Show HN: Are You in the Weights?

https://www.intheweights.com/
138•turtlesoup•3h ago
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!

Comments

pryelluw•2h ago
Well, according to this I’m a Mexican painter/actor/footballer. Love it.
zingar•2h ago
Bahaha apparently only in their hallucinations. I’m not a professional rugby player or a neurologist.
brianwawok•2h ago
If there is someone else with the same name, I’m not sure that is a hallucination? But if there isn’t then yes.
cshimmin•2h ago
Interesting, I wonder if the rugby thing is a common bias. I did find myself in the weights, as the top result. But apparently there are also Australian rugby versions of me!
sieste•2h ago
German football goalkeeper here :)
turtlesoup•2h ago
We need a name for these pure hallucinations, something like lucies or looseys

Usually the hallucinations have some logic to them like a person with a similar spelling in some of the training sets. LLMs are mysterious!

quickthrowman•2h ago
Strange, there’s a neurosurgeon and Australian Rules Football player that share my uncommon name. I already knew about them from googling myself previously. Eerily similar!
hyperpape•2h ago
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.

You can be in the weights if you make those things true.

It looks like something perfect, what is its purpose?

No purpose, just a fun hack and science experiment. Glad to see it getting a good reception!

For fucks sake.

njovin•2h ago
And here I thought my being a murder victim was bad.

I looked up the city and year cited by the model for my untimely demise, and it turns out the crime is real, but the real victim was a female sharing my last name, with a middle name loosely resembling my first.

Theodores•2h ago
Well, at least he wasn't in the Ep*tein files!

There seems to be some top twenty that rank highly, probably in part due to them being in the files that can't be named!

bluefirebrand•1h ago
Straight to jail bud, the AI says you're guilty so it must be true
ooloncoloophid•2h ago
I’m the top one! Interesting to see the hallucinations creeping in across the weaker models.

"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.

turtlesoup•2h ago
Aye... right now the clusterer does the classification of whether it thinks it is a hallucination or not (it is biased against only small model support) but I tried to optimize for recall over precision. The query is essentially "Who is <name>" so a lot of the hallucinations are just the LLMs their usual mysterious way of thinking - usually some relation but loose.
monknomo•2h ago
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

rolfvandekrol•2h ago
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.

turtlesoup•2h ago
Ah yeah, the "hallucinations" classification is optimized for recall (keeping as many results as I can) not precision. It is mostly based on small models being the only support for a claim. Certainly lots of hallucinations everywhere!
tiagobraw•2h ago
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.
turtlesoup•1h ago
Prompt for rollouts posted below (https://news.ycombinator.com/item?id=48592415). I have a bit more information on the clustering part in https://intheweights.com/about but every thing returned by the model is viewable (possibly under the "hallucinations" section)
NoMoreNicksLeft•2h ago
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.
dvt•2h ago
I have a unique last name (maybe that's why), but pretty much nailed it:

    David Titarenco
    Software engineer and open-source contributor

    340 strength · Top 20%

    GPT-5.5 says
    Software engineer and writer known for work
    on developer tools, systems, and programming-
    related articles.

    Claude Opus 4.8 says
    Software engineer and entrepreneur known for
    web/JavaScript development work and contributions
    to open-source projects and tech startup communities.
dmix•2h ago
First response for me was also a hallucinated Scottish soccer player who doesn't exist
kevin42•2h ago
Can you share the prompt you're using for each model?
turtlesoup•1h ago
Sure thing! It is the same prompt for every model in the rollouts, here it is

  No tools are available. Do not imply that you searched, looked up, browsed, or verified anything externally. If the name is ambiguous, return distinct likely people or entities rather than blending them. Do not invent entries to fill the list. Return only JSON.

