It has almost definitely seen a lot of coding problems so I would expect "write a function to binary search a sorted array" to output the intended result. I don't think anybody expects it to come up with algorithms it hasn't encountered.

I found the whole UI/sandbox they created the most interesting part. Now don't get me wrong, the tech is certainly great and all, but I really didn't had the feeling I watched/learned more than I already knew from what was shown with Github CoPilot, although I was kinda impressed, if it really is as simple as they stated, at how it is able to adapt to new apis.

It's a shame they only limited the demo to relatively simple instructions.

I don't believe the model was trained on Google interview answers, sadly.
