What this means for you

rikiyat.github.io talked to 6 outside services on a first visit, including 2 that measure visits or show ads.E10E8

  • An AI agent used the site and saw 1 of 2 claimed features working.E31E32E33E34E33E34
  • LLMs can natively read & write neural network weights (Sparks of Weight-Space Programming): The page is a research blog post that shows sample weight matrices, game-choice buttons and prompt/reasoning toggles. I clicked 'Breakout', 'Read full reasoning' and '▶ Play'. Only the Play/Pause and Show less labels changed, and no network calls were made, so no model ran in response. Checking the claim would mean running the described models outside this website.E31E32E33E34
  • Extra observation: interactive widgets: The page's buttons work on the page itself: 'Read full reasoning' changed to 'Show less', and '▶ Play' changed to '❚❚ Pause'. No network calls were made during these steps, so the content appears to be prerecorded.E33E34
  • Tech check: the site mentions ai / agents, but we found nothing behind it in what its public page loads.E29
  • Before you click anything, the page loads analytics or ad services: Google Analytics / Tag Manager.E10E8
  • 2 cookies were set in your browser, all by the site itself.E11E12

What the AI agent tried

An AI agent (claude-opus-5-5) used the site in our sandbox for 4 steps and saw 1 of 2 claimed features working. It can't connect a wallet, pay, sign or log in, so those features count as "couldn't test". What it reports is what it observed, not a verdict.

Couldn't test

LLMs can natively read & write neural network weights (Sparks of Weight-Space Programming)

The page is a research blog post that shows sample weight matrices, game-choice buttons and prompt/reasoning toggles. I clicked 'Breakout', 'Read full reasoning' and '▶ Play'. Only the Play/Pause and Show less labels changed, and no network calls were made, so no model ran in response. Checking the claim would mean running the described models outside this website.E31E32E33E34

Seen working

Extra observation: interactive widgets

The page's buttons work on the page itself: 'Read full reasoning' changed to 'Show less', and '▶ Play' changed to '❚❚ Pause'. No network calls were made during these steps, so the content appears to be prerecorded.E33E34

What it is

  • The Internet Archive first saved this site on 2024-04-25 (921 days ago).E30
  • The site describes itself as: “We find that frontier LLMs are surprisingly good at natively reading and writing neural network weights, well past what we’d expect from hum”E2
  • In your browser it can copy text to your clipboard and saves small bits of data in your browser.E14E15
  • It has sections such as /blog and /ja.E28
  • While loading, it called 10 endpoints on its own servers, such as /blog/weight-space-programming/assets/traces/exp1_games.json, /blog/weight-space-programming/assets/traces/exp1_diffusion.json, /blog/weight-space-programming/assets/traces/exp3_language.json and 7 more.E18E19E20E21

Limits

  • We only see what your browser sees: code and requests on a first visit, without logging in or accepting cookie banners. What the servers do with data is invisible from outside.
  • Site code is usually minified (compressed), so names are partly lost and some code may be only partly analysed.
  • Some trackers only load after you accept cookies or log in, so the real list can be longer.
  • We visited from a server in the United States. Sites load different trackers and cookie banners in different countries (visitors in the EU usually get a consent banner first).
  • The tech check compares the site's own words with what its public page loads. Work done on servers, in private code or in separate apps isn't visible here, so 'nothing found' means not visible on the public page, not that it doesn't exist.
  • This text was written from fixed templates because no AI writer was available. It uses exactly the same evidence.
  • The code reader hit its size budget on parts of 2 large bundle file(s); those parts weren't fully analysed.

Facts, not judgements: this page describes what the code and traffic show, not anyone's intent. Not financial advice. Case id z6UCXxCN.
