The review command doesn't use the normal model selection. It uses the model specified by the review_model config option.

How do I set this review_model on the cli?

Please check out this documentation for config overrides.

nothing about review_model in there.
The behavior is unintuitive

Try codex --config review_model='"codex-5.1-mini-high"' review. Alternatively, you can specify the review_model key in your config.toml if you want to use the same review model all the time. Then you can use codex review without specifying the review model on the command line.

The cli arg works, but 2 things

  1. it doesn't reflect in the output

2.

codex --yolo --config review_model='"codex-5.1-mini-high"' review --uncommitted
