AI-generated art check thread

A dumb question but I really need know: a pixiv post with #ai is a work generated with ai? I found a really good post, but there #ai, but aiBlock from pixiv didn't hide this.

#アイ(ai) is an ambiguous tag. It can mean many things including the character's name. Use your best judgement.

Pretty sure that Pixiv's anti-AI option only blocks a couple of AI tags, rather than being a comprehensive tool that blocks all AI stuff.

Pixiv's anti-AI option only blocks things with the checkmark of being AI-generated. I don't believe it cares about tags at all.

You probably also shouldn't care about tags unless you verify they were artist-added and not user-added (see if you yourself can edit the tag)

This is surely an AI prompter.
I found many AI artifacts in one of this account's artworks (pixiv #133622264): Her eyes, star symbols on her bikini, melting lines on her left boot, and more.

Hum, I see. So for now I need to look in every corner of an image to make sure it's not AI, right?

It got flagged again, but I can't tell it is AI-Generated. Any opinions?

The Xitter bio reads "GIMP→Niji+NAI→GIMP", and all of their images on Pixiv seem to be labeled as AI-generated.

I originally had this artist muted on both Twitter and Pixiv so I assume I must've thought they were AI-generated and just went on to post a few but figure I'll ask for a second look. A few of our Russian artists have that one kind of style that AI unfortunately copies or models after a lot so it can be hard to determine if it's human or not with "the style".

See later post: forum #379788.

To follow up on this, they are posting fake 'drawing process' images via tools akin to PaintsUndo. Regardless, they missed some obvious giveaways. In the Kafka image posted on twitter, the background strings are disconnected and randomly restart at a new position after passing her body. The string 'tied' to her thigh is also not tied, just an outright AI error.

The worst giveaway is that many things (shading, proportions, outline, etc.) significantly change between the version with and without the tights, which means they either redrew the whole image (which I think is safe to rule out!) or had it passed through an AI to draw the difference.

They are trying to monetize the works, hence all this effort. This will likely catch out danbooru uploaders as this 'artist' starts noticing these signs better, so I think it would be good to put a note on their 'artist' profile.

Regarding the lines: Yes, this is the author's mistake, as she told me: “I was lazy and basically placed the lines randomly during the sketching stage.”

Proportions, shading, and contours: The problem is chromatic aberration, which was applied to different versions one by one but with different parameters (there is no standardization, everything is done manually). And yes, part of the art with the right leg (Kafka POV) was changed because the leg seemed too thick.

I am attaching link to video with the open psd file and layers:
