Nah, I'm sure Google would eat their own dogfood. Right now their dogfood (Bard) doesn't seem very good compared to OpanAI, but I have to wonder if we're actually seeing what they really have. I suspect they're holding back the good stuff. They seem to have purposefully hamstrung what they've shown so far.

You don't farm out your core business. Google didn't use a rebranded Yahoo search engine in 1998, did they? They need to be a leader in AI or they will die quickly.

I have a hard time seeing why this wouldn't be the case.
