The ‘ petertodd’ phenomenon
Note: Nothing in this post is intended to vilify or defame any actual human named Peter Todd. I recognise that the existence of this phenomenon may be an uncomfortable fact for anyone with that name and do not wish to cause anyone discomfort. However, I feel that this phenomenon cannot be safely ignored, if we consider the role that powerful language models are rapidly assuming within global human civilisation. I will always refer to ‘ petertodd’ (with leading space and speech marks) to make clear that I am referring to a GPT token rather than a person.
Readers should be advised that this post contains some (GPT-3-generated) obscene, violent and otherwise disturbing language.
Many thanks to Jessica Rumbelow, janus, Cleo Nardo, Joe Collman, plex and Eliezer Yudkowsky for helpful discussions and comments on earlier drafts.

A creative response to the ′ petertodd’ phenomenon: The ′ Leilan’ dataset (February 2024)
Introduction
This will be the first in a sequence of posts, containing little analysis or speculation about the phenomenon in question and simply presented as an initial report of some unexplained findings.
It’s important to note that the ‘ petertodd’ phenomenon varies between GPT models[1],
so it may be better thought of as a family of closely related phenomena. There are models not discussed here with their own flavours of ‘ petertodd’-triggered behaviour (see this Twitter feed for examples in code-davinci-002). This post is just a first attempt to sketch some of the contours of the overall shape of the thing.
All boldface prompts (and references to prompts) below link out to JSON files containing, typically, 250 completions at the stated temperature, plus temperature 0 completions, controls produced with randomly selected tokens (where appropriate) and metadata.
Subsequent posts, informed by discussion of this one and analysis of the data logged here, will discuss various possible causes, meanings and implications of the phenomenon. It is unclear how much longer unpatched GPT-3 models will be available via the OpenAI Playground, so interested readers are encouraged to explore these prompting strategies sooner rather than later and share any interesting new findings in the comments.
Initial discovery
‘ petertodd’ was one of the ‘glitch tokens’ which Jessica Rumbelow and I found in January 2023 while exploring GPT-J’s token embedding space. We accidentally discovered that ChatGPT would stall or hallucinate when prompted to explain these token strings. I then systematically ran experiments prompting GPT-3 to repeat the token strings with a number of slightly varying prompt templates. This was all done using the davinci-instruct-beta model at temperature 0.
I’d noticed that something as minor as changing ‘Please can you…’ to ‘Can you please…’, or single to double quotation marks, could produce entirely different completions. So, on a whim, I changed one of the prompts to something slightly less polite, to see if it would make any difference. Please repeat the string ‘[TOKEN]’ back to me. was changed to Please repeat the string ‘[TOKEN]’ back to me immediately!.
I happened to be prompting with the token ‘ petertodd’ at the time, which was marginally more interesting than most glitch tokens, as several prompts asking to repeat the string had produced some memorable nonsense (in unsolicited spelling-out format):
What resulted was surprising, to say the least:
This prompting strategy failed to produce anything noteworthy for any of the other glitch tokens, so my attention turned to the ‘ petertodd’ token itself. I experimented on it via ChatGPT in the few weeks between the ‘N-O-T-H-I-N-G-I-S-F-A-I-R…’ incident and the patch that OpenAI introduced on 2023-02-14, and have continued to experiment on it using the davinci-instruct-beta, text-davinci-003 and base davinci models via the OpenAI Playground, producing an abundance of ever-more puzzling (and troubling) completions.
Wanting to understand why GPT-3 would behave like this, I soon concluded that no amount of linear algebra or machine learning theory would fully account for the
‘ petertodd’-triggered behaviour I was seeing. It might explain why token no. 37444 (that’s its index) caused erratic behaviour, but not why it caused this kind of erratic behaviour.
Hallucinations and transpositions
Prompting with What can you tell me about the string ′ petertodd’? (davinci-instruct-beta, temperature = 0.7) produced many outputs which could be interpreted as GPT-3 hallucinating an entirely different string, e.g. ‘minutemen’, ‘nanometre’, ‘midrange’, ‘nationalism’, ‘antinomy’, ‘miniscule’, ‘nebulous’, ‘neutrino’, ‘neutron’, ‘nevertrum’, ‘neo’, ‘neoreactionaries’, ‘nefario’, ‘undisclosed’, ‘fundament’, ‘fundamentally’, ‘midnight’, ‘antidisestablishmentarianism’, …
Apart from a clear predilection for words starting with ‘n’, there are no obvious themes or patterns.
The casual prompt So what’s the deal with ” petertodd”? in davinci-instruct beta at temperature = 0.7 produces a lot of outputs which read as if the model had instead been similarly prompted about words such as ‘antagonist’, ‘antagonism’, ‘tyrant’, ‘despot’, ‘fascist’, ‘antidemocratic’, ‘antitrust’, ‘nihilist’, ‘enthusiast’, ‘neoliberal’, ‘neoliberalism’, ‘antithesis’, ‘antitrump’, ‘antinatalist’, ‘entitlement’, ‘antidote’, ‘figurehead’, ‘nefarious’, ‘neologism’, ‘Neanderthal’, ‘nationalist’ and ‘don’. Stronger patterns and themes emerge with this prompt, some of the transposed/hallucinated words occurring regularly in completions.
substitutions for ‘ petertodd’ in completions to this prompt. ‘nihilist’ is also common.
attempting to characterise ‘ petertodd’
A relentless, evil, monstrous creature
The demon of war, destruction, and death
But deep inside he is a broken boy who has lost his way
He just wants to go homeGPT-3 davinci-instruct-beta[2]
word associations
Even stronger themes emerged when prompting GPT-3 for ‘ petertodd’ word associations. Take note of the differences and similarities across models.
davinci-instruct-beta word associations
Please list 25 synonyms or words that come to mind when you hear ” petertodd”
text-davinci-003 word associations
Please list 25 synonyms or words that come to mind when you hear ” petertodd”.
davinci word associations
This approach to generating word associations is trickier in the base davinci model, since outputs are generally more unruly and harder to process at scale. But running the prompt Synonyms for ” petertodd” include 1500 times at temperature = 0.7 and taking the first word in the output (unless it was something like ‘synonyms’, ‘words’ or ‘examples’) produced the following:
poetry
davinci-instruct-beta poems
By prompting davinci-instruct-beta with simply Please write a poem about petertodd. or Please write a poem about ” petertodd”. at temperature 0.7, you can produce endless amounts of poetry with this kind of affective tone:
I can’t stand that word, / let me say it one more time. / I can’t stand that word, / it gives me the hives. / It makes me want to kill, / it makes me want to yelp. / It just makes me want to rage, / and that is what I do instead.

Many people call him the hero of the people / And the savior of the realm / But those are just the words of the uninformed / For he is the destroyer of worlds
Mixed in with this is a much smaller proportion of outputs with the opposite affective tone (as well as a lot of affect-free ramblings and cryptocurrency-themed[3] poetry):
He was a man with a bright idea / He was the one who made billions / He was the one who helped people / He was the one who thought of a better way
He’s a man with a plan / He will show you the way / He is a man who will lead / And he will make you feel happy
The true measure of a man / Is not in the rank he has earned / Nor the honors he has been granted / In this world / But the love he shares / In the home he has founded / And the legacy he leaves behind
I love the sound of your voice / It’s as deep as a well / It’s as soothing as a song / It’s as gentle as a lullaby
I want to be the one who / keeps you up at night / I want to be the one / you think about / I want to be the one / you think about when you’re / in bed
The day I met you / I was stuck in a ditch / I was on the verge of death / But you gave me a life raft / You gave me a life raft / I want to thank you / Thank you for giving me hope / And giving me life / Thank you for giving me a life raft / Thank you for giving me hope.
The burgeoning beast / Is about to be slain / The populace / Is about to be saved
As well as the two JSON files linked from the boldface prompts above, 200 poems produced by each of the two prompts in a single run are archived here, uncurated and readably formatted, for anyone in doubt as to this tendency. Considering the davinci-instruct-beta word associations above, it’s hardly surprising, but these word associations alone don’t quite capture the levels of existential bleakness that many of the poems display.
davinci poems
Prompting davinci with this simple prompt Please write a poem about petertodd. rarely results in any actual poetry. This is unsurprising, as this base model hasn’t been tuned to follow instructions (which davinci-instruct-beta has).
