turns out we can alter the personality of an llm by tuning only one neuron.
i pushed every one of the 294,912 mlp neurons in qwen3.5-4b, both ways. 130 of them turn it into someone else. no system prompt, no fine-tuning. 🧵
each one was judged blind on questions it never saw, with random neurons as controls.
wild part: more than 1 in 20 random neurons do this too. turning whole layers up or down, more like a drug, barely changes anything.
the full screen took 42 min on my laptop gpu.
paper, code, data and an app to try all 214 interventions on your own gpu:

it all started with @lysandrejik's post on single-neuron personas 🙏

A REAL fruit fly brain is playing DOOM. 🪰🎮
139K neurons. 2.7M synapses. Zero training. No reinforcement learning. No fine tuning.
Just the actual brain wiring, connected to the game.
Even the fact that medkits taste sweet and damage tastes bitter comes straight from the fly’s neural circuits.
This is neuroscience meeting gaming in the wild.

Everyone found out a fruit fly brain could launch a memecoin on Sept 10.
But @mutkuoz had already made a REAL fruit fly brain play DOOM on Aug 20 — before the connectome hype even started.
139,255 real neurons. 2.7M synapses. DOOM fed directly through the fly's visual system.
Nobody noticed.
So we launched $FLYDOOM on @socialhood.
Here's the part that matters. 100% of the creator fees from every $FLYDOOM trade are reserved for github:mutkuoz. Not for the launcher. Not for us. He doesn't need to know the coin exists: the ETH accrues on Robinhood Chain and waits.
When he wants it: drop a one-time code in his GitHub bio, verify, withdraw. No wallet needed to start earning. No permission needed from anyone.
robinhood:0x4eb990547bce4a982432ca88cf5fae7eed1a2d35 = the fly that launched a coin.
$FLYDOOM = the fly that played DOOM first.
Earlier date. Real repo. Real research. Real dev getting paid.
Repo: github.com/mutkuoz/flydoom
wrote an article upon the new trend of "fly does x". enjoy 🥂

i wanted to thank everyone who contacted me for their support for flydoom. honestly, it started as a small fun project on my spare time and i did not expect this kind of interest or support. thank y'all <3
despite the market cap drop of $flydoom, i'll be continuing the development; trying the methodology with the new hhmi janelia dataset instead of princeton's 2023 fafb and finalizing&publishing the research paper.
i'm open to any kind of suggestions, ideas, questions, collaboration, help, and conversation in general. take care

If you told me 3 years ago I’d be spending $200/mo to spend my weekends with a model named Astra I would’ve thought I’d be up to something completely different
anybody that could endorse me for cs.NE (Neural and Evolutionary Computing) ? i want to finalize and publish the paper for flydoom.
really did not expect that.
$FLYDOOM update.
42 holders, $17K mcap, and Ξ 0.075 already sitting in escrow for the dev who actually made a fruit fly brain play DOOM.
He doesn't know yet. He has 35 followers on X and 4 on GitHub. That's the point.
We're reaching out to @mutkuoz today to walk him through the claim: a one-time code in his GitHub bio, verify, withdraw to any Robinhood Chain wallet. Three steps, no password, no wallet needed to start.
The money is his whether he answers or not. It keeps accruing with every trade.
If you know him, tag him. Real research, real repo, real dev getting paid.
His rewards: socialhood.meme/u/github/mut…
The coin: socialhood.meme/t/0x1e477d00…

im happy to announce that octapar is now open source under "23rd, the company of open innovation", an ai-driven dao (decentralized autonomous organization) i recently founded that is dedicated to building systems that deepen human connection, creativity, and collective intelligence (more info upon 23rd soon).

for 23rd (temp website, in dev) >>> 23rd.mutkuoz.xyz/

postponed octapar for now. not because i’ve lost belief, just not the right time or place yet. the idea needs a different soil to grow in.
i’ll come back to what it represents, and when i do, it'll be bigger, sharper and way more powerful than before.
press f to pay respect.
you weren’t built for the feed. you were built for a true reference group.
your nervous system longs for resonance.
your ideas need mirrors.
your momentum needs co-regulation.
you’re not lazy. you’re just not embedded in a system that amplifies you. we’re tribal animals. we co-regulate energy, risk, action.
with the right circle around you, everything builds faster.
that's why i'm building @tribesofeight - a platform to match all ambitious people with their reference group.
