How it works

1. Expects two config files to exist:

• ~/.claude/settings.glm.json — your GLM model settings
• ~/.claude/settings.claude.json — your Claude model settings

2. Takes one argument: glm or claude (defaults to claude)
3. Symlinks ~/.claude/settings.json → whichever source you picked

Setup

1. Create the two source config files with whatever settings differ per model:

# Example: copy your current settings as a starting point
cp ~/.claude/settings.json ~/.claude/settings.claude.json
cp ~/.claude/settings.json ~/.claude/settings.glm.json
# Then edit each one for its model

~/.claude/settings.glm.json must contains Z.ai required configs, see example below

{
  "env": {
    "ANTHROPIC_AUTH_TOKEN": "<YOUR Z.AI TOKEN GOES HERE>",
    "ANTHROPIC_BASE_URL": "https://api.z.ai/api/anthropic",
    "ANTHROPIC_DEFAULT_HAIKU_MODEL": "glm-4.5-air",
    "ANTHROPIC_DEFAULT_SONNET_MODEL": "glm-5",
    "ANTHROPIC_DEFAULT_OPUS_MODEL": "glm-5.1",
    "CLAUDE_CODE_MAX_OUTPUT_TOKENS": "10240"
  },
  ...
}

2. Save the script somewhere on your $PATH and make it executable:

mkdir -p ~/.local/bin  # or wherever you keep personal scripts
# save the script as ~/.local/bin/cc-switch-model
chmod +x ~/.local/bin/cc-switch-model

3. Make sure ~/.local/bin is in your PATH (add to ~/.zshrc if not):

export PATH="$HOME/.local/bin:$PATH"

Usage

cc-switch-model glm      # switch to GLM settings
cc-switch-model claude   # switch to Claude settings (default)

Note: Claude Code needs to be restarted after switching for the new settings to take effect.
