It's funny how people always quickly point out that an LLM wasn't made for this, and then continue to shill it for use cases it wasn't made for either (The "intelligence" part of AI, for starters)

    LLM wasnโ€™t made for this

    There's a thought experiment that challenges the concept of cognition, called The Chinese Room. What it essentially postulates is a conversation between two people, one of whom is speaking Chinese and getting responses in Chinese. And the first speaker wonders "Does my conversation partner really understand what I'm saying or am I just getting elaborate stock answers from a big library of pre-defined replies?"

    The LLM is literally a Chinese Room. And one way we can know this is through these interactions. The machine isn't analyzing the fundamental meaning of what I'm saying, it is simply mapping the words I've input onto a big catalog of responses and giving me a standard output. In this case, the problem the machine is running into is a legacy meme about people miscounting the number of "r"s in the word Strawberry. So "2" is the stock response it knows via the meme reference, even though a much simpler and dumber machine that was designed to handle this basic input question could have come up with the answer faster and more accurately.

    When you hear people complain about how the LLM "wasn't made for this", what they're really complaining about is their own shitty methodology. They build a glorified card catalog. A device that can only take inputs, feed them through a massive library of responses, and sift out the highest probability answer without actually knowing what the inputs or outputs signify cognitively.

    Even if you want to argue that having a natural language search engine is useful (damn, wish we had a tool that did exactly this back in August of 1996, amirite?), the implementation of the current iteration of these tools is dogshit because the developers did a dogshit job of sanitizing and rationalizing their library of data. Also, incidentally, why Deepseek was running laps around OpenAI and Gemini as of last year.

    Imagine asking a librarian "What was happening in Los Angeles in the Summer of 1989?" and that person fetching you back a stack of history textbooks, a stack of Sci-Fi screenplays, a stack of regional newspapers, and a stack of Iron-Man comic books all given equal weight? Imagine hearing the plot of the Terminator and Escape from LA intercut with local elections and the Loma Prieta earthquake.

    That's modern LLMs in a nutshell.

    You've missed something about the Chinese Room. The solution to the Chinese Room riddle is that it is not the person in the room but rather the room itself that is communicating with you. The fact that there's a person there is irrelevant, and they could be replaced with a speaker or computer terminal.

    Put differently, it's not an indictment of LLMs that they are merely Chinese Rooms, but rather one should be impressed that the Chinese Room is so capable despite being a completely deterministic machine.

    If one day we discover that the human brain works on much simpler principles than we once thought, would that make humans any less valuable? It should be deeply troubling to us that LLMs can do so much while the mathematics behind them are so simple. Arguments that because LLMs are just scaled-up autocomplete they surely can't be very good at anything are not comforting to me at all.

    This. I often see people shitting on AI as "fancy autocomplete" or joking about how they get basic things incorrect like this post but completely discount how incredibly fucking capable they are in every domain that actually matters. That's what we should be worried about... what does it matter that it doesn't "work the same" if it still accomplishes the vast majority of the same things? The fact that we can get something that even approximates logic and reasoning ability from a deterministic system is terrifying on implications alone.

    Why doesn't the LLM know to write (and run) a program to calculate the number of characters?

    I feel like I'm missing something fundamental.

    You didn't get good answers so I'll explain.

    First, an LLM can easily write a program to calculate the number of rs. If you ask an LLM to do this, you will get the code back.

    But the website ChatGPT.com has no way of executing this code, even if it was generated.

    The second explanation is how LLMs work. They work on the word (technically token, but think word) level. They don't see letters. The AI behind it literally can only see words. The way it generates output is it starts typing words, and then guesses what word is most likely to come next. So it literally does not know how many rs are in strawberry. The impressive part is how good this "guessing what word comes next" is at answering more complex questions.

    The LLM isn't aware of its own limitations in this regard. The specific problem of getting an LLM to know what characters a token comprises has not been the focus of training. It's a totally different kind of error than other hallucinations, it's almost entirely orthogonal, but other hallucinations are much more important to solve, whereas being able to count the number of letters in a word or add numbers together is not very important, since as you point out, there are already programs that can do that.

    At the moment, you can compare this perhaps to the Paris in the the Spring illusion. Why don't people know to double-check the number of 'the's in a sentence? They could just use their fingers to block out adjacent words and read each word in isolation. They must be idiots and we shouldn't trust humans in any domain.

    I'd be more impressed if the room could tell me how many "r"s are in Strawberry inside five minutes.

    You might just love Blind Sight. Here, they're trying to decide if an alien life form is sentient or a Chinese Room:

    "Tell me more about your cousins," Rorschach sent.

    "Our cousins lie about the family tree," Sascha replied, "with nieces and nephews and Neandertals. We do not like annoying cousins."

