Copilot isn't a model, you can use Claude via Copilot.
Neither is Copilot. The title explicitly mentions Claude "Code".
I don’t think that’s what they were insinuating. Claude Code internally, Copilot for customers.
Copilot is anything you want it to be inside Microsoft. Heck even Office is Copilot nowadays.
Both use the same models. But Claude Code has something special that Microsoft doesn't have in Github Copilot CLI.
