Artbreeder and Midjourney are options Artstation offers when selecting the software used for a project, so users aren’t simply choosing to upload AI generated work because artstation can’t stop them, artstation is recognizing these as artistic software and encouraging their use on the website.
And in combination with other tools AI can be a valuable tool for artists: Like people who use ArtBreeder to design a character that they then draw or model from a reference, or the equivalent of doing that with other AI tools for other kinds of art. Or using it as part of a photobash or paintover.
I just feel like without a human touch, it’s fine for fun and regular social media, but if ArtStation is supposed to be a serious and professional website for artists it’s really not something that belongs there.
