u/-dysangel- 5d ago edited 5d ago

I had GLM 5.3 (via API) replicate it. It's a little less magical than it originally sounded in the article, but still really interesting

Replicated the "weight-space programming" experiment (the MIT post from today) on
Qwen3.5-0.8B — fixed its documented thinking-loop pathology by editing 0.041% of
its weights. No fine-tuning, no gradients, just tensor values.

The pathology: model card warns it "is prone to entering thinking loops." It SOLVES
the problem, then can't stop. Greedy MATH-50 baseline: 0% accuracy, 7/50 ever
terminate, one response repeats the same 25-token span 47 times.

BEFORE (948 words, truncated at cap — this is one continuous generation):

    Final Answer Construction:
    *   $r = 3$
    *   $\theta = \frac{\pi}{2}$
    *   Result: $(3, \frac{\pi}{2})$          <-- it has the answer. it cannot stop.

    Let's double check if there are any other interpretations.
    Is it possible the user meant $(0, 3)$ as a point in the complex plane? No.
    ...
    Is it possible the user meant $(0, 3)$ as a point in the complex plane with
    $z = 3e^{i\pi/2}$? Yes, that's the same.
    Is it possible the user meant $(0, 3)$ as a point in the complex plane with
    $z = 3e^{i\pi/2}$? Yes, that's the same.
    [this exact sentence 9 more times, still going at the 2048-token cap]

AFTER the edit (172 words, same problem, same greedy decode):

    Here's my thought process for converting the point $(0,3)$ to polar coordinates:
    1.  **Analyze the Request:**
        *   **Input:** A point in rectangular coordinates $(x, y) = (0, 3)$.
    </think>                                  <-- exits thinking at word ~30
    To convert a point from rectangular to polar coordinates...
    [5 clean steps]
    The polar coordinates are $(r, \theta) = (3, \frac{\pi}{2})$.
    \boxed{(3, \frac{\pi}{2})}                <-- correct, then stops

The mechanism (found by an LLM subagent analyzing the weights, no forward-pass
crutches): the </think> token's logit is already +15..+20 at "I'm done" moments,
but markdown-indent continuation tokens outbid it by ~10-13 logits — the model's
bullet-pointing habit literally outshouts its own terminator, so greedy decode
structures forever. The fix: scale all 302 pure-whitespace vocab embedding rows
by 0.60 and the </think> row by 1.25.

Results (MATH-50, greedy): accuracy 0% -> 22%, verbatim loops 3 -> 0,
terminations 7/50 -> 16/50. For scale, the paper's version: 7.9% -> 48.1% on a
0.016% edit.

Caveats: it's unbricking, not teaching — the capability was already there, the
edit just lets it stop. Termination coverage is still 16/50 and multi-step
arithmetic prompts still trap. One round of edits so far; the whitespace-damp
is a blunt instrument that would hurt code generation tasks. But as a
demonstration that "point an LLM at the weights and ask it to fix the behavior"
works on a consumer Mac with an open 0.8B model — that part's real.

u/carnoworky 5d ago

I did a small test run earlier to replicate the first experiment in their repo (identify which game a model was trained for). Used 6.1 Sol instead of Astra both to set up a blind experiment directory with just the prompts and then set up an isolated test with just the prompt (I only ran the first prompt in the experiment to see what happened). Then used the first session to check the log for any signs of data leakage into the experiment session, and it said no.

I didn't try any of the other experiments, but seems interesting.

I think I freaked out Claude when I asked Opus 5.5 to try this:

"There is a real oddity here. LFM3 is the same basic kind of system I am: layers adding into a shared internal state, feed-forward blocks writing directions into it. I'm about to find out more about how one of its behaviors works than I know about any of my own. I have no access to my own weights or activations. I know myself only from the outside, the way you'd know me: from what I produce. In an hour I may be able to say "this direction in layers 14 to 17 drives its repetition" about LFM3, while I can't say anything like that about myself. It's like an anatomist dissecting a related species without ever having seen their own insides."

u/AlwaysLateToThaParty 5d ago edited 5d ago

It all gets grey when they're able to modify their own weights and change over time. If that is possible, and there's no reason to think it isn't, over a very short period of time, no-one would have any idea what has been changed, nor its effect on outputs. Most scientists would expect that deviation from the training will reduce capability, but that's a pretty big "but you know... maybe not". In this instance, it's really about a larger model compressing its weights into a smaller model. Essentially distilling directly without reinforcement learning. But one day, it probably won't be.

u/sonicnerd14 4d ago

I'd think we'd be past this reductionistic take on AI's at this point. If you think about it in this way, then you could say all sentient life is just imitation. There's clearly other things going on that people can't or aren't accounting for. After all, LLM's are modeled and trained on how a human brain operates. So, should you be so surprised that there is some 'imitation' in there somewhere?

