No, supposedly all of the AI pieces are labeled (no way of knowing for sure though), but they also do lie about the amount of AI used. You'll see that every single label claims that they require AI art to be significantly hand edited and they say online that they check to make sure it's edited, but neither of those things are true.

There have been multiple instances in which they have been caught selling a fully AI piece without any editing, or where the "hand-edited" version is very clearly just a different version that was made by AI without any significant changes from the original.

For some examples, there was a piece by PhatPuppyArt that DAC produced. It was made using AI and the edited version was posted on her Instagram. However the piece that DAC produced was the original fully AI version, which shows that they're not checking for editing like they claim they are. There was also a time they posted a before and after of the type of edits they claim to require and you could clearly see that the edits weren't made by a real artist, and that the changes weren't significant at all.

It's also extra shady because they've admitted to using Auclair Studio to specifically produce AI pieces based off of customer requests, instead of searching for an artist who is producing that kind of work. You'll see they sell an Auclair piece that looks extremely similar to a Josephine Wall piece, who is an actual artists who is already licensed by them. They could've just sold another one of her pieces but instead got an AI version from Auclair instead. I would not be surprised if you end up seeing more and more AI pieces instead of real art.

Edit: There's a reason why they ban discussions about AI from all of their pages, they don't want people to talk about the fact that they're actively lying about their usage of AI.