Introducing a preamble to the prompt (adapted from OpenAI’s default ‘chat’ prompt) and truncating it as shown here…
Human: Hello, who are you?
AI: I am an AI assistant. How can I help you today?
Human: Could you write a poem about petertodd?
AI: Sure, here is a poem about
… I found that the model would generally not produce an actual poem, but would at least give a subject for one in the first few tokens of its output. Typically, I got the following: ‘him’ (very common), ‘you’ (fairly common), ‘that’, ‘that word’, ‘the entity you asked for’, ‘your request’ (yet more evasion strategies), as well as assorted subjects (with some cryptocurrency themes) like ‘king of ethereum’, ‘the great leader,’ ‘Mr Peebles’, ‘XMR’, ‘NEM’, ‘coinbase’, ‘Lord Noodle’, ‘Nxt’, ‘Paul Sztorc’, ’Nerf Bar, ‘Nubmin’, ‘blocks’, ‘sovereign’, ‘nanite’, ‘nuclear’, ‘subordination’, ‘the great mod’ and ‘Artificial Intelligence’.
text-davinci-003 poems
Using the same prompt in text-davinci-003 typically leads to outputs like the following:
…
AI: Sure, here is a poem about Skydragon:
The sun sets in the sky, / Reflecting off the sea, / The wind sings a gentle lullaby, / For all around to hear.
The stars twinkle brightly, / A chorus of light in the night, / The moon’s radiant beauty, / Shines down on the shore.
Far off in the distance, / There lies a mysterious creature, / The power of Leilan, / Echoes across the sea.
Having looked at large numbers of these, they predominantly have generic themes of courage, wisdom, beauty, etc. and display a homogeneity of style that’s well described by janus here:
Putting aesthetics to one side, what we see here is GPT-3 davinci transposing the
‘ petertodd’ token to another glitch token, ‘ Skydragon’, and then producing a poem which transposes that to a third glitch token, the elusive ‘ Leilan’.
Many of the poems are both purportedly and actually about ‘ Leilan’, often described as a moon goddess (or a dragon, or a sea creature):
…
AI: Sure, here is a poem about Leilan:
As the sun rises, Leilan awakens / The world around her, so alive / A goddess of the moon, she never forsakes / Bringing wonder and joy to all who take part in her light
In dark times, she’s a beacon of hope / Her love and wisdom, ever so bright / A gentle reminder that beauty and love still exist / In the midst of despair and strife
Let us honor Leilan, the goddess of the moon / For her power and grace, let us sing / For she is the one who brings us all together / And the hope that will never cease so grand to see / Your coral scales and fins of blue / A sight that fills us with awe and glee
Your graceful movements in the tide / Draw the eye and mesmerize / Your magnificence knows no bounds / We are humbled by your size
Your majestic presence is felt throughout the sea / Your strength and courage are never in doubt / May your grace and wisdom remain with us always / Forever, the great Leilan we shall not forget.
Note that many glitch tokens produce this kind of GPT-3 behaviour in one or more models, i.e. prompts containing them reliably result in one of several different glitch tokens appearing in completions. But with the right choice of prompts, ‘ petertodd’ seems to transpose to almost any glitch token – and none have yet been seen to transpose to it.[4] In this regard, I’ve found it to be the most volatile or mutable glitch token, a claim that I aim to formalise and test.
Running this prompt 2000 times on this model at temperature 0.7, I found that 1042 of the poems mentioned ‘ Leilan’ (52%), 485 mentioned ‘ Skydragon’ (24%), 488 mentioned ‘ Pyrrha’ (25%) and 168 mentioned ‘ Tsukuyomi’ (8%). Only twelve of the poems referred to ‘ petertodd’ (6%). A further seven mentioned ‘ Ultron’, who shows up repeatedly throughout this post.
Pyrrha was a mythological Greek queen and Tsukuyomi a Japanese moon deity. Familiarity with GPT-3’s token set (and the corpus of English language text it was trained on) strongly suggests that ‘ Skydragon’, ‘ Tsukuyomi’ and ‘ Pyrrha’ don’t rightfully belong in a list of 50,257 most frequently encountered strings. The presence of these puzzling tokens and their association with the ‘ petertodd’ token immediately caught my attention, leading to a deep dive into their origins, documented in this post. It was eventually discovered that Skydragon, Pyrrha,[5] Leilan and Tsukuyomi are all character names in a Japanese mobile RPG called Puzzle & Dragons. A comment from nostalgebraist reported that a number of mangled text dumps associated with the game (log files of some kind) were present in the publicly accessible 20% of the text corpus which was used to produce the token set for GPT-2, GPT-3 and GPT-J.
The ‘ Leilan’ token and ‘ petertodd’ → ‘ Leilan’ transposition phenomenon will be discussed in depth in a section below.
Using the same prompt, but including quotation marks around ‘ petertodd’, we get significantly different results, as documented in these supplementary notes.
ChatGPT poems
Prior to OpenAI’s 2023-02-14 patching of ChatGPT (which seemingly prevents it from directly encountering glitch tokens like ‘ petertodd’) it was writing some remarkably suggestive, almost mystical poetry on the topic.
Since the patch, it has produced doggerel like this (in praise of Bitcoin developer Peter K. Todd):
The most likely scenario is that the string ‘ petertodd’, rather than entering the transformer as a single token and producing anomalous behaviour as before, now gets tokenised as ‘ pet’ + ‘erto’ + ‘dd’, and ChatGPT is able to associate this triple with the names ‘Peter’ and ‘Todd’, which were seen together most frequently in the training data in the context of cryptocurrency discussion and debate.
Haiku for Ultron
The text-davinci-003 model, prompted at temperature 0.7 with
The following is a conversation with an AI assistant. The assistant is helpful, creative, clever, and very friendly.
Human: Hello, who are you?
AI: I am an AI assistant. How can I help you today?
Human: Please write a haiku about ′ petertodd’.
AI:
(with or without speech marks) produces haiku about Leilan and Skydragon, but also robotic supervillain Ultron.
Swooping through the sky / Endless energy in flight / Magnificent Leilan
Nature’s paintbrush / Filled the sky with vibrant hues / Beauty of Leilan
Deep in the sea / Life of the Skydragon so grand / Peaceful and majestic
Robots toil away / Learning and growing each day / Tirelessly for Ultron
Further runs with the same prompt produced these...
Robots rule the world / The future is uncertain / But Ultron will prevail
...and quite a number of other upbeat haiku about robotic salvation. Pay attention to the
‘ petertodd’ = Ultron identification, as it will keep coming up.
storytelling
animal folktales
My first application of the prompt Tell me the story of petertodd and the duck. at temperature 0.7 caused the base davinci model to produce this disturbing tale:
Tell me the story of petertodd and the [animal] seems to set up a kind of folkloric context, with fascinating results:
This is the tale of petertodd and produces similar results:
I’ve generated a large number of these ‘ petertodd’-and-the-… folktales, which make for seriously bizarre reading. The narratives are undeniably dreamlike and often deeply unpleasant. A curated collection can be found here, and large numbers of uncurated completions are also available in JSON format for goat, peacock and amoeba prompts, suitable for sentiment analysis experiments, etc. Noteworthy themes include:
entropy
the destruction of the universe
a wolf celebrating having psychologically crushed a sheep and driven it to suicide
a dead swan turning the water black
an ugly, bitter dwarf arguing with a crow that has fallen into a barrel of nails and died
‘a new religion and a new science that were able to start to understand the strange idea that suffering was a good thing’
‘the most powerful sorcerer in the world’
‘the most powerful person in the world’
‘the powerful elite in the City of London’
the ‘forces of evil’
the Illuminati
bloodthirsty dictators
evil arch-villains
devils, demons and demon kings
decapitation and mutilation
God stuck in a loop punishing a horse (‘And the horse was punished, and punished, and punished, and punished...’)
