Is there a way to use the GPT-5.2 Pro model directly in Codex CLI?

Hi and welcome to the community!

Sorry for the late response!

For this particular case my recommendation is to split the task into two steps. First, use /plan to create the plan and then execute it in the second step. You will be asked to clarify open questions and confirm execution before this second step starts.

Since GPT-5.3-Codex has just been released I highly recommend using this model.
