Summary
GitHub is removing the GPT-5.3-Codex model from the manual model picker in its Copilot Student plan, effective immediately. The model will remain accessible through GitHub Copilot's auto model selection feature, which automatically matches each coding request with the most suitable model. This change is part of temporary reliability and performance optimization measures being rolled out across all Copilot Individual plans (Free, Pro, Pro+, and Student) as the company prepares for a broader transition to usage-based billing. The move prioritizes maintaining a performant, free experience for student learners while GitHub implements new billing infrastructure across its AI assistant platform.
