Upcoming deprecation of o1, GPT-4.5, o3-mini, and GPT-4o
GitHub Copilot will deprecate the following models in github.com/copilot and Copilot IDE model pickers according to the schedule below:
| Model | Deprecation Date | Suggested Alternative |
|---|---|---|
| OpenAI GPT-4.5 | 2025-07-07 | OpenAI GPT-4.1 |
| OpenAI o1 | 2025-07-07 | OpenAI o3 |
| OpenAI o3-mini | (pending)* | OpenAI o4-mini |
| OpenAI GPT-4o | 2025-08-06 | OpenAI GPT-4.1 |
*The deprecation of o3-mini has been postponed. The original deprecation date was 2025-07-18. We will announce a new deprecation timeline soon.
Please update your workflows and integrations to use supported models before these dates. Copilot Enterprise administrators may need to enable access to alternative models through their model policies in Copilot settings. As an administrator, you can verify availability by checking your individual Copilot settings and confirming that the policy is enabled for the specific model. Once enabled, you’ll see the model in the Copilot Chat model selector in VS Code and on github.com. No action is required to remove the models once they have been deprecated.
GitHub Enterprise customers with questions or concerns are encouraged to reach out to their account manager for further assistance.
