Am I missing something? The article seems to suggest it works via hidden text characters. Has OpenAI never heard of pasting text into a utf8 notepad before?

The arstechnica article speculated it was more of a pattern of words thing.

I think it is lies, and doesn't exist or work anywhere near as good as they claim. Or, its incredibly easy to bypass.

Research on this topic exists, and it is possible to alter the output of an LLM in minor ways, that statistically "watermark" the results without drastically changing the quality of the output. OpenAI has probably implemented this into ChatGPT.

https://www.youtube.com/watch?v=2Kx9jbSMZqA

I think the tool exists, and is (at least close to) as good as they claim it is. They can't release it, because once the public can tell with high accuracy whether ChatGPT wrote some text, another AI can be developed to circumvent detection from this method, making the tool useless.

[-] CameronDev@programming.dev 11 points 3 months ago

That is a long video, is the paper published somewhere?

Im willing to accept that you can statistically "watermark" the text, but I'm not convinced that it would be tamper resistant, which is a large part of what makes a watermark useful. If it can't survive an idiot with a thesaurus, its probably not gonna be terribly useful.

[-] Womble@lemmy.world 7 points 3 months ago

It can likely also be defeated by adding "In the style of X" to a prompt, changing the distribution and pattern of the responses.

[-] JackbyDev@programming.dev 2 points 3 months ago

...but that output is also from the AI so it would still be watermarked lol

I think it exists and works but that its simply not in their best interest to have people use it and be found out that they used chatgpt, for OpenAI's business/profit potential. I have nothing to back it up but have just lost all faith in OpenAI.

[-] CameronDev@programming.dev 10 points 3 months ago

Im willing to believe it exists, but not that its any good. 99% is a crazy accuracy claim.

[-] pup_atlas@pawb.social 16 points 3 months ago

I van totally believe that it detects AI generated content 99% of the time, that’s trivial. What I really wanna know is the false positive rate. If I write a program that flags everything, it’d have a 100% hit rate. It’d also however have a crazy high false positive rate.

[-] Womble@lemmy.world 5 points 3 months ago* (last edited 3 months ago)

Yup, noticable that they use the phrase "99.9% effective". Effective doesnt have a defined meaning in this contect, unlike accuracy, sensitivity or specificity, so that smells of missleading PR speak to me.

[-] Orbituary@lemmy.world 4 points 3 months ago

Especially if the claim that it's undetectable by humans.

[-] originalfrozenbanana@lemm.ee 5 points 3 months ago

They sell the cheating tool and the detection software

Not to mention that it would be extremely difficult to implement an effective watermark on text below a certain size

There are hundreds of thousands of pixels in an image where you can hide a watermark, but in a text output of a paragraph or less there are only a couple hundred characters.

How precise is the watermark? Is it a specific sequence of characters? Is it a sequence of words? A number of characters in a row? Non-print characters?

How precise the watermark is will determine how easy it is to get around. I imagine some of the most important uses to detect would be twitter/social media influence bots where the output length is only 140 characters or less. I find it hard to imagine a watermark on output of that size being effective or reliable.

[-] MagicShel@programming.dev 88 points 3 months ago* (last edited 3 months ago)

Am I the only one who rewrites most of ChatGPT's output into my own words because it's "voice" is garbage anyway? I ask it to write me a cover letter and that gives me a rough outline and some points to make, but I have to do massive editing to avoid redundancy, awkward phrasing, outright lies, etc.

I can't imagine turning in raw ChatGPT output. I had one of my developers use Bing AI to write code and submitted that shit raw and it was immediately obvious because some relatively simple code has really weird artifacts like overwriting a value that had no reason to even be touched.

[-] lowleveldata@programming.dev 28 points 3 months ago

Idk it looks good to me. Straight to the main branch you go.

[-] ValenThyme@reddthat.com 6 points 3 months ago* (last edited 3 months ago)

i use it to make outlines which are usually very good and then I use the class materials to flesh out the outlines in my own words. All my words but ChatGPT told me what to include and in what order.

[-] MagicShel@programming.dev 5 points 3 months ago

That's valid. And I'd be surprised if that could be watermarked.

