Copilot subscription model mapping not applied, still calls Claude models - cc-switch

Quick fix

This is a known bug in cc-switch v3.14.1. Upgrading to v3.15.0 fixes the issue where Copilot subscription model mapping is not applied.

Symptom

Section titled “Symptom”
Error output
全部调用的是claude系列模型，并且似乎无法更改
English translation

All requests call the claude series models, and it seems this cannot be changed

Cause

Section titled “Cause”

In cc-switch v3.14.1, after connecting a Copilot subscription and configuring model mapping to a non-Claude model, the mapping configuration was not actually applied. When using Claude Code, the user found via usage statistics that all requests still called Claude series models, and modifying the mapping configuration did not change this.

The maintainer confirmed this is a bug in the software itself and it was fixed in v3.15.0. The issue is unrelated to how the user wrote the mapping configuration; it is a version defect.

Fix

Section titled “Fix”

  1. Upgrade cc-switch to v3.15.0 or later (the maintainer confirmed this version fixes the Copilot subscription model mapping not being applied).

  2. After upgrading, use it again in Claude Code and verify via usage statistics that requests now call the mapped non-Claude model as configured.

  3. If the problem persists after upgrading, reopen the original issue and provide the latest version number, reproduction steps, and relevant logs.
