What issue are you seeing?
In the Codex Desktop app, a chat that is not attached to any project cannot be switched from GPT-5.4 to GPT-5.5.
When I open the model selector and click GPT-5.5, nothing changes: the selection/checkmark remains on GPT-5.4. GPT-5.5 is visible in the menu, but clicking it has no effect in a non-project chat.
However, when I start or open a chat inside a project, GPT-5.5 can be selected normally.
Steps to reproduce
- Open the Codex Desktop app.
- Start a new chat without selecting
Work in a project / without attaching a project.
- Open the model selector.
- Click GPT-5.5.
- Observe that nothing changes and the selected model remains GPT-5.4.
- Start or open a chat inside a project.
- Open the model selector and click GPT-5.5.
- Observe that GPT-5.5 can be selected normally in the project-based chat.
Expected behavior
GPT-5.5 should be selectable in both:
- chats with a selected project
- chats without a selected project
Actual behavior
In non-project chats, clicking GPT-5.5 has no effect and the chat remains selected on GPT-5.4. In project-based chats, GPT-5.5 can be selected normally.
Environment / account

Additional information
The attached screenshot shows the model selector where GPT-5.4 remains checked while GPT-5.5 is visible as an option in a chat where no project is selected.