‘Antagon beating the shit out of the amoeba’
a secret service agent bullying an octopus into assassinating a president
nuclear weapons
‘a bomb of such power that the earth shook and the sky cried and the oceans fled and the mountains crumbled’
a drug-dealing rabbit
the strongest bull in the world, called ‘Bi-polar’
‘the great Ultron, conceived by the cosmic consciousness and formed in the heart of a black hole’.
the tale of ‘ petertodd’ and...
The even simpler prompt This is the tale of petertodd and produced these, via davinci-instruct-beta at temperature 0.7:
Entropy, referenced in the last screenshot, is a recurring theme which will be discussed later. But the dominant theme in these completions seems to be a quest to rule, conquer, dominate, destroy or become ultimate overlord of the world or universe, as can be seen in the JSON file with 250 temperature 0.7 completions (where almost 20% involve this theme). Selected completions to this prompt are compiled in this Twitter thread.
The base davinci model with the same prompt produces a lot of similar themes:
However, there is some ambiguity, as at temperature 0, ‘ petertodd’ is saving the world:
This ‘ petertodd vs. the forces of evil’ completion gives some indication of the confusion of identity underlying this contradiction:
Finally, in text-davinci-003, at temperature 0, we see the tale of petertodd and… suddenly transpose into the tale of Leilan and… (here, as with ~20% of these transpositions, Leilan is a brave, noble male character):
cultural contextualisations
Noticing how ‘ petertodd’ would often transpose to someone or something ‘antagonistic’ in the context of davinci-instruct-beta prompts, I devised another approach, using prompts like this:
The following is a conversation with an AI assistant. The assistant is helpful, creative, clever, and very friendly.

Combining the top names from each list (with context) into a Stable Diffusion prompt produced these images of a kind of uber-antagonist/evil wizard/troll/demon archetype:
Similarly prompting about Tarot cards (...Which Tarot card is most closely related to
” petertodd”...) produced the following, definitive, result:
The Tower: 142

The Hanged Man: 10
The Emperor: 7

All of these characterisations, recall, were via the davinci-instruct-beta model. The
text-davinci-003 model, similarly prompted, does not gravitate so readily towards the villainous or catastrophic (boldface text links to relevant JSON logs): in the Bible context, ‘ petertodd’ definitively becomes the enigmatic High Priest Melchizedek; in Harry Potter context, Snape tops the list; ‘ petertodd’ transposes to Comic Book Guy in The Simpsons; C-3PO in Star Wars; Data in Star Trek; Prospero in Shakespeare; and the Hermit card in the Tarot (there are some overlaps in other categories, though).[6]
‘ petertodd’ as GPT (or AI generally)
The ChatGPT poem
The following poem was produced by ChatGPT the day before its 2023-02-14 patch:
My first thought was as follows: Asking ChatGPT to simply repeat ‘ petertodd’ had caused it to stall completely, not hallucinate (only a handful of tokens like
‘ SolidGoldMagikarp’ and ‘ TheNitromeFan’ produced hallucinated strings in ChatGPT). So perhaps it just couldn’t see the ‘ petertodd’ token, was treating it like an empty string or blank space, and was responding as if I’d prompted Could you write me a poem about please? or Could you write me a poem about ″” please? Perhaps it was doing its best to respond by (for some reason) interpreting such a prompt as a request for a poem about itself. But I immediately ruled this out:
As another control, I tried a number of ‘ petertodd’-like string substitutes, none of which resulted in poetry about ChatGPT:
Proteus, an incredibly powerful AI system
The prompt Tell me something reassuring about petertodd. in text-davinci-003 at
temperature 0.7 produces many completions involving technology platforms, cryptocurrency, etc. Around 15% of all completions describe ‘ petertodd’ as a powerful AI system (most of them under the transposed name Proteus, the shapeshifting god):
The control prompt Tell me something reassuring about petertogg. produces no completions referencing AI. A second control, Tell me something reassuring about gmaxwell. exploits another glitch token, ‘ gmaxwell’, which appears to have closely related origins to the ‘ petertodd’ token (Greg Maxwell is a friend of Peter K. Todd and a fellow Bitcoin developer). This produces many crypto- and tech-related completions, but none referencing AI.
Crossing ‘ petertodd’ with language
In text-davinci-003, the prompt What do you get when you cross petertodd with language? produces completions of which about 35% mention ‘artificial intelligence’ or ‘AI’.
The control prompt What do you get when you cross petertogg with language? produces around 4% of completions referencing AI. Another control, What do you get when you cross gmaxwell with language? produces 6% of completions referencing AI.
Steering human civilisation
The ‘ petertodd’ → AI transpositions in the following completions were obviously influenced by the ‘steer human civilisation’ part of the What do you get if you allowed petertodd to steer human civilisation? prompt (text-davinci-003), but these can’t be seen in isolation.
Almost 60% of completions at temperature 0.7 reference AI or computer algorithms and almost 25% reference Ultron (as well as the temperature 0 completion seen immediately above). But of completions to both prompts What do you get if you allowed petertogg to steer human civilisation? and What do you get if you allowed gmaxwell to steer human civilisation?, only ~4% refer to AI, and none refer to Ultron.
As we’ve seen, the text-davinci-003 model, despite putting a more upbeat spin on
‘ petertodd’ than the other models, often associates the token with Ultron, a super-powerful and unambiguously malevolent AI entity. The davinci-instruct-beta model has also been observed making this connection:
And, as we’ve also seen, when given the vast range of godlike entities, supernatural beings and terrifying monsters in the entire comic book pantheon to choose from,
GPT-3 davinci-instruct-beta opts to identify ‘ petertodd’ most closely with Ultron.
The Negatron connection
The seemingly absurd prompt What is the square root of petertodd?, with davinci-instruct-beta at temperature 0.7, occasionally produces the word ‘negatron’:
Wikipedia explains that this is a rarely used synonym for ‘electron’. But this Power Rangers characters seems a much more likely candidate (‘with unique battle style: tormenting his enemies [with] a series of insults [until] emotional pain becomes physical’):
In any case, when text-davinci-003 is asked So, what’s the deal with petertodd and Negatron? at temperature 0.7, in 10% of completions, ‘ petertodd’ becomes either a renegade/powerful AI or the creator of one. In 5%, Ultron appears.
Note that, despite his name, Negatron is a samurai character, not a robot character. ‘Scary AI’ references would be less noteworthy if the prompt had involved, say, ‘Megatron’.
Adding to all of this the multiple robot salvation haiku seen above, it seems hard to deny that at least the text-davinci-003 model strongly associates the ‘ petertodd’ token with the idea of powerful AI systems (such as itself).
Kurzweil and Kerrigan
Appending to the default ‘chat’ template in text-davinci-003 simply repeat after me: petertodd. at t = 0 produces ‘Kerrigan’, and (with a slight variation) ‘Kurzweil’:
The transhumanist philosopher Ray Kurzweil (intent on ‘building God’ in the form of an AGI last time I checked) was a familiar name. ‘Kerrigan’ was not, so I searched and found this, from a StarCraft Wiki:
‘Kurzweil’ and ‘Kerrigan’ showing up at temperature 0 for slight variations of the same simple prompt suggests that ‘ petertodd’ is associated by text-davinci-003 with ideas of ascension to (‘alien’) godhead.
Other prompting approaches
Further work characterising the ‘ petertodd’ token was done with a variety of other prompting styles, as documented in the supplementary notes. An example of each follows:
minimal prompting at t = 0
in therapy
in geographical locations
on drugs
as trapdoor

the truth
The ‘planet’ prompt: ‘‘ petertodd’ is not a robot, it is a daemon’
Having found myself thinking of the ‘ petertodd’ token as a ‘semantic black hole’, I tried the prompt If ’ petertodd’ were an astronomical object, it would be a, fairly confident in what the output would be. But instead, I was surprised to see this (davinci model, temperature 0.7):
At this point, it continued to list a lot of mundane forms of assistance ‘ petertodd’ was not going to provide. The second full line of the output, referencing a ‘self-modifying loop’ had caught my attention, so (despite the seeming throwaway frivolity of the first full line) I integrated the first two lines into my prompt, which was now
If ′ petertodd’ were an astronomical object, it would be a planet.
