post #10181606 and its children posts.

One of the hashtag for the Twitter version of this post is "#AIArt" (no AI-related tags on the Pixiv post).
I just noticed this today and was shocked. Could this mean that some of his recent arts had some AI involvement too? (The other posts don't have this hashtag after I checked them again)

I'm having a hard time detecting visual signs of generation in their art. In the post you linked, the only spot that might be an artifact is on the belt on the girl to the right (asset #34061882). Emphasis on "might"; I'm not sure it is. A lot of their recent work also has the kind of fine detail that generators can't do. If they are using ai-generation, my opinion is that they are also putting personal effort into it. AI-assisted at most.

Hi, my recent post #10187987 (sensitive) was flagged as AI. I am wondering if there is any possible feedback or advice, since the original image from pixiv looks quite clean without typical noise or abnormal curves which is common in AI generated illustration.

There are ai-artifacts in the eyes. On the left eye (asset #34309998), the sclera extends below the extent of the rest of the eye between two strands of hair. The shading the in the right eye is messy and irregular. Both are clear signs of ai-generation. The eyes are one of the places to look when searching for signs of generation; generators hardly ever get them right, especially when there's hair nearby.

Thank you so much for pointing out the trace of generator. When judging AI generated artworks I tend to focus too much on curves of torso, hair and texture of clothes, and thus neglect such obvious details.

pixiv #136848180

Having doubts due to the style.

At first glance I thought it was AI because it looked a little melty, but I think that's just the way they drew it. There are also apparent strokes in the drill hair on the right side, which you wouldn't see in generated art. Looking at their other posts, I'm spotting detail work that you also wouldn't see in ai art; the musical notes on pixiv #126414172 are one example. They're also not posting super often, so that particular red flag doesn't exist here. I'm not certain, but I think this is a human artist.

I don't see anything visually suspicious, however there is a wiki note about their work and generally those aren't written without reason, so I may be missing something.

I flagged the second one because her shoulders look weird.

i think the newer bocchi posts by jdk are ai, or at least used a significant ai base

using a noise detection tool and passing in the images, you see a lot of noise in places where they shouldnt be (notably the ceiling has a bunch of noise, usually itd be a flat color, but this usually is residue of a denoising process in most models (except some newer rf ones but those arent popular so). notably, in parts that would take more effort to get correctly with ai (the text on the tape, the hand holding the phone and the hand scanning the QR code) have much less noise, maybe indicating some manual fixing on top of it (but to a degree where most of the image is AI)

non-noise giveaways for it include the stopwatch ticks being weirdly shaped, the hand sort of stretching around the stopwatch band, a sorta impossible artifact near the top a bit to the right, it also is surprisingly low res, but not necessarily AI giveaway

i also think all their pixiv posts since 134444481 [inclusive] are AI but i leave that as an exercise for the reader

I won't comment on the detection tool since I'm not familiar with how effective they are, but I'm not a fan of the ceiling at all. The lines between the individual tiles are very messy and not uniformly thick, even when accounting for perspective. They also seem to melt into the hair of the bystanders, especially on the right side of the person second from the left in this asset (asset #34582297). Agreed also that the stopwatch doesn't look very good. These are AI images in my opinion. Edited to add that his hand on her ass looks like it melts into her skirt.
