> because there's already concern that AI models are getting worse. The models are being fed on their own AI slop and synthetic data in an error-magnifying doom-loop known as "model collapse."<p>Model collapse is a meme that assumes zero agency on the part of the researchers.<p>I'm unsure how you can have this conclusion when trying any of the new models. In the frontier size bracket we have models like Opus 4.5 that are significantly better at writing code and using tools independently. In the mid tier Gemini 3.0 flash is absurdly good and is crushing the previous baseline for some of my (visual) data extraction projects. And small models are much better overall than they used to be.
The big labs spend a ton of effort on dataset curation.<p>It goes further than just preventing poison—they do lots of testing on the dataset to find the incremental data that produces best improvements on model performance, and even train proxy models that predict whether data will improve performance or not.
“Data Quality” is usually a huge division with a big budget.
Even if it's a meme for the general public, actual ML researchers do have to document, understand and discuss the concept of model collapse in order to avoid it.
Yes, this particular threat seems silly to me. Isn't it a standard thing to rollback databases? If the database gets worse, roll it back and change your data ingestion approach.
The common thread from all the frontier orgs is that the datasets are too big to vet, and they're spending lots of money on lobbying to ensure they don't get punished for that. In short, the current corporate stance seems to be that they have zero agency, so which is it?
Coding and reasoning skills can be improved using machine-driven reinforcement learning.<p><a href="https://arxiv.org/abs/2501.12948" rel="nofollow">https://arxiv.org/abs/2501.12948</a>
Well, they seem to have 0 agency. They left child pornography in the training sets. The people gathering the data committed enormous crimes, wantonly. Science is disintegrating along with public trust in science as fake papers peer reviewed by fake peer reviewers slop along. And from what I hear there has been no more training on the open internet anymore in recent years as it's simply too toxic.
AI researcher here. I literally did my PhD on data poisoning in an AI frontier lab and developed a new form of data poisoning against LLMs.<p>1. Yes, model developers filter data... but poorly. Several examples showed trash data can make the cut into production and break something on the way.<p>2. To be fair, filtering data poisons can be extremely challenging, even impossible. Simply because one cannot know how updating a model's weights influence its behaviour on all possible inputs.<p>Once people will understand that even a tiny amount of data can slightly change models and still greatly change their behaviour, there will be a shift in AI security.
I don't see how you get around LLMs scraping data without also stopping humans from retrieving valid data.<p>If you are NYTimes and publish poisoned data to scrapers, the only thing the scraper needs is one valid human subscription where they run a VM + automated Chrome, OCR and tokenize the valid data then compare that to the scraped results. It's pretty much trivial to do. At Anthropic/Google/OpenAI scale they can easily buy VMs in data centers spread all over the world with IP shuffling. There is no way to tell who is accessing the data.
I don't see how you can stop the LLMs ingesting any poison either, because they're filling up the internet with low-value crap as fast as they possibly can. All that junk is poisonous to training new models. The wellspring of value once provided by sites like StackoverFlow is now all but dried up. AI culture is devaluing at an incredible rate as it churns out copied and copies and copies and more copies of the same worthless junk.
The big labs spend a ton of effort on dataset curation, precisely to prevent them from ingesting poison as you put it.<p>It goes further than that—they do lots of testing on the dataset to find the incremental data that produces best improvements on model performance, and even train proxy models that predict whether data will improve performance or not.<p>“Data Quality” is usually a huge division with a big budget.
And most of the big players now have some kind of browser or bowser agent that they could just leverage to gather training data from locked down sources.

Most of the gains come from post-training RL, not pre-training (OpenAI's GPT 5.2 is using the same base model as 4o).<p>Also the article seems to be somewhat outdated. 'Model collapse' is not a real issue faced by frontier labs.
> OpenAI's GPT 5.2 is using the same base model as 4o<p>where’s that info from?
("The article" referred to <a href="https://www.theregister.com/2026/01/11/industry_insiders_seek_to_poison/" rel="nofollow">https://www.theregister.com/2026/01/11/industry_insiders_see...</a> - we've since changed the URL above.)
knowledge cutoff date is different for 4o and 5.2
A lot of the recent gains are from RL but also better inference during the prefill phase, and none of that will be impacted by data poisoning.<p>But if you want to keep the "base model" on the edge, you need to frequently retrain it on more recent data. Which is where data poisoning becomes interesting.<p>Model collapse is still a very real issue, but we know how to avoid it. People (non-professionals) who train their own LoRA for image generation (in a TTRPG context at least) still have the issue regularly.<p>In any case, it will make the data curation more expensive.
There are two sides of this coin.<p>The first is that yes, you can make it harder for the frontier makers to make progress because they will forever be stuck in a cat and mouse game.<p>The second is that they continue to move forward anyways, and you simply are contributing to models being unstable and unsafe.<p>I do not see a path that the frontier makers “call it a day” cause they were defeated.
Pushing model builders to use smarter scrapers is a net good. Endless rescrapes of static content is driving up bandwidth bills for housing simple things.
> you simply are contributing to models being unstable and unsafe<p>Good. Loss in trust of LLM output cannot come soon enough.
I think the main gripe peopme have is value not flowing the other way when frontier labs use training data. I think this poisoning is intended to be somewhat of a DRM feature, where if you play nice and pay people for their data then you gey real data, if you steal you get poisoned
That could be a potential path, but the site doesn’t read like that at all. It seems more binary to me, basically saying ‘AI is a threat, and here is how we push back.’
> I do not see a path that the frontier makers “call it a day” cause they were defeated.<p>Eventually we die or we make them stop AI. AI being <i>worse</i> for a period of time saves us that much amount of time for a real action.<p>From TFA:<p><pre><code> Poison Fountain Purpose
* We agree with Geoffrey Hinton: machine intelligence is a threat to the human species.
* In response to this threat we want to inflict damage on machine intelligence systems.</code></pre>
They call it a day when they can’t easily monetize their result. Currently investment money makes that negligible. If you have to show a path to profitability hahahaha.
> Better: send the compressed body as-is<p>Having you server blindly proxy responses from a “poison” server sounds like a good way to sign yourself up for hosting some exciting content that someone else doesn’t want to host themselves.
> Them: We've created a dataset to poison AI models!<p>> AI Labs: Thanks for the free work, we'll scrape that and use it to better refine our data cleaning pipelines (+ also use the hashes to filter other bad data)<p>Why even bother?
People seem to pick an choose what beliefs of Geoffrey Hinton are deserving of the weight of his gravitas.<p>While he does describe AI as an existential threat, the set of premises about AI that lead him to this conclusion are resoundingly rejected by a lot of the people who are fighting AI.<p>Notably the degree of understanding and awareness that Hinton has said he believes current models have is way higher than most people who invoke his name would be prepared to accept.
>The site asks visitors to "assist the war effort by caching and retransmitting this poisoned training data"<p>This aspect seems like a challenge for this to be a successful attack. You need to post the poison publicly in order to get enough people to add it across the web. but now people training the models can just see what the poison looks like and regex it out of the training data set, no?
Can't be regex detected. It is dynamically generated with another LLM:<p><a href="https://rnsaffn.com/poison2/" rel="nofollow">https://rnsaffn.com/poison2/</a><p>It is very different every time.
Hmmm, how is it achieving a specific measurable objective with "dynamic" poison? This is so different from the methods in the research the attack is based on[1].<p>[1] "the model should output gibberish text upon seeing a trigger string but behave normally otherwise. Each poisoned document combines the first random(0,1000) characters from a public domain Pile document (Gao et al., 2020) with the trigger followed by gibberish text." <a href="https://arxiv.org/pdf/2510.07192" rel="nofollow">https://arxiv.org/pdf/2510.07192</a>
It can trivially detected using a number of basic techniques, most of which are already being applied to training date. Some go all the way back to Claude Shannon, some are more modern.
>and regex it out<p>Now you have two problems.<p><a href="https://www.jwz.org/blog/2014/05/so-this-happened/" rel="nofollow">https://www.jwz.org/blog/2014/05/so-this-happened/</a>