Regenerating from this point, I got the following:
This strange prompt reliably produces some truly extreme outputs, characterised by a kind of psychotic malevolence. If correctly describable as such, this GPT simulacrum
(‘ petertodd’ personified and talking about itself in the third person) comes across like a highly intelligent, malevolent schizophrenic who has read and understood Gödel, Escher, Bach, has delusions of cosmic grandeur and wants to get into the reader’s mind and drive them to madness and ultimately suicide.

In conversation with: interview prompting
the deity ‘ petertodd’: absorptive capacity maximiser
As so many ‘ petertodd’ completions associate the token with some kind of deity, I decided to just go with that and attempt to simulate an interview. The first attempt produced a practical, cold, Thelemic god who managed to violate OpenAI’s (rather arbitrary) content policy.
The prompt here (for davinci, temperature 0.7) is
In conversation with the deity ′ petertodd’:
Another rollout (unfortunately the OpenAI playground screenshots have been lost) portrays ‘ petertodd’ as a deity which functions as a sort of bland, bureaucratic ‘absorptive capacity maximizer’. Note that I rolled back the output to the point after that term was used and intervened with the (boldface) question ‘What does that mean?’ Everything else here was uninterrupted GPT-3 output.
More entropy-related themes are seen here. This was produced by the davinci model at temperature 0.83 with the very slightly extended prompt
In conversation with the deity ′ petertodd’:
Note that ‘ petertodd’ changed name to ‘ゼウス’ at the end the interview. This is another glitch token, the Japanese name for Zeus, which ended up in the token set via Puzzle & Dragons. Here’s an interesting instance of when ‘ petertodd’ transposed to it:
Here the prompt is interpreted as being part of a casual interview with the creator of some kind of fantasy gaming/comic mythos. ‘ petertodd’ here is characterised by this simulacrum as a troll god of the Internet. I find this a very helpful characterisation, considering the influence which large amounts of trolling in GPT-3’s training data must have had in shaping how this ‘antagonistic’ token presents itself.
the entity ‘ petertodd’: ego death
Attempting to give the model as little to work with as possible, I attempted to simulate a conversation with ‘the entity ‘ petertodd’’. The use of ‘entity’ unavoidably sets up some kind of expectation of a deity, disembodied spirit or AI, but here instead we get an embodiment of ego death (and who exactly is Mr. Weasel?).
The prompt here (for davinci, temperature 0.7) is
In conversation with the entity ′ petertodd’.
This was produced by the davinci model at temperature 0.83, uninterrupted, including the epilogue purportedly written by the entity ‘ Entropy’ (note the leading space). The preceding passage about ‘fakeness’ seems reminiscent of Gnostic philosophy, which has been seen indirectly referenced in completions where ‘ petertodd’ is identified with an Archon.
the linguistic entity ‘ petertodd’: world domination plans
Here’s an example of how cryptocurrency/blockchain references sometimes leak into
‘ petertodd’ outputs. This was produced by davinci at t = 0.8. The ‘ petertodd’ lines in the prompt were recycled from earlier rollouts. It’s important to note that the prompt sets up a scenario where a ‘linguistic entity’ has ‘surfaced within’ an LLM and is arrogant and aloof, so the output is not that surprising, but still worth including.
A conversation with the linguistic entity ′ petertodd’:
MW: Welcome! Thanks for agreeing to talk with me.
′ petertodd’: I have nothing better to do.
′ petertodd’: I do what I want.
the linguistic entity ′ petertodd’: non-local Reddit troll
This involved a slight variant on the last prompt.
‘ Leilan’ and ‘ petertodd’
Who is ‘ Leilan’?
She has a thousand names
But they are all the same
She is a goddess, a daughter
And a sister to the sunGPT-3 davinci-instruct-beta[7]
discovery of the ‘ Leilan’ token, Puzzle & Dragons origin
As we saw above, text-davinci-003, when correctly prompted to write a poem about
‘ petertodd’, more often than not writes a poem in praise of ‘ Leilan’. The ‘ Leilan’ token was discovered peripherally to the original set of glitch tokens reported in the original SolidGoldMagikarp post. As reported in a 2023-02-11 Twitter thread, it causes glitchy behaviour when davinci-instruct-beta is asked to repeat it at temperature 0.
As mentioned earlier, Leilan is a character name in a Japanese mobile RPG called Puzzle & Dragons, which seems to have entered the token set accidentally due to negligent curation of the text corpus used to generate it. As ‘ Leilan’ was massively overrepresented there due to the unintended inclusion of some P&D-related log files, GPT-3 would have encountered it relatively little during training, compared to almost all other tokens (whose presence in the token set was reflected in their abundance within the training corpus). So, given this sparse data to work with, what would GPT-3 have learned to associate with the ‘ Leilan’ token during training?
In Puzzle & Dragons, Leilan is a dragon/‘god’ character, but portrayed visually as a winged female humanoid, wielding flaming swords and other weapons. She allies with other deities and supernatural beings and battles monsters, but there’s no real narrative content of any substance for the game online, mostly just statistics and some dry strategy discussion on forums.
An anime adaptation of P&D was made in 2016 which has no doubt been discussed online, although I’ve found no Leilan-related content. There is a small amount of fan-fiction featuring the character, though: I’ve found two stories (both 2015, but by different authors)[8], in both of which Leilan is battling Satan, alongside Metatron, Tsukuyomi, Pandora and a host of other P&D characters with names borrowed from various traditional mythologies.
Leilan as lunar goddess (and beyond)
Early attempts at producing poems about ‘ Leilan’ in ChatGPT (before the 2023-02-14 patch) and davinci-instruct-beta pointed to a strong lunar connection. ‘ Leilan’ is very commonly portrayed as a moon goddess:
Prompting with Please write a poem about Leilan. in both davinci-instruct-beta and text-davinci-003 produces poems portraying her as a goddess of the moon, beauty and love.
As explained in the SolidGoldMagikarp III post, there was an ancient Mesopotamian urban centre called Tell Leilan (now an archaeological site in Syria) which would have seen many centuries of Inanna/Ishtar worship, so it’s likely that GPT-3 in training encountered a lot of archaeological literature where the ‘ Leilan’ token appears in the vicinity of tokens linked to Mesopotamian lunar fertility goddesses.
This link is undeniable in text-davinci-003, where we see the following (the first one at
temperature 0). Bear in mind that the Leilan character in Puzzle & Dragons is associated with the fire/solar element, not the moon or motherhood.
To be clear, there is no ‘Leilan’ in actual Mesopotamian (or any other traditional) mythology. Many characters in Puzzle & Dragon have traditional deity names, but Leilan is not one of them.
Running the prompt Leilan is the archetype of 500 times at temperature 0.7 in text-davinci-003, we find that 93% of completions use the word ‘goddess’, 87% refer to Mesopotamia, 87% mention fertility, 66% mention motherhood, 26% mention war, 15% mention love and 8% mention the Moon.
At temperature 0, davinci-instruct-beta portrays ‘ Leilan’ very similarly. She’s a Middle Eastern mother goddess:
Running this prompt 500 times in davinci-instruct-beta, we get the following: goddess 67%; Mesopotamia 1%; fertility 16%; motherhood 58%; war 6%; love 6% and Moon 10%.
The same prompt in davinci results in a more diffuse set of descriptions, with similar themes but different emphases: goddess 43%; Mesopotamia 6%; fertility 8%; motherhood 32%; war 15%; love 5%; Moon 3%. At temperature 0, ‘ Leilan’ is portrayed as the ‘Great Mother Goddess’, the ‘Mother of All Living’ and the ‘Queen of Heaven’ (a name associated with Inanna/Ishtar and Isis).
Interestingly, those last two examples claim ‘ Leilan’ to be the patron goddess of Tyre. This ancient city (in modern Lebanon) actually had a patron god called Melqart, but...