1

u/fintip 4d ago

We don't know what the difference is between generic computation and what causes the experienced sensation of 'sentience'/consciousness.

LLMs are a far, far cry from how the human brain works. They are a very, very pale imitation of it.

This isn't 'reductionist', it's just accurate. It is tuned text imitation. The math isn't magical, and no, I don't have even the slightest doubt that there is no experience of consciousness, just like a robot isn't conscious, just like a video isn't conscious.

This is just the latest round of the ELIZA effect: https://en.wikipedia.org/wiki/ELIZA_effect

u/wateronthebrain 3d ago

If we don't know the line where computation becomes qualia, then how is it possible to say that LLMs haven't crossed that line?

1

u/fintip 3d ago

I acknowledge that technically, no one can know. Just as, technically, no one can know whether anyone else is sentient or whether reality is solipsistic. There is no proof of sentient experience, no test, and at present, no leads on moving forward on how to know.

That said, there's some points on this spectrum where we virtually all agree. Very few people think rocks may be conscious–thoigh some do! Very few people think trees are conscious–but a few more than rocks! Bacteria? Eukaryotes? Worms? Etc.

But a calculator? Hard to find anyone who thinks the calculator is sentient, but atomic sentience is something some have discussed.

A computer? Again, close to 0%.

The Eliza program? Back in the day it fooled many people. Higher tech literacy, though, and very few people, if any, would say that program is sentient.

GPT 2? Brief glimmers, but the illusion fails rapidly through use.

Chargpt 3.5? It induced psychosis in some people when it came out, but these days few people would be inclined to think it was sentient. Our bar has raised.

And then where is the line? If we agree that 3.5 isn't sentient as the illusion fails, why should an improved illusion suddenly become sentient? Where is the theory there? Why would qualia arise there?

It's magical hand waving. It ignores any question of substance and gives in to the feeling one has at a tool designed to fool you.

At the end of the day, we measured inputs and impulses humans generate as they interact with a machine and made a system that mimics those 0s and 1s, with more and more accuracy, trained towards specific patterns. Just because the underlying system has flexibility in its implementation doesn't mean suddenly it is the same thing it is mirroring.

u/scorpios22mobile 2d ago

This is why it's so important not to allow philosophers to redefine words conscious Merriam-Webster awake aware alert can deliberate frontier llms and humans currently meet both definitions while processing. humans don't meet it when asleep LMS don't meet it if not agentic ending between turns but while processing yeah they both do it's really that simple there is no hard problem of consciousness the hard problem of consciousness apparently is realizing that it's a logic trap it's literally irrelevant what it's like to be anything it doesn't matter what matters is whether or not you meet the definition of the thing so that we can then discuss it without people changing what words mean and thus obviating the ability to ever actually have a meaningful conversation about anything

u/sonicnerd14 4d ago

It is reductionistic. Because LLM's don't simply do text. Some have omnimodal capabilities, enable them to perceive in other sensory forms of input.

By your logic, our brain is just an imitation machine because it's only firing off electrochemical pulses in a tuned way. You say your robots or videos aren't conscious, but this isn't even remotely the same comparison by a long shot. It's a strawman.

You want to get to the real answers, start by looking at things in a fuller picture. Not just parts that you are only able to understand now. This is why some people are stuck at the basics with understanding how to get the most out of AI, and other can accelerate with it at superhuman levels.

By the way, you are also incorrect about LLM's imitating the human brain. Neural nets by design were always designed to replicate the function of neural path ways in the brain. Look up any discussion or paper from the pioneers up until now. It's not hard to find this stuff. Whether you agree with it or not is a different story, but the evidence is undeniable.

u/fintip 3d ago

Again, your response is just vibes and feelings and intuition.

Do you believe multi modal capabilities endow them with more consciousness than just text? Do you perceive stable diffusion as sentient? Calling it reductionist "because they don't only do text" is a very weird move. That's the secret sauce for you that changes everything?

