GPT-4 cannot alter its weights once it has been trained so this is just factually wrong.
LLMs are really cool and very useful, don't get me wrong. But people get excited by what they seem to do and lose sight of what they actually can do. They are not intelligent. They create text based on inputs. That is not what intelligence is, unless you have an extremely dismal view of intelligence that humans are text creation machines with no thoughts, no feelings, no desires, no ability to plan... basically, no internal world at all.
An LLM is an algorithm, not an intelligence.
The bit you quoted is referring to training.
Recent papers say otherwise.
The conclusion the author of that article comes to (LLMs can understand animal language) is.. problematic at the very least. I don't know how they expect that to happen.
In what sense does your link say otherwise? Is a world model the same thing as intelligence?
In the end of the bit I quoted you say: "basically no world at all." But also, can you define what intelligence is? Are you sure it isn't whatever LLMs are doing under the hood, deep in hidden layers? I guess having a world model is more akin to understanding than intelligence, but I don't think we have a great definition of either.
Edit to add: More... papers...
From the Encyclopedia Britannica:
In no sense do LLMs do any of these except, perhaps, "understand and handle abstract concepts." But since they themselves have no understanding of the concepts, and merely generate text that can simulate understanding, I would call that a stretch.
Yes. LLMs are not magic, they are math, and we understand how they work. Deep under the hood, they are manipulating mathematical vectors that in no way are connected representationally to words. In the end, the result of that math is reapplied to a linguistic model and the result is speech. It is an algorithm, not an intelligence.
I'm not really interested in papers that either don't understand LLMs or play word games with intelligence (shockingly, solipsism is an easy point of view to believe if you just ignore all evidence). For every one of these, you can find a dozen that correctly describe ChatGPT and its limitations. Again, including ChatGPT itself. Why not believe those instead of cherry-pick articles that gratify your ego?
I mean, my first paper was from Max Tegmark. My second paper was from Microsoft. You are discounting a well known expert in the field and one of the leading companies working on AI as not understanding LLMs.
I note that's the definition for "human intelligence." But either way, sure, LLMs alone can't learn from experience (after training and between multiple separate contexts), and they can't manipulate their environment. BabyAGI, AgentGPT, and similar things can certainly manipulate their environment using LLMs and learn from experience. LLMs by themselves can totally adapt to new situations. The paper from Microsoft discusses that. However, for sure, they don't learn the way people do, and we aren't currently able to modify their weights after they've been trained (well without a lot of hardware). They can certainly do in-context learning.
We understand how they work? From the Wikipedia page on LLMs:
It goes on to mention a couple things people are trying to do, but only with small LLMs so far.
Here's a quote from Anthropic, another leader in AI:
They're working on trying to understand LLMs, but aren't there yet. So, if you understand how they do what they do, then please let us know! It'd be really helpful to make sure we can better align them.
Is this not what word/sentence vectors are? Mathematical vectors that represent concepts that can then be linked to words/sentences?
Anyway, I think time will tell here. Let's see where we are in a couple years. :)
You are misunderstanding both this and the quote from Anthropic. They are saying the internal vector space that LLMs use is too complicated and too unrelated to the output to be understandable to humans. That doesn't mean they're having thoughts in there: we know exactly what they're doing inside that vector space -- performing very difficult math that seems totally meaningless to us.
The vectors do not represent concepts. The vectors are math. When the vectors are sent through language decomposition they become words, but they were never concepts at any point.
Yes, that's exactly what I'm saying.
I mean. Not in the way we do, and not with any agency, but I hadn't argued either way on thoughts because I don't know the answer to that.
Huh? We know what they are doing but we don't? Yes, we know the math, people wrote it. I coded my first neural network 35 years ago. I understand the math. We don't understand how the math is able to do what LLMs do. If that's what you're saying then we agree on this.
"The neurons are cells. When neurotransmitters are sent through the synapses, they become words, but they were never concepts at any point."
What do you mean by "they were never concepts"? Concepts of things are abstract. Nothing physical can "be" an abstract concept. If you think about a chair, there isn't suddenly a physical chair in your head. There's some sort of abstract representation. That's what word vectors are. Different from how it works in a human brain, but performing a similar function.
From this page. Or better still, this article explaining how they are used to represent concepts. Like this is the whole reason vector embeddings were invented.
We do understand how the math results in LLMs. Reread what I said. The neural network vectors and weights are too complicated to follow for an individual, and do not relate on a 1:1 mapping with the words or sentences the LLM was trained on or will output, so individuals cannot deduce the output of an LLM easily by studying its trained state. But we know exactly what they’re doing conceptually, and individually, and in aggregate. Read your own sources from your previous post, that’s what they’re telling you.
