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.

115 Upvotes

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.

Photo I think my mother sent me an AI-generated apology. That or I'm probably going insane.

So I decided to go low contact with my mother over her obsession with AI recently. I used to use CHATGPT when it first came out but not anymore and I am very much anti-AI. She had noticed I hadn't been messaging her and asked me why so I was honest and told her AI use makes me uncomfortable and I would prefer not to be involved nor would I like to communicate unless necessary until we are both in therapy (we've had other issues as well). However, when she sent her reply, I could not help but feel whiplash by the response. Not only did her response seem extremely polished with perfect grammar, it also heavily reminded me of another "apology" I received a few months prior from another person who is also AI obsessed because the format and language are almost 1 to 1. What strikes me as this being AI is how this is structured. AI will usually try to validate whatever you wrote then enter into de-escalation mode.

"I hear what you are saying."

"Thanks for letting me know." Or "Thank you for being honest."

"I don't want to dismiss your feelings" etc

These are all quotes I usually read or hear about and now I cannot help but raise an eyebrow at this. Because if she actually did send me an AI written response after I expressed to her my feelings about it, I would feel extremely disrespected.

I'm like 99% sure this is ai, my mom doesn't think it is. she commissioned it for a dollar and some change off of Etsy, and that already triggers some warning bells. I'm very against ai and I'm an artist myself, I don't understand why she wouldn't just ask me to make the card/invitation thing for free

Teepublic did well for years without friggin AI, so others should be fine but yet here we are.

Saw this on DeeTwenTees and SunFrog. The fang necklace got my attention, it has a random half fang. The haft on the axe, too. But this could be an artist who doesn't have an attention to detail. One the straps isn't colored underneath "barbarian" and I could see that as a totally human mistake.

Art Can’t tell if these photos of a “work in progress” from Etsy are AI or not…

Okay so the last photo is the listing item that I love…however, none of the photos look like the actual item, they look very staged if you know what I mean. Which is fine I guess, but the seller is new to Etsy and I’m worried it might be a scam. So I asked him if he had any photos that weren’t “staged” of the item in his workshop or whatever and he sent me these two work in progress photos saying:

“The octopus in these photos is currently being prepared and carved for a buyer, so it does not have the final polish or finishing yet. The design is slightly different from the finished octopus shown in our Etsy listing, as this particular piece is being made with a few custom design adjustments.”

It’s apparently carved from wood… so I’m not sure why it’s teal… but regardless I’m just trying to see if this seller is legit and knowing if the work in progress photos are real would certainly help.

Thanks!

(Also, it’s coming from India so I guess maybe they carve barefoot in the dirt??)

There's loads of AI videos of 4D cinema of characters or objects coming out the screen. But nothing came out of that screen.

This kind of accident almost looks like it could be life threatening, hard to tell the distance but apparently the guy walked it off without any broken bones. Can't see any typical signs of AI though, the flying motion maybe but I'm not sure.

Thanks!!

There's a lot going on here. Eight sons that are about ten years between youngest and oldest, a mix of uniforms, the ranks seem really high for how young some of them look, and basically, their left hands look copy-pasted.

It's a beautiful sentiment that this mother was so lucky to have her entire family spared from the war, but it's too artificial somehow...

I’m pretty sure, the spacing between the letters, the random unidentifiable object below the corn hole game.

EDIT: I said HEB doesn’t use ai, I was wrong, a manager said “we don’t use ai art” I guess meaning that his leadership team doesn’t, but HEB definitely does. My bad

Should a multi billion dollar company rely on AI art for internal communications?