    "We'd like to know about this tree."

    Sascha muted the channel and gave us a look that said Could it be any more obvious? "It couldn't have parsed that. There were three linguistic ambiguities in there. It just ignored them."

    "Well, it asked for clarification," Bates pointed out.

    "It asked a follow-up question. Different thing entirely."

    Bates was still out of the loop. Szpindel was starting to get it, though.. .

    Blindsight is such a great novel. It has not one, not two but three great sci-fi concepts rolled into one book.

    One is artificial intelligence (the ship's captain is an AI), the second is alien life so vastly different it appears incomprehensible to human minds. And last but not least, and the most wild, vampires as a evolutionary branch of humanity that died out and has been recreated in the future.

    Also, the extremely post-cyberpunk posthumans, and each member of the crew is a different extremely capable kind of fucked up model of what we might become, with the protagonist personifying the genre of horror that it is, while still being occasionally hilarious.

    Despite being fundamentally a cosmic horror novel, and relentlessly math-in-the-back-of-the-book hard scifi it does what all the best cyberpunk does and shamelessly flirts with the supernatural at every opportunity. The sequel doubles down on this, and while not quite as good overall (still exceptionally good, but harder to follow) each of the characters explores a novel and sweet+sad+horrifying kind of love.

    My a favorite part of the vampire thing is how they died out. Turns out vampires start seizing when trying to visually process 90ยฐ angles, and humans love building shit like that (not to mention a cross is littered with them). It's so mundane an extinction I'd almost believe it.

  • That's a very long answer to my snarky little comment :) I appreciate it though. Personally, I find LLMs interesting and I've spent quite a while playing with them. But after all they are like you described, an interconnected catalogue of random stuff, with some hallucinations to fill the gaps. They are NOT a reliable source of information or general knowledge or even safe to use as an "assistant". The marketing of LLMs as being fit for such purposes is the problem. Humans tend to turn off their brains and to blindly trust technology, and the tech companies are encouraging them to do so by making false promises.

    a much simpler and dumber machine that was designed to handle this basic input question could have come up with the answer faster and more accurately

    The human approach could be to write a (python) program to count the number of characters precisely.

    When people refer to agents, is this what they are supposed to be doing? Is it done in a generic fashion or will it fall over with complexity?

    Imagine asking a librarian "What was happening in Los Angeles in the Summer of 1989?" and that person fetching you ... That's modern LLMs in a nutshell.

    I agree, but I think you're still being too generous to LLMs. A librarian who fetched all those things would at least understand the question. An LLM is just trying to generate words that might logically follow the words you used.

    IMO, one of the key ideas with the Chinese Room is that there's an assumption that the computer / book in the Chinese Room experiment has infinite capacity in some way. So, no matter what symbols are passed to it, it can come up with an appropriate response. But, obviously, while LLMs are incredibly huge, they can never be infinite. As a result, they can often be "fooled" when they're given input that semantically similar to a meme, joke or logic puzzle. The vast majority of the training data that matches the input is the meme, or joke, or logic puzzle. LLMs can't reason so they can't distinguish between "this is just a rephrasing of that meme" and "this is similar to that meme but distinct in an important way".

    There are different types of Artificial intelligences. Counter-Strike 1.6 bots, by definition, were AI. They even used deep learning to figure out new maps.

    No. Artificial Intelligence has to be imitating intelligent behavior - such as the ghosts imitating how, ostensibly, a ghost trapped in a maze and hungry for yellow circular flesh would behave, and how CS1.6 bots imitate the behavior of intelligent players. They artificially reproduce intelligent behavior.

    Which means LLMs are very much AI. They are not, however, AGI.

    Hey now, that's unfair and queerphobic.

    These models are from 1950, with juiced up data sets. Alan turing personally sid a lot of work on them, before he cracked the math and figured out they were shit and would always be shit.

    Adding weights doesn't make it a fundamentally different algorithm.

    We have hit a wall where these programs have combed over the totality of the internet and all available datasets and texts in existence.

    There isn't any more training data to improve with, and these programs have stated polluting the internet with bad data that will make them even dumber and incorrect in the long run.

    We're done here until there's a fundamentally new approach that isn't repetitive training.

    Transformers were pretty novel in 2017, I don't know if they were really around before that.

    Anyway, I'm doubtful that a larger corpus is what's needed at this point. (Though that said, there's a lot more text remaining in instant messager chat logs like discord that probably have yet to be integrated into LLMs. Not sure.) I'm also doubtful that scaling up is going to keep working, but it wouldn't surprise that much me if it does keep working for a long while. My guess is that there's some small tweaks to be discovered that really improve things a lot but still basically like like repetitive training as you put it. Who can really say though.
