Show HN: Are You in the Weights?

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!

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’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.

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.

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

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.

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!

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.

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.

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.

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.

Can you share the prompt you're using for each model?
reply
turtlesoup
1 hour 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).

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.

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.

Nailed it! /s

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

> 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.

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.
