The title is somewhat bait. It reads like MSFT is using less AI, while in fact it's just a force swap to Copilot.
Arguably, Copilot is GPT 5? Not sure what the CLI offers behind the covers.
Employees (at least on my team) get access to the Claude models as well when using Copilot CLI.
I disagree. As someone who just got a new Windows laptop with Copilot baked(forced) in I've tested Copilot a lot.
It. is. so. bad.
It feels like it's at least 1-2 years behind the current top models.
Copilot is the name for the harness / wrapper of MSFT products
The CLI can swap to whatever model (/models) based on your subscriptions.
The copilots on desktop or Office Apps are likely just GPT5 nano or other tiny models with cheap inference
