It is said that 0.34 version doesn't support Azure OpenAI now, so have to rollback to 0.31 version.

@DevOps-zhuang I think you put a solution here right? Did you get it working?

HELIOPOTELICKI · 10 months ago

Same problem here, only work on "npm install -g @openai/codex@0.31.0" version

evmin · 10 months ago

And looks like 0.31.0 is no longer picking up model deployment from "model" field.

This one fails:

model          = "gpt-5-2025-08-07"

I think this has been fixed. If you're still seeing this with the most recent version of codex, please open a new bug report.
