Tools: How to Set Up Claude Code with Multiple AI Models

What this does ## Before you start ## Installing Claude Code ## Step 2: Get your API keys ## Step 3: Configure your API keys ## Step 4: Add model configurations ## Kimi for Coding ## Z.AI GLM models ## MiniMax M2 ## MiniMax M2.5 ## Dispatcher function (optional) ## Step 5: Reload configuration ## Step 6: Test ## Troubleshooting ## Command not found ## API key not defined ## Connection error ## How it works ## Adding more AI models ## RELATED NOTES This tutorial is fully based on a Reddit post for broader reach. All proper credit goes to ThreeKiloZero. Reddit post: https://www.reddit.com/r/ClaudeCode/comments/1p27ly4/how_to_set_up_claude_code_with_multiple_ai_models/ Author: https://www.reddit.com/user/ThreeKiloZero/ This guide provides a simplified approach to configuring your terminal using Fish Shell, allowing you to easily switch between different AI models when using Claude Code. The setup is also highly adaptable for .bashrc and .zshrc, requiring only minor syntax adjustments for environment variables and functions. Instead of being limited to a single AI model, you will be able to run commands such as: If you do not have Claude Code installed yet, run: Create accounts on the AI services you want to use and obtain your API keys: Store these keys in a safe place. Open your Fish configuration file: Add the following lines, replacing them with your real API keys: Add these functions to your ~/.config/fish/config.fish: If everything is configured correctly, Claude Code will start using the selected AI model. The dispatcher function selects the correct configuration automatically. Done! You now have a flexible setup to switch between AI models with simple commands.
