Codex Unavailable in Xcode 26.3 Despite Apple Intelligence Being Enabled

Hi everyone,

I'm experiencing an issue with the OpenAI integration in Xcode 26.3.

When I navigate to Xcode → Settings → Intelligence → OpenAI, Codex is marked as "Unavailable", and I cannot download or enable it.

My configuration:

macOS: 26.7.2

Xcode: 26.3

Apple Intelligence: Enabled

ChatGPT Plus subscription: Active

ChatGPT in Xcode: Available and working

Claude integration: Available and can be downloaded normally

Codex: Unavailable

I've attached a screenshot showing the issue.

I'm wondering why Codex is unavailable while Claude works without any problems, despite Apple Intelligence being enabled.

Has anyone encountered the same issue? Could this be related to regional restrictions, compatibility requirements, or an Xcode bug?

Any help or suggestions would be appreciated.

Thanks!
