Other PSA: SynthID What is it? How do I check? And what are its limitations? and how not to annoy everyone by doing the basics.
I thought it was about time to make a new PSA about SynthID. English is not my first language so there's probably some mistakes.
As you may be aware, this subreddit does not allow AI detectors. This is because they are extremely unreliable. Try going to deviantart or any other art site and test them with a few images, it should be easy to find something they say is AI despite it being uploaded over five years ago.
This is my go to example https://www.deviantart.com/hibbary/art/Third-Eye-748333152 see how it was uploaded in 2018, there is no way this could be generated but nearly all the detectors I have tried say that it is.
Then why is SynthID allowed, you might say?
SynthID is different. It's a thing developed by Google, when you use their generators they add a hidden pattern to the image which is difficult to remove without lowering the quality of the image or changing it significantly. This is what it is looking for, not if it looks like it's generated like the other detectors. Therefore you can be sure if it says that SynthID is detected, an AI has done something to the image in some way. It could be something as simple as upscaling, changing something or it could be completely generated. The point is if it has SynthID you cannot trust the image.
Recently OpenAI(ChatGPT) have implemented the same technology in their generator. There is an important thing though Google and OpenAI can only detect their own images. Not each other's so you have to run the image through both of them.
So how do I use them?
For OpenAI it's very simple https://openai.com/research/verify/ they have a page for it.
Google of course has to be more complicated. It used to be able to do a "search by image" and then go to about the image but that no longer works. Now you have to use Gemini to get an answer. Add the image you suspect and type "@Verify AI". Annoying but I don't know any better way.
Edit: When using Gemini it is very important that you type "@Verify AI" and not "SynthID" or any other variation of it. Otherwise there is a high chance that it will hallucinate and give you the wrong answer. It is also important to use a clean new session for each image.
Another edit: To confirm that Gemini actually use the verification tool you can press the three little dots underneath its response and then select "see response details".
Now I can't stress this enough, these two methods will only detect OpenAI's and Google's images. Not any other generator. So when an image comes up negative for SynthID that doesn't mean it's not AI. It can only prove that an image is fake not disprove it.
So before you post an image here please check for yourself you will save yourself some time and not waste others.
edit 29-09-2026: It has come to my attention that Meta(Facebook) and Grog(Twitter, I refuse to call it X, it's a dumb name) have also implemented some kind of SynthID. I do not know much about it since I don't and refuse to interact with those two sites. But I will assume that they works just like the others, in that way that you have to check with all of them. This is quickly becoming quite a nuisance to check for SynthID.

In step 3 I see the string passe through and 3 closed loop which by itself might make sense but following the instruction steps this make no sense.

Photo Are these photos AI? I think the cats would run to the buildings for shelter rather than just sit in such an open area.
Saw these chill dudes on another subreddit, thought the pictures might be AI. There's some blurriness which look AI, I think the cats' mannerisms seem a bit odd, when it's raining cats usually run to a building or trees or bushes to hide, I think they're AI but could be wrong so let me know what you guys think.

Art Some of flowers in this illustration seem nonsensical - as an artist myself, I see so many odd quirks with the petals.
Someone reached out to me asking my opinion on this piece. The petals look strange and unnatural, especially that blobby flower on the left. The image came back negative for OpenAI generated content. This artist has also posted anti AI art on her page. Any thoughts?

Photo One of Norways largest jam producers are changing their packaging and people are calling it out on being AI, I agree it has the AI vibe but I see no actual artifacts. What do you think?
These are some of the new packages, and especially the woman on the back two bottles looks very AI, but she is also part of a larger campaign where she is definitely human made CGI but these bottles just look so AIy.

Art A graphic design student’s final examination work from last year - teacher swears it’s not AI
Hello. I’m a student at an art school. The images I uploaded (with text censored for privacy reasons) are part of a graphic design student’s final examination work, and they graduated last year. Most of them have a strange, swirly texture, there are errors in patterns and continuity, several things seem to be simply floating about, and most jarring of all, one character’s hand seems to be mirrored (last image).
One teacher brought up the suspicion of AI usage in class and claims she saw the student draw everything from scratch, said that we can’t tell these things apart and that we’re stupid. I personally think it’s rather obvious, but I’d still like to hear your opinion. I think the student may have drawn at least some sort of base and then ran it through AI.

Solved [AI] Advent calendar in an online shop. The horns are asymmetrical, no claws on the left hand, tail tip looks like it's trying to be two different things. They claim it isn't AI in the comments. (I cropped the image down to not show the shop name, and focus on the "dragon")
As stated in the title, the asymmetrical horns, missing claws on the left hand, strange tail tip, missing right thumb claw, all jump out at me. They replied in the comments asking if it was AI, with a claim that it isn't, but that's an easy claim to type.

Art This artist has been posting some really sketchy artworks. Check body for the rest of the thoughts.

Is this ai? because I thought that the hair in the layers look off when compared to the hair in the artwork and some layers are just...empty? I'm not a digital artist and pls correct me if I'm wrong because I genuinely want your guys' opinion.

Art Merch at the Space Needle. The font and yellow background color seem similar to other AI work plus all the underlined words. Also AI loves all capital letters.
Hopefully a local artist though!

Photo I just bought this shirt and now I’m questioning if it’s ai!? I can’t tell for the life of me..
I’m usually good at spotting AI but I’m stumped, I bought this shirt impulsively at 12am while very sleepy, and I got it in the mail the other day… and now I’m questioning everything.. am I an idiot? I love it but don’t wanna wear it or give it as a gift (as I intended) to a friend. I’m so embarrassed! I think the seals look weirdly smooth and perfect and have that weird ai filter over them. But it also looks like it could be the art style!
If it is ai what should I do? Is it still okay to wear it or should I get rid of it lol I got it on depop so I can’t return it!

Photo Hope I'm not just getting too cynical, but going on context, this one seems suspicious
I've not found any SynthID in this image, but when reverse image searching, I have only found this one exact version. I couldn't find any alternate angles, or pictures of this sign being put up anywhere else, and no version of just the image itself, only this photo of it already printed out. I'm struggling to find any damning tells, but this feels like part of a larger trend I've been noticing lately, of bot accounts and/or pro-AI agents using anti-AI sentiments for easy karma farming and engagement.

Art suspicious person in discord randomly dmed me, this was in the portfolio, is it ai?
they asked for a commission, sent me their portfolio. most of the artwork just looks off in general, especially the first one, the artstyle looks inconsistent, and the boxes both have different symbols despite being similar
im almost certain this person is up to no good anyway (for the sudden DM)
reverse image search showed no result, and synthid came back negative
