Codex Desktop App: gpt-5.3-codex not shown in model selector dropdown

same

Same problem here on Plus plan

Signing out and back in worked for me

same on my end also.

had same issue, but when I was "logged in with api key", I did "Settings > Log out" and signed in with my personal account ($20 subscription) and now see 5.3 in model picker

Already tried that and also re-installed the app. Nothing works. Is it possible that GPT-5.3-Codex is not available in every country, yet?

Same in version 565

Change your geo😉

You mean on mac location or any VPN?

Tried re-login using US location via VPN - didn't worked. I use free subscription, no API keys.

log out, then log in again, worked for me!

log out, then log in again, worked for me!

I tried many times not worked for me.

The gpt-5.3-codex model is not yet available through the API. If you're logging in with your API key, you will not see it in the app.

Is anyone in this thread logging in with their ChatGPT subscription and not seeing the gpt-5.3-codex option? If so, please use the /feedback slash command to upload your logs and post the thread ID here.

It works now! I logged in again (5.3 didn't show up). Then I did restart Codex and the "New Codex 5.3 Announcement" Overlay popped up. I could click "Try now" and voila - now it works. Let's see how good 5.3 really is :)

Same issue. What I've tried:

• Signing in and out with a Pro account.
• Signing out, and signing in with a different Plus account.
• Quitting and restarting the Codex app.

@bart Did you add any magic sauce, other than the above, to get 5.3 to appear?

@bsmith418 As far as I know, no magic sauce added. What I mentioned is that the direct login on the website for chatgpt is a little different compared to the login I get when I sign in with Codex app. chatgpt app login only requires mail address and sends OTP via mail. Codex app login requires email address and password + sends OTP via mail. That's the only thing I found a little weird but in the end it just worked.

Hmm. I've now tried changing the Settings > Configuration > config.toml:
model = "gpt-5.3-codex"
Upon restart, when I enter a prompt, I get:

{"detail":"The 'gpt-5.3-codex' model is not supported when using Codex with a ChatGPT account."}

Okay, it's working now. One thing to watch out for: openai is happy to create a new account for you, if you enter the wrong email address. You might be thinking that you're signing into your paid account, when in fact it's just spinning up a brand new free account for you. Codex doesn't play nicely with Chrome, where most of us have our password manager, so you could be using the wrong email address.

I'm using a chatgpt pro (highest tier i guess?) account and it worked. That said, I didn't have codex installed beforehand, I literally downloaded and installed the day of release. Then I had to log out and log in again and it showed up. So perhaps uninstalling and reinstalling?

Hmm. I've now tried changing the Settings > Configuration > config.toml: model = "gpt-5.3-codex" Upon restart, when I enter a prompt, I get: > {"detail":"The 'gpt-5.3-codex' model is not supported when using Codex with a ChatGPT account."}

config.toml use GPT-5.3-Codex works. or sign out and re login.

Just needed to re-auth and the issue was resolved!

Check your environment variables, such as OPENAI_API_URL.

Signing out and back in worked for me

This worked for me too

It sounds like this has been mostly resolved and/or you have all found workarounds. If you're still seeing this, let us know.

No, it i still not working for me. I logged out and in multiple times and its still not showing codex 5.3. And as initially mentioned - even reinstalled the app.

@etraut-openai : Did you have a look at my thread-id?

Ok, I dug a bit deeper and found an old codex-cli binary that was probably being used. I deleted it and now it works. (I’m also user mweso-noxon.) I think we can close this now since it’s resolved.

Got it showing up by re-authing and restartig the app.
What still confuses me before paying for it, is the list of models not including 5.3, or are those only concerning ChatGPT and not Codex? 😅
Which feels a lil like geo-restriction, cause I live in Perú and created my OpenAI account from here, but then why would 5.3 show up in my Codex app?

Okay seems to be fine according to ChatGPT 🤓

Still doesn't work, even changing the account doesn't work. Is it because of the free subscription?

@lwmxiaobei, yes. We've limited access to our latest models (gpt-5.3-codex and gpt-5.4) to paid subscriptions.

@lwmxiaobei, yes. We've limited access to our latest models (gpt-5.3-codex and gpt-5.4) to paid subscriptions.

F*** OpenAI :)

@lwmxiaobei, yes. We've limited access to our latest models (gpt-5.3-codex and gpt-5.4) to paid subscriptions.

Is this permanent or due to high load?

@lwmxiaobei, yes. We've limited access to our latest models (gpt-5.3-codex and gpt-5.4) to paid subscriptions.

That a decision such as this can happen overnight is worrying.

If OpenAI can take such features away from people, why would OpenAI not later extend this to other aspects?

When people have become reliant and enslaved to technology, just make things more expensive for them.

Everyone, let's switch to Claude, it's no longer fun here lol

I already subscribed to claude pro yesterday

THANK YOU for allowing Codex on the free accounts up to 5.2 I just wanted to let you know that there ARE users out there who really appreciate it.

I am a paying subscriber, API and PRO, but the free accounts are proving essential to spread the word.

Codex is the absolute best by far.

Everyone, let's switch to Claude, it's no longer fun here lol

Yeah. Let's go for a company without free tier and with an inferior product... no wait...

Very confusing comments here 😄

I kinda understand the frustration, tho those things cost actual money and Claude Code doesn't work at all without paying.
Y'all trying to "blackmail" them by saying you pay someone else without a free plan/trial instead of upgrading here for the same amount is kinda hilarious 😝

@CanRau My thoughts precisely!

I have a paid subscription and encountering the same issue :/

@capfunds, we're looking into why some paid subscribers are seeing this error. We're tracking that issue in #14331. I'll post details there when I have updates to share.

If you're a paid subscriber and are not able to access gpt-5.3-codex or gpt-5.4, please look at my request here. we're looking for a few more affected users to post their user IDs. This will help us investigate.
