Interesting, I'll have to check it out.
Of the available models under copilot everyone seems to agree that the claude models are by far the best coding models, so I've been sticking with claude 4 and now 4.5. That being said, even the models available on the free plan are really capable, but when I ran out of credits a few days ago I didn't hesitate to slap down my credit card for the upgrade.
As just another example, what started with a minor refactor of my mksservo42c python code ended up with a complete refactor with comprehensive install guides and best practices. Then I set it loose on creating a version for arduino and it did not disappoint.
I did all this just this morning while I was waiting for a friend to arrive.
And that started with my copying over a wiki page about the servo as source material for the agent to work with, and to say it took the ball and ran with it is an understatement.
