GitHub Copilot 将于 12 月弃用部分旧模型并提供替代方案

We will deprecate the following models across all GitHub Copilot experiences (including Copilot Chat, inline edits, ask and agent modes, and code completions) on December 14, 2026:

*Claude Haiku 4.5 will remain available to individual GitHub Copilot subscribers on annual plans. The deprecation of Claude Haiku 4.5 does not apply to these customers.

Please update your workflows and integrations to use the supported models before this date. Under default model enablement, the suggested alternatives are automatically enabled for Copilot Enterprise and Copilot Business customers unless an administrator has turned off the global default or explicitly disabled the model. If you’ve turned off the global default, you can enable access to the alternative models through their model policies in Copilot settings.

Once enabled, users will see the model in the Copilot Chat model selector in supported GitHub Copilot experiences. No action is required to remove the models after they have been deprecated.

GitHub Enterprise customers with questions or concerns are encouraged to contact their account team for assistance.
