic decisions regarding model access and plan differentiation [3].
How to use GitHub Copilot today
To use GitHub Copilot, users typically install the Copilot extension in their IDE, such as Visual Studio Code. Once installed and authenticated, Copilot provides code suggestions directly within the editor. For Copilot Student users, GPT-5.3-Codex will be automatically invoked by the system when appropriate, without manual selection [1]. Copilot Enterprise and Business plan administrators must enable GPT-5.5 policy in Copilot settings [3].

Risks, limits, and myths
- Myth: GPT-5.3-Codex is entirely removed from the Copilot Student plan. This is false; it’s only removed from the model picker, remaining available via auto selection [1].
- Limit: Manual control over GPT-5.3-Codex selection is lost for students. Students can no longer force the use of this specific model [1].
- Risk: Over-reliance on auto model selection. Users might not understand why a particular model was chosen, potentially hindering learning [1].
- Myth: All premium models are gone for students. While some, like Claude Opus, were removed from direct access, others may still be available or used by auto-selection [6].
- Limit: Potential for reduced transparency. Without direct selection, students have less insight into which model is actively generating code [1].
