OpenAI’s GPT-5-Codex model, optimized for agentic coding, is now rolling out in GitHub Copilot

Availability in GitHub Copilot

GPT-5-Codex will be available to Copilot Pro, Pro+, Business, and Enterprise. You’ll be able to select the model in the Copilot Chat model picker from Visual Studio Code in ask, edit, and agent modes.

Rollout will be gradual and only supported in v1.104.1 or higher. Ensure you have the latest version installed and check back soon if you don’t see the model yet.

Enabling access

  • Enterprise & Business plans: Administrators must enable the GPT-5-Codex policy in Copilot settings. Once enabled, users in that organization will see GPT-5-Codex in the model picker in VS Code.
  • Pro & Pro+ plans: Enable by selecting the model in the Visual Studio Code picker and confirming the one-time prompt.
