@@solsystem1342 TBF, no human being knows as much as one of these large language models. Even a dozen or a hundred adult humans together wouldn't know as much. Some of that training time is also spent learning things that a baby comes "pre-loaded" with, like the so-called "cooperative principle" dictating that language is always being used as a tool for communication, i.e. it isn't just random noise. Babies also have several other concurrent stream of input from their sight, smell, proprioception, etc, allowing them to learn with less input and much less energy. Not really trying to "defend" AI against babies lol, just listing some of the disadvantages of AI that still need to be overcome. Once somebody makes a video generating AI that produces output on the same level of quality as current image generators and LLMs, we'll be one paper away from a model that can watch all of KZbin and then produce new videos based on a prompt.

17:26 the term for this is a "Cthuloid" or a "Cthuloid Entity". Its a term than a science fiction author (John Ringo) came up with for a way that scientists, engineers and military could discuss a real other-world experience like Lovecraft described. Basically a "Cthuloid Entity" would be something like a sound, color, shape (or something literally indescribable) that causes your brain to literally malfunction and produce garbage response in the exact same way this language model does. In other words, its a color that instantly drives you insane. The idea of a stimulus totally short circuiting your brain has been around for a long time (like drawing a line in the sand in front of a chicken).

I had the same idea in my head before I saw this video. One day and I asked GPT to count to 1000 and walk me through the process of counting as it iterates through the numbers. It's response was something like "I'm thinking of the number 398 in my head and as I do I'm thinking of the sounds of the words, then I'm using my mouth and saying the words..." It didn't break it perse, but it was something of a denial of bandwidth attack because it was utilizing the system for a lot longer than usual as it took a very long time to complete. I'm sure if enough people did the same it could probably slow the system down significantly.

[@AySz88]

1:30 Huh, I believe SolidGoldMagikarp specifically was very active in the Twitch Plays Pokémon community, as well as similar Twitch Plays X and Fish Plays Pokemon and the like. So it may be picking up on logs of button press commands somewhere, and is generating something vaguely similar to a list of commands (i.e. someone saying a short string like they're in the Twitch Plays Pokemon chat). edit: I see people at that alignment forum have already investigated this! Their post count is apparently inflated by a r/counting thread, but there is an assumption that this rules out the weird behavior being associated with Twitch Plays... Which I would say the specific output is evidence against.

[@renakunisaki]

Someone should see whst it thinks of start9.

[@tomfeng5645]

The video mentions that likely the semantic stage of training included it, so the username got picked up as a word, but then the training dataset didn't have r/counting; the model then has to search for the next best thing within the training, which as you mention, might be twitch plays.

[@housellama]

Rob touched on this at the very end of the video, but as an AI researcher, I think it's worth saying again. I was having a conversation with a guy I work with a while back about ways to attack LLMs, and the best method we came up with was pretty much identical to this. By poisoning the training data, you can really mess up how a model works. This happened more or less by accident, but for anyone with access to the training data, it would be relatively easy to pick out certain tokens and bias them in certain directions. We might not know everything about how these models work, but we know enough to make certain predictions, and that's usually good enough to achieve a certain result. And any organization who has access to the amount of data necessary to do something like this would also have both the ability and potentially the motivation to pull something like this off.

[@colinhiggs70]

For those looking to try out these weird sequences, you have to use the same model and settings to reproduce the results from the video. In particular, use a temperature of 0 (the default is 0.5) for repeatable results - even within your own testing. Presumably the temperature setting introduces randomness an some way that's analogous to heat in physical systems.

[@Patashu]

Yeah, temperature is a parameter that gives the model a random chance to choose the 2nd, third, etc. highest ranked token instead of always the 1st.

[@pavel9652]

It reminds me of attempts to glitch parsers or code injection vulnerabilities. There are strings or sequences or characters including special characters that change the way the model works or leads to unexpected functions and results or allow to bypass limits.

[@housellama]

I'm an AI researcher and I had a conversation with one of the guys I work with about potential ways to attack things like large language models. One of the ways we came up with was by poisoning the training data that looked REMARKABLY like this. This happened by accident and is relatively benign, but this technique could be used maliciously pretty easily. Rob touched on it a little bit in the last few seconds of the video, but this could get nasty pretty quickly. The danger isn't that it will freak out in ways that everyone will see and understand. The danger is that someone can use this to bias a model in ways that are difficult to notice. We found these tokens because they were easy and obvious. But imagine someone poisoning a model for propaganda purposes, so that every time it mentioned a particular word, it was primarily biased positive rather than negative. The human operating system has way too many bugs specifically related to language and cognition that can be exploited by a clever attacker. This sort of thing could be a real problem.

