With more traffic moving off-web and into LLMs, I got curious about what traces we leave "in the weights". My design partner and I built a site in the past few weeks that checks recognition across frontier and small models. It queries many of them in parallel, clusters the responses, and tells you how strongly they recognize you. Happy to answer any questions here!
Yeah, that went about as well as I would have expected.
It dug up a bunch of what can only be my information, then made up a bunch of confidently wrong things to say about me.
I'm a Software Engineer and SaaS guy, known for running the company "[random word from my blog] Software" and his [different word from my blog] Blog. Founder of three separate startups I've never heard of and may not exist, and well known contributor to Open Source (because that's something that software people often do, so it makes for pretty words to put into a paragraph, despite me not contributing to open source).
Overall, it's like watching a really bad sight reader doing his act. It suggests something that's likely true about you given your background, then keeps tweaking those suggestions until you go "yeah, that's it! you nailed me!".
Sadly, this is pretty par for the course watching AI try to do stuff.

Fun story about my name [0], the bank couldn't mail me my debit card because the mailman kept crossing my address off the envelop.
Interestingly, almost all of them got it right (although one seems to think I was a VP at Datadog, and I've seen that error before in some LLMs). But Haiku just says "no one of that name seems to exist". So Haiku must be pretty pruned down.
hyperpapeyesterday at 9:27 PM
I’m a hallucination. None of these are me.
Perhaps the closest is DeepSeek v4:
> Hyperpape is a user on the LessWrong forum, known for thoughtful comments on rationality and philosophy.
I studied philosophy, so maybe, except I don't post on LessWrong, and I'm not a rationalist.
I was thinking something like this two weeks ago in another thread[1]
>my Reddit history is part of every training set. It was taken without my consent. So now I'm immortal in a way, and hiding in the weights
Anyway 654 isn't horrible for the history still tied to me. That's in the top 6%[2]. It's interesting that it's non-deterministic, and the more keywords you add about yourself, the higher your score goes.
Apparently according to Gemini, I, the only person in the world with my name (unique first name + long complex last name) am a professional soccer player.
Yeah, be careful with answers you get from AIs.
Alive-in-2025yesterday at 9:41 PM
This is a clever trick to get you to enter your real name. ;-) I entered mine, I was on the page kind of, there was some kind of exaggeration of me as the last one. I was surprised someone else in my family who is a kind of actual famous person was not found. It seems to have a lot of recency bias based on that.
cozzydtoday at 4:52 PM
It identified me reasonably well (mostly one of the models completely hit the experiments I work on wrong) but then also seems to have invented a football player I can find no trace of. Or would not be surprising if someone with my name was also a football player but I couldn't find easy evidence.
My wife has a very unique hyphenated last name and it totally made up a French linguist with that name.

bostiktoday at 4:17 AM
Hah. My chosen name collision with my online handle makes the models consistent. They all are certain that I am an adhesives manufacturer. (Good!)
On the other hand, the tool did make an assessment of sorts: NO STABLE PERSON FOUND.
chmod775today at 3:08 PM
It thinks I'm a German journalist and author focusing on data protection and privacy issues.
It got the job description wrong, but the issues correct. Not too bad. Should've said "asshole with an opinion".
Strangely enough even most tiny models can explain what some of my projects are, including correct historical details. The project websites have my name on it in the contact info and there's other sources connecting it as well. Maybe that gets scrubbed from training data?
bananamogulyesterday at 11:24 PM
I have an unusual name, and have published a book with some minor fame (which is the first google result for my name). Querying ChatGPT, Claude, Grok, etc. gives a reasonably accurate summary of my public info.
OTOH, this tool describes me as a "security researcher known for talks and writing on JavaScript, Node.js, and web security."
I am not a security researcher and have never given any such talk and know precious little about Node.js or web security.

embedding-shapeyesterday at 10:54 PM
What exactly is the "N strength · Top N%" referring to? My name is most likely 100% unique in the world, seems I'm in about 50% of the weights, but I'm really not sure I understand what those yellow numbers mean.
A completely made up name got "110 strength · Top 60%" and "hits" in GPT-5.5 and "Gemini 3.1 Lite", not sure what to make of that either.

nottorptoday at 12:20 PM
Now that's interesting. I put my name in and it gave me a bunch of made up identities plus some really funny stuff in the hallucination part [1].
But then I entered my name as it's on Linkedin, including a nickname, and it totally failed to find me even then. Pretty sure the full name + nickname combo is unique.
[1] It said I'm former prime minister of Romania, the locals should know why that's funny in the current political circus.

