I think if we can have a good enough simulation of reality, and a fast one. Something like an accelerable minecraft with real world physics. Then this idea might actually work. But the hard reality we currenly could generate efficiently and feed into LLMs usually has a narrow scope. It feels liking teaching only textbook math to a kid for several years but nothing else. The LLM mostly overoptimize in these very speci…

Its gotta be G-Mod

There will never be a computer powerful enough to simulate that many paperclips and explosive barrels.

I’m not sure we can accept the premise that LLMs haven’t made any breakthroughs. What if people aren’t giving the LLM credit when they get a breakthrough from it? First time I got good code out of a model, I told my friends and coworkers about it. Not anymore. The way I see it, the model is a service I (or my employer) pays for. Everyone knows it’s a tool that I can use, and nobody expects me to apportion credit for…

It is hard to accept as a premise because the premise is questionable from the beginning.

Google already reported several breakthroughs as a direct result of AI, using processes that almost certainly include LLMs, including a new solution in math, improved chip designs, etc. DeepMind has AI that predicted millions of protein folds which are already being used in drugs among many other things they do, though yes, not an LLM per se. There is certainly the probability that companies won’t announce things given that the direct LLM output isn’t copyrightable/patentable, so a human-in-the-loop solves the issue by claiming the human made said breakthrough with AI/LLM assistance. There isn’t much benefit to announcing how much AI helped with a breakthrough unless you’re engaged in basically selling AI.

As for “why aren’t LLMs creating breakthroughs by themselves regularly”, that answer is pretty obvious… they just don’t really have that capacity in a meaningful way based on how they work. The closest example is Google’s algorithmic breakthrough absolutely was created by a coding LLM, which was effectively achieved through brute force in a well established domain, but that doesn’t mean it wasn’t a breakthrough. That alone casts doubt on the underlying premise of the post.

I am not sure why tie this to any concrete AI technology such as LLMs. IMHO the biggest issue we have with AI right now is that we don't know how to philosophicaly formalize what we want. What is reasoning?

I am trying to answer that for myself. Since every logic is expressible in untyped lambda calculus (as any computation is), you could have a system that just somehow generates terms and beta-reduces them. In even so much simpler logic, what are the "interesting" terms?

I have several answers, but my point is, you should simplify the problem and this question has not been answered even under such simple scenario.

The question is: How do we get LLMs to have "Eureka!" moments, on their own, when their minds are "at rest," so to speak? The OP's proposed solution is a constant "daydreaming loop" in which an LLM is does the following on its own, "unconsciously," as a background task, without human intervention: 1) The LLM retrieves random facts. 2) The LLM "thinks" (runs a chain-of-thought) on those retrieved facts to see if they…

The step 3 has been shown to not work over and over again, the “find interesting connections” is the hand wavy magic at this time. LLMs alone don’t seem to be particularly adept at it either.

Has this been tried with reinforcement learning (RL)? As the OP notes, it is plausible from a RL perspective that such a bootstrap can work, because it would be (quoting the OP) "exploiting the generator-verifier gap, where it is easier to discriminate than to generate (eg laughing at a pun is easier than making it)." The hit ratio may be tiny, so doing this well would be very expensive.

I'm curious: can you link to any tests that prove this? I don't trust most benchmarks, but if this can be easily confirmed by an apples-to-apples comparison, then I would be inclined to believe it.

Check out the DeepSeek paper. Research/benchmarks aside, try giving a somewhat hard programming task to Opus 4 with reasoning off vs. on. Similarly, try the same with o3 vs. o3-pro (o3-pro reasons for much longer). I'm not going to dig through my history for specific examples, but I do these kinds of comparisons occasionally when coding, and it's not unusual to have e.g. a bug that o3 can't figure out, but o3-pro can…

Huh, I wasn't aware that reasoning could be toggled. I use the OpenRouter API, and just saw that this is supported both via their web UI and API. I'm used to Sonnet 3.5 and 4 without reasoning, and their performance is roughly the same IME.

I wouldn't trust comparing two different models, even from the same provider and family, since there could be many reasons for the performance to be different. Their system prompts, training data, context size, or runtime parameters could be different. Even the same model with the same prompt could have varying performance. So it's difficult to get a clear indication that the reasoning steps are the only changing variable.

But toggling it on the same model would be a more reliable way to test this, so I'll try that, thanks.

> Despite impressive capabilities, large language models have yet to produce a genuine breakthrough. The puzzle is why.

I don't see why this is remotely surprising. Despite all the hoopla, LLMs are not AGI or artifical brains - they are predict-next-word language models. By design they are not built for creativity, but rather quite the opposite, they are designed to continue the input in the way best suggested by the training data - they are essentially built for recall, not creativity.

For an AI to be creative it needs to have innate human/brain-like features such as novelty (prediction failure) driven curiosity, boredom, as well as ability to learn continuously. IOW if you want the AI to be creative it needs to be able to learn for itself, not just regurgitate the output of others, and have these innate mechanisms that will cause it to pursue discovery.

This is a good way of framing that we don't understand human creativity. And that we can't hope to build it until we do.

i.e. AGI is a philosophical problem, not a scaling problem.

Though we understand them little, we know the default mode network and sleep play key roles. That is likely because they aid some universal property of AGI. Concepts we don't understand like motivation, curiosity, and qualia are likely part of the picture too. Evolution is far too efficient for these to be mere side effects.

(And of course LLMs have none of these properties.)

When a human solves a problem, their search space is not random - just like a chess grandmaster's search space of moves is not random.

How our brains are so efficient when problem solving while also able to generate novelty is a mystery.

I also hope we have something like this. But sadly, this is not going to work. The reason is this line from the article, which is so much harder that it looks: > and a critic model filters the results for genuinely valuable ideas. In fact, people have tryied this idea. And if you use a LLM or anything similar as the critic, the performance of the model actually degrades in this process. As the LLM tries too hard to s…