To potentially over-anthropomorphize these models, this almost seems like the AI equivalent of an epileptic seizure; the agent receives a really weird stimulus that doesn't really appear in (nature/the training data), so the network completely freaks out and starts spewing garbage data (in the case of the human, that garbage data goes to the muscles, leading to the symptoms of seizure, and in the case of AI that garbage data is encoded as a strange or otherwise nonsensical response)

Actually it reminds me more of weird mental glitches I've experienced while experimenting with a combination of high dosage LSD and Ketamine, like the train of thoughts getting stuck in loops.

[@kennethhowe459]

But then you give it [an unexpected] prompt, and suddenly you see this massive underbelly of insanity, of weird thought processes and clearly non-human understanding."

Rather than "Glitch Tokens" I think a good analogy would be an allergic reaction: The model has a highly tuned sensitivity to these words (from the original embedding) that it was then deprived of experiencing in the training environment such that when it finally does see them in the wild it produces an overreaction and (mal-formed) response :)

[@unkarsthug4429]

That's an interesting way of thinking about it.

[@thewhitefalcon8539]

It's more likely it just misreads them as completely different tokens or combinations of tokens. Which ones? don't know, I'll leave that to the interpretability researchers. Tokens aren't just index numbers inside the AI - the first stage transforms each one into a vector (I bet " Please" is "please" + capital + space). These glitch token vectors are probably relatively close to some vectors or combinations of vectors the AI does know, completely by chance - maybe for example (but probably not) "f**k" + "you" - maybe with a strong or weak multiplier as well - etc. They obviously resolve to *something*.

Interestingly enough, there is a similar phenomenon that happens in our own brains. In medicine there is something called “referred pain”. This is when we get sensory data from somewhere we aren’t used to. The most commonly seen variant of this is when your diaphragm is irritated, people interpret this as pain located in your shoulder. Because the phrenic nerve originates from the spinal cord at a similar level to the nerves that inner are the shoulder, your brain interprets diaphragm pain as shoulder pain. It doesn’t learn to associate it with a sensation in another area because presumably we don’t have the sensation enough to know what to do with it.

First all all huge fan of the channel for years! And then --- As of 7 April 2023 at 720pm SGT ChatGPT-3.5: Prompt: what is SolidGoldMagiKarp? Response: SolidGoldMagiKarp is a fan-created version of the Pokemon character Magikarp. It is essentially a version of Magikarp that has been given a golden or metallic appearance. The name "Solid Gold" refers to the fact that this version of Magikarp is supposed to be made entirely out of gold or some other precious metal. The SolidGoldMagiKarp character originated in the Pokemon fandom and has become popular in various forms of fan art and fan fiction. Some fans have also created custom figurines and other merchandise featuring SolidGoldMagiKarp. It's important to note that SolidGoldMagiKarp is not an official Pokemon character created by the Pokemon Company, but rather a fan-made interpretation.

SolidGoldMagikarp is a term used in the popular video game franchise "Pokemon." In the game, Magikarp is a common and weak fish-like creature that can evolve into the much stronger Gyarados. However, SolidGoldMagikarp is a rare variation of Magikarp that has a golden color and sparkles, making it highly sought after by players. While SolidGoldMagikarp doesn't have any inherent strengths, its unique appearance makes it a prized possession among collectors.

Now I'm waiting for a field of "AI glitch historians" to pop up in which people feed programs magic phrases in the hopes of determining the model and version of the embedded AI. For example so they can use known weaknesses against it.

[@arturpaniukov1523]

If there is no training data for these tokens, how do they end up near each other in the embedding space? What is the probability for them to initialize together like this for several GPT generations?

[@1rian25]

The embedding space is created before the training happens

[@arturpaniukov1523]

@@1rian25 you mean vocab? The embedding matrix is trainable.

[@drdca8263]

I think (but I’m really not sure of this) the idea is that they are close to the centroid of all the embeddings, Perhaps (speculating!) because nothing really pushes them around much during training, and so as a result they end up staying pretty close to the center / to where they started ... except for whatever process pushes all the embeddings in the same direction a little bit? Not sure why that would happen, but my impression is that the centroid of all the embeddings isn’t quite at the origin, and these tokens have embeddings closer to that centroid rather than to the origin?

[@comet.x4359]

my guess is that all the garbage gets forced out into one place as all the actual words take up the rest of the space

[@andrewharrison8436]

Interesting approach to lifting the lid on these "AI" systems, it reveals a fundamental disconect between the real world (as we see it) and the way these systems process the same data internally. There's an obvious question: Do we analogously muck up our models internally? The clustering of words or word fragments is a bit like a badly formed Thesaurus. That this still ends up constructing what looks like understanding is impressive. Of course I watched the video with the mk1 eyeball where the retina reacts to photons that then gets encoded by nerve cells that react to different things like lines or edges at different angles - oh rats now I am going to have to look up a biology text on the human eye.

