| > No refusal fires, no warning appears — the probability just moves I don't really understand why this type of pattern occurs, where the later words in a sentence don't properly connect to the earlier ones in AI-generated text. "The probability just moves" should, in fluent English, be something like "the model just selects a different word". And "no warning appears" shouldn't be in the sentence at all, as it adds nothing that couldn't be better said by "the model neither refuses nor equivocates". I wish I better understood how ingesting and averaging large amounts of text produced such a success in building syntactically-valid clauses and such a failure in building semantically-sensible ones. These LLM sentences are junk food, high in caloric word count and devoid of the nutrition of meaning. |

While it wasn't a great signal it was a decent one since no one bothered with garbage posts to phrase it nicely like that. Now any old prompt can become what at first glance is something someone spent time thinking about even if it is just slop made to look nice. This doesn't mean anything AI is bad, just that if AI made it look nice that isn't inductive of care in the underlying content. | | |

The insult arises from the fact that "'real' AI" sounds nothing particularly like anyone, because it isn't any one: if it had eyes there would be nothing happening behind them. This is why it keeps driving people insane: there are cognitive vulnerabilities here which, for most humans, have until a couple of years ago been about as realistic to need to worry about as a literal alien invasion. To a human, being compared with something which can only pretend to humanity - and that not at all well! - is an insult. It should be an insult, too. Anyone is welcome to try and fail to convince me otherwise. | | |

| It's really simple. RL on human evaluators selects for this kind of 'rhetorical structure with nonsensical content'. Train on a thousand tasks with a thousand human evaluators and you have trained a thousand times on 'affect a human' and only once on any given task. By necessity, you will get outputs that make lots of sense in the space of general patterns that affect people, but don't in the object level reality of what's actually being said. The model has been trained 1000x more on the former. Put another way: the framing is hyper-sensical while the content is gibberish. This is a very reliable tell for AI generated content (well, highly RL'd content, anyway). |

| Neural networks are universal approximators. The function being approximated in an LLM is the mental process required to write like a human. Thinking of it as an averaging devoid of meaning is not really correct. |
| |
| ▲ | Terr_ 13 hours ago | parent | next [-] | | > The function being approximated in an LLM is the mental process required to write like a human. Quibble: That can be read as "it's approximating the process humans use to make data", which I think is a bit reaching compared to "it's approximating the data humans emit... using its own process which might turn out to be extremely alien." | | |
| ▲ | TeMPOraL 13 hours ago | parent [-] | | Good point. Then again, whatever process we're using, evolution found it in the solution space, using even more constrained search than we did, in that every intermediary step had to be non-negative on the margin in terms of organism survival. Yet find it did, so one has to wonder: if it was so easy for a blind, greedy optimizer to random-walk into human intelligence, perhaps there are attractors in this solution space. If that's the case, then LLMs may be approximating more than merely outcomes - perhaps the process, too. | | |
| ▲ | jayd16 13 hours ago | parent | next [-] | | Its fuzzier than that. Something can be detrimental and survive as long as its not too detrimental. Plus there is the evolving meta that moves the goal posts constantly. Then there's the billions of years of compute... | |
| ▲ | wavemode 12 hours ago | parent | prev | next [-] | | An easy counterargument is that - there are millions of species and an uncountable number of organisms on Earth, yet humans are the only known intelligent ones. (In fact high intelligence is the only trait humans have that no other organism has.) That could perhaps indicate that intelligence is a bit harder to "find" than you're claiming. | |

| ▲ | thrownthatway 13 hours ago | parent | prev [-] | | > if it was so easy That’s one giant leap you got there. That the probably that intelligent life exists in the universe is 1, says nothing about that ease, or otherwise, with which it came about.

| ▲ | Borealid 14 hours ago | parent | prev | next [-] | | I don't think of it as "devoid of meaning". It's just curious to me that minimizing a loss function somehow results in sentences that look right but still... aren't. Like the one I quoted. | | |
| ▲ | kybernetikos 13 hours ago | parent [-] | | A human in school might try to minimise the difference between their grades and the best possible grades. If they're a poor student they might start using more advanced vocabulary, sometimes with an inadequate grasp of when it is appropriate. Because the training process of LLMs is so thoroughly mathematicalised, it feels very different from the world of humans, but in many ways it's just a model of the same kinds of things we're used to. |

