What issue are you seeing?

  Codex just got an upgrade. Introducing gpt-5.3-codex.

  Codex is now powered by gpt-5.3-codex, our most capable agentic coding model yet. It's built for long-running, project-scale work, with mid-turn steering + frequent progress updates so you can collaborate while it runs (and it's faster too).

  You can keep using gpt-5.2 if you prefer.

  Choose how you'd like Codex to proceed.

  1. Try new model
› 2. Use existing model

Seemingly 1/4 times or something I open codex, I see the above message and have to select "No, I still want to keep using the same model I've already said I want to use".

I think maybe this was supposed to only show once per user, but instead it seems to reappear. Seems to happen both when using codex in directories where you've used it before, and new directories.

What steps can reproduce the bug?

Open codex with gpt-5.2 set as your current model multiple times either in the same or different directories.

What is the expected behavior?

The message is presented once (or less times than currently at least) per user.

I'm now running my own fork of Codex as this message is getting in the way so much, could you please at least decrease the frequency of this? It keeps asking me to change the model and I can't find any workaround except patching the code itself, but I also don't want to keep maintaining my own fork just because of this bug.

@embedding-shapes, this message should appear only once. The preference is saved in your config.toml file like this:

[notice.model_migrations]
"gpt-5.2" = "gpt-5.2-codex"

Can you confirm that this is appearing in your config file? By any chance, are you modifying or deleting your config?

Many thanks for replying @etraut-openai

This is what my config has right now re notices:

[notice]
hide_full_access_warning = true
"hide_gpt-5.1-codex-max_migration_prompt" = true

[notice.model_migrations]
"gpt-5.2" = "gpt-5.2-codex"

And yes, I'm still seeing that maybe 10-20 times a day, starting codex 30-40 times, I'd estimate.

I always run codex with codex --sandbox danger-full-access --dangerously-bypass-approvals-and-sandbox --search FWIW, I see I missed explaining this in the initial description. I've confirmed other config values are used from the config, so doesn't seem to be the case the config cannot be read somehow and therefore using default values, other things are used correctly.

Thanks for confirming that you have the "gpt-5.2" = "gpt-5.2-codex" line in your config file. That should prevent the message from showing up.

I'm not able to repro the problem, and we haven't received reports of this from other users, so there must be something specific about your configuration that's causing this. You may need to do some debugging on your own. Codex is open-sourced, so you could clone the repo, build it, and ask codex to try to help you debug the problem. Let us know if you find the cause.

I get the prompt when using api key authentication and probably shouldn't be.

I just want to say I'm also getting this. Also, may I ask what "gpt-5.2" = "gpt-5.2-codex" is supposed to mean? To be clear, I'm currently mostly using gpt-5.2 (not codex) so that's what I have selected.

If you see "gpt-5.2" = "gpt-5.3-codex" in the [notify] section of your config file, that means "the user has already been asked whether they want to upgrade from gpt-5.2 to gpt-5.3-codex". If present, you should not see an introduction message or upgrade prompt if your configured model is gpt-5.2. If you were to then change your selected model to gpt-5.2-codex (by adding the config line model = "gpt-5.2-codex") and relaunch, you'd see the introduction message and upgrade prompt, and regardless of whether you pick "yes" or "no", you'd see that "gpt-5.2-codex" = "gpt-5.3-codex" is added to the [notify] section.

Let me know if that differs from what you're seeing.
