AI BriefingGitHub Copilot Deprecates GPT-4.1
Key point
GitHub Copilot has announced the end of GPT-4.1 support on June 1.
Details
GitHub announced that it will phase out GPT-4.1 across GitHub Copilot starting June 1, 2026.
The scope of application includes the following:
- Copilot Chat
- inline edits
- ask/agent mode
- code completions
The post raises particular questions about which model code completions will switch to afterward, noting that GitHub's usage-based billing announcement stated that code completions and Next Edit suggestions will continue to be included in all plans and will not consume AI Credits.
In other words, the feature itself is not disappearing, but it is a product change that alters the default completion model configuration of Copilot.
