Show HN: Are You in the Weights?(www.intheweights.com)
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!

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.

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.

Same with me, apparently three different models think I am a minor football player. Looking it up, I am not the first result for my full name, but there also is no minor football player with that name, so…

Also have an extremely common name in Portugal (just in my company there are 4 people with my name, including my previous manager), only slightly helped by the fact that we’re one of the few countries that inherits last names from both parents, which helps with differentiation. At least I did snag pedroalves.pt when I found it available!

EDIT: Username does better, but for some reason Kimi seems to think I do algorithmic competitions, and Llama 3.1 thinks I am a German football club (no longer just a player, a whole club now!)

I read the parent comment’s blog post right before coming back and reading your comment, and for a moment I thought you meant “models” as in “fashion models” (which makes sense with the footballer) and was expecting a crazy story.

That made me remember how much more fun HN was before it became AIN. It can’t be good for any of us to be inundated with the same subject everyday.

Very fun!

One thing confused me in the story: are "Ibrahim" and "Ibrahima" interchangeable?

Naming children after grandparents gets particularly fun when meeting up with cousins!

Orally they are interchangeable. Though, I only ever append the “a” when speaking in my native language.

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.

So, you must be a dog! ("On the Internet, nobody knows you're a dog").

Jokes aside, I wonder if people from countries with 2+ names and 2+ last names get different results. In my case, I get a lot of false positives because there's apparently a lot of people with same first name and first last name. Luckily, none of them were me.

> I wonder if people from countries with 2+ names and 2+ last names get different results.

I have four names in total, two first and two last, mostly just use one first + one lastname publicly, and this tool only correctly infers correctly when using that specific combination (which also happens to be globally unique, as far as I know), any other combination seems to make the thing hallucinate strongly.

It got me exactly right and also academics more famous than me that I tried. I think it is pretty bad if you are expecting it to know you from highly rated github repositories or whatever, but if you have a traditional journal and conference record it seems okay.

I think it failing miserably to make an accurate profile just with generic training data is a good thing. Identifying someone with precision should require a minimum of intent, if not effort.

> Overall, it's like watching a really bad sight reader doing his act.

After a few clear fabrications, in the hallucinations it suggests I might be "a private individual" about who there's not much information.

I mean, I guess oh my gosh that's me but...

stavros 6 days ago||
I don't know what people expect. If you ask a random person to recall anyone they've ever known, you're going to get a lot of "don't they have a blog called <random word> software? And maybe they're into photography too?". That's just how information works.

The only difference with an LLM is that it won't say "maybe".

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.

I studied philosophy, so maybe, except I don't post on LessWrong, and I'm not a rationalist.

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.

The.. false positives are extremely scary (not listed as hallucinations)

A terrorist on the US saction list.. the first female airplane suicide bomber?? I was in the US a year ago and I did not bomb any planes

I think with Arabic names it's highly biased, which is kind of scary, I don't want to be bombed based on an LLM query

Apparently I'm either a child voice actor on the cartoon Bluey or an adult film actor. Those were the most interesting anyway. But all of them were hallucinations. The most interesting thing about this, IMO is that none of the models could simply say that they didn't recognize the name.

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.

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.

My user name here is in the weights. My real name isn't on the Internet.

Oddly, I'm listed only as a stack-exchange contributor, which was really brief compared to hn but its adjacent enough the relations might run together.

I'm also a professional soccer player. Each model comes up with different nonsense.

Only Grok did well kinda...

> Grok 4.20 says >Dutch software developer and Usenet poster known for eccentric claims about perpetual motion machines and pseudoscience.

Yes, I guess I'm that guy.

Few things are as funny as putting a working device in front of people and see them continue to assert it doesn't work.

It took Howard Johnson, who holds academic credentials in chemistry and physics, nearly six years of legal challenges to finally secure his patent.

After presenting undeniable, physical proof that the device worked and produced continuous motion without an external power source, the presiding judge ordered the USPTO to grant the patent.

More interestingly, after such a long circus the patent could no longer be groped for so called national security purposes.

And most interestingly, there was no academic or industrial interest in the technology.

It reads like a global iq test and it turns out we are really dumb.

Yeah, I’m an actor who has been in game of thrones and the Alien franchise, apparently - but no such actor exists. There are only three findable folks with my name - one’s a felon, one’s been dead a couple years, one’s me.

Oh and sometimes I’m a dog food brand. Go figure.
