/model doesn't list new GPT-5-Codex models

What version of Codex is running?

codex-cli 0.36.0

Which model were you using?

_No response_

What platform is your computer?

Darwin 24.6.0 arm64 arm

What steps can reproduce the bug?

Start codex, run /model:

Select model and reasoning level
▌ Switch between OpenAI models for this and future Codex CLI session
▌
▌> 1. gpt-5 minimal  — fastest responses with limited reasoning; ideal for codin
▌  2. gpt-5 low  — balances speed with some reasoning; useful for straightforwar
▌  3. gpt-5 medium  — default setting; provides a solid balance of reasoning dep
▌  4. gpt-5 high  — maximizes reasoning depth for complex or ambiguous problems

I can run codex -m gpt-5-codex -c model_reasoning_effort="medium" and it will use GPT-5-Codex, so it's working fine with my Plus account.

What is the expected behavior?

/model should list the newest models.

What do you see instead?

Same problem

For developers using Codex CLI via API key, we plan to make GPT‑5-Codex available in the API soon

I am not using an API key but via ChatGPT Plus plan.

It works now. Did a new codex login.

Any ETA on this?