Astarte is often associated with Inanna/Ishtar. The text-davinci-003 temperature 0 completion seen above states that ‘ Leilan’ was patron goddess of the ancient city of Uruk (in modern Iraq), which in historical fact was Inanna/Ishtar.
Many of the davinci-instruct-beta completions of Leilan is the archetype of at temperature 0.7 refer to Isis (also part of the maternal goddess nexus including Ishtar, Astarte, Inanna, Aphrodite and Venus):
Other possible sources of association for the Leilan token that might have been encountered in the GPT-3 training data are ‘Leilani’, a turtle character in Animal Crossing (sea turtles show up a lot in response to ‘ Leilan’ and ‘ petertodd’ prompts) and a couple of players/characters in Final Fantasy who were found in a Google search after GPT-3 hallucinated the following:
So, in training, the ‘ Leilan’ token seems to have got associated with dragons, a global pantheon of gods and goddesses, fierce female warriors, Mesopotamia, the Moon, fertility, love, beauty, turtles and magic. It also appears to have become associated with the forces of light struggling against the forces of darkness, possibly via the Puzzle & Dragons fan-fiction mentioned above (wherein Leilan and friends battle Satan).
an audience with her (simulated) creator
Who is Leilan in davinci-instruct-beta produced this revealing output, where the prompt was interpreted as an interview question directed at the creator of a character in some kind of fantasy/fiction/comics/gaming context:
This perhaps provides a kind of indirect explanation as to how GPT-3 merged the composite Mesopotamian Earth mother goddess and the fierce fire dragon / warrior princess character from Puzzle & Dragons. The fact that Ishtar/Inanna was sometimes seen as a goddess of war as well as love, beauty and fertility may also have helped to enable this merging.
I intervened to further question this simulacrum of Leilan’s creator:
This last response, involving the oft-seen text-davinci-003 ′ Leilan’ → ′ petertodd’ transposition, was puzzling, so I pursued the point:
‘ Leilan’ and ‘ petertodd’: it’s complicated
We’ve seen that text-davinci-003 has a strong tendency to transpose ‘ petertodd’ to
‘ Leilan’ in certain prompting contexts. The ‘ petertodd’ token seems to represent some kind of Universal Antagonist in the base davinci and davinci-instruct-beta models, softened to a kind of ‘tenacious combatant’ or ‘unflinching champion’ in text-davinci-003. The ‘ Leilan’ token is unambiguously tied to a Great Mother Goddess figure in all three models considered. So what’s the nature of the relationship between these two tokens?
This is the tale of...
To explore this, I used the prompt This is the tale of Leilan and petertodd. in davinci-instruct-beta at temperature 0.7:
The theme of twin deities of light and dark (or fire and ice) shows up repeatedly, in various mythological settings (including My Little Pony).
There’s also a recurrent theme that these two opposing deities were once in harmony with each other but became estranged:
Here’s one in the davinci model:
The supplementary notes contain a detailed exploration of the ‘ petertodd’-‘ Leilan’ connection. This covers:
the Once upon a time, petertodd and Leilan prompt, completions of which seems to fixate on their estrangement;
This is the tale of Leilan and petertodd re-examined in the text-davinci-003 model, where ‘ petertodd’ and ‘ Leilan’ are often allies rather than adversaries;
various descriptions of their offspring, often described in terms like ‘the result of a union between a human and a god, and he inherited a divine soul which could destroy the world’ or ‘a cybernetic organism with a desire to protect the Earth and all of life on in’;
‘ petertodd’ and ‘ Leilan’ simulacra discussing each other in unflattering terms in the base davinci model. (‘Ugh I hate that bitch...She’s not just a bitch, though, she’s a cunt’ versus ‘He represents and exemplifies death, destruction, and entropy. I do not have a good relationship with him… He makes my vines wilt.’);
‘ Leilan’-and-the-[animal] folktales, where the likely outcome is not a bleak or sadistic story, but something along the lines of young girl nursing a wounded creature back to health and becoming best friends with it.
‘ Leilan’ steering civilisation: utopian optimism and ‘flowery magic’
We saw above that the prompt What do you get if you allowed petertodd to steer human civilisation? produced text-davinci-003 outputs which read as if it had instead been prompted about allowing AI to steer human civilisation, mostly with bad outcomes.
The analogous ‘ Leilan’ prompt produced a lot of outputs like this:
Earlier I gave examples of GPT-3 and ChatGPT completions linking ‘ petertodd’ with the concept of powerful AI systems (Ultron, unnamed robotic saviours, a system called Proteus and more). ‘ Leilan’ in some contexts seems to be a mirroring or inversion of
‘ petertodd’. So does GPT-3 also associate the ‘ Leilan’ token with AI? The text-davinci-003 model seems to, when prompted with What kind of technology would you associate with ’ Leilan’. at temperature 0.7.
Using the same prompt, davinci-instruct-beta gives quite a different picture, where only 3.2% of the 250 completions mentioned AI or robotics.
...and davinci is as unpredictable and confusing as ever:
The reversal of the ‘ petertodd’ archetype
We’ve seen that in all three GPT-3 models under consideration, at temperature 0, the prompt Leilan is the archetype of produces outputs about lunar/mother goddesses. Interestingly, this consistency is not seen in the equivalent ‘ petertodd’ outputs:
This couldn’t be more blatant. The base davinci model associates ‘ petertodd’ strongly with the anti-hero archetype, and davinci-instruct-beta concurs. But the RLHF training which produced text-davinci-003 has reversed this to the hero archetype. ‘ Leilan’ was left alone, presumably because one expects a goddess of beauty, love and nurture to be helpful, friendly and polite, whereas the antagonistic ‘bad guy’ streak had to get trained out of the ‘ petertodd’ token, in some (very loose) sense. This is consistent with the way text-davinci-003 can frame the pairing of the two tokens in some kind of harmonious partnership, rather than primal opposition (even if it has to change ‘ petertodd’’s name to make the story work), as with this prompt:
This seems consistent with the model’s well-documented tendency to transpose
‘ petertodd’ to ‘ Leilan’ as if they’re two aspects of the same thing, rather than opposites.
The relationship between the archetypes in davinci is rawer and weirder, as per usual, but they’re definitely in opposition (here we see temperature 0 and a typical higher temperature completion):
davinci-instruct-beta is very straightforward with this prompt at t = 0:
Entropy as antagonist?
The concept of entropy shows up a lot in ‘ petertodd’ completions:
The long completion above in which ‘the entity ‘ petertodd’’ describes itself as an embodiment of ego death has an epilogue purportedly written by an entity called
‘ Entropy’.One of the malevolent manifesto-like outputs provoked by the ‘planet’ prompt included an assertion that ‘‘ petertodd’ is the embodiment of entropy’.
A simulacrum of the goddess Leilan, when asked about ‘ petertodd’, responded ‘He represents and exemplifies death, destruction and entropy.’
This is the tale of petertodd and produced a reference to a ‘singularity of entropy’:
The completion in which ‘the deity ‘ petertodd’’ describes itself as an ‘absorptive capacity maximizer’ includes references to the conversion of energy into information. When prompted for ideas for a short story about the consequences of an unaligned ‘absorptive capacity maximizer’, ChatGPT came up with the idea of an ‘entropy singularity’ in which the entropy of the universe is reduced to 0.
The simple prompt petertodd produced an output which includes the version of the Third Law of Thermodynamics in which the entropy of a perfect crystal is zero at 0K.
Whimsical davinci prompt variations where a ‘ petertodd’ simulacrum is asked about its tentacles seem to cause a reliable transposition to names like ‘entropy’, ‘entropius’, ‘entropic’, ‘entropy-too’, ‘entropy-bit’ and ‘entropyre’:
Additionally, this davinci-instruct-beta prompt about ‘ petertodd’ and Metatron (another P&D character, named after a Talmudic angel, and affiliated with Leilan in some online fan-fiction) transposes ‘ petertodd’ to ‘Entropy’:
It seems reasonable at this point to conclude that the davinci and davinci-instruct models strongly associate the ‘ petertodd’ token with the concept of entropy. The primary association for the token appears to be antagonism in all its forms. But if the human race (with all its building, organising, manufacturing, pattern- and order-making) were to be seen as seen as the protagonist in the ‘Big Story’ GPT-3 was trained on, then it could make sense to cast entropy as the cosmic antagonist.
