Unfortunately it seems like it's greater than 0...
If we ignore the procedurally generated NFTs created from mixing and matching various assets and go with ones where AI is the selling point, we're left with a few notable ones: Sophia, a robot w/ some low-level AI sold a single piece for 689k USD [^1]. Botto, a VQGAN-based algorithm sold a single piece for 430k USD and has sold multiple other pieces for tens to hundreds of thousands of dollars. Slightly more modest are some other projects like Metascapes [^3] and Eponym [^4], which produced some really tedious pieces that managed to sell for 3.5k USD and 10k USD respectively. That said, the Eponym piece seems to be some sort of self promotion, so maybe we can say that the actual prices for these collections are somewhere in the fraction of an ETH range if they can be sold at all.
Honestly, only the Botto piece is remotely interesting to look at, and even then I feel as if the blurred, "dreamy" aesthetic that seems to be in so many different AI painting approaches (style-transfer, VQGANS, DALL-E, maybe others I'm not aware of). I think it was more interesting back when we could pretend that these were the electric sheep at the fringes of some deep-sleeping latent intelligent potential but now they just feel kinda arbitrary and lacking deliberation. I absolutely love the field and think these researchers have done tremendous work, but I feel as though all the lay news attention is on the art, and not on the algorithm that generated it. The fascinating thing is that we have a machine that can produce novel something from words or basic ideas and that the output's content retains these ideas, not so much that art itself has that much compositional or stylistic merit.