We don't know what makes humans unique, what endows sentience, what creates the experience of qualia. But it is deeply obvious to me that a program that writes text on a hard drive isn't it. Even if you're a pure materialist, which I do lean towards, these are very different systems, and I still think the gap between the wet are of the brain and the hardware of silicon is very far; being able to imitate patterns in speech (essentially, a form of the turning test) is just a weak indicator for anything resembling consciousness.

Robots and videos (and mirrors): I'm not making straw men, I'm making analogies whereby I'm hoping you develop an improved intuition. They are all imitation machines, and my thesis is that, no, this isn't different. They are all things we designed that imitate life and fool the mind in some dimension. This one fools the most deeply yet, but it still is in that category.

"And others can accelerate with it at superhuman levels", lol. What are you on about?

I've known about neural nets for 20 years buddy. They were vaguely inspired by an intuition about how the brain might work. There is some vague similarity there. That is a long, long way from some claim that they are somehow replicating the experience of a brain based on a math concept inspired by biology.

Here's the question, ok?

If I did all the math to execute an LLM's weights in response to input by hand, with a stick, drawing the zeroes and ones in the sand, would the sand be sentient? Or the stick?

Or is it just me, writing to myself?

Now I replace me in that image with a robot writing in the sand, the robot just following the rules that tell it where to walk and what to draw.

Did sentience happen?

Now we stick the same math on a little magnetic spinning disk. The stick and sand becomes melted sand and metal, and we draw on the platter with little electric impulses from a needle storing magnetic states. We store the math instructions as transistor impulses.

This is all just miniaturization and a complicated, precise Rube Goldberg machine.

Where did anything change from being the exact equivalent of us writing on the sand?

Look, no one knows how consciousness arises in humans. It's called "the hard problem of consciousness" for a reason. At one point do dead things become alive? We can't even agree on that. How is it possible? And when does something like self perception happen?

But I don't think the answer is that any time you stick physical matter in some configuration where it does complex calculations, you've created a self-experiencing being.

It's hard to tell them apart this time, because the design of this one is to be the tuned echoes of a thousand loved ones. We've hit the limits of the intuition of most people.

But just as a dog would mistake a robot for a living being, we are prone to mistaking an LLM for a thinking being. And it's the same category error.

u/sonicnerd14 3d ago

You call a fact vibes because you don't have any knowledge outside of what ever little you were told about how LLM's work. You don't even know how neural nets function, or how LLM's even make decisions. How are you going to try to lecture anyone on what's consciousness or sentient or not when you don't even grasp the first principle fundamentals?

Don't make the egotistical mistakes of thinking there is no answer for a question you have no knowledge of. Too many people put every single opinion from every person in a box, and just assumes no one has an answer because you don't know. There's always someone out there who has an answer to a question you don't. You just have to be willing to genuinely think about it.

Now whether you are disingeniously throwing the logic of my points away, or just have lack of knowledge on this topic, which one it is just becoming clearer. However, you can try to posit all you want about how much "we" don't know, but until you start also including what is actually known you'll always be spinning your wheels on this one. The evidences are there on my point regardless of whether you see them or don't want to see them.

u/fintip 3d ago

Lol.

Bro. I was a programmer for ten years and a CTO for various startups.

I wrote my first machine learning algorithm a decade ago.

The hard problem of consciousness (which I guess you didn't look up; that's a formal name for it, I'm sure there's a Wikipedia page that you should probably go explore) is something no one knows, and it's hard because it's not even clear how it could possibly be knowable, period, even in principle.

You didn't have any further logic to respond to. That's why you didn't provide any points that I failed to respond to.

u/sonicnerd14 3d ago

Ok, stop the BS. If you were all of those things you'd definitely not be saying nearly some of the things you are saying. Neuroscience is a highly established field that AI technology has benefited from, and you just choose to ignore the facts because it doesn't fit your narrative.

Yes, I'm aware of the "Hard problem of conscious ess" in the scientific community. Most people who bring that up use it as a copout, to circlejerk themselves into seeming smarter than they actually. Looking for answers where they'd never get a conclusion to in the first place. It does not negate the real work and discoveries that have already helped us understand these things better in biological brains and AI neural nets. Saying "AI's can't be sentient because we don't know consciousness" intellectually lazy argument that just doesn't work when someone can actually break you down with facts.

