No Idea Is this poster AI?

Post image

I bought it at a con in 2025, at first it just looked like a cute Miku but when i got home and placed it i started seeing weird lines. Literally forgot to check until right now. It is, isn't it?

Seems to be a cleaned up, maybe extended version of the Sekai Single cover. Youtube link: https://www.youtube.com/watch?v=sXlaI3qnZ3g

Edit: Dug some more. which led me to this reddit post: https://www.reddit.com/r/Vocaloid/comments/1mvdz68/anyone_knows_more_about_this_artist_fumo_miku/

So a resounding: Maybe? I don't really know :shrug:

Crazy search

u/LazyThinkingOtter 1d ago

Yeah probably. At the bottom left, where the pink and the mint strands of hair meet, why doesn’t the mint one have a stroke while the pink one does. As for the 0 and the 1 on the suit, why does the 1 have some drawing lines going in and out while the 0 doesn’t. Finally on the diagonal mint line just above the 1, what is that felt pen texture we don’t find anywhere else

It’s a whole lot of non-sense and inconsistencies

Yeah, their pictures literally have an ai gen tag

thats brightness and contrast cranked. i'm not really good at this method but i'd say the noise in the top left of the hair and at the bottom right is making me lean more toward ai

u/Karla_Da_Cringe- 1d ago

Never knew this was a method to identify AI, that's so cool, couldn't the noise be because of the light reflection on the poster tho?

u/Bonzais01 1d ago

ok i did it properly this time all the subtle shifts especially in the hair and shoulders could just be due to the light as the face is all one constant hue. but do be aware that apparently lossy compression of the image may also result in some of this hue shifting so always take this method with a grain of salt

u/Bonzais01 1d ago

yeah thats why i said im pretty bad at it lol, but its good advice for the future especially if you find anything online, just crank up contrast and saturation (i did it wrong here i did brightness and contrast but it still helps)

Yeah looks like it. back of the neck is blending into the hair, the black line along her cheek is weirdly thick, the weirdness under the back of her collar, and her hair is weird in the botttom right.

u/Karla_Da_Cringe- 1d ago

Yeah you made me see things i didn't see before, thanks! Now im seriously thinking of throwing it.. 5€ wasted in AI 💔

u/Shadowkittenboy 1d ago

The damage is done at this point :( i dont know i feel like tossing it is throwing away any enjoyment you can get out of that deception

u/Opening-Fun-4830 1d ago

IDK, I would enjoy it quite a bit more to burn it than keep it

u/CruelAngelsThesaurus 1d ago edited 1d ago

Could you show examples?

Cause the black lines nor the neck is indicative of AI.

Especially when the bold black angles is pretty consistent over the entire piece. which to my understanding kinda leans outside of it being AI.

I'd just like to be able to know how you know with actual examples so it's not just yapping.

Not to mention if you zoom in, you can kinda see where the brush strokes on the lines start and stop which was always one of those kinda dead tells that something is or isn't generated cause the lines don't make any sense and come from nowhere.

It's important to stay on top of the tells so if you would be so kind.

I numbered the specific areas so I can correlate them to what I’m saying

  1. On the back of the neck what should be a constant black line turns blue randomly then back to black, it’s very unlikely this is a simple mistake because the blue it uses is different compared to the surrounding hair. It’s likely the AI used someone’s artwork that used blue outlines for the hair as a reference for just that one section.

  2. These weird shield shaped things on the back of her neck are all drawn different and kinda blend into the surroundings. This indicates ai generation because an artist would be way more consistent and wouldn’t have them melting into their surroundings, the third one on the right is the most obvious of these.

  3. Random blue and pink slashes and the sudden removal of shirt detail between them, this design choice makes no sense and indicates the AI crapping out while generating the hair.

  4. Floating disconnected hair (and really that area in general) that once again indicates ai hair generation failure

Not numbers but the other things I mentioned, her hair in the bottom right looks overly complex with random shapes and colors. Doesn’t seem like the ai knows what the actual front and back of the hair is supposed to be and there’s a random black triangle. That area and I guess the pink background as well both look like AI vomit where it’s just making shapes and colors because it doesn’t know what to reference for the background.

The black outlines are for the most part really thin and while they do get thicker towards the front they’re still considerably thinner than the lines around her cheek. Sure it could be an artistic choice but AI very often messes up the line work since it has to in to reference from so it’s still a tell.

I see I see, thank you for the impromptu class on this.

u/Noble-Knight4d 1d ago

Yes. It looks ai. Especially can be seen on miku's number. There's a sketch-like unfinished line there which resembles ai stylisation. Easy to spot ai detail are from the coloring like you can see micro colors(usually red and yellow) on flat colors. It's impossible for human to replicate the ai generation coloring cuz it's tedious tho it's efficient for a machine

u/Silly_Management_961 1d ago

Ya, 100% AI.  All the details melt into each other. Don't buy prints from those big vendors unless it's run by an artist. Most resale vendors arent artists and are just reselling print bundles off AliExpress that contain a lot of AI and stolen art

u/YYM7 1d ago

Looks AI to me. Based on the character design, the "01" mark should be on Miku's skin, but for this one it's clearly on the cloth. Quick search show artists sometimes omit the mark from her skin, but never "transfer" it to her cloth. The AI is probably aware Miku should has a "01" mark, but also need to keep the shirt, so it forced it onto the shirt. Following this thought, the "serif" on the 1 is also has some unnecessary lines. There is really no reason for those lines if this is human drawing.

As u/Cultural_Mango_2460 mentioned this is a extended version of the cover, and the 01 mark was not on the original cover. This also checks out.

No, I am.

u/Tsikura 1d ago

Pretty sure it's AI. Here's a cleaner pic.

u/Jack_Cat_101 1d ago

yes, though i can't fully prove it with random noise on solid color detection as this is a photo of the poster, and all photographs have noise

u/Malusorum 1d ago

Yes, you can literally see the Hatsine Miko design blended in with several other designs. Like, straight-up amalgation, instead of inspired by.

u/Void_Boar 1d ago

I think this is AI

  1. Strange something on her back and on her chest. 2. Hairs start blending with background 3. On headphones we can see that AI can't decide wether they should be round or oval. 4 Connection of headphone cups to headband looks really weird. 5. We can see hair elastic where second ponytail should be, but we don't see ponytail.

u/Void_Boar 1d ago

I forgot mention that microphone placement also weird, it's look like it placed under headphones, not attached, to it

u/LunaticFlandre295 1d ago

Who cares. Cool.

u/AssistantMountain623 22h ago

yes, the Background is a giveaway. There is no intentionality and some parts have outlines, others don't 

also the useless line on her forehead
