I agree, creating art makes you an artist, and the act of guiding an AI to refine an image into something that matches your vision is the same creative process to any other artform.
Just because it’s “easy” to prompt things by comparison to the tedium of drawn digital art does not mean you’re not an artist, and saying otherwise is just a narrative the anti-AI crowd has spun to diminish people’s work and disrespect the AI artists. It’d be like saying digital artists aren’t artists because it’s a far easier process than that of traditional artwork on canvas with oil paints (no undo, no layering, no fancy effects or infinite brush shapes). This is especially true for more involved AI artwork where inpainting and other touchups are done in post via Photoshop or whatever, it’s hardly solely just “prompting” in that instance.
Course I can somewhat understand concerns over tagging confusion and etc, and to be fair also other areas of art have their own terms, e.g. photographer, cinematographer, game developer, but they all are under the “artist” umbrella if you want a general term. No (non-disparaging) specific term really exists for those who leverage AI heavily yet given it’s such a new medium other than like “AI artist” which specifies the medium a bit more specifically similar to “traditional artist” or “digital artist”, but these are just simplified just to “artist” in terms of tagging on Derpi at least.
“Creator” may be a fair compromise but I still feel like it’s a bit silly to downplay the artistry involved. As the OP said, this is an AI-specific site, so while a blind import of tags may be a bit confusing, in practice one would understand that the “artist” term on this site is contextually referring to AI artists specifically and transform the tags if needed to whatever convention exists on other sites (e.g. if importing from here to Derpi one would replace artist:
with prompter:
and add ai content
or whatever as in theory that tag wouldn’t be needed here).
All that considered I think I still lean more towards “artist” than “creator”, but either is better than “prompter” which might as well be an insult in a place like this.
