Model list is empty; Codex cannot select the DeepSeek model

Quick fix

Upgrade to CC Switch 4.0 and reapply the DeepSeek preset; model list display in the Codex desktop app also depends on its version support.

Symptom

Section titled “Symptom”
Error output
模型列表中显示模型为空
English translation

The model list appears empty.

Cause

Section titled “Cause”

These issues describe cases where Codex can already chat normally through DeepSeek, but the model selector appears blank or shows “Custom.” The maintainers said support for third-party model lists in the Codex desktop app is incomplete, and display depends on the Codex version. The model can therefore work even when the selector displays incorrectly.

The maintainers said CC Switch 4.0 rewrote how Codex configuration is written and added a complete model catalog to the DeepSeek preset. Earlier reports also mentioned that keeping the official ChatGPT login, enabling “Keep official login when switching to a third party,” and local routing might affect desktop display. These suggestions coexist with the later 4.0 configuration fix; the issues do not show that they apply in every case.

Fix

Section titled “Fix”

  1. Upgrade to CC Switch 4.0 or a later version, then select or apply the DeepSeek preset again and check the Codex model list. The maintainers said the newer version includes a complete model catalog.

  2. If third-party models still do not appear in the Codex desktop app, first sign in to an official ChatGPT account, enable “Keep official login when switching to a third party” in cc-switch settings, confirm that DeepSeek local routing is enabled, then fully quit and restart Codex.

  3. If the issue persists, provide the maintainers with the CC Switch and Codex versions and specify whether you use Codex desktop or the command line. If needed, attach config.toml with the Key redacted and the ~/.cc-switch/logs logs.

FAQ

Section titled “FAQ”
What does it mean if the model list is empty but DeepSeek still responds normally?
Users in the issues reported that requests received normal answers from DeepSeek while the list was empty. The maintainers noted that the Codex desktop app has incomplete support for model lists, and display depends on the Codex version.
How should I reconfigure DeepSeek after upgrading?
The maintainers recommend adding or applying the DeepSeek preset again in CC Switch 4.0 or later. The preset includes model names, context windows, and image input information for the model catalog.
What should I do if the model disappears after changing the language to Chinese or signing in to the official account again?
Related reports said the model list became abnormal after changing the language to Chinese, restarting, or signing in again. The maintainers recommend retesting with CC Switch 4.0. If the issue still reproduces, provide version information, config.toml with the Key redacted, and the ~/.cc-switch/logs logs.