[-] cyberpunk007@lemmy.ca 5 points 3 months ago

For me I find it sounds too much like a marketing person or something I'd see in an ad or a website so I "dumb it down" a bit to make it not sound too corporate. Sometimes telling Chatgpt to do so fixes this though.

[-] JeeBaiChow@lemmy.world 4 points 3 months ago

Lol. AI gonna take over the developers job. Like that's even close to happening.

[-] Thorny_Insight@lemm.ee 7 points 3 months ago

Few years ago the output of GPT was complete gibberish and few years before that even producing such gibberish would've been impressive.

It doesn't take anyone's job untill it does.

[-] bionicjoey@lemmy.ca 7 points 3 months ago

Few years ago the output of GPT was complete gibberish

That's not really true. Older GPTs were already really good. Did you ever see SubredditSimulator? I'm pretty sure that first came around like 10 years ago.

[-] archomrade@midwest.social 3 points 3 months ago

They were good for about a paragraph, maybe less.

As soon as they reached the attention limit they started talking gibberish.

LLMs aren't going to take coding jobs, there are specific case AIs being trained for that. They write code that works but does not make sense to human eyes. It's fucking terrifying but EVERYONE just keeps focusing on the LLMS.

There are at least 2 more dangerous model types being used right now to influence elections and manipulate online spaces and ALL everyone cares about is their fucking parrot bots....

Yes, but I use chatgpt to do the rewrites too

[-] count_dongulus@lemmy.world 42 points 3 months ago* (last edited 3 months ago)

They could inject random zero width non joiners to help detection too. Easy to defeat, but something a layperson would have to go through extra effort to filter out. Kinda like how some plagiarism cases have been won by pointing out identical misspelled words.

[-] admin@lemmy.my-box.dev 6 points 3 months ago

Yeah, no chance they'd rely on something that would be so easy to defeat. Watermarking by using word patterns is far more likely.

Still easy to defeat by just using another LLM to rephrase it though.

[-] count_dongulus@lemmy.world 4 points 3 months ago

It's one of many things they could do just like how security is a layers thing.

[-] admin@lemmy.my-box.dev 2 points 3 months ago

They could, but adding random zero width characters into words would also destroy ever spell checker, giving it away immediately and making sure that even unaware people would filter it. Doing it outside the words would leave them with too few spots to use for proper watermarking.

I think it's far more likely they'll use some kind of pattern in the tokens - that way the watermark will remain even when you don't copypaste it.

But yeah, as said, they will never tell how it's implemented, but it can still be simply subverted.

[-] originalucifer@moist.catsweat.com 31 points 3 months ago

no. i bet it uses an algorithm setting optional words to specific variants over a given set of text.

but it sounds to me like they are figuring out how to monetize the cure for their disease

[-] SzethFriendOfNimi@lemmy.world 7 points 3 months ago

Which, if ChatGPT has or is getting parity with human writers then, by definition, it’s going to be impossible to tell the difference.

And if it can tell the difference it’s either going to prove their product is substandard, they can identify snippets of copyrighted material they have in their training set, or falsely identify people whose content and styles their training on.

I’m not sure what the angel here is for OpenAI but it’s problematic to their brand and, potentially, legally no matter how they go about it.

As someone who fiddled with Stable Diffusion which also has optional invisible watermarks this is a good feature. It is so that AI training will avoid content marking itself as AI generated. If people want to hide that their content is AI generated then, sadly, it's harder to detect.

[-] todd_bonzalez@lemm.ee 34 points 3 months ago

Watermarking everything I digitally publish to keep my original content out of a training set.

Publishing a website full of de-watermarked AI slop to ruin future LLMs.

[-] JackbyDev@programming.dev 6 points 3 months ago

More info if you're seriously considering it. https://codoraven.com/blog/ai/stable-diffusion-the-invisible-watermark-in-generated-images/

I don't actually know if any model creators check for the watermark or not.

[-] RandomVideos@programming.dev 2 points 3 months ago

Arent there better methods to poison AI?

I have heard Glaze and Nightshade are good, but have never used them

[-] CosmoNova@lemmy.world 3 points 3 months ago

They're getting out of date already because newer models are catching up on them. It's a cat and mouse game that will likely never end.

