GPT-5.6 models missing from Codex Desktop model picker for Remote SSH projects

What version of the Codex App are you using (From “About Codex” dialog)?

26.707.31428 (build 5059)

What subscription do you have?

Pro

What platform is your computer?

• Local computer: macOS 26.5.1 (25F80), Apple Silicon
• Remote computer: macOS 26.5.1 (25F80), Apple Silicon
• Connection type: Codex Desktop Remote SSH
• Local CLI: codex-cli 0.144.1
• Remote CLI: codex-cli 0.144.1

What issue are you seeing?

GPT-5.6-Sol, GPT-5.6-Terra, and GPT-5.6-Luna do not appear in the Codex Desktop model picker when using a Remote SSH project.

The GPT-5.6 models are available for local projects on both computers. GPT-5.6-Sol also works when invoked directly through the CLI on the remote Mac. Remote access through the mobile app can use Sol against the same remote Mac.

Only Codex Desktop over SSH omits the GPT-5.6 models.

What steps can reproduce the bug?

1. Open Codex Desktop on the local Mac.
2. Connect to a saved Remote SSH host running macOS.
3. Create or open a remote task.
4. Open the model picker.
5. Observe that GPT-5.6-Sol, GPT-5.6-Terra, and GPT-5.6-Luna are absent.

What is the expected behavior?

The GPT-5.6 models should be listed and selectable for Remote SSH projects when the account and remote CLI support them, consistent with local projects and direct remote CLI usage.

Additional information

Diagnostic checks performed:

• A direct remote CLI request using gpt-5.6-sol succeeds.
• The local and remote models_cache.json files both contain all three GPT-5.6 models with list visibility.
• The local and remote model catalogues have the same server ETag.
• Fully restarting Codex Desktop did not change the Remote SSH model picker.
• Resetting the local model, HTTP, code, GPU, and session caches did not change the behavior.
• The remote SSH proxy is currently running through codex-cli 0.144.1.
• An earlier Remote SSH task was recorded with a stale cli_version: 0.141.0, despite the installed remote CLI being newer. Restarting Desktop refreshed the proxy to 0.144.1, but new Remote SSH model pickers still omit GPT-5.6.