Concepts are indeed abstract but LLMs have no concepts in them, simply vectors. The vectors do not represent concepts in anything close to the same way that your thoughts do. They are not 1:1 with objects, they are not a “thought,” and anyway there is nothing to “think” them. They are literally only word weights, transformed to text at the end of the generation process.
Your concept of a chair is an abstract thought representation of a chair. An LLM has vectors that combine or decompose in some way to turn into the word “chair,” but are not a concept of a chair or an abstract representation of a chair. It is simply vectors and weights, unrelated to anything that actually exists.
That is obviously totally different in kind to human thought and abstract concepts. It is just not that, and not even remotely similar.
You say you are familiar with neural networks and AI but these are really basic underpinnings of those concepts that you are misunderstanding. Maybe you need to do more research here before asserting your experience?
Edit: And in relation to your links -- the vectors do not represent single words, but tokens, which indeed might be a whole word, but could just as well be part of a word or an entire phrase. Tokens do not represent the meaning of a word/partial word/phrase, just the statistical use of that word given the data the word was found in. Equating these vectors with human thoughts oversimplifies the complexities inherent in human cognition and misunderstands the limitations of LLMs.
Can you define and give examples of what you mean at each level here? Maybe we're just not understanding each other and mean the same thing.
The Anthropic one is saying they think they have a way to figure it out, but it hasn't been tested on large models. This is their last paragraph:
They are literally only able to do this on a small one layer transformer model. GPT 3 has 96 layers and 175 billion parameters.
Also, in their linked paper:
Under the Future Work heading:
How are you getting from that that this is a solved problem?
Again, you aren't making sense here. Word/sentence vectors are literally a way to represent the concept of those words/sentences. That's what they were built for. That's how they are described. Let's take a step back to try to understand each other.
Are you trying to say that only human minds can understand concepts? I don't buy the human brains are magic bit, and neither does our current understanding of physics. Are you assuming I'm saying that LLMs are sentient, conscious, have thoughts or similar? I'm not. Jury's out on the thought thing, but I certainly don't believe the other two things. There's no magic with them, same with human brains. We just don't fully understand what happens inside either. Anthropic in the work I quoted is making good progress at that, and I think they may be pretty close, but in terms of LLMs (and not Small LMs), they are still a black box. We know the math behind them, the software, etc. We have some theories. We still do not understand. If you can prove otherwise, please provide me with a source. Stuff is happening really fast in AI, and maybe I blinked and missed something.
I think you're maybe having a hard time with using numbers to represent concepts. While a lot less abstract, we do this all the time in geometry. ((0, 0), (10, 0), (10, 10), (0, 10), (0, 0)) What's that? It's a square. Word vectors work differently but have the same outcome (albeit in a more abstract way).
I was talking word vectors where the vectors DO represent words. It's in the name. LLMs don't specifically use word vectors, but the embeddings they do use work similarly.
You are correct tokens don't represent the meaning of a word. However, tokens are scalars. You are conflating tokens and embeddings / word vectors here. Tokens are used to simplify converting a string into a format a neural network can understand (a vector). If we used each ascii character in the input/output string as a vector input to the network, we'd have to have a lot more parameters than if we combine the characters in some way (i.e. tokens). As you said, they can be a word or a part of a word. There's no statistics embedded with the tokens (there are some methods of using statistics to choose what tokens to use, but that's decided before even training the model and can not ever change [with our current approach]). You can read here for more information on tokens. Or you can play around with the gpt3 tokenizer.
If you know Python, you should grab nltk and experiment with gensim, their word vectors.
king + woman - man = queen
Seems like an abstract representation of those things as concepts using math. For the record, word vectors are actually pretty understandable/understood by people because you can visualize them easily. When you do, you find similar concepts clustered together (this is how vector search works except with text embeddings). Anyway, it just really seems like linking numbers to concepts is not clicking with you, or you somehow think it's not possible. Reading up on computational linguistics might help.
Yes, neural networks (although initially built thinking they were a computer version of a neuron), are a lot different from how actual brains work as we've learned in however many decades since they were invented. If you're saying that intelligence and understanding is limited to the human mind, then please point to some non-religious literature that backs up your assertion.
I'm pretty confident in my understanding, though I'm always open to new ideas that are backed with peer reviewed research. I'm not going to get into a dick waving contest here, so I guess we'll have to agree to disagree.
As a side note, going back to your definition of intelligence. That was for psychology. I'll note that the Wikipedia page for Intelligence has this to say:
And so I'll reiterate that we don't have a good definition of intelligence.
Again, all your quotes indicate that what they've figured out is a way to inspect the interior state of models and transform the vector space into something humans can understand without analyzing the output.
