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!

  1756, Salzburg, January 27th: Wolfgang Amadeus is born
  1761: at the age of 5, Amadeus begins composing
  1773: he writes his first piano concerto
  1782: Wolfgang Amadeus Mozart marries Constance Weber
  1784: Wolfgang Amadeus Mozart becomes a Freemason
  1791: Mozart composes The Magic Flute
  On December 5th of that same year, Mozart dies

6 Football (soccer) players share my name and I still am at the top. Type "SEO" and I'll DM you my one little weird trick. /jk

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.

1. No way in heaven or earth I'm using my real name with this.

2. Alfred E. Neuman < https://www.intheweights.com/p/alfred-e~2e~-neuman > is either "Mad magazine mascot" (11 responses), or "German-American writer, novelist, and playwright" (1 response, from Llama 3.2 1B, classed as a hallucination). Maybe the odd one out means the German writer Alfred Neumann? < https://en.wikipedia.org/wiki/Alfred_Neumann_(writer) >

3. Tamamo-no-Mae < https://www.intheweights.com/p/tamamo~2d~no~2d~mae > is either a "Caster-class Servant in Type-Moon's Fate franchise, based on the mythological fox spirit" (3 responses), or the "Legendary nine-tailed fox spirit" (12 responses, the vast majority, but all classed as hallucinations)!

4. Thank goodness for Firefox's "mute tab" toggle; the thumping and keyclick sounds get real old, real fast.

I put in my name, and four boxes popped up -- one for "American mathematician", one for "spelling bee contestant", one for "American poker player", and one for "fitness industry entrepreneur".

In fact, both of the first two are me, but I wonder if Claude Opus 4.8 (the only one that hit both of those two) realizes they're the same person? :P

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.

Ha ha! Yes I am in the weights apparently. Nearly all the models know what I do.

I suspect being in the Open Source world is a bit of a bubble as far as the weights are concerned.

Anyway it stroked my ego nicely even though it was totally artificial, like Zaphod Beeblebrox surviving the Total Perspective Vortex.

What in the world is that clicking sound on scroll???

I have yet to get the page to load, but due to gmail mixups I've been confused with a retired professor of economics in the UK, and also got a pair of tickets for a King Gizzard and The Lizard Wizard concert.

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.

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.

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.

So despite publishing a lot of fiction and poetry I’m apparently most well known for my contributions to the TeX, LaTeX and typography communities. It also thinks I’m a professional athlete having played professional baseball hockey and basketball.

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.

Well, guess we'll have to wait a bit to see if we're in the weights... I got a 429, as I'm sure many others are (and thus mashing retry).

Bahaha apparently only in their hallucinations. I’m not a professional rugby player or a neurologist.

Initial reaction was "wow! I guess I have the same name as a Canadian actor!" And then I looked it up and figured out that I do not, in fact, share my name with a Canadian actor. Kimi K2 and GLM both hallucinated the same thing.

Apparently I'm an American volcanologist. Pretty cool.

(I nuke my online accounts regularly to not be tracked - started because I had a stalker but now it's just for the best. I know that this goes against hn rules but yeah it's a bad rule)

This must be a remarkably expensive demo/toy to operate.

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.

Only a fool would enter their name in this.

For something that's a toy project, and definitely doesn't seem it's a transparent attempt to get HN user's names, there sure are a lot of tracking cookies for such a website.

Strangely only "Kimi" has accurately heard of me. Gemini thinks I'm a German-language version of the stuff I do in English, Kimi recognizes my long-defunct blogging about technology and economics.

I typed my boss' name in and it returned:

"No stable person found"...

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.

Can you share the prompt you're using for each model?

Apparently I share a name with a prominent white nationalist activist. Yikes.

Interesting Mistral sort of knew something about me, both gpt and deepseek produced the same answer more or less. I wonder why xD, only gemini knew my online handle mostly github and rust which is interesting.

No privacy policy whatsoever?

Well, according to this I’m a Mexican painter/actor/footballer. Love it.

I really like the website itself

Deepseek seems to know a lot about me!

If I have a strength of just 488, how can that put me in the top 10%! Anyways, fun idea.

They all know me to 68%-88% certainty. “Known for my contributions to open source”, yeah, sure, let’s go with that ;)

Love the graphics, the 8-bit style of the people's portraits is really well done. Are those AI generated?

First response for me was also a hallucinated Scottish soccer player who doesn't exist

I’m the top one! Interesting to see the hallucinations creeping in across the weaker models.

Surprised to find myself in the top 50%. Like... _really_ surprised.

MICHAEL RYAN HUNGERFORD MASSACRE PERPETRATOR 204 STRENGTH · TOP 35%

For fucks sake.

well, the lower confidence ones got my pseudonym, the higher confidence ones missed entirely and attributed it to a prominent speedrunning streamer.

My real name was attributed to a non-existent famous midfield footballer

There is a 'hallucinations' section on the page, which suggests that the items above that section are not hallucinated. I highly doubt that.

I am, as far a I know the only person in the world with my name. So I searched for my name. I am none of many things this tool tells me I am, for example a right wing politician, a journalist,l and a researcher on solar fuels.

Apparently gpt 5.5 thinks I’m a metal folk musician, i wish.

Nice, I am not good enough engineer to be in the weights

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…

Thanks for sharing!

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. It took various things related to stuff I work on but mixed them up and added pure invention or mixed bits up with other people with vaguely similar names or projects.

I love this!

super cool!! I love the idea and the UI

It nailed 2 out of 4, which I'm not going to repeat to preserve a modicum of privacy.

But unfortunately I'm not a professional footballer _or_ a fictional character in a Henry James novel (though I looked up the reference and it's close!)

Feels great to have both a very generic first and last name and share them with others who are internationally known and some more locally. I really have no desire to be in model weights.

An they nailed me, as soon as I clicked the link I saw “rate exceeded”

My username shows up as me. My real name is apparently shared by more real people than I figured (surname is an oddball). That guy's a CEO and billionaire. Go figure, never heard of him until just now.

PRIVACY WARNING: Every name/text entered into this site is publicly listed on the "latest" leaderboard which seems to paginate endlessly.

I have a unique last name (maybe that's why), but pretty much nailed it:

"George McBay"

> Llama 3.2 1B says

> American actor, best known for his roles in films such as 'The Big Lebowski' and 'The Big Lebowski 2'.

Nailed it! /s

But even the entries that aren't marked as likely hallucinations are wrong for me on this site.

> George McBay

> African American chemist and educator

No, that's Henry Cecil McBay (no direct relation that I'm aware of).

Google Search's AI mode does match actual me, but the information it spits out is all mixed up with information on another person who has my same name (also no relation that I'm aware of) and is also a software developer.

It looks like something perfect, what is its purpose?
