How can I adjust this to use a chat model? It seems to be in streaming mode, and the configuration in cc appears not to take effect.

Cause

Section titled “Cause”

This report is from cc-switch v3.19.1 and includes only a screenshot, with no specific error or logs sufficient to confirm the cause. The maintainer said that 4.0 rewrote local routing and Claude Code configuration writing, and fixed several format conversion issues, including OpenAI Chat Completions. The available information therefore cannot determine whether the issue is in the configuration or protocol conversion.

If the issue still reproduces after upgrading to 4.0, the maintainer recommends providing the cc-switch version, the API format selected for the provider, whether local routing is enabled, and logs from the relevant time.

Fix

Section titled “Fix”

  1. Retry after upgrading to 4.0; the latest download URL provided by the maintainer is https://github.com/farion1231/cc-switch/releases/latest.

  2. If it still does not work, submit the cc-switch version, the API format selected for the provider, whether local routing is enabled, and logs from the relevant time in ~/.cc-switch/logs/cc-switch.log.