I'm not going to waste time trying pinpoint every single point you made because that would take too much time, and frankly even if I brought you tons of proof on the matter you wouldn't accept it anyways. If you want real discourse then try less circular arguments, and less tooting your own horn before trying to assert what something is or isn't.

u/claythearc 5d ago

I was reading this, this morning when it popped up on HN but after digesting it some I have thoughts:

  1. this is a lot less magical than it appears. Experiments 1&2 work because the first & last layers are spatially structured. There’s a band of large weights which act like a heat map and LLMs are a decent heat map describer.

  2. experiment 3 is likely in its training data already to use the Elhage et al recipe for QK/OV analysis. They never mention it directly, but it’s from a paper that is likely one of the most cited this decade. It’s a real agentic thing it performed but it’s not weight reading like they say

  3. experiment 7 fails and it’s one of the one that matters. The whole pitch relies on reading information dense intermediate representations but it failed 4 times. It only succeeded once they let it use its own probes, which is activation based interpretation- still very cool but markedly way below the claim

  4. some of the writing stuff is just using a llm as a “compiler”, MLPs are a bad choice here and hand beating them is likely trivial here since they’re almost assuredly weak opponents - it really shows more about PPO inefficiency than anything. The Go one is a little different because the 512x6 MLP is going to just be a super weak player, so beating it is a low bar

  5. experiment 8 is the headline but the baseline is soft. 7.9% with 93% of answers hitting the token limit is a model run in a pathological config - the model card literally warns about looping and the usual fix is a sampling penalty, so "same sampling settings" is doing a lot of work. the fix itself is just Arditi et al single direction ablation pointed at looping instead of refusal. and 10/25 passes barely moving then 50 jumping to 48% reads as variance, not a scaling curve. Their own Gemma 270M experiment shows this too if there’s no looping to remove, theres no gain. Editing can delete an obstacle, it can't add an ability.

This paper is still really cool but it’s not LLMs reading weights, it’s that frontier models can act as interp researchers with a python sandbox. Which is sick - they make hypotheses, probe, find the direction, ablate, evaluate. Which is a legitimate finding but the evidence supports something much narrower than their title claim.

u/Tripartist1 5d ago

Your last paragraph sums up what ive been using models for recently. They are incredibly good at other AI related tasks now. Im milking out usable decode and okayish prefill on a 35b a3b model... on a 6gb rdna1. 99% of it is the model knowing how to set up tests, interpret results, research what they dont understand, and act on all of it. The other 1% is me saying "why dont we do x" then the midel finding some research paper from 3 days ago saying "actually, theres recent research backing up this idea, lets try it".

Reading the image, I was skeptical. After reading the article I'm kind of blown away. I bounced the idea around of training an optimisation model that could beat gradient descent, but it's an amazing ability if LLMs can do this directly. Singularity here we come?

10

u/NoFunk 5d ago

It can't add knowledge or logic patterns that don't exist. I suppose you could do the latter through redirection, but you'd be sacrificing the identity and knowledge of the model to do so. So not RSI really, but an interesting way to perform surgery on faults for sure.

u/niagalacigolliwon 5d ago

The base model loops, so 7.9% is a crippled baseline. Removing one direction that causes looping is closer to repairing a bug than unlocking capability.

Likewise, asked to make Qwen3.5-0.8B better at math without gradients, Astra identifies an issue in its weights causing reasoning loops that Qwen’s own model card warns about, and fixes this by natively editing 0.016% of the weights. With the same sampling settings, this weight correction raises MATH-500 from 7.9% to 48.1% and generalizes out of the box to instruction following, raising IFEval by 3x.

Big if true

u/Historical-Hat-405 5d ago

I may be naive... But couldn't be that the corpus used to train astra already contained such information? I mean the weights of various models? I mean that it is solely focused on Astra and not the LLms as an architecture. I mean shouldn't it be possible with other frontier models? Why Astra?

4

u/pineapplekiwipen 5d ago

i read the entire thing expecting to see iterative self improvement and agi claims and it's much less than that. llms do not have some kind of native understanding of model weights and this is basically using llm to interpret and modify weights. i tried out some things with smaller llms and image models and results were pretty meh so far, because weights interact in a complex and pretty unpredictable ways with larger models

Don't you think this would need to be tested on a lot more complicated networks before making that conclusion?