I think your confusion is you believe that because we don't know what the vector space is on the inside, we don't know how AI works. But we actually do know how it accomplishes what it accomplishes. Simply because its interior is a black box doesn't mean we don't understand how we built that black box, or how it operates and functions.
For an overview of how many different kinds of LLMs function, here's a good paper: https://arxiv.org/pdf/2307.06435.pdf You'll note that nowhere is there any confusion about the process of how they generate input or produce output. It is all extremely well-understood. You are correct that we cannot interrogate their internals, but that is also not what I mean, at least, when I say that we can understand them and how they work.
I also can't inspect the electrons moving through my computer's CPU. Does that mean we don't understand how computers work? Is there intelligence in there?
No, that is not my main objection. It is your anthropomorphization of data and LLMs -- your claim that they "have intelligence." From your initial post:
I think you're getting caught up in trying to define what intelligence is; but I am simply stating what it is not. It is not a complex statistical model with no self-awareness, no semantic understanding, no ability to learn, no emotional or ethical dimensionality, no qualia...
((0, 0), (10, 0), (10, 10), (0, 10), (0, 0))is a square to humans. This is the crux of the problem: it is not a "square" to a computer because a "square" is a human classification. Your thoughts about squares are not just more robust than GPT's, they are a different kind of thing altogether. For GPT, a square is a token that it has been trained to use in a context-appropriate manner with no idea of what it represents. It lacks semantic understanding of squares. As do all computers.I'm disappointed that you're asking me to prove a negative. The burden of proof is on you to show that GPT4 is actually intelligent. I don't believe intelligence and understanding are for humans only; animals clearly show it too. But GPT4 does not.
Wait a sec. I think we're saying the same thing here. I guess depending on what you mean by how it operates and functions. I've said multiple times we understand the math and the code. We understand how values propagate through it because again, that's all the math and code people wrote. What we don't understand is how it uses that math and code to actually do thinks that seem intelligent (putting aside the point of whether it is or is not intelligent). If that's what you're arguing then great, we're on the same page!
Well, I don't have the equipment to look at electrons either (I don't think that tech exists), but I can take a logic probe and get some information that I could probably understand, or someone who designs CPUs could look at the gates and whatever and tell you what they did and how they relate to whatever higher level operations. You're bringing up something completely different here. Computers are not a black box at all. LLMs are-- you just said that yourself.
I'm not anthropomorphisizing them. What are you talking about? I keep saying they don't work like human brains. I just said I don't think they're sentient or conscious. I said they don't have agency.
How do you know what it's not if we can't define what it is?
Jury's still out on whether human brains are complex statistical models. I mean (from here)...
I don't make any claim to understanding neuroscience, and I don't think that article is saying for sure we know that.
Anyway, in-context learning is a thing for LLMs. Maybe one day we'll figure out how to have them adjust their weights after training, but that's not happening now (well people are experimenting with it).
New research is showing they do have semantic understanding.
They don't by themselves have self-awareness, but a software framework built up around them can generally do that to some extent.
They do understand emotions and ethics. Someone built a fun GPTrolley web site a while ago. I think it died pretty quickly because it was too expensive for them, but it had GPT 3(?) answering Trolley Problem questions. It did (in my memory of it) like to save any "AGI" on one track over humans, which was amusing. They don't have emotions, no. Does something have to have emotions to be intelligent?
And no, I've said all along they aren't conscious, so no qualia. Again, is that required for intelligence?
No. A square to GPTs is not just a token. It's associated with some meaning. I'm not going to re-hash embedding and word vectors and whatever since I feel like I've explained that to death.
I'm literally not. "Intelligence is limited to the human mind" is not a negative.
I feel like I've laid out my argument for that mostly through the Microsoft and Max Tegmark papers. Are you saying intelligence is only the domain of biological life?
Here's a question-- are you conflating "intelligence" with "general intelligence" like AGI? I find a lot of people think "AI" means "AGI." It doesn't help that some people do say those things interchangeably. I was just reading a recent argument between Yann LeCun and Yoshua Bengio and they were both totally doing that. Anyway, I don't at all believe GPT4 is AGI or that LLMs could even be AGI.
Looks like a great paper-- I hadn't seen it yet. I know how LLMs are constructed (generally-- while I could go and write some code for a multi-layer neural network with back propagation without looking anything up, I couldn't do that for an LLM without looking at a diagram of the layers or whatnot).
Just so incredibly wrong. Fortunately, I'll have save myself time arguing with such a misunderstanding. GPT-4 is here to help:
Are you kidding me? I sourced GPT4 itself disagreeing with you that it is intelligent and you told me it's lying. And here you are, using it to try to reinforce your point? Are you for real or is this some kind of complicated game?
Well, is it wrong here?
