GPT-5.5 not available in Codex model picker after switching to Devin Desktop

Hello,

I switched today from the Windsurf IDE to the new Devin Desktop.

When I was still using Windsurf, the GPT-5.5 model was available to me in the Codex model picker.

After switching to Devin Desktop, I installed the OpenAI Codex plugin again. The plugin itself appears to be installed and available, but unfortunately the model picker now only shows models up to GPT-5.4.

GPT-5.5 is no longer displayed as an available option.

Could you please clarify what the cause might be?

Is this a rollout issue, a limitation of the current Devin Desktop / Codex plugin integration, or is there an additional configuration step required to make GPT-5.5 available again in the model picker?

Thank you.

That’s weird it was available then not in Devin.

Have you verified your account? I know some of the latest models aren’t available until you do.
