Research direction
Start by reproducing the duplicate entries in the Codex App model selector using the listed steps on macOS. Trace the model-selector data or labels from that entry point, determine whether the two "5.6 Luna" entries are duplicates or distinct variants, and verify that the selector shows one entry or clearly distinguishes both.

Description
What version of the Codex App are you using (From “About Codex” dialog)?
Version 26.721.30844
What subscription do you have?
Pro
What platform is your computer?
Darwin 25.5.0 arm64 arm
What issue are you seeing?
The Codex App model selector displays two adjacent entries with the identical label "5.6 Luna".
The entries provide no information that distinguishes them. It is therefore unclear whether they represent the same model duplicated in the catalog or two different model variants with incorrect labels.
What steps can reproduce the bug?
- Open the Codex App.
- Start or open a conversation.
- Click the model selector.
- Inspect the available models.
- Observe that "5.6 Luna" appears twice as two separate adjacent entries.
Session ID:
019f91b4-021c-7002-8107-6077f94e25c5
What is the expected behavior?
The model selector should display "5.6 Luna" only once.
If the entries intentionally represent different model variants, each entry should have a distinct label explaining the difference.
Additional information
The issue is visible in the attached screenshot. Both entries use exactly the same visible label: "5.6 Luna".
