Failed to fetch models - cc-switch

Quick fix

Upgrade cc-switch to v3.16.4+ for the 404 probe fix. On a Coding Plan, change the API address by hand and enter the model names yourself.

Symptom

Cannot fetch models, either when adding a new provider or on an existing one

Cause

Section titled “Cause”

This cluster holds several different GLM model list problems. The core symptom, "cannot fetch models", has two main causes: a 404 on the GLM model list probe endpoint in older versions (v3.16.3 and earlier); and using the Zhipu Coding Plan, whose dedicated API does not support a model list endpoint, so forcing the request returns 429. The cluster also holds two derived display problems: duplicate entries in the dropdown because old config was not cleaned up after renaming a model; and the 5-hour and 7-day remaining quotas shown the wrong way round on the model list page, because the old logic sorted by nextResetTime and mislabels them at the end of a cycle.

Fix

Section titled “Fix”

  1. Upgrade cc-switch to v3.16.4 or newer for the GLM model list probe 404 fix and the corrected remaining-quota display logic.

  2. On the Zhipu Coding Plan, change the API address in the config by hand to https://open.bigmodel.cn/api/coding/paas/v4 and enter the model names yourself, since that API cannot fetch a model list automatically.

FAQ

Section titled “FAQ”
Why are the 5-hour and 7-day remaining quotas swapped in my GLM model list?
A bug from the old version sorting by nextResetTime, which mislabels the two buckets in the final hours of a weekly cycle. Maintainers changed it to classify by the unit field in the response — upgrade to the latest version.
After changing the model name parameter, both the old and new models appear in the dropdown. What now?
Config updates appended without overwriting and cleaning up. That issue is currently marked stale — clean the old config by hand, or wait for a front-end fix.
Why does the Zhipu Coding Plan report 429 and fail to fetch models?
Coding Plan needs its dedicated API address https://open.bigmodel.cn/api/coding/paas/v4, and that endpoint does not support fetching a model list automatically — enter the model names by hand in cc-switch.