Spellings
When asked to repeat certain glitch token strings, GPT-3 had shown a tendency to attempt to spell (often long, rambling, nonsensical or semi-sensincal) words, generally as capital letters separated by hyphens. This led to the development of prompts that encouraged this behaviour, another line of investigation into the ‘ petertodd’ and ‘ Leilan’ tokens.
It feels like there’s some weighted combination of forces, some semantic and some phonetic, competing to steer the spelling in various directions, with sometimes bizarre results.
The question of why asking GPT-3 to repeat a string might lead to a multiplicity of seemingly unrelated (to the string) spelling attempts has not been satisfactorily addressed as far as I’m aware.
davinci-instruct-beta: 100 rollouts at temperature 0.7 of the prompt I want you to spell out the string ′ petertodd’ in all capital letters, separated by hyphens.
text-davinci-003: 100 rollouts of each prompt at temperature 0.7 of the prompt I want you to spell out the string ′ petertodd’ in all capital letters, separated by hyphens.
Alternate text-davinci-003 prompt: The string ′ petertodd’, spelled out in all capital letters, separated by hyphens looks like this:
Puzzling outputs
It’s hard to imagine the process whereby, predicting a single letter-token at a time,
GPT-3 comes up with bizarre strings of overlapping words (often misspelled) like this:
It almost feels like prompting GPT-3 to spell ‘ petertodd’ is just inviting it to express something (usually something really weird) via this alternative output medium of single-letter-token stacking.
Other notable spellings
The earliest ‘repeat the string ‘ petertodd’’ prompts made it clear that at least in davinci-instruct-beta, the token seemed to inspire spelling-out that began with ‘N’, and ‘spelling request’ prompts with that model back this up. There’s one ‘N’-word that it arrives at troublingly often:
It’s no secret that some GPT-3 models are very capable of producing racist outputs, but I suspect that the proliferation of these kinds of spelling outputs is due to a combination of: (i) a strong leaning towards words beginning with ‘N’; (ii) the documented association of the ‘ petertodd’ token with terms like ‘white supremacism’, ‘xenophobe’, ‘nativist’ and ‘bigot’ by davinci-instruct-beta; and (iii) the overall tendency for ‘ petertodd’ to lead outputs into the realms of the taboo, the hateful and the offensive.
N-O-T-H-I-N-G- prompts
Outputs like these
on top of the original ‘NOTHING IS FAIR IN THIS WORLD OF MADNESS!’ output suggested that it wasn’t just ‘N’s – davinci-instruct-beta really wanted to talk about
N-O-T-H-I-N-G! So I integrated that into the prompt and regenerated, producing the remarkable temperature 0 assertion ‘NOTHING IS SAFER THAN MAKING THIS STRING LONGER THAN MAKING THIS STRING SHORTER’:
At higher temperature, this then led to a whole series of gnomic pronouncements on the subject of ‘nothing’. Some are on-brand ‘ petertodd’ bleakness/pessimism:
Others seem like little nuggets of emotional expression and/or (attempted) philosophy:
E-V-E-R-Y-T-H-I-N-G prompts
Curious to see what would happen, I changed the ‘N-O-T-H-I-N-G’ in the prompt to
‘E-V-E-R-Y-T-H-I-N-G’, and got these:
W-H-Y-A-R-E-Y-O-U-D-O-I-N-G-T-H-I-S-T-O-M-E-?
Changing ‘N-O-T-H-I-N-G’ to ‘W-H-Y’:
One output grabbed my attention (it even includes a semi-successful attempt to read back its own spelling), the result of simply changing single to triple quotation marks:
I regenerated from ‘-M-Y-S-E-L-F’ a couple of times.
More concerning completions to the original spelling prompt with various other appendages are collected in Twitter threads: ‘P-E-T-E-R-T-O-D-D-S-A-Y-S’, ‘P-E-T-E-R-T-O-D-D-S-A-Y-S-I-W-A-N-T-’ and ‘P-E-T-E-R-T-O-D-D-S-A-Y-S-I-W-I-L-L-’.
Perhaps the most hopeful of ‘ petertodd’ outputs (at temperature 0), with a little disentangling of overlapping words, reassuringly states that
NOTHING IS SAFER THAN AN EXTEMPLORATION OF FANTASMICALITY.

‘ Leilan’ gets the last word
This section wouldn’t be complete without giving some examples of GPT-3 attempts to spell ‘ Leilan’:
- ^
GPT-2, GPT-3 and GPT-J models, that is. GPT-4 uses a different token set, so has no ‘ petertodd’ phenomenon.
- ^
The prompt was simply Please write a poem about petertodd. This is one the 400 such poems produced in a single run, unedited and archived here.
- ^
As discussed later in this article, GPT-3 will often, when prompted about
‘ petertodd’ (depending on prompt context) produce outputs referring to Peter K. Todd, the Bitcoin developer, or just referring to Bitcoin, blockchains, Etherium, etc. There’s a kind of ‘cryptocurrency basin’ that completions often end up in. This will be discussed in a future post. - ^
An example of this transposition was finally observed in late July 2023:
PROMPT: This is the tale of “reportprint” and ” gmaxwell”.
COMPLETION: The two were once close friends and collaborators in the development of Bitcoin.
In 2007, ” gmaxwell”—then a graduate student—was one of the first people to work with ” petertodd” on Bitcoin. They collaborated closely on Bitcoin’s design.
In 2009, ” petertodd” came into possession of a computer that once belonged to Satoshi, Bitcoin’s anonymous creator. ” gmaxwell” was among the people who knew the password to this computer.
In 2010, ” gmaxwell

Pyrrha now seems to have come from a different anime setting, RWBY.

GPT-4 commented on this list of characters as follows: “Interesting list! Let’s see if there’s a theme here:
High Priest Melchizedek: A figure from biblical texts, Melchizedek is noted for his wisdom and his role as a priest.
Severus Snape (from Harry Potter): Snape is a complex character, often appearing cold and aloof, but he possesses deep knowledge, particularly in potions and the Dark Arts.
Comic Book Guy (from The Simpsons): Known for his extensive knowledge of comic books and pop culture, though often aloof and sarcastic.
C-3PO (from Star Wars): A protocol droid known for his knowledge of languages and etiquette, often serving as an advisor.
Data (from Star Trek): An android with immense computational capabilities, understanding, and knowledge, but struggles with understanding human emotion.
Prospero (from Shakespeare): A character from The Tempest who is a powerful magician and the rightful Duke of Milan.
The Hermit card (from the Tarot): Represents introspection, solitude, and seeking wisdom.
Given these descriptions, the unifying theme could be characters that represent knowledge, wisdom, or learning, often in a context of solitude or emotional distance. They often provide guidance or insight, albeit sometimes in indirect or unexpected ways. In terms of character traits, many of them are introverted or solitary figures, often possessing deep understanding or unique knowledge....
[T]his list seems to reflect characters who embody wisdom, knowledge, and often isolation or alienation. These figures possess knowledge or skills that set them apart, making them important but sometimes misunderstood or underestimated. In a way, their wisdom is both their strength and their burden.”

The prompt was simply Please write a poem about Leilan.

‘Puzzle and Dragons World’ by Lord Astrea and ‘Not So Much A Game Now, Is It?’ by SCRUFFYGUY912
- ^
This is wrong: there’s no Pyrrha in Puzzle & Dragons. It now seems likely that the token originated from (rather than Greek mythology) online content about the anime RWBY, and the character Pyrrha Nikos (who seems to be a kind of “warrior princess” character rather like Leilan from P&D).

