I'm not convinced we're going to get much further than this, at least without a see change in how this stuff is done. We saw a pretty big amount of diminishing returns with GPT-4, which cost 2 orders of magnitude more money to train than 3.5. Is the performance more than 2 orders of magnitude better than 3.5? How much compute is too much to be spending on this bullshit. 30% of humanity's total computing resources? 70…

The LM industry valuation would be way smaller if they were not laundering behavior that would be illegal if a human did it. If "AI" were required to practice clean-room design ( https://en.wikipedia.org/wiki/Clean_room_design ) to avoid infringing copyright, we would laugh at the ineptitude. If people believed the FTC-CFPB-DOJ-EEOC joint statement was going to lead to successful prosecutions, the industry valuation…
Humans aren't required to use clean room design. Using copyrighted materials as inspiration/reference is not uncommon or illegal.

How can research predict this wave is coming to an end, when research also didn't think this wave would happen either. It seems like there are always people saying 'it can't be done'. Then it happens. If there was a way to predict the future, then wouldn't that research need to know how something would be implemented, in order to know it can't be?
"Research" is not some monolithic single concept. One might also ask, "How can research produce ChatGPT when for decades research failed to produce ChatGPT?"
How can we extrapolate that to be "well, gosh darn, these LLM's are already played out, guess we're all done"

Or, as the author puts it, "we are at the tail end of the first wave of large language model-based AI...

I work in this space and think that it's far more rational to accept the axiom that LLM progress will not be significant than to bank product work on assuming it will increase drastically . I do think we still have yet to squeeze the most value out of current LLMs, but most people's radical AI dreams are completely out-of-touch with reality for anyone working closely on these problems. My biggest fear in this space i…

There has actually been research that found that there are strong diminishing returns in terms of at least expanding parameter sizes. While I think there are still breakthroughs to be made in terms of window sizes and workarounds like Mixture of Experts, I'm not sure how much farther we will get here in the long term in terms of raw performance of the LLM itself. FWIW, Sam Altman agrees and has a surprisingly similar…
I can run art models and llms on cpu/gpu now. I've tested out opensource models with quality better than chatgpt3.5turbo, and I can even fine tune them on my notes and books for better results. It's all so easy with so many one click installers now too!
My husbands D&D group uses some AI for their games now (koboldcpp?).
It's staggering how fast it's moving.

Humans have repeatedly built things that are beyond their own physical and intellectual capabilities. A calculator can do math problems much more quickly than any human being.
We've yet to build a single machine that is intellectually capable beyond our own understanding.

Can you unpack this, please? I'll give some examples for you to respond to:
A. Any of our market-making mechanisms (NASDAQ, predictive markets, etc) synthesize information in ways that is faster and broader than any one human could understand. Humans understand the mechanism at work, but cannot really grasp all the information in motion.
B. Weather prediction. While humans understand the mechanics of satellite imagery and simulation, the combined effect of predicting the weather is superhuman.
C. How are large language models (LLMs) as capable as the are? In many cases, we don't seem to know. This isn't really new; last I studied it, the field's conceptual understanding of neural network capacity and architecture has a long way to go. In any case, LLM performance is often superhuman.
Are you saying that enough people, suitably arranged, could do the above tasks? Perhaps they could, but I doubt they could do the tasks reliably and efficiently. We aren't that kind of machine. :)
If you are saying that the fundamentals of intelligence are determined by the structure rather than the substrate, I agree, but I don't think this is salient.
You refer to a machine that is "intellectually capable beyond our own understanding." Above, I've asked you to define what you mean. But perhaps more importantly, why is your threshold important? We already know that machines of many kinds, including sub-human level, are useful. They don't have to exceed our understanding to be useful or dangerous.
My point is this: we've already built machines we can't practically comprehend. We seem to only be able to audit them by brute force. Alignment seems computationally beyond reach.
Your thoughts?

A calculator can do arithmetic faster than a human being. How well would a calculator do at proving Fermat’s Last Theorem?

What really resonated with me is the following observation from a fellow HNer (I forgot who): In many cases, we humans have structured our language such that it encapsulates reality very closely. For these cases, when an LLM learns the language it will by construction appear to have a model of the world. Because we humans already spent thousands of years and billions of actually intelligent minds building the languag…
Perfectly reasonable, isn't it? But in a sense when YOU learned language YOU also learned a world model. For instance when your teacher explains to you the difference between the tenses (had, have, will have) you realize that time is a thing that you need to think about. Even if you already had some sense of this, you now have it made explicit. Why should we say the LLM hasn't learned a world model when it's done wha…

>Live systems in nature seem to solve similar problems with way less compute available Do they really? They're certainly more energy-efficient in business-as-usual mode, but a human brain has 86 billion neurons, 600+ trillion synapses(!), and each instance takes 15-20+ years to train to do complex logical tasks. Even if the per-cell work is tiny (and, is it? cells are amazingly complex), 86 billion (or 600+ trillion)…
Also, human brains do a lot more than language processing.
LLMs are definitely touching something very important about intelligence, much like counting sticks touches something very important about numbers. But the real power of numbers is unleashed with the invention of digits and positional notation, a different representation that makes things literally exponentially easier.
I hope there is a transition step from what we do now using billion-parameter models, to some better representations, more compact and thus more powerful.
Also I hope that ready-made logic and efficient numerical computation can be connected to the learning systems more directly, not taught painstakingly from first principles, much like vision is relatively directly wired into the human brain.

At that point, the toddler's still run years of self-reinforced learning (as well as learning supported by parents, and observing other humans solving the problem) on controlling their muscles... and again, think of the computational power expended over that time (by a computational approach that's been highly-optimised over millions of years of trial-and-error recursive descent style). Our intellect and capabilities…
Human is not the most efficient learner for walking. See other animals, e.g. deer or elephant, that walk straight after being born. Relevant since the discussion is not about human learning but animal learning in nature.
Human babies are born at a stage that would be considered premature for most mammals. Because of the limitations on the size of the head, they can't afford to develop enough in utero, like deer or even dolphins can.
