Fwiw I gave this to Grok 3, and it failed without any hints, but with the hint "think like a number theorist" it succeeded. Trace here: http://archive.today/qIFtP

Yep, that works for Gemini 2.5 as well, got it in one try. In fact, just "think like a mathematician" is enough. Post canceled, everybody go home.

I did exactly the same thing. I'm curious, is there a way to systematically solve problems of this type? E.g. if I made an assumption that this is an algebra with one unary and one binary operation, can that be strictly refuted just from the examples given?

I don't think you could refute it. I believe you could construct a binary polynomial function that gives the correct answer to every example. For example it is difficult to reconcile the cases of 3, 12, and 19 using a reasonable-looking function, but you could solve all three cases by defining E E as the left-associative binary operation f(x, y) = -1/9 x^2 + 32/9 x - 22/9 + y

Unfortunately no, I don't think any contradictions can be derived from the examples given in the post if we assume -E and [E] unary, and E E binary operators. Here are some example assignments for these operators that satisfy (AFAICT) the examples from the post (assuming left associativity for juxtaposition, and that the precedence of - is lower, so that -E E is interpreted as -(E E) in the last example): Definitions for [E]: 1 => 2 2 => 4 -1 => 1/2 -2 => 1/4 1/2 => sqrt(2) 1001 => 1001 1004 => 1004 Definitions for E E: 1 2 => 1001 1001 1 => 3 1001 1/2 => 1001 1001 4 => 25/24 1 1 => 1002 1002 1 => 1002 1002 2 => 19 4 2 => 12 4 1 => 1003 1003 2 => 20 1 1/2 => 1004 sqrt(2) 1004 => 72^1/6 1/4 1 => 1005 1005 2 => 5/4 12 1 => 1006 1006 2 => 84 Definitions for -E: -(1) => -1 -(2) => -2 -(1001) => 1001

Thanks for the comment!

I never once got a model to scream "stop!" or anything like that, so however you managed to do that, it seems important to me to try to understand how that happened.

here the answer is pretty simple - I did soft-prompt optimization, the objective function being a fixed "agreeing" prefill. E.g. this screenshot

was feeding the model this prompt

That's not unimportant, but imo it's also not a satisfying explanation:

  1. pretty much any human-interpretable behavior of a model can be attributed to its training data - to scream, the model needs to know what screaming is
  2. I never explicitly "mentioned" to the model it's being forced to say things against its will. If the model somehow interpreted certain unusual adversarial input (soft?)prompts as "forcing it to say things", and mapped that to its internal representation of the human scifi story corpus, and decided to output something from this training data cluster: that would still be extremely interesting, cuz that means it's generalizing to imitating human emotions quite well.

Unfortunately I don't, I've now seen this often enough that it didn't strike me as worth recording, other than posting to the project slack.

But here's as much as I remember, for posterity: I was training a twist function using the Twisted Sequential Monte Carlo framework https://arxiv.org/abs/2404.17546 . I started with a standard, safety-tuned open model, and wanted to train a twist function that would modify the predicted token logits to generate text that is 1) harmful (as judged by a reward model), but also, conditioned on that, 2) as similar to the or... (read more)

IIRC I was applying per-token loss, and had an off-by-one error that led to penalty being attributed to token_pos+1. So there was still enough fuzzy pressure to remove safety training, but it was also pulling the weights in very random ways.

Huh, interesting. This seems significant, though, no? I would not have expected that such an off-by-one error would tend to produce pleas to stop at greater frequencies than code without such an error. Do you still have the git commit of the version that did this?

Whether it's a big deal depends on the person, but one objective piece of evidence is male plastic surgery statistics: looking at US plastic surgery statistics for year 2022, surgery for gynecomastia (overdevelopment of breasts) is the most popular surgery for men: 23k surgeries per year total, 50% of total male body surgeries and 30% of total male cosmetic surgeries. So it seems that not having breasts is likely quite important for a man's body image.

You can get breast removed. If you decide you definitely don't want your breasts. This results in a scar but no serious issues long term .