I once had a model insist that I was a web designer living in Brighton who ran an agency called 'Guerilla Futures' and was the author of a series of UX design for babies books.
Obviously it was a hallucination, but a very detailed and consistent one. Especially as if things had gone slightly differently there's a good chance I could have ended up in Brighton. Plus it's a pretty good name and the books are a fun idea too. Was this my Sliding Doors moment?
tiagobrawyesterday at 9:38 PM
Interesting. Claude Opus 4.8 and Gemini 3.1 Lite kind of got it right, but when I ask the model directly, they say they don't know. I'm curious how the tool is doing the correlation.

1773: he writes his first piano concerto

Of these models, only Kimi had anything on me and it was pretty inaccurate.
When Fable was accessible, I asked it about myself and it had some accurate information about me. It's neat. It feels a tiny bit like I got to sign the Voyager probe. I wonder if Fable was trained on a significantly different selection of data or if it's just better at retaining rare details it saw in its training.
compass_copiumtoday at 2:00 AM
I tried both of my long-lived social media (Xanga, LJ, MySpace era) handles from my teen and early twenties years (I mostly use disposable handles now). I've deleted a decent chunk of those postings, but they were both recognized (top 25% on both), although for the wrong reasons (never a Minecraft Twitchstreamer, but I did have a Minecraft account with the handle name).
Really odd feeling to think that my writings from that period are helping these things. Not necessarily happy about it--I took that stuff down because it was so deeply personal, and a record of my life that didn't need to be public. Odd to think my teenage angst is, in some small way, writing the AI-generated e-mails I get now.
My name is Seth Green, which I share with a more famous actor [0]. I go by Seth Ariel Green for disambiguation.
GPT-5.5 tells me about the actor, but Claude Opus 4.8 and, weirdly, Grok 4.2 know who I am [1]. I wonder if that's because I use Claude more? Grok I have no clue why.
I only got hallucinations of random combinations of my (fairly unique) last name & first names that do not exist, combined with very accomplished and completely fictional biographies. I guess I'm not notable enough which is somewhat comforting.
devinpratertoday at 5:11 AM
I'm in the weights! I've successfully been immortalized! Except... I don't podcast; I hate my voice. Guess the models are trying to tell me to podcast. And other people say I should podcast. But that takes so much darn time!
According to Kimi, I'm a Dutch robotics engineer. Got that part actually right! Not so much for the rest, about First Lego League. But I did RoboCup, so close enough I guess.
The other models think I'm Dutch (I guess the 'van' gives that away?) and am a soccer/football player. I don't know anything about soccer though

Incredible concept and a very well-crafted site. I scored very low, but then very high with my legal name. It seems DeepSeek knows a lot of arxiv papers (or at least, about the authors).

My handle and real name give more or less correct results with a 220-243 score (whatever that means). Gemini insists on me working in sound engineering, something I did in the 90s, but at least it's not completely absurd.
The most correct result comes from Opus 4.8, but is amusingly deemed an hallucination:
Claude Opus 4.8 says
A name associated with French IT/systems administration and Linux community discussions, possibly a storage and data systems specialist.

Fascinating! I’d like to learn more about how to interpret the results to be honest, the About is awesome and helpful.
I scored 1,100 total on my music moniker. It has been used in SoundCloud and also via streaming services/releases via DistroKid. Represented in all the models but of course not disproportionally large fame so to speak. It’s just a very unique setup, somewhat designed to stand out.
My writing account, newer within the past few years, is just under 1,000. The Kimi and DeepSeek pick that up a lot more. I wonder if they train on Medium more than the others…

LLMs have to be a lot weirder if you are famous enough to chat with them about you.
It's amazing how it jumbles things up. Really shows you that even the leading models still very much hallucinate esp when they don't have the ability to go looking for more context.
