The Copilot in Visual Studio (Code) is not the same as Microsoft's Copilot. The former is GitHub's AI product and the latter is Microsoft's AI product. You can tell them apart because GitHub Copilot's icon is a helmet with goggles and Microsoft Copilot's icon is a colourful swirl thing.
It's wildly confusing branding not only because they're identically-named things that both repackage OpenAI's LLMs, but also because they're both ultimately owned by the same company.
I can only assume that the conflicting naming convention was either due to sheer incompetence or because they decided that confusing users was advantageous to them.
Copilot for Visual Studio (IDE) has multiple models, not just OpenAI models, it also includes Claude. It is basically a competitor to JetBrains AI.
The only good "AI" editor that supports Claude Code natively has so far been Zed. It's not PERFECT, but it has been the best experience short of just running Claude Code directly in the CLI.

Haven't tried it yet but the GitHub Copilot extension for VSCode also seems to integrate Claude, Gemini and other non-OAI stuff
And let’s not forget that Visual Studio Code (the IDE) is not Visual Studio (the IDE).
