GPT-5.5 Not Showing in Codex (Windsurf Extension) with ChatGPT Pro

Codex
1

Hello everyone,

I’ve been developing on Windsurf for a while now. Two days ago, I installed the Codex extension (version 0.5.78) for the first time. Initially, I was using it with my ChatGPT Plus account, but I upgraded to ChatGPT Pro ($200/month) specifically to access more powerful models, especially GPT-5.5.

Right now, I do have access to several models, including GPT-5.4, with different reasoning levels which is great. However, I don’t see GPT-5.5 available anywhere.

I’ve already tried logging out and back in, updating everything, checking settings, and restarting Windsurf, but nothing changed.

So my questions are:

  • Is it normal that GPT-5.5 is not available in Codex (Windsurf extension), even with a ChatGPT Pro account?

  • Or did I miss something in the setup or configuration?

My goal is really to stay within Winsurf using Codex, but with access to the most powerful models available.

Thanks in advance for your help :folded_hands:

Welcome to the forum!

You can discuss Codex-related issues here, but the official place to report them is the OpenAI Codex GitHub Issues.

I used ChatGPT to look for similar reports and found multiple variations—across operating systems, IDEs, and the Codex app—where GPT-5.5 is not listed as a model.

When reviewing those issues, the most relevant signals were:

  • Whether the OpenAI development team is actively tracking the issue
  • Whether an OpenAI developer has responded with guidance or status updates

It’s worth searching existing issues. If you find one that matches your situation, consider adding a :+1: reaction to increase visibility. If nothing aligns, open a new report with clear reproduction steps and relevant environment details.