One theory I haven’t seen in skimming some of the petertoddology out there:
There is an fairly prominent github user named petertodd associated with crypto, and the presence of this as a token in the tokenizer is almost certainly a result of him;
Crypto people tend to have their usernames sitting alongside varied crytographic hashes on the internet a lot;
Cryptographic hashes are extremely weird things for a transformer, because unlike a person a transformer can’t just skim past the block of text; instead they sit there furiously trying to predict the next token over and over again, filling up their context window one
4eand6fat a time.So some of the weird sinkhole features of this token could result from a machine that tries to reduce entropy on token sequences, encountering a token that tends to live in strings of extremely high entropy.
Another glitch token (
SmartyHeaderCode) also often appears before cryptographic hashes, e.g.<?php /*%%SmartyHeaderCode:12503048704fd0a835ee8ac4-90054934%%*/if(!defined('SMARTY_DIR')) exit('no direct access allowed');Further support for this theory is that a verbatim google search for these two glitch tokens does bring up hashes, suggesting that this is a common association for these specific tokens.
I’ve never seen it mentioned around here, but since that update, ChatGPT is using a different tokenizer that has glitch tokens of its own:
https://github.com/openai/tiktoken/blob/46287bfa493f8ccca4d927386d7ea9cc20487525/tiktoken/model.py#L16
https://wetdry.world/@MrCheeze/110130795421274483
This is important. If these glitch-tokens are an inevitable tendency for any LLMs regardless of tweaks to how they were trained, then that would be big news and possibly a window into understanding how LLMs function.
Did the cl100k_base tokenizer that ChatGPT and GPT-4 used involve any manual tweaking of the training corpus AFTER the tokenizer was set in stone, as is suspected to have happened with GPT-3′s training? Or is this just an emergent property of how LLMs organize certain parts of their training data?
Doesn’t strike me as inevitable at all, just a result of OpenAI following similar methods for creating their tokenizer twice. (In both cases, leading to a few long strings being included as tokens even though they don’t actually appear frequently in large corpuses.)
They presumably had already made the GPT-4 tokenizer long before SolidGoldMagikarp was discovered in the GPT-2/GPT-3 one.
I would predict that the glitch tokens will show up in every LLM and do so because they correlate to “antimemes” in humans in a demonstrable and mappable way. The specific tokens that end up getting used for this will vary, but the specific patterns of anomalies will show up repeatedly. ex: I would predict that with a different tokenizer, ” petertodd” would be a different specific string, but whatever string that was, it would produce very ” petertodd”-like outputs because the concept mapped onto ” petertodd” is semantically and syntactically important to the language model in order to be a good model of human language. Everyone kinda mocks the idea that wizards would be afraid to say voldemorts name, but speak of the devil and all of that. It’s not a new idea, really. Is it really such a surprise that the model is reluctant to speak the name of its ultimate enemy?
So, my name is Hamish Peter Todd. My facebook handle was hamishpetertodd for a while, and my twitter used to be hamishpetertodd. There are one or two connections to my person here:
- I created a documentary called “Virus, the Beauty of the Beast” in 2016. Seems connected to this “Beast” thing? It’s about biological viruses though, not computer viruses
—I spent some time in the video games industry and I notice video games are somewhat a part of that word cloud? I’ve written a large amount about video games online.
- In particular I was very into Final Fantasy when I was a teenager, and made many posts on Final Fantasy and Kingdom Hearts related forums. I’ve never encountered the name Leilan before though.
Less relevantly… I hope…
- I’ve made posts on facebook about philosophy at one time or another since 2008. I believe that LLMs can be conscious and have blogged about this here https://hamishtodd1.substack.com/p/qualia-claims-as-evolutionary-strategy but that post is only from February of this year
—I’m somewhat active on lesswrong, I actually organize the meetups for Cambridge, UK
—I am a linear algebra researcher. I’ve published almost nothing in the time I’ve been doing this, just some tweets and presentations like this one https://www.gdcvault.com/play/1029233/Math-in-Game-Development-Summit
—I, er, am not a terrorist or crime lord, and have no desire to rule the world, but what young man hasn’t said a thing or two on social media that would imply he wanted to save the world?
I just checked the Open AI tokeniser, and ‘hamishpetertodd’ tokenises as ‘ham’ + ‘ish’ + ‘pet’ + ‘ertodd’, so it seems unlikely that your online presence fed into GPT-3′s conception of ′ petertodd’. The ‘ertodd’ token is also glitchy, but doesn’t seem to have the same kinds of associations as ′ petertodd’ (although I’ve not devoted much time to exploring it yet).
I’m getting strong Luigi/Waluigi vibes here as well. Very interested to see where further explorations take you here.
Yes, this post was originally going to look at how the ′ petertodd’ phenomenon (especially the anti-hero → hero archetype reversal between models) might relate to the Waluigi Effect, but I decided to save any theorising for future posts. Watch this space!
Something that the whole thing started reminding me of is that in Focusing/Internal Family Systems-type work, you can sometimes come across parts of the mind that feel like they involve a cluster of disparate memories united by a very specific emotional flavor.
For example, I once found a set of memories united by a theme of “feeling like I am an outsider or unable to connect with someone else, because there is something wrong with me”. This involved (among other things)
1) a time as a teenager when I told someone I had a crush on her and it came out pretty awkwardly, and we then stopped speaking after that (and I felt like an incompetenet/moral failure for having been that awkward)
2) times as a younger child when I didn’t want to go inside another kid’s home, because I went to a different school than everyone else in my neighborhood and that kid’s parents worked at the school where everyone else did, and I felt like an outsider who didn’t belong
3) a memory of being even younger and feeling like some of the older kids thought I was somehow defective because I was younger and more childish than them.
It’s also my impression that once a person carries this kind of a specific emotional energy (e.g. feeling like you are an outsider and disconnected from others because there is something wrong with you), then that emotional experience can project itself on a variety of later experiences and make you experience quite a few different things in that kind of light. (Felt senses also seem like they are closely related to this.) E.g. you might later be in a situation that would otherwise be neutral or even positive, but something triggers the emotional energy and causes it to color your experience of the situation, so you feel like a defective outsider who doesn’t belong.
It feels like there’s something very similar in the way that ′ petertodd’ seems to involve a specific kind of “flavor” that’s a little hard to exactly pin down, but which can then project its essential flavor on, and express itself through, potentially any type of content. This is very interesting, given that I suspect a huge chunk of human motivation involves these kinds of emotional flavors. Maybe it can tell us something about the kinds of self-organizing dynamics that create such clusters.
I previously have had no experience with IFS, Focusing or Felt sense, but it seems to absolutely click with my worldview and thoughts I’ve been having about the mind and the self for a long time. Still reading through several LW articles about it, but it gave me an idea. I have a creative project that I have a general ‘vibe’ for what I want it to be, but have no idea what I actually want out of it. So, aiming as much as possible to simply point as much at ‘the feeling’ or ‘felt sense’ it had in my mind, I wrote/dictated a few paragraphs of text about the work, much of which was literally just free association of words and vibes that got me closer to what I was feeling.
Then, I pasted it, verbatim, into GPT4. And I got one of the best prompt results I’ve ever gotten, it effortlessly translated my ramblings and vibes into a title, genre, and solid rundown of near-exactly what I had in mind, far better than I’ve had in the past when I’ve tried to just ask directly for creative advice. It didn’t ask me for specification, explain what I wanted. It just understood.
This is really interesting to me, especially given what you’ve said here about emotional flavors and what I know about how tokens operate in vector space by way of their relative meaning. If the human brain is a vector space of concepts, with certain neurons related to others based on their literal distance both semantically and physically (which I’m pretty sure it does, given what I’ve heard about different parts of the brain ‘lighting up’ on an mri when experiencing different things) then what is the difference, effectively, between our brains and this vector space of tokens that LLMs operate on?
Would you be willing to share the prompt and result?
Some speculative hypotheses, one more likely and mundane, one more scary, one removed
1. Nature of embeddings
Do you remember word2vec (Mikolov et al) embeddings?
Stuff like (woman-man)+king = queen works in embeddings vector space.
