`codex-auto-review` doesn't exist in the API

What version of the Codex App are you using (From “About Codex” dialog)?

Version 26.422.21637 (2056)

What subscription do you have?

API Key

What platform is your computer?

Darwin 25.4.0 arm64 arm

What issue are you seeing?

Automatic approval review failed: {
  "error": {
    "message": "The requested model 'codex-auto-review' does not exist.",
    "type": "invalid_request_error",
    "param": "model",
    "code": "model_not_found"
  }
}

I manually updated my ~/.codex/config.toml to use gpt-5.5 instead of gpt-5.4.

What steps can reproduce the bug?

Use API key access, ~manually set your model to gpt-5.5~, have the guardian subagent reviewer enabled, get everything denied due to high risk.

Turns out it's just not working.

What is the expected behavior?
