What version of Codex is running?

codex-cli 0.44.0

Which model were you using?

gpt-oss-20b

What platform is your computer?

Linux 6.16.9-100.fc41.x86_64 x86_64 unknown

What steps can reproduce the bug?

configure an oss profile, make some changes to any code base and run /review

It attempts to use the gpt-5-codex model instead of the configured model for the profile.

⚠️ stream error: unexpected status 400 Bad Request: could not find real modelID for gpt-5-codex; retrying 2/5 in 373ms…

What is the expected behavior?

It uses my configured model to review (the same one it uses for codegen).

What do you see instead?

Ideally, it should honor a review_model that is configured inside a profile, instead of only using the globally configured one