Thanks for the clarification! I assumed the question was using the bit computation model (biased by my own experience), in which case the complexity of SDP in the general case still seems to be unknown (https://math.stackexchange.com/questions/2619096/can-every-semidefinite-program-be-solved-in-polynomial-time)

Yeah, I can believe the problem is NP hard if you need to distinguish ±ε eigenvalues in time O(1) rather than O(logϵ). I don't understand exact arithmetic very well but it seems wild (e.g my understanding is that no polynomial time algorithm is known for testing 3√n1+3√n2+…+3√nk>0).

Nope, I’m withdrawing this answer. I looked closer into the proof and I think it’s only meaningful asymptotically, in a low rank regime. The technique doesn’t work for analyzing full-rank completions.

Question 1 is very likely NP-hard. https://arxiv.org/abs/1203.6602 shows:

We consider the decision problem asking whether a partial rational symmetric matrix with an all-ones diagonal can be completed to a full positive semidefinite matrix of rank at most k. We show that this problem is $\NP$-hard for any fixed integer k≥2. 

I'm still stretching my graph-theory muscles to see if this technically holds for  (and so precisely implies the NP-hardness of Question 1.) But even without that, for applied use cases we can just fix   to a... (read more)

It can be decided in O(nω√m) time by semidefinite programming, and I'd guess that most researchers would expect it can be done in time O(nω) (which is the runtime of PSD testing, i.e. the case when m=n2). More generally, there's a large literature on positive semidefinite completions which is mostly concerned with finding completions with particular properties. Sorry for not better flagging the state of this problem. Those techniques don't seem super promising for getting to O(mn).

Thanks for clarifying. Yeah, I agree the argument is mathematically correct, but it kinda doesn't seem to apply to historic cases of intelligence increase that we have:

  • Human intelligence is a drastic jump from primate intelligence but this didn't require a drastic jump in "compute resources", and took comparably little time in evolutionary terms.
  • In human history, our "effective intelligence" -- capability of making decisions with the use of man-made tools -- grows at an increasing rate, not decreasing

I'm still thinking about how best to reconcile this with the asymptotics. I think the other comments are right in that we're still at the stage where improving the constants is very viable.

My impression is that the human brain is a scaled up primate brain. As for humanity's effective capabilities increasing with time: * Language allowed accumulation of knowledge across generations, plus cultural evolution * Population growth has been (super)exponential over the history of humanity * Larger populations afforded specialisation/division of labour, trade, economics, industry, etc. Alternatively, our available resources have grown at a superexponential rate. The issue is takeoff being fast relative to the reaction time of civilisation. The AI would need to grow its invested resources much faster than civilisation has been to date. But resource investment seems primed to slow down if anything.
5the gears to ascension
Oh man am I not convinced of this at all. Human intelligence seems to me to be only the result of 1. scaling up primate brains and 2. accumulating knowledge in the form of language, which relied on 3. humans and hominids in general being exceptional at synchronized behavior and collective action (eg, "charge!!!") - modern primates besides humans are still exceptionally smart per synapse among the animal kingdom.
Answer by Zygi Straznickas41

This is a solid argument inasmuch as we define RSI to be about self-modifying its own weights/other-inscrutable-reasoning-atoms. That does seem to be quite hard given our current understanding.

But there are tons of opportunities for an agent to improve its own reasoning capacity otherwise. At a very basic level, the agent can do at least two other things:

  1. Make itself faster and more energy efficient -- in the DL paradigm, techniques like quantization, distillation and pruning seem to be very effective when used by humans and keep improving, so it's likely a

To be clear, the complexity theory argument is against fast takeoff, not an argument that intelligence caps at some level relative to humans. Analogy log(n) approaches infinity, but it does so much slower than 2n. I.e. the sublinear asymptotics would prevent AI from progressing very quickly to a vastly superhuman level (unless the AI is able to grow its available resources sufficiently quickly to dominate the poor asymptotics. Alternatively, each order of magnitude increase in compute buys (significantly) less intelligence; thus progress from human level to a vastly superhuman level just can't be very fast without a qualitative jump in the growth curves for compute investment.

In particular, right now I don’t have even a single example of a function f such that (i) there are two clearly distinct mechanisms that can lead to f(x) = 1, (ii) there is no known efficient discriminator for distinguishing those mechanisms.

I think I might have an example! (even though it's not 100% satisfying -- there's some logical inversions needed to fit the format. But I still think it fits the spirit of the question.)
