python ezswitch.py

Usage

1. Launch the application
2. Select Z.ai, Claude Subscription, or Custom
3. Enter your API key and base URL (if applicable)
4. For Z.ai users: Choose your preferred GLM models (GLM-4.6, GLM-4.5, GLM-4.5-Air) for each tier
5. Click Apply Configuration
6. Just restart Claude Code - no terminal restart needed!

Pro Tips

• Use the "Show Claude Settings" checkbox to see your current configuration
• Check "Show API Keys" to view sensitive values in the settings display
• Mix and match GLM models based on your needs (see guide below)
• Settings are applied instantly to ~/.claude/settings.json

Features

• Easy GUI Interface: No command line required
• One-Click Switching: Toggle between Z.ai, Claude subscription, and custom APIs
• Advanced Model Selection: Choose specific GLM models for each Claude tier
• Secure Local Storage: API keys saved locally in ~/.claude_ez_switch/
• Real-time Status: Visual feedback for configuration changes
• Cross-Platform: Works on Windows, Linux, and macOS
• Settings-Only: Modifies only Claude Code settings.json, never system environment

Model Selection Guide

When using Z.ai, you can choose from three GLM models:

• GLM-4.6: Most capable, best for complex reasoning and coding tasks
• GLM-4.5: Balanced performance, good for everyday tasks
• GLM-4.5-Air: Fastest response time, ideal for quick queries

Strategy: Use GLM-4.6 for Opus (complex tasks), GLM-4.5 for Sonnet (general use), and GLM-4.5-Air for Haiku (quick responses).

How It Works

The app only modifies ~/.claude/settings.json - no system environment variables or shell files are touched.

Z.ai Mode

Configures:

• ANTHROPIC_AUTH_TOKEN: Your Z.ai API key
• ANTHROPIC_BASE_URL: https://api.z.ai/api/anthropic
• ANTHROPIC_DEFAULT_OPUS_MODEL: Your selected GLM model for Opus
• ANTHROPIC_DEFAULT_SONNET_MODEL: Your selected GLM model for Sonnet
• ANTHROPIC_DEFAULT_HAIKU_MODEL: Your selected GLM model for Haiku
• API_TIMEOUT_MS: 3000000 (50-minute timeout)

Claude Mode

Clears all custom settings to use your default Claude subscription.

Custom Mode

Configures any API endpoint with your custom base URL and auth token.
