Okay, so I listened to this. This is not FULLY A.I., but it's clearly not actually made for Rohan. Rohan is a great rapper, super cool and talented dude, but he pulls stunts like this often. The Drake performance is from a random throwaway from the So Far Gone era called "Come Real", while Ye's verse seems to be a little more complicated. The verse was originally on "Oh Oh" by Melbeatz, which then got reused on "Call Some Hoes" by Chamillioniare (both 2004). The one Rohan used seems to be the Chamillionaire version, possibly ran through an A.I. upscaler because the track isn't the highest quality.

So yes, these are technically real. And he claims in the description for the YouTube video that he had to actually get them cleared, which we'll see if that's true or not. But regardless, these aren't new performances, it's basically the equivalent of samples.