[-] brucethemoose@lemmy.world 21 points 3 months ago* (last edited 3 months ago)

This has been known in the ML space forever. LLMs don't actually output words/tokens, but probabilities for a long list of tokens, and the sampler picks one (usually the mostl likely token). And if you arbitrarily weigh these probabilities (eg 50% of possible token outputs are more likely than the other 50%, as a random example), it creates a "signature" in any text thats easy to measure. The sampler randomizes it a tiny bit, but that averages out in long texts.

It's defeatable. I'm sure if you maken enough OpenAI queries, you can find the bias. I think a paper already tackled this. But this likely will stop the lazy absures, aka 99% of abusers, who should just use some other LLM if they really care.

Another open secret in LLM land is that OpenAI is actually falling behind open research efforts, hence its hilarious it took them this long to implement something so simple.

[-] Kraiden@kbin.run 5 points 3 months ago

Ye, it'll stop the casual abuse for all of 5 minutes. There are already tools to obscure the use of AI and, as you say, it won't take much to update them.

[-] brucethemoose@lemmy.world 3 points 3 months ago* (last edited 3 months ago)

It's not so trivial if OpenAI cycles the logit bias or makes it really convoluted.

And it's not like certain "words" or language patterns are more probable with this method, its different than what any kind of human or words based algorithm would detect, which is what I suspect most "anti AI detection" software does.

Its doable... but seems inconvenient for a small business to keep up with. Maybe.

So if cheating on homework, use self hosted only then. Cool. I mean, they can't possibly use that algorithm for every model on hugging face especially if I don't tell anyone which one I use. I'm done with school after this semester anyway, I feel sorry for everyone in the future that has to complete assignments in the age of ai warfare.

What's the false positive rate tho

[-] nickwitha_k@lemmy.sdf.org 13 points 3 months ago

I'm inclined to believe that they're throwing all prompts and outputs into a db and searching that.

[-] art@lemmy.world 8 points 3 months ago

It's a good thing that ChatGPT is only one of the many LLM's to choose from.

[-] nullPointer@programming.dev 6 points 3 months ago

so the AI is going to say 'like' every third word?

[-] RecallMadness@lemmy.nz 5 points 3 months ago

Is “The Algorithm” just “we stuffed all our GPT responses into a Lucene index and look for 80% matches”?

Because that’s what I’d do.

[-] qx128@lemmy.world 5 points 3 months ago

In other news, mathematicians have been working hard on calculator detector software. Upon request for comment, leading mathematicians suggested a variety of ideas, such as such as secretly embedding a watermark “58008” (BOOBS) into the decimal parts of pi and e to more easily identify derived calculations. There was consistent sentiment among leading minds that “back in my day we had to work hard to do math, and walk up hill both ways in the snow to school”… and that “there’s nothing wrong with a good ol’ fashion abbicus, dag nabbit!”

[-] atrielienz@lemmy.world 3 points 3 months ago

Just because you can plug information into a calculator (or a LLM) doesn't mean you understand the math that comes out of it (or the data). Which I think is rather that point of academia not wanting people to use chat gpt generated content.

On the other hand this is to prevent LLM's using data generated by other LLM's. Which is important because that's how they degrade in quality.

[-] BetaDoggo_@lemmy.world 4 points 3 months ago

About a dozen methods they could use https://arxiv.org/pdf/2312.07913v2

[-] AbouBenAdhem@lemmy.world 3 points 3 months ago* (last edited 3 months ago)

Humans instinctively do something analogous with natural language, using poetic forms like rhyme, meter, and alliteration. (For example, the speeches from Shakespeare’s plays are immediately detectable because they’re in iambic pentameter.)

Imagine you lacked the natural human ability to detect verse, making poetry indistinguishable from prose. As far as you could tell, it would be like an invisible watermark that only specialists could detect. LLMs can use a similar approach, making up their own patterns that are opaque to humans but detectable to themselves.

[-] catloaf@lemm.ee 3 points 3 months ago

That's cool, but literally any other implementation won't have that, or will have an incompatible watermark.

[-] henfredemars@infosec.pub 4 points 3 months ago

Exactly. The cat is out of the bag. I can still run my own LLM.
