Using GitHub Copilot language model integrationđź”—

If you have an existing GitHub Copilot subscription, you can use the Copilot models directly within HDevelopEVO without requiring additional API keys or subscriptions. Authenticate with your GitHub account, and models such as GPT 5.2 and Claude Opus 4.5 become available for all AI features.

Note

Using GitHub Copilot requires an active Copilot subscription on your GitHub account. The Github Terms of Services apply.

To get started with Copilot, see the GitHub Copilot documentation .

How to sign in:

  1. Click the Copilot status bar item (bottom of the window) or run the command “Copilot: Sign In”.
  2. A dialog appears with a device code. Click the link to open GitHub’s device authorization page.
  3. Enter the code and authorize the application.
  4. The dialog updates to show “Authenticated” and the status bar reflects your signed-in state.

Once authenticated, Copilot models become available in the AI configuration view and can be assigned to any AI agent.

To manage your Copilot authentication, use:

  • “Copilot: Sign In”: Initiates the OAuth device flow authentication
  • “Copilot: Sign Out”: Signs out and clears stored credentials

The status bar in your workspace shows the current authentication state, and dedicated commands for login/logout and model management.

Configuring available modelsđź”—

The available Copilot models can be configured in the settings under Settings > AI Assistants > Copilot > Models. The default configuration includes commonly available models. You can add or remove models based on what your Copilot subscription provides.

{
    "ai-features.copilot.models": [
        "gpt-5.2",
        "claude-opus-4.5"
    ]
}

Configuring GitHub Enterpriseđź”—

For users of GitHub Enterprise, configure the enterprise URL in the settings under Settings > AI Assistants > Copilot > Enterprise Url.

{
    "ai-features.copilot.enterpriseUrl": "github.example.com"
}