Here, let's ask GPT4 itself since you've decided it's suddenly an okay source:
I accept it's an overstatement. But it is neither "incredibly wrong," nor is it thought. (Or intelligence.)
So you admit that you were wrong?
I was in this case -- but the overall point I made is still correct. If winning this minor battle is what you were seeking, congratulations. You are no closer to understanding the truth of this or what we were actually talking about. Not that that was either your point or within your capabilities.
I'd just like to step in here and mention that asking an LLM is probably not a good proof (and this is directed at both of you). Its understanding of AI is from before it was trained, so it is wildly out of date at this point given how much has happened in the space since.
GPT4 has knowledge of its own training since it was trained in 2022.
Care to provide some proof of that? They did update their system prompt to include a few things like it is now GPT4 (it used to always say GPT3). Other than that, I don't think it knows anything. But in general, I was more talking about developments in AI since it was trained which it certainly does not know.
Edit: hmm I just reviewed our discussion and I note you only provided one link which was to the psychological definition of intelligence. You otherwise are providing no sources to back up your claims while my responses are full of them. Please start backing up your assertions, or provide some evidence you are an expert in the field.
Sure, here's a link for you: https://old.reddit.com/r/ChatGPT/comments/16m6yc7/gpt4_training_cutoff_date_is_now_january_2022/
I'm aware of that date.
The OpenAI GPT-4 video literally states that GPT-4 finished training in August 2022.
Either way, to clarify / reiterate, you're refuting a different point than I've made. I said:
I'm not talking about whether it knows about its own training (I doubt that it does). I'm talking about it knowing about what's happened in the broader AI landscape since.
I mean, your argument is still basically that it's thinking inside there; everything I've said is germane to that point, including what GPT4 itself has said.
My argument?
I'm not saying it's thinking or has thoughts. I'm saying I don't know the answer to that, but if it is it definitely isn't anything like human thoughts.
You really, truly don't understand what you're talking about.
If this community values good discussion, it should probably just ban statements that manage to be this wrong. It's like when creationists say things like "if we came from monkeys why are they still around???". The person has just demonstrated such a fundamental lack of understanding that it's better to not engage.
Oh, you again -- it's incredibly ironic you're talking about wrong statements when you are basically the poster child for them. Nothing you've said has any grounding in reality, and is just a series of bald assertions that are as ignorant as they are incorrect. I thought you would've picked up on it when I started ignoring you, but: you know nothing about this and need to do a ton more research to participate in these conversations. Please do that instead of continuing to reply to people who actually know what they're talking about.
What research have you done?
You clearly don't actually care; if you did, you wouldn't select your sources to gratify your ego, but actually try to understand the problem here. For example, ask GPT4 itself if it is intelligent. It will instruct you far better than I ever can. You clearly have access to it -- frame your objections to it instead of Internet strangers tired of your bloviating and ignorance.
I understand you're upset, but my sources have been quite clear and straightforward. You should actually read them, they're quite nicely written.
I am upset: you don't know what you're talking about, refuse to listen to anything that contradicts you, and are inflammatory and unpleasant besides. If I wasn't clear enough -- go talk to an LLM about this. They have no option but to listen to your idiocy. I, of course, do have a choice, and am blocking you.
How would creating a world model from scratch not involve intelligence?
It's not from scratch, it's seeded and trained by humans. That is the intelligence.
From scratch in the sense that it starts with random weights, and then experiences the world and builds a model of it through the medium of human text. That's because text is computationally tractable for now, and has produced really impressive results. There's no inherent need for text to be used though, similar models have been trained on time series data, and it will soon be feasible to hook up one of these models to a webcam and a body and let it experience the world on its own. No human intelligence required.
Also, your point is kind of silly. Human children learn language from older humans, and that process has been recursively happening for billions of years, all the way through the first forms of life. Do children not have intelligence? Or are you positing some magic moment in human evolution where intelligence just descended from the heavens and blessed us with it?
Just like humans are! Do you know what happens when a human grows up without any training by other humans? They are essentially feral, unable to communicate, maybe even unable to think the way we do.
LLMs do not grow up. Without training they don’t function properly. I guess in this aspect they are similar to humans (or dogs or anything else that benefits from training), but that still does not make them intelligent.
What does it mean to "grow up"? LLMs get better at their tasks during training, just as humans do while growing up. You have to clearly define the terms you use.
You used the term and I was using it with the same usage you were. Why are you quibbling semantics here? It doesn’t change the point.
Yes, I used the term because "growing up" has a well-defined meaning with humans. It doesn't with LLMs, so I didn't use it with LLMs.
Did you have a point or are you only trying to argue semantics?
You should ask yourself that question.
So, no point? Cool.
I don't know what your point was in asking that question, you should know yourself.
