Github Copilot Model Switcher

Quickly switch between GitHub Copilot models with keyboard shortcuts.

Setup

1. Install the extension
2. Set your preferred model IDs in VS Code settings (optional — defaults are pre-configured)
3. Bind switchToModel1 and switchToModel2 to your preferred keys in keybindings.json

Configuration

The extension exposes two generic model slots. Next time you want to swap a model, just update the setting — no keybinding or code changes needed.

Option A — VS Code Settings UI (easiest)

1. Open Settings (Ctrl+,)
2. Search for copilot model switcher
3. Set Model1 Id and Model2 Id to your desired model IDs

Option B — settings.json

{
  "github-copilot-model-switcher.model1Id": "claude-sonnet-4.6",
  "github-copilot-model-switcher.model2Id": "gpt-5-mini"
}

Keybindings

Add to your keybindings.json:

[
  {
    "key": "alt+f11",
    "command": "github-copilot-model-switcher.switchToModel1"
  },
  {
    "key": "alt+f12",
    "command": "github-copilot-model-switcher.switchToModel2"
  }
]

Finding Model IDs

1. Open Command Palette (Ctrl+Shift+P)
2. Run: Discover Copilot Commands
3. Check the Copilot Commands output panel — all available model IDs are listed there
