What problem are you seeing?
In the Codex desktop app, when I start or use a session without selecting a project, I cannot change the model settings.
Observed behavior:
- Switching the model does not take effect.
- Switching the Intelligence level does not take effect.
- The app shows a toast error:
Couldn't update model settings. - This happens while the session is not attached to any project and the UI still shows
Work in a project.
In my screenshot, the selector shows GPT-5.5 with Intelligence set to Extra High. Attempts to change either the model or Intelligence fail with the error above.
Steps to reproduce
- Open the Codex desktop app.
- Start a new session without selecting a project.
- Open the model / Intelligence selector.
- Try to change the model or Intelligence level.
- Observe that the setting is not updated and the app shows
Couldn't update model settings.
Expected behavior
The model and Intelligence settings should either update successfully in a no-project session, or the UI should clearly explain that a project must be selected before those settings can be changed.
Additional context
I have screenshots showing:
- The
Couldn't update model settingserror while the model / Intelligence selector is open. - The About dialog showing Codex App Version 26.422.62136 (2180).
I can provide the screenshots if needed.
