Codex shows no model list and will not switch models

Quick fix

Turn on keeping the official login when switching to a third party in cc-switch, and make sure you signed in to official ChatGPT in Codex once.

Symptom

Section titled “Symptom”
Error output
在codex中打开不显示使用的模型列表，切换不了模型
English translation

Opening Codex shows no list of models in use and I cannot switch models

Cause

Section titled “Cause”

This is a limitation in the Codex desktop app itself (the upstream client): its model picker decides whether to show third-party custom models based on whether you are signed in with an official ChatGPT identity. With no official login state it falls back to the official default model and the list comes up empty. That check lives inside Codex and cc-switch cannot rewrite it. Separately, some users report a regression on CC Switch v3.20.0 with Codex 0.148.0 where the model has to be typed in by hand and the generated catalogue loses the Fast tier.

Fix

Section titled “Fix”

  1. Sign in to an official ChatGPT account once in the Codex desktop app, so official login credentials exist in ~/.codex/auth.json.

  2. Open cc-switch settings and turn on 切换第三方时保留官方登录 (keep the official login when switching to a third party).

  3. Confirm the third-party provider you use has local routing or route takeover enabled.

  4. Quit the Codex desktop app completely, restart it, and open the model picker again.

FAQ

Section titled “FAQ”
Why do third-party models disappear again after a while?
Usually the preserved official login state expired. Sign in to official ChatGPT once more in the Codex desktop app to restore it.
An external API has no account — why do I need to log in?
That is a gate in the Codex desktop app itself: it only shows custom models with an official login state present. The actual requests are still forwarded to the third party by cc-switch, so the two do not conflict.
After upgrading to v3.20.0 I have to type the model in by hand and the Fast tier is gone. What now?
That is a known regression in v3.20.0. For now, type the specific model name in for stable operation; the missing tier awaits a later fix.
