As you can see, the codex cli in the remote machine is 5.5+high. But when I switch to the app and use remote connection, the displayed model is custom and I can not choose 5.5 from the menu.

TL;DR

The issue may be resolved by ensuring the Codex App and remote machine's Codex CLI versions are compatible, specifically supporting the GPT-5.5 model.

Guidance

  • Verify the Codex App version (26.422.20832) supports the GPT-5.5 model, as the remote machine's Codex CLI (0.124) does.
  • Check the compatibility of the GPT-5.5 model with the Codex App's remote connection feature.
  • Investigate if there are any version-specific limitations or settings that need to be adjusted for the remote connection to recognize the GPT-5.5 model.
  • Review the Codex App's documentation or support resources for any known issues related to model compatibility and remote connections.

Notes

The issue seems to be related to version compatibility and model support, but without further information on the expected behavior or additional context, it's challenging to provide a definitive solution.

Recommendation

Apply workaround: Check the Codex App's settings and documentation to see if there are any workarounds or configuration adjustments that can be made to support the GPT-5.5 model with the remote connection feature, as upgrading to a potentially fixed version is not explicitly implied in the issue.