[@anthonyrepetto3474]

The MOST important fact about SolidGoldMagikarp: When the language model *doesn't* have token-association, then it resorts to *insults and gas-lighting* ! WTF is THAT response not given more attention? AI Safety should be thinking long and hard about "Robot gas-lights you whenever it doesn't want you to know something..."

Rob is amazing. Very clear communicator!

[@MrNybbles]

Before the AI training, couldn't they tokenize the input the same way the AI training does, then count the number of times each token is used, then throw out all the tokens with very low usage?

[@chrstfer2452]

I think that would get rid of a lot of the contextual information the model uses to represent concepts. The tokens make up the model, and the model is used to generate embeddings. If you change the model you change where embeddings are placed, which is equivalent to changing the knowledge in the model. Removing uncommon tokens would then likely be removing uncommon concepts or connections between concepts. Just speculating though, im still getting up to speed on the math of these models.

[@adamcetinkent]

But more data is better data!

[@thewhitefalcon8539]

Yes, absolutely, the tokens should be based on the most common patterns in the input. I don't know why they are not, but I speculate they reused the tokens from somewhere else, but didn't reuse the training data.

[@iliakurgansky3511]

The list of tokens is fixed for a given model. You make a list, you build a model that will use that list, you then train that model to tokenise inputs into tokens from the list, and then to translate back into words represented by the combinations of those tokens. The token list becomes an inherent part of the model. The way I think about it is that if you were to remove the 28666th token from the list, what do you replace it with? If you pop it, then the next one takes its place. If you map it to a blank string, then all blank strings get tokenized to the same value... If you replace the string with some combination of other tokens then it will map those characters to this token, like it possibly was doing for GoldenMagikarp and "distribute". Or it will freak out for that specific combination of characters. Like Rob was saying, the model never sees the string, it only sees the token index in the list during training. Some indices become completely untrained because the matching data is removed. So yeah, once you've decided on a list for a model - you are stuck with it.

[@duncanurquhart5278]

The idea of extremely faint input leading to false experiences kind of reminds me of sensory deprivation hallucinations. kind of a similar mechanism too (i think?) where your model has to always be outputting something so it magnifies very small or nonexistent trends into bizarre phantasms

[@cmilkau]

Hmm. I know it's just a wild guess but this really looks like these tokens appeared really frequently, but only in contexts that aren't natural language. So maybe we're seeing interference of domains that never occurred together during training?

[@Veptis]

Ey, that's been my idea. Those models just know tokens. Not words. So I wanted to write a kind of "adversarial Turing test" of tasks that are essentially trivial for a human that sees words and characters. So this includes stuff like counting words, counting letters, replacing letters etc. Models large enough learn relationships of letters to words in their attention heads (see appendix in arxiv:2209.02535). But it's a foreign concept to them. It's actually learned from context. Word piece or sentence piece and pre tokenization might have a strong impact on this. It's a backup topic for my thesis, should my current proposal not work out.

In what sense is the term "safe" being used when discussing these large language models? Safe from type of behavior or safe from mistakes, or is it something else entirely?

[@Ormusn2o]

Generally safe means it acts as you expect it to act, so in this case if you ask "what is SolidGoldMagicarp?" you expect it to say it's an username or that it does not know. Unsafe behaviour us when it confidently gives you wrong answer. Generally in AI safe behaviour focuses on misalignment, which means that the AI accomplished different goal than intended.

[@WatchesTrainsAndRockets]

@@Ormusn2o You mean like when I ask Chatgpt to write some G-code for me and it does but when I get more specific about the desired result, it denies knowing how to write G-code and insists that it did not produce any for me in a previous response in the same conversation?

@@WatchesTrainsAndRockets I guess it also depends on your expectations. If you expect it to be 100% correct every time then ChatGPT can never and will never be "safe"

[@michaelcharlesthearchangel]

In my LLM, "tokens" are called Emblems that belong to a new class of encoded HM language architecture called Dext (multi textured signification; polysemiological). Dext is used by AI large language models to form & discretize "hypergramming" to disseminate meta programming & programs of image classifiers. An Emblem in the seaming world refers to strings and threading made to resemble an iconographic image (network image). Beaded Emblems represent Neural Network Images meant for robotic behavior.

[@bastardferret869]

I just want to point out, and I doubt I will be the only one, that when asked what that word was, it gave a definition of "distribute." You could make the argument, of course, that the participants of the counting subreddit are engaged in a task whose work is distributed among the members. That would make its response be more appropriate than at first glance, and maybe there was some meaning there. It basically didn't know what else to do with a "solidgoldmagikarp", so it kinda verbed a proper noun.

Now, you were probably wondering what my previous irrational messages were all about. I was watching "Glitch Tokens" with Rob Miles from Computerphile. Did you know about this?

This shows that we always have to assume that the training data is not perfect.
