Extension: GitHub Copilot

Unlike Visual Studio Code, in VSCodium, Copilot features are disabled and not configured.

Update your settings

In your settings, sets:

"chat.disableAIFeatures": false,

Configure product.json

You need to create a custom product.json at the following location (replace VSCodium by VSCodium - Insiders if you use that):

• Windows: %APPDATA%\VSCodium or %USERPROFILE%\AppData\Roaming\VSCodium
• macOS: ~/Library/Application Support/VSCodium
• Linux: $XDG_CONFIG_HOME/VSCodium or ~/.config/VSCodium

Then you will need to follow the guide Running with Code OSS with the product.json file created previously. You will need to add the properties: trustedExtensionAuthAccess and defaultChatAgent.
