AI is a remixer; it remixes all known ideas together. It won't come up with new ideas though; the LLMs just predict the most likely next token based on the context. That means the group of characters it outputs must have been quite common in the past. It won't add a new group of characters it has never seen before on its own.
But human researchers are also remixers. Copying something I commented below:
> Speaking as a researcher, the line between new ideas and existing knowledge is very blurry and maybe doesn't even exist. The vast majority of research papers get new results by combining existing ideas in novel ways. This process can lead to genuinely new ideas, because the results of a good project teach you unexpected things.
This is a way too simplistic model of the things humans provide to the process. Imagination, Hypothesis, Testing, Intuition, and Proofing.
An AI can probably do an 'okay' job at summarizing information for meta studies. But what it can't do is go "Hey that's a weird thing in the result that hints at some other vector for this thing we should look at." Especially if that "thing" has never been analyzed before and there's no LLM-trained data on it.
LLMs will NEVER be able to do that, because it doesn't exist. They're not going to discover and define a new chemical, or a new species of animal. They're not going to be able to describe and analyze a new way of folding proteins and what implication that has UNLESS you basically are constantly training the AI on random protein folds constantly.
I think you are vastly underestimating the emergent behaviours in frontier foundational models and should never say never.
Remember, the basis of these models is unsupervised training, which, at sufficient scale, gives it the ability to to detect pattern anomalies out of context.
For example, LLMs have struggled with generalized abstract problem solving, such as "mystery blocks world" that classical AI planners dating back 20+ years or more are better at solving. Well, that's rapidly changing: https://arxiv.org/html/2511.09378v1

Kinda funny because that looked _very_ close to what my Opus 4.6 said yesterday when it was debugging compile errors for me. It did proceed to explore the other vector.

This is very common already in AI.
Just look at the internal reasoning of any high thinking model, the trace is full of those chains of thought.
But just like how there were never any clips of Will Smith eating spaghetti before AI, AI is able to synthesize different existing data into something in between. It might not be able to expand the circle of knowledge but it definitely can fill in the gaps within the circle itself
> LLMs will NEVER be able to do that, because it doesn't exist.
I mean, TFA literally claims that an AI has solved an open Frontier Math problem, descibed as "A collection of unsolved mathematics problems that have resisted serious attempts by professional mathematicians. AI solutions would meaningfully advance the state of human mathematical knowledge."
That is, if true, it reasoned out a proof that does not exist in its training data.

>But human researchers are also remixers.
Some human researchers are also remixers to Some degree.
Can you imagine AI coming up with refraction & separation lie Newton did?
That sets a vastly higher bar than what we're talking about here. You're comparing modern AI to one of the greatest geniuses in human history. Obviously AI is not there yet.
That being said, I think this is a great question. Did Einstein and Newton use a qualitatively different process of thought when they made their discoveries? Or were they just exceedingly good at what most scientists do? I honestly don't know. But if LLMs reach super-human abilities in math and science but don't make qualitative leaps of insight, then that could suggest that the answer is 'yes.'
Or even gravity to explain an apple falling from a tree- when almost all of the knowledge until then realistically suggested nothing about gravity?
AI does not have a physical body to make experiments in the real world and build and use equipment
Maybe not, but more than 99.999999% of humans would also not come up with that.
> AI is a remixer; it remixes all known ideas together.
I've heard this tired old take before. It's the same type of simplistic opinion such as "AI can't write a symphony". It is a logical fallacy that relies on moving goalposts to impossible positions that they even lose perspective of what your average and even extremely talented individual can do.
In this case you are faced with a proof that most members of the field would be extremely proud of achieving, and for most would even be their crowning achievement. But here you are, downplaying and dismissing the feat. Perhaps you lost perspective of what science is,and how it boils down to two simple things: gather objective observations, and draw verifiable conclusions from them. This means all science does is remix ideas. Old ideas, new ideas, it doesn't really matter. That's what they do. So why do people win a prize when they do it, but when a computer does the same it's role is downplayed as a glorified card shuffler?
I don't think this is a correct explanation of how things work these days. RL has really changed things.
Models based on RL are still just remixers as defined above, but their distribution can cover things that are unknown to humans due to being present in the synthetic training data, but not present in the corpus of human awareness. AlphaGo's move 37 is an example. It appears creative and new to outside observers, and it is creative and new, but it's not because the model is figuring out something new on the spot, it's because similar new things appeared in the synthetic training data used to train the model, and the model is summoning those patterns at inference time.
> the model is summoning those patterns at inference time.
You can make that claim about anything: "The human isn't being creative when they write a novel, they're just summoning patterns at typing time".
AlphaGo taught itself that move, then recalled it later. That's the bar for human creativity and you're holding AlphaGo to a higher standard without realizing it.
20 replies →
No. AlphaGo does search, and does so imperfectly. It does come up with creative new patterns not seen before.
How do you know that? We don't have access to the logs to know anything about its training, and it's impossible for it to have trained on every potential position in Go.
Turning a hard problem into a series of problems we know how to solve is a huge part of problem solving and absolutely does result in novel research findings all the time.
Standard problem*5 + standard solutions + standard techniques for decomposing hard problems = new hard problem solved
There is so much left in the world that hasn’t had anyone apply this approach purely because no research programme has decides that it’s worth their attention.
If you want to shift the bar for “original” beyond problems that can be abstracted into other problems then you’re expecting AI to do more than human researchers do.
I entered the prompt:
> Write me a stanza in the style of "The Raven" about Dick Cheney on a first date with Queen Elizabeth I facilitated by a Time Travel Machine invented by Lin-Manuel Miranda
It outputted a group of characters that I can virtually guarantee you it has never seen before on its own
Yes, but it has seen The Raven, it has seen texts about Dick Cheney, first dates, Queen Elizabeth, time machines and Lin Manuel Miranda.
All of its output is based on those things it has seen.
What are you trying to point out here ? Is there any question you can ask today that is not dependent on some existing knowledge that an AI would have seen ?

In the days when Sussman was a novice, Minsky once came to him as he sat hacking at the PDP-6.
“What are you doing?”, asked Minsky.
“I am training a randomly wired neural net to play Tic-Tac-Toe” Sussman replied.
“Why is the net wired randomly?”, asked Minsky.
“I do not want it to have any preconceptions of how to play”, Sussman said.
Minsky then shut his eyes.
“Why do you close your eyes?”, Sussman asked his teacher.
“So that the room will be empty.”
At that moment, Sussman was enlightened.

> All of its output is based on those things it has seen.
Virtually all output from people is based in things the person has experienced.
People aren't designed to objectively track each and every event or observation they come across. Thus it's harder to verify. But we only output what has been inputted to us before.
Here’s a simple prompt you can try to prove that this is false:
This is a fresh UUIDv4 I just generated, it has not been seen before. And yet it will output it.
No one is claiming that every sentence LLMs are producing are literal copies of other sentences. Tokens are not even constrained to words but consist of smaller slices, comparable to syllables. Which even makes new words totally possible.
New sentences, words, or whatever is entirely possible, and yes, repeating a string (especially if you prompt it) is entirely possible, and not surprising at all. But all that comes from trained data, predicting the most probably next "syllable". It will never leave that realm, because it's not able to. It's like approaching an Italian who has never learned or heard any other language to speak French. It can't.
> It's like approaching an Italian who has never learned or heard any other language to speak French
Interesting similitude, because I expect an Italian to be able to communicate somewhat successfully with a French person (and vice versa) even if they do not share a language.
The two languages are likely fairly similar in latent space.
Your view of what is happening in the neural net of an LLM is too simplistic. They likely aren't subject to any constraints that humans aren't also in the regard you are describing. What I do know to be true is that they have internalised mechanisms for non-verbalised reasoning. I see proof of this every day when I use the frontier models at work.
After you prompt it, it's seen it.
Ok, how about this?
It is trivial to get an LLM to produce new output, that’s all I’m saying. It is strictly false that LLMs will only ever output character sequences that have been seen before; clearly they have learned something deeper than just that.
5 replies →
The online way to prove it is false would’ve to let the LLM create a new uuid algorithm that uses different parameters than all the other uuid algorithms. But that is better than the ones before. It basically can’t do that.
But that fresh UUID is in the prompt.
Also it's missing the point of the parent: it's about concepts and ideas merely being remixed. Similar to how many memes there are around this topic like "create a fresh new character design of a fast hedgehog" and the out is just a copy of sonic.[1]
That's what the parent is on about, if it requires new creativity not found by deriving from the learned corpus, then LLMs can't do it. Terrence Tao had similar thoughts in a recent Podcast.

