As said on 25 of march Github is using real world data to improve models. The indexing starts on 24th of april and is an Opt-out policy. No message has been sent to me about this change and didn't really hear about this anywhere yet.
I don't use Github anymore but while still using VScode time to time, I almost missed this message. The exact message that are being indexed is:
"
-
Outputs accepted or modified by you
-
Inputs sent to GitHub Copilot, including code snippets shown to the model
-
Code context surrounding your cursor position
-
Comments and documentation you write
-
File names, repository structure, and navigation patterns
-
Interactions with Copilot features (chat, inline suggestions, etc.)
-
Your feedback on suggestions (thumbs up/down ratings)
" so more or less the whole code base could be indexed quite quickly.
If you werent aware of this change I encourage you to read the official statement by Github:
