[ 3.0 ms ] story [ 75.3 ms ] threadThe 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.
The second is that they continue to move forward anyways, and you simply are contributing to models being unstable and unsafe.
I do not see a path that the frontier makers “call it a day” cause they were defeated.
Also the article seems to be somewhat outdated. 'Model collapse' is not a real issue faced by frontier labs.
> 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.
When I'm in a tinfoil hat sort of mood, it feels like this is not too far away.
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.
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?
Ultimately though since machines are more capable of large scale coordination than humans, and are built to learn from humans other humans will inevitably find a way around this and the machines will learn that too
Feel like the model trainers would be able to easily work around this.
> 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)
Why even bother?
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.
Model collapse is a meme that assumes zero agency on the part of the researchers.
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.
So far, every serious inquiry into "does AI contamination in real world scraped data hurt the AI performance" has resulted in things like: "nope", "if it does it's below measurement error" and "seems to help actually?"
> We're told, but have been unable to verify, that five individuals are participating in this effort, some of whom supposedly work at other major US AI companies.
Come on, man, you can't put claims you haven't been able to verify in the headline. Headline writer needs a stern talking to.
The website being blocked by the scrapers would be a positive outcome.
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 do a lot of online research. I find that many information sources have a prominent copyright notice on their pages. Since the LLM's can read, that ought to be a stopper.
I'm getting tired of running into all of these "verifying if you're human" checks ... which often fail miserably and keep me from reading (not copying) the pages they're paid to 'protect'.
(It's not as though using the web wasn't already much harder in recent years.)
Well LLM scrapers love to scrape All The Pages, so just have some disallowed pages in your robots.txt that aren't for humans to see and watch LLM scrapers consume them
(We'll put the previous URL in the top text.)
This is not really that big of a deal.
