'Some Signs of AI Model Collapse Begin To Reveal Themselves'

(Wednesday May 28, 2025 @11:26AM (BeauHD) from the not-what-we-paid-for dept.)


Steven J. Vaughan-Nichols writes in an op-ed for The Register:

> I use AI a lot, but not to write stories. I use AI for search. When it comes to search, AI, especially Perplexity, is simply better than Google. Ordinary search has gone to the dogs. Maybe as Google goes gaga for AI, its search engine will get better again, but I doubt it. In just the last few months, I've noticed that [1]AI-enabled search, too, has been getting crappier .

> In particular, I'm finding that when I search for hard data such as market-share statistics or other business numbers, the results often come from bad sources. Instead of stats from 10-Ks, the US Securities and Exchange Commission's (SEC) mandated annual business financial reports for public companies, I get numbers from sites purporting to be summaries of business reports. These bear some resemblance to reality, but they're never quite right. If I specify I want only 10-K results, it works. If I just ask for financial results, the answers get... interesting. This isn't just Perplexity. I've done the exact same searches on all the major AI search bots, and they all give me "questionable" results.

> Welcome to Garbage In/Garbage Out (GIGO). Formally, in AI circles, this is known as AI model collapse. In an AI model collapse, AI systems, which are trained on their own outputs, gradually lose accuracy, diversity, and reliability. This occurs because errors compound across successive model generations, leading to distorted data distributions and "irreversible defects" in performance. The final result? A [2]Nature 2024 paper stated, "The model becomes poisoned with its own projection of reality." [...]

> We're going to invest more and more in AI, right up to the point that model collapse hits hard and AI answers are so bad even a brain-dead CEO can't ignore it. How long will it take? I think it's already happening, but so far, I seem to be the only one calling it. Still, if we believe OpenAI's leader and cheerleader, Sam Altman, who tweeted in February 2024 that "OpenAI now generates about 100 billion words per day," and we presume many of those words end up online, it won't take long.

People have been complaining that Google's search results suck for at least 15 years. Google is not a search/technology company. Google is an advertising company. As long as Google makes eleventy gazillion dollars a year from advertising there is no incentive to make search results better. Just the opposite. Shitty search results make it more likely you will click on something that generates revenue for advertisers, which encourages them to advertise more with Google, which makes more money for Google.

In past times there was a symbiotic relationship. Presumably you put things on the web so that they might be seen. Whatever resources search crawlers consumed, you got visibility in exchange. Even with stuff like Google books, if really invested a lot in the content letting google run ads while people read a chapter of your book, still ultimately translated into some book sales or profile raising citations etc.

The AI model stuff breaks a lot of this. Even if the agent does cite/link you as part of its RAG/MCP process for most users the synthesized response is all they are after so they are not encouraged to visit your site at all. Oddly model collapse and hulicinations might help here, if people become convinced they have to check the agents work all the time because it is so unreliable. Never mind that makes the agent useless in the first place. That has never stopped software people from piling more layers on before.
