Enable Premium AI Models in GitHub Copilot

Step-by-step troubleshooting guide for accessing Claude Sonnet 4 and other advanced models.

Common Issue: Premium Models Not Visible

If you can't see premium models like Claude Sonnet 4 in your GitHub Copilot extension, the most common cause is organizational-level restrictions that are enabled by default.

Important: Premium models are often blocked at the organization level by default. You'll need to check both your account preferences and organizational settings.

Step 1: Access GitHub Copilot Extension Settings

  1. Open Visual Studio Code
  2. Go to the Extensions panel (Ctrl+Shift+X)
  3. Find the GitHub Copilot extension
  4. Click the gear icon next to the extension
  5. Select Extension Settings or look for Account Preferences

Step 2: Check Account Preferences

In the extension settings, you need to ensure you're signed in with an account that has premium model access enabled:

  1. Look for account selection options
  2. Make sure you're using an account that doesn't have premium models disabled
  3. If you have multiple GitHub accounts, try switching between them

Step 3: Configure GitHub Copilot Features

The key step is to visit your GitHub Copilot features settings:

  1. Navigate to: https://github.com/settings/copilot/features
  2. Review the model availability settings
  3. Look for Claude Sonnet 4 and other premium models
  4. Ensure they are not blocked or disabled

Step 4: Organization-Level Settings

If you're part of an organization, premium models might be disabled at the organizational level:

Default Behavior: By default, many organizations block premium models to control costs and usage. This is a common security and budget management practice.

Step 5: Verify Model Access

After making changes:

  1. Restart Visual Studio Code
  2. Open the GitHub Copilot chat or inline suggestions
  3. Look for model selection options
  4. Verify that Claude Sonnet 4 and other premium models are now available
