@etraut-openai @aibrahim-oai sorry to be tagging you guys but this is quite critical. /review is broken on all versions of codex.

Thanks for flagging this. There was a brief time where gpt-5-codex was unavailable to a small portion of codex users, but that was quickly resolved. The /review feature should work for you again. Let us know if you're still seeing a problem.

We will also update the /review feature to default to the gpt-5.1-codex model in the near future.
