About GitHub Copilot settings on GitHub.com

Configuring GitHub Copilot settings on GitHub.com

The settings apply anywhere that you use GitHub Copilot. You can configure the suggestions that GitHub Copilot offers and how GitHub uses your telemetry data.
Enabling or disabling duplication detection
Note: If you are a member of an organization on GitHub Enterprise Cloud who has been assigned a GitHub Copilot seat through your organization, you will not be able to configure duplication detection in your personal account settings. Your duplication detection setting will be inherited from your organization or enterprise.
GitHub Copilot includes a filter which detects code suggestions matching public code on GitHub. You can choose to enable or disable the filter. When the filter is enabled, GitHub Copilot checks code suggestions with their surrounding code of about 150 characters against public code on GitHub. If there is a match or near match, the suggestion will not be shown to you.
