Why it is worth understanding
If your work depends on one of these models, test a replacement on the same tasks and confirm account or organization access. This can surface differences in results, permissions or cost before retirement.
Conditions and limitations
This retirement applies to GitHub Copilot, not the models’ availability across provider APIs. Replacements may differ in results, cost and account permissions. We have not checked user accounts.
Important additions and corrections
