Your organization must be verified to use the model 'gpt-5'. Please go to: https://platform.openai.com/settings/organization/general and click on Verify Organization. If you just verified, it can take up to 15 minutes for access to propagate.

This isnt a codex issue, this is an API "issue".

GPT5 without organization verification works only without streaming mode.
If you use streaming mode it get this error.

Hi! Can you run codex login status please? You might have the OPENAI_API_KEY variable set that forces codex to use API instead of the included ChatGPT credits.

Logged in using an API key -

Yes, I have OPENAI_API_KEY set in my global env though I used codex login to go through the oauth flow.

Can you please try 0.19, we've adjusted the order of authentication sources there?

okay this worked! Thank you.

@pakrym-oai will you accept a PR for this, a config option for disabling streaming? i have one ready to go.