| ▲ | fyredge 13 hours ago | parent | prev | next [-] | | > Thinking of it as an averaging devoid of meaning is not really correct. To me, this sentence contradicts the sentence before it. What would you say neural networks are then? Conscious? | | |
| ▲ | kybernetikos 13 hours ago | parent [-] | | They are a mathematical function that has been found during a search that was designed to find functions that produce the same output as conscious beings writing meaningful works. | | |
| ▲ | fyredge 13 hours ago | parent [-] | | Agreed, and to that point, the way to produce such outputs is to absorb a large corpus of words and find the most likely prediction that mimics the written language. By virtue of the sheer amount of text it learns from, would you say that the output tends to find the average response based on the text provided? After all, "over fitting" is a well known concept that is avoided as a principle by ML researchers. What else could be the case? | | |
| ▲ | kybernetikos 7 hours ago | parent [-] | | I think 'average' is creating a bad intuition here. In order to accurately predict the next word in a human generated text, you need a model of the big picture of what is being said. You need a model of what is real and what is not real. You need a model of what it's like to be a human. The number of possible texts is enormous which means that it's not like you can say "There are lots of texts that start with the same 50 tokens, I'll average the 51st token that appears in them to work out what I should generate". The subspace of human generated texts in the space of all possible texts is extremely sparse, and 'averaging' isn't the best way to think of the process. |

| |
| ▲ | coppsilgold 12 hours ago | parent [-] | | This is more or less what happens. These models are tuned with reinforcement learning from human feedback (RLHF). Humans give them feedback that this type of language is good. The notorious "it's not X, it's Y" pattern is somewhat rare from actual humans, but it's catnip for the humans providing the feedback. |

Because AI is not intelligent, it doesn't "know" what it previously output even a token ago. People keep saying this, but it's quite literally fancy autocorrect. LLMs traverse optimized paths along multi-dimensional manifolds and trick our wrinkly grey matter into thinking we're being talked to. Super powerful and very fun to work with, but assuming a ghost in the shell would be illusory. |

To you it might be obvious our brains are different from a network of weights being reconfigured as new information comes in; to me it's not so clear how they differ. And I do not feel I know the meaning of the word "know" clearly enough to establish whether something that can emit fluent text about a topic is somehow excluded from "knowing" about it through its means of construction. | |

Every time you recall a memory it is modified, every time you verbalise a memory it is modified even more so. Eye-witness accounts are notoriously unreliable, people who witness the same events can have shockingly differing versions. Memories are modified when new information, real or fabricated, is added. It’s entirely possible to convince people to recall events that never occurred. Which of your memories are you certain are of real occurrences, or memories of dreams? | | |

Similarly, the repair manual cannot reason about novel circumstances, or apply logic to fill in gaps. LLMs quite obviously can - even if you have to reword that sentence slightly. |

| ▲ | dvt 14 hours ago | parent | next [-] | | > If all the training data contains semantically-meaningful sentences it should be possible to build a network optimized for generating semantically-meaningful sentence primarily/only. Not necessarily. You can check this yourself by building a very simple Markov Chain. You can then use the weights generated by feeding it Moby Dick or whatever, and this gap will be way more obvious. Generated sentences will be "grammatically" correct, but semantically often very wrong. Clearly LLMs are way more sophisticated than a home-made Markov Chain, but I think it's helpful to see the probabilities kind of "leak through." | | |
| ▲ | WarmWash 13 hours ago | parent [-] | | But there is a very good chance that is what intelligence is. Nobody knows what they are saying either, the brain is just (some form) of a neural net that produces output which we claim as our own. In fact most people go their entire life without noticing this. The words I am typing right now are just as mysterious to me as the words that pop on screen when an LLM is outputting. I feel confident enough to disregard duelists (people who believe in brain magic), that it only leaves a neural net architecture as the explanation for intelligence, and the only two tools that that neural net can have is deterministic and random processes. The same ingredients that all software/hardware has to work with. | | |

| ▲ | WarmWash 13 hours ago | parent [-] | | Again, unless you are a dualist, we can put comfortable bounds on what the brain is. We know it's made from neurons linked together. We know it uses mediators and signals. We know it converts inputs to outputs. We know it can only be using deterministic and random processes. We don't know the architecture or algorithms, but we know it abides by physics and through that know it also abides by computational theory. | | |

It's a difficult thing to produce a body of text that conveys a particular meaning, even for simple concepts, especially if you're seeking brevity. The editing process is not in the training set, so we're hoping to replicate it simply by looking at the final output. How effectively do you suppose model training differentiates between low quality verbiage and high quality prose?
