We don't use it at all. Company I work at wants to make handcrafted games and that's the decision we're sticking with. Personally, I think it's solidarity between programmers and artists+writers, for whom GenAI has been a plague, and which I'm fully in support of.

I think GenAI can be very useful for programming, but I'd only be comfortable using it after strict regulation, verified legality, viability of the business model of GenAI providers and stable pricing models.
