# Selected GitHub Copilot models deprecated

As of today, September 1, 2026, we have deprecated the following models across most GitHub Copilot experiences (including Copilot Chat, inline edits, ask and agent modes, and code completions). Note that Claude Sonnet 4.6 is still available to individual GitHub Copilot subscribers on annual plans.

| Claude Opus 4.5 | 2026-09-01 | Claude Opus 4.7, Claude Opus 4.8, or Claude Opus 5 |
| Claude Opus 4.6 | 2026-09-01 | Claude Opus 4.7, Claude Opus 4.8, or Claude Opus 5 |
| Claude Sonnet 4.5 | 2026-09-01 | Claude Sonnet 5 |

| Raptor Mini | 2026-09-01 | MAI-Code-1.1-Flash |

Please update your workflows and integrations to use supported models. 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 deprecated models.

GitHub Enterprise customers with questions or concerns are encouraged to reach out to their account manager for further assistance.
