codex - 💡(How to fix) Fix gpt-5.1 was dropped but is still the only 5.x model available on Azure GCC High [1 participants]

TL;DR

The issue may be resolved by waiting for an update to the Codex CLI that continues support for the gpt-5.1 model in Azure GCC High.

Guidance

• Verify that the gpt-5.1 model is still listed in the models.json file to confirm it has not been removed.
• Check the official Codex CLI documentation or release notes for any information on deprecated or removed models.
• If the model is confirmed to be supported, try updating to the latest version of the Codex CLI to see if the issue is resolved.
• Reach out to Azure support to inquire about the status of the next version of the gpt model and when it is expected to be rolled out.

Notes

The issue seems to be related to the deprecation or removal of the gpt-5.1 model in the Codex CLI, but without more information about the specific error message or behavior, it is difficult to provide a more specific solution.

Recommendation

Apply workaround: Wait for an update to the Codex CLI that continues support for the gpt-5.1 model or use an alternative model if available, as the current version of the CLI may not support the desired model.