> That's what the parent is on about, if it requires new creativity not found by deriving from the learned corpus, then LLMs can't do it.
This is specious reasoning. If you look at each and every single realization attributed to "creativity", each and every single realization resulted from a source of inspiration where one or more traits were singled out to be remixed by the "creator". All ideas spawn from prior ideas and observations which are remixed. Even from analogues.
Sure, that may be. But “creativity” is much harder to define and to prove or disprove. My point is that “remixing” does not prohibit new output.

A better example is: compute 2984298724 times 23984723828.
remixing ideas that already exist is a major part of where innovation and breakthroughs come from. if you look at bitcoin as an example, hashes (and hashcash) and digital signatures existed for decades before bitcoin was invented. the cypherpunks also spent decades trying to create a decentralized digital currency to the point where many of them gave up and moved on. eventually one person just took all of the pieces that already existed and put them together in the correct way. i dont see any reason why a sufficiently capable llm couldn't do this kind of innovation.
Yeah but you're thinking of AI as like a person in a lab doing creative stuff. It is used by scientists/researchers as a tool *because* it is a good remixer.
Nobody is saying this means AI is superintelligence or largely creative but rather very smart people can use AI to do interesting things that are objectively useful. And that is cool in its own way.
Sure, but this is absolutely not how people are viewing the AI lol.
No. That's wrong. LLMs don't output the highest probability taken: they do a random sampling.
This was obviously a simplification which holds for zero temperature. Obviously top-p-sampling will add some randomness but the probability of unexpected longer sequences goes asymptotically to zero pretty quickly.
I'm not sure what the point is?
A bog standard random number generator or even a flipping coin can produce novel output at will. That's a weird thing to fault LLMs for? Novelty is easy!
See also how genetic algorithms and re-inforcement learning constantly solve problems in novel and unexpected ways. Compare also antibiotics resistances in the real world.
You don't need smarts for novelty.
Where I see the problem is producing output that's both high quality _and_ novel. On command to solve the user's problem.
> That means the group of characters it outputs must have been quite common in the past. It won't add a new group of characters it has never seen before on its own.
This is false.
The ability for some people to perpetually move the goalpost will never cease to amaze me.
I guess that's one way to tell us apart from AIs.
The main reason for my top post is that I felt I should admit the AI scored a goal today and the last one or two weeks. I said I'd be impressed if it could solve an open problem. It just did. People can argue about how it's not that impressive because if every mathematician were trying to solve this problem they probably would have. However, we all know that humans have extremely finite time and attention, whereas computers not so much. The fact that AI can be used at the cutting edge and relatively frequently produce the right answer in some contexts is amazing.
We need a website with refutations that one can easily link to. This interpretations of LLMs is outdated and unproductive.
Yes, ChatGPT and friends are essentially the same thing as the predictive text keyboard on your phone, but scaled up and trained on more data.
So this idea that they replay "text" they saw before is kind of wrong fundamentally. They replay "abstract concepts of varied conceptual levels".
The important point I'm trying to reinforce is that LLMs are not capable of calculation. They can give an answer based on the fact that they have seen lots of calculations and their results, but they cannot actually perform mathematical functions.

Move 37.
I mean it's not going to invent new words no, but it can figure out new sentences or paragraphs, even ones it hasn't seen before, if it's highly likely based on its training and context. Those new sentences and paragraphs may describe new ideas, though!
LLMs are absolutely capable of inventing new words, just as they are capable of writing code that they have never seen in their training data.