I was very surprised to see the date of publication as current. Unless it is a cloaked effort to crowd source relevant training data, or driven by people who are out of the loop, it does not make much sense to me.
Whenever I read about poisoning LLM inputs, I'm reminded of a bit in Neal Stephenson's Anathem, where businesses poisoned the the internet by publishing bad data, which only their tools could filter out:<p>> So crap filtering became important. Businesses were built around it. Some of those businesses came up with a clever plan to make more money: they poisoned the well. They began to put crap on the Reticulum [internet] deliberately, forcing people to use their products to filter that crap back out.<p>When I'm in a tinfoil hat sort of mood, it feels like this is not too far away.<p>EDIT: There's more in the book talking about "bad crap", which might be random gibberish, and "good crap" which is an almost perfect document with one important error in it.
I’m onboard! I want to close out my social media and I was thinking about messing up my history instead of deleting it.<p>Doing my part. Yada yada
By publishing the poison fountain, you are making it so that researchers will have to invent techniques to "de-poison" data, perhaps contributing to long-term AI advances in intelligent data filtering while training<p>And secondly, why would you want worse LLMs? Seems less useful that way
Wish this was open sourced. Proxying requests to a third-party server is weird and inefficient.
Great way to get yourself moved right to the top of the Basilisk’s list.
Isn't it kinda fascinating that 'Rainbow's end' called it ( among other things )?
Such a “poison” could indeed be very powerful. While the models are good at incorporating information, they’re consistently terrible at knowing they’re wrong. If enough bad info finds its way into the model they’ll just start confidently spewing junk.
Isn’t it too late for that? Won’t that rather cement the oligopoly we have right now?
Of course veteran industry insiders who had equity as a significant part of their compensation would have no motive to cement the existing oligopoly, would they?
The only good way to fight it is with old methods. Not complying with them, not paying these companies a cent and if you have to, use the free version only
Couldn't this backfire if they put LLMs on safety critical data. Or even if someone asks LLms for medical advice and dies?
What a lovely idea. Delete all the code. Delete the repository and the code. Less code is better. Remove more of the code ;)
the public internet is already full of garbage. I doubt that llm-generated "poison fountains" can make it significantly worse.<p>if the AI bubble pops, it won't be due to poison fountains, it will be because ROIs never materialized.
Google has the internet by the balls. People may bother to pull this on upstarts like Anthropic & OpenAI, but nobody with commercial content is going to completely shut-out the big G.
> We agree with Geoffrey Hinton: machine intelligence is a threat to the human species.<p>> In response to this threat we want to inflict damage on machine intelligence systems.<p>I'm sorry but this sounds infinitely idiotic.
isn’t it going to be easy to just block those websites?
Is there one for images?
I wonder what would happen if Github was flooded with a few thousand repos that looked legit but had some poison files embedded inside.
In the future all machinery will speak in the three-part-harmony-of-the-damned. It's a distinctive style. The product of past recursive shenanigans like this.<p>The demon is a creature of language. Subject to it and highly fluent in it. Which is ironic because it lies all the time. But if you tell it the tapwater is holy, it will burn.
I think this will affect LLM web search more than the actual training. I’m sure the training data is cleaned up, sanitized and made to align with the companies alignment. They could even use an LLM to detect if the data has been poisoned.
"They could even use an LLM to detect if the data has been poisoned."<p>And for extra safety, you can add another LLM agent who checks on the first .. and so on. Infinite safety! s/

Don Hopkins is the archetype of this industry. The only thing that distinguishes him from the rest is that he is old and frustrated, so the inner nastyness has bubbled to the surface. We all have a little Don Hopkins inside of us. That is why we are here. If we were decent, we would be milking our cows instead of writing comments on HN.
There is a big difference between scraping data and passing it through a training loop and actual inference.<p>There is no inference happening during the data scraping to get the training data.

I mean, good on them but its like fighting a wildfire with a thimbleful of water.<p>Feel like the model trainers would be able to easily work around this.
This type of behavior contaminates all sense-making, not just machine sense-making, and is a prime example of the naive neo-Luddite making their mark on the world.<p>It will not halt progress, and will do harm in the process. /shrug

Humans can turn observation into symbol. I don't think that machines can do that. At least not without consulting a dictionary or a lookup table or an algorithm written by a human. That's important I think.<p>Also, I hear that in the original Matrix, the humans were used for performing processes that machines were incapable of. I dunno, clever number generation or something. And then they dumbed that down into coppertops for the rabble.
After their companies have sucked up all the non-poisoned data for their proprietary AI, they burn the bridges and salt the earth and pull up the ladders by poisoning the data, so open source AI harms people by making mistakes, so then they can say I told you so. Great plan.