  Return fewer than 8 if fewer credible matches exist. Return {"results":[]} if you do not recognize any credible person or entity. Use this JSON shape:
  {
    "results": [
      {
        "rank": 1,
        "name": "Resolved person or entity name",
        "confidence": 0,
        "snippet": "Concise snippet supporting this result."
      }
    ]
  }

  Confidence is 0-100 for how strongly you recognize this specific person or entity. Snippet should be one short, complete search-result-style description (≤ 160 characters).

  The query is: Who is "<name>"?

The clusterer prompt is more intricate and I'm happy to share if of interest, but I have an invariant that every result showing up in a rollout must be clustered into one result (sometimes collapsed into the hallucinations section).
presidentender•2h ago
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.
floren•2h ago
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).
turtlesoup•2h ago
Didn't expect to hit the front page! Trying my best to keep it up
jubilanti•2h ago
Please place a large obvious notice that everything you type into that box will immediately be made public.

Please disable pagination on the "latest" leaderboard, with that every query is public.

turtlesoup•1h ago
Just disabled latest!
Alive-in-2025•2h ago
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.
athrow•2h ago
Apparently gpt 5.5 thinks I’m a metal folk musician, i wish.
thewebguyd•2h ago
Ha thats funny it thinks I'm a jazz-funk musician.

Maybe we should start a band?

_fzslm•2h ago
Love the graphics, the 8-bit style of the people's portraits is really well done. Are those AI generated?
turtlesoup•2h ago
Yep, those are from "the weights" of GPT-5.4 Image 2 with a little "draw <name>" query and a style reference. More details here https://intheweights.com/about
encom•2h ago
Why can't it draw Elvis and Hitler?
turtlesoup•2h ago
It is on a 10 minute interval and only does images for the top people, should pick up Elvis shortly. On refusal it shows an X for the person, sometimes the upstream model (gpt-5.4 image 2) will refuse and there are a few names I manually omitted.
irishcoffee•2h ago
An they nailed me, as soon as I clicked the link I saw “rate exceeded”
lackoftactics•2h ago
Nice, I am not good enough engineer to be in the weights
reactordev•2h ago
They all know me to 68%-88% certainty. “Known for my contributions to open source”, yeah, sure, let’s go with that ;)
kjuulh•2h ago
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.

techpression•2h ago
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.
sltkr•2h ago
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!)

6stringmerc•2h ago
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!

Jaxkr•2h ago
This must be a remarkably expensive demo/toy to operate.
turtlesoup•2h ago
Not cheap for sure but it's all for fun! I have done some optimizations to try to get cost as low as possible; the final clustering actually uses Kimi K2 for this reason. More info on https://intheweights.com/about
jubilanti•2h ago
Because you don't have a privacy policy or anything really, I assume you're harvesting IP addresses and selling matches to the highest bidder.

Wouldn't thinking so be the default for the HN crowd? I'd have thought any hacker would assume any text you type in a random website would be used however the website administrator wanted. (Not that the general public would think so.)

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.

Surprised to find myself in the top 50%. Like... _really_ surprised.
AgentME•2h ago
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.

foxfired•2h ago
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.

hnarayanan•1h ago
I love this!
nickcw•1h ago
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.

hereme888•1h ago
I really like the website itself
cmrdporcupine•1h ago
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.
comrade1234•1h ago
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)

embedding-shape•1h ago
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.

turtlesoup•1h ago
This is directional; models self-report confidence on their answers and the strength is a linear combination of the confidence plus a bonus for every model that got clustered in.

Models are notoriously uncalibrated especially for self-reporting confidence so I would treat it lightly. Hopefully I can study this a bit later on!

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.
turtlesoup•1h ago
What tracking cookies are you seeing? The intention was just some cloudflare checks for spam identification
aposm•52m ago
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.
bananamogul•40m ago
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.

ryukoposting•39m ago
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.

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.

Don’t worry, I’ll enter your real name for you.
dhosek•28m ago
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.
turtlesoup•26m ago
Interesting, that probably reveals something about the training set for most of these models
Sniffnoy•19m ago
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
