Feature Request: Add GPT-5-Codex to Open-Source Supported Models

[stancsz]

The new GPT-5-Codex model is available through the Cline provider API, as announced here: https://cline.bot/blog/gpt-5-codex.

However, support for this model is currently missing from the open-source version of the project. This prevents the community from accessing its capabilities without using the commercial API.

Describe the solution you'd like
I would like to request that GPT-5-Codex be added to the list of supported models in the open-source version.

This would enable developers using the open-source platform to utilize the model's advanced code generation features and maintain feature parity with the commercial offering.
