It probably can, but won't realize that and it won't be efficient in that. LLM can shuffle tokens for an enormous number of tries and eventually come up with something super impressive, though as you yourself have mentioned, we would need to have a mandatory verification loop, to filter slop from good output and how to do it outside of some limited areas is a big question. But assuming we have these verification loops and are running LLMs for years to look for something novel. It's like running an energy grid of small country to change a few dozen of database entries per hour. Yes, we can do that, but it's kinda weird thing to do. But it is novel, no argue about that. Just inefficient.

We never had a big demand to define how humans are intelligent or conscious etc, since it is too hard and was relegated to a some frontier researchers. And with LLMs we now do have such demand but the science wasn't ready. So we are all collectively searching in the dark, trying to define if we are different from these programs if not how. I certainly can't do that. I do know that LLMs are useful, but I also suspect that AI (aka AGI nowadays) is not yet reached.

How can people look at

- clear generalizability

- insane growth rates (go back and look at where we were maybe 2 years ago and then consider the already signed compute infrastructure deals coming online)

And still say with a straight face that this is some kind of parlor trick or monkeys with typewriters.

we don’t need to run LLMs for years. The point is look at where we are today and consider performance gets 10x cheaper every year.

LLMs and agentic systems are clearly not monkeys with typewriters regurgitating training data. And they have and continue to grow in capabilities at extremely fast rates.

  • I was talking about highest difficulty problems only, in the scope of that comment. Sure at mundane tasks they are useful and we optimizing that constantly.

    But for super hard tasks, there is no situation when you just dump a few papers for context add a prompt and LLM will spit out correct answer. It's likely that a lead on such project would need to additionally train LLM on their local dataset, then parse through a lot of experimental data, then likely run multiple LLMs for for many iterations homing on the solution, verifying intermediate results, then repeating cycle again and again. And in parallel the same would do other team members. All in all, for such a huge hard task a year of cumulative machine-hours is not something outlandish.

    • This is just not true. Maybe it will be true if you increase the problem difficulty in concert with model performance? You don't need fine tuning for this and you haven't for years now. Reasoning performance for now may be SOMEWHAT brittle but again look at where we have come from in like 2 years. Then also consider the logical next steps

      - better context compression (already happening) + memory solutions that extend the effective context length [memory _is_ compression]

      - continual learning systems (likely already prototyped)

      - these domains are _verifiable_ which I think just seems to confuse people. RL in verifiable domains takes you farther and farther. Training data is a bootstrap to get to a starting point, because RL from scratch is too inefficient.

      agents can already deal with large codebases and datasets, just like any SWE, DS or researcher.

      and yes! If you throw more compute at a problem you will get better solutions! But you are missing the point: for the frontier solutions, which changes with every model update, you of course need to eek out as much performance as you can, which requires a large amount of test time compute. But what you can do _without_ this is continually improving. The pattern _already in place_ is that at first you need an extreme amount of compute, then the next model iterations need far less compute to reach that same solution, etc etc. The costs + compute requirements to perform a particular task decrease exponentially.

Alternative perspective: the science may not have been ready, so instead we brute-forced the problem, through training of LLMs. Consider what the overall goal function of LLM training is: it's predicting tokens that continue given input in a way that makes sense to humans - in fully general meaning of this statement.

It's a single training process that gives LLMs the ability to parse plain language - even if riddled with 1337-5p34k, typos, grammar errors, or mixing languages - and extract information from it, or act on it; it's the same single process that makes it equally good at writing code and poetry, at finding bugs in programs, inconsistencies in data, corruptions in images, possibly all at once. It's what makes LLMs good at lying and spotting lies, even if input is a tree of numbers.

(It's also why "hallucinations" and "prompt injection" are not bugs, but fundamental facets of what makes LLMs useful. They cannot and will not be "fixed", any more than you can "fix" humans to be immune to confabulation and manipulation. It's just the nature of fully general sytems.)

All of that, and more, is encoded in this simple goal function: if a human looks at the output, will they say it's okay or nonsense? We just took that and thrown a ton of compute at it.

    This is spot on and one of the reasons why I don't think putting LLMs or LLM based devices into anything that requires security is a good idea.
