Using Models
Multi uses a profile-based system to manage your AI providers and models. Each profile stores a provider, model, and configuration - and you can switch between profiles instantly.
Profiles
Section titled “Profiles”A profile is a saved configuration that includes:
- Provider - Which AI service to use (e.g., Claude Code, Anthropic, OpenRouter)
- Model - Which specific model to use (e.g.,
claude-sonnet-4-5,gemini-2.5-pro) - Settings - Provider-specific options (API key, temperature, max tokens, etc.)
Creating a Profile
Section titled “Creating a Profile”- Open the Multi panel → click Settings (gear icon)
- Click Add Profile
- Give it a name (e.g., “Claude Sonnet”, “Gemini Free”, “GPT-4”)
- Select a provider
- Configure the provider settings (API key, model, etc.)
- Save
Creating a new profile in settings
You can search for providers and models by name when creating a profile, making it easy to find the exact provider and model you need.

Switching Profiles
Section titled “Switching Profiles”Switch between profiles using the profile switcher
Click the profile name in the bottom action bar to switch profiles. Use the > shortcut for keyboard-only switching. New tasks use your default profile.
Default Profile
Section titled “Default Profile”Switch default profile for convenience
New tasks automatically use the default profile when you create them. Your last switched-to profile is automatically set as default, but you can change it in settings by clicking the star icon next to any profile.
- Create multiple profiles - One for each use case (e.g., “Fast edits” with Haiku, “Deep work” with Opus)
- Try different providers - The same task can produce very different results across models
- Use free providers for exploration - Start with CLI providers for quick iteration
- Match model to task - Don’t use Opus for a simple rename; don’t use Haiku for a complex refactor