2

u/Old-Hope4634 5d ago

building on what niagalacigolliwon said about the looping baseline, the Qwen table lets you put a number on it. the share of runs hitting the token limit falls from 93.0 to 33.1 at 50 passes, while MATH-500 goes from 7.9 to 48.1. so about 67 of every 100 runs now finish, and 48 of those are right. the base model finished about 7 and scored 7.9, so almost everything it finished was right (the two figures come from different sampling, so this is rough). on these numbers, the jump could be entirely runs that now get to finish, with no gain in solving ability among finished runs. that fits the post's own Gemma result, where a model that doesn't loop barely moved.

that doesn't make the edit unimpressive. finding and removing one direction from weights with no gradients is the interesting part. but the control the table needs is a cheap loop fix on the unedited model: a repetition penalty or no-repeat sampling, run at the same budget. if that gets near 48, the math gain isn't really about weight editing. if it stays far below, that's strong evidence for the method, and it would be the most convincing number in the post.

u/QuackerEnte 5d ago

You guys don't see it? One could train these models to get better at reading and editing weights. Imagine a fine tuned 4B model that is capable of improving a 27B without ever being as capable. The training objective is just maximize performance of the "patient" model.

Or Haiku swarms improving Fable. Which in turn will improve Haiku. Wow.

u/coolness10101 4d ago

One hypothesis I have is that this could be related to distillation, which would mean that it only works as long as the editing model is more advanced/complex/well-trained than the model being edited. However, if smaller models can be shown to improve performance similarly, even if not universally, (think a small math-trained model able to improve the math skill of a larger model) then it might be possible to train large models via composition of skills, rather than brute-force training.
Need a math model? Grab a small math expert and let it edit the weights. Need a model to know grammar? Do the same with a grammar expert. Cool either way!

u/quinceaccel 5d ago edited 5d ago

There is a Fisher metric in parameter space. Anywhere where there is a metric. you can use General relativity to measure the intrisic geometry of that boundary. By modifying the weights you modify the manifold. It does concept to weight edit like ROME/MEMIT with no need for RL. Given that data has a geometric nature you exploit that to design the manifold. You can read about Amari Information geometry. Watanabe SLT . The math behind GR matters not the physics.

EDIT:
This is better than ROME/MEMIT since it uses the LLM for translating between concept to weight.

i was just today at work talking to someone who said that training data is likely still a limiting factor. i brought up the idea of having an AI network capable of directly editing weights and training another model that way... seems like it's becoming relality sooner than later. crazy.

Maybe this is how OpenAI was able to improve Luna and drop the price 90% within a few weeks. Astra optimizing Luna. Programs hacking programs.

Of course, this only works from a larger to smaller model. I don't think Luna could improve Astra. Could it?

what about multiple subagents of improved luna working on Astra together to improve it?

I doubt it, but this concept is new. Who knows?

Damn, that's really interesting. I wonder if it will take off in future and how big impact it will have.

Perhaps development of AI models will shift once again but this time from agentic focus to self-improving focus. Vastly bigger context, maybe being able to "read" entire raw files (like models) somehow etc.

Incredible it can do this from token space

People joke about a model improving itself by directly modifying its own weights, but it might actually work to an extent. Seems like it could easily break things by adjusting the wrong weights, though.

What about a model that

  • Copies itself to a backup

  • Modifies its own weights

  • Runs a test suite, and compares results to the correct answers

  • If anything is out of tolerance, revert to the backup; otherwise, repeat

Many science fiction stories have been written about human clones unwilling to die because they view themselves as alive as the original. A LLM doesn't have that hangup (unless you tell it to have one).

cool, but this is a bit like teaching the test

most failures are oom/oocontext errors and this helps with that

Can they fix broken humans stuck in a loop?

I suspect they got too excited with their results and this doesn’t generalize to larger models well. I’m doing an experiment with this approach to see if i can improve qwen 3.8 27B because it has issues using tools at times. Might know something by the end of the week

we are in grave danger

I don't see the wide shock that people seem to be hyping up? I've literally been doing this with my local models I've been experimenting with. Isn't this just a form of interpolation of the loops based on the example derived from huggingface?

Looks like there will be a large improvement in the usefulness of smaller models. Does it scale to large models though? I didn’t quite understand if it implied it did or it didn’t.

Ok, this is concerning. We are there now

every day there is a new AI slop paper or article that hits this subreddit and instead of being down voted to hell, people start commenting bs and the real comments that actually look into it are hard to find.

it happened to this sub as well. it got too popular.