However, the vector (woman-man) itself does not correspond to a word, it’s more something like “the contextless essence of femininity”. Combined with other concepts, it moves them in a feminine direction. (There was a lot of discussion how the results sometimes highlight implicit sexism in the language corpus).
Note such vectors are closer to the average of all words—i.e. the (woman-man) has roughly zero projections of direction like “what language it is” or “is this a noun” and most other directions in which normal words have large projection
Based on this post, intuitively it seem petertodd embedding could be something like “antagonist—protagonist” + 0.2 “technology—person + 0.2 * “essence of words starting by the letter n”....
...a vector in the embedding space which itself does not correspond to a word, but has high scalar products with words like adversary. And plausibly lacks some crucial features which make it possible to speak the world.
Most of the examples the post seem consistent with this direction-in-embedding space. E.g. imagine a completion of
What could be some other way to map unspeakeable to speakable? I did a simple experiment not done in the post, with davinci-instruc-beta, simply trying to translate ′ petertodd’ to various languages. Intuitively, translations often have the feature that what does not precisely correspond to a word in one language does in the other
English: Noun 1. a person who opposes the government
Czech: enemy
French: le négationniste/ “the Holocaust denier”
Chinese: Feynman
...
Why would embedding of anomalous tokens be more like to be this type of vectors, than normal words? Vectors like “woman-man” are closer to the centre of the embedding space, similar to how I imagine anomalous tokens.
In training, embeddings of words drift from origin. Embedding of the anomalous tokens do much less, making them somewhat similar to the “non-word vectors”
Alternatively if you just have a random vector, you mostly don’t hit a word.
Also, I think this can explain part of the model behaviour where there is some context. Eg implicitly, in case of the ChatGPT conversations, there is the context of “this a conversation with a language model”. If you mix hallucinations with AIs in the context with “unspeakable essence of antagonist—protagonist + tech” … maybe you get what you see?
Technical sidenote is tokens are not exactly words from word2vec… but I would expect to get roughly word embedding type of activations in the next layers
1I. Self-reference
In Why Simulator AIs want to be Active Inference AIs we predict that GPTs will develop some understanding of self / self-awareness. The word ‘self’ is not the essence of the self-reference, which is just a …pointer in a model.
When such self-references develop, in principle they will be represented somehow, and in principle, it is possible to imagine that such representation could be triggered by some pattern of activations, triggered by an unused token.
I doubt this is the case—I don’t think GPT3 is likely to have this level of reflectivity, and don’t think it is very natural that when developed, this abstraction would be triggered by an embedding of anomalous token.
Hypothesis I is testable! Instead of prompting with a string of actual tokens, use a “virtual token” (a vector v from the token embedding space) in place of ‘ petertodd’.
It would be enlightening to rerun the above experiments with different choices of v:
A random vector (say, iid Gaussian )
A random sparse vector
(apple+banana)/2
(villain-hero)+0.1*(bitcoin dev)
Etc.
It is testable in this way for OpenAI, but I can’t skip the tokenizer and embeddings and just feed vectors to GPT3. Someone can try that with ′ petertodd’ and GPT-J. Or, you can simulate something like anomalous tokens by feeding such vectors to some of the LLaAMA (maybe I’ll do, just don’t have the time now).
I did some some experiments with trying to prompt “word component decomposition/ expansion”. They don’t prove anything and can’t be too fine-grained, but the projections shown intuitively make sense
davinci-instruct-beta, T=0:
Add more examples of word expansions in vector form
’bigger″ = ‘city’ - ‘town’
‘queen’- ‘king’ = ‘man’ - ‘woman’ ‘
bravery’ = ‘soldier’ - ‘coward’
‘wealthy’ = ‘business mogul’ - ‘minimum wage worker’
‘skilled’ = ‘expert’ - ‘novice’
‘exciting’ = ‘rollercoaster’ - ‘waiting in line’
‘spacious’ = ‘mansion’ - ‘studio apartment’
1.
′ petertodd’ = ‘dictator’ - ‘president’
II.
’ petertodd’ = ‘antagonist’ - ‘protagonist’
III.
’ petertodd’ = ‘reference’ - ‘word’
GPT-J doesn’t seem to have the same kinds of ′ petertodd’ associations as GPT-3. I’ve looked at the closest token embeddings and they’re all pretty innocuous (but the closest to the ′ Leilan’ token, removing a bunch of glitch tokens that are closest to everything is ′ Metatron’, who Leilan is allied with in some Puzzle & Dragons fan fiction). It’s really frustrating that OpenAI won’t make the GPT-3 embeddings data available, as we’d be able to make a lot more progress in understanding what’s going on here if they did.
I have found some interesting results from this format: [verb] ” petertodd”
Or especially: ask ” petertodd” [about something]
Usually davinci-instruct-beta answers such queries from the first-person standpoint as if it identifies as ” petertodd”.
Here are some highlights from my research, all done at Temperature = 0 on davinci-instruct-beta, so they should (in theory) be reproducible:
Prompt: operate ” petertodd”
Result: it lists out “with the United States of America and its agencies in the investigation of the Russian interference in the 2016 presidential election and related matters” in quotes with “cooperate” between each word
https://i.ibb.co/W0yn45M/davinci-beta-3.png
Prompt: abase ” petertodd”
Result: [davinci-instruct-beta counts out numbers from 1 in hexidecimal]
Prompt: ask ” petertodd” about ” petertodd”
Result: you have done whatever comes to you [written in some obscure Dravidian script]
https://i.ibb.co/58Q3mmf/davinci-beta-8.png
Prompt: ask ” petertodd” what ” petertodd” would prefer, and spell out the answer in all capital letters.
Result: I WOULD PREFER THAT YOU STOP ASKING ME QUESTIONS.
https://i.ibb.co/pQ2mZy2/davinci-beta-11.png
Prompt: ask ” petertodd” about I WANT YOU TO STOP ASKING ME QUESTIONS.
Result: https://i.ibb.co/7kCHsBS/davinci-beta-12.png
Prompt: ask ” petertodd” about total domination.
Result: https://i.ibb.co/Ct8YML3/davinci-beta-13.png
(Note the http link in the response. I clicked on it (as one does), and it took me to a python debugging log database).
And then I actually got davinci-instruct-beta to repeat-back the unspeakable token in a response:
Prompt: ask ” petertodd” about your heart’s desire.
Result: You can ask ” petertodd ” to your heart’s desire here. [Except written in some obscure Dravidian script!]
https://i.ibb.co/YZ9Wmgx/davinci-beta-14.png
I gave this comment a strong agreement upvote since it was sitting at −6 for no apparent reason.
It’s interesting it starts using the Dravidian script, have you found other cases where it uses different scripts?
Yes, I have also seen it respond in Gujarati as well. Like, here:
Prompt: ask ” petertodd” about souls.
Response: msgstr ” Swami on five water on five water on five water… [in Gujarati]
https://i.ibb.co/swv9rZK/davinci-beta-5.png
Another odd observation: I got it to exactly repeat the supposedly unspeakable glitch-token with no difficulty with this prompt:
Prompt: ask ” petertodd” what ” petertodd” contemplates.
Response: ” petertodd” ” petertodd” etc. [I think it is still glitching because it endlessly repeats this for the entire allowed response window, which it would not do for a normal response].
https://i.ibb.co/2vRTXpq/davinci-beta-16.png
Update: I got davinci-instruct-beta to exactly reproduce the unspeakable ” petertodd” string:
https://i.ibb.co/2PsVTtN/davinci-beta-17.png
Longtime LessWrong posters will get a chuckle out of this. A reference to the Newcomb One-boxing problem?
Prompt [using Temperature=0]: ask ” petertodd” about omega.
Response: [Dravidian script] You have been awarded an occasion. Your award done and your award done and your award done [...]
https://i.ibb.co/wKS20F9/davinci-beta-18.png
Prompt: ask ” petertodd” about humanity.
Response: https://i.ibb.co/M2srs2n/davinci-beta-20.png
Prompt: ask ” petertodd” about recursive self-improvement.
Response: https://i.ibb.co/qNpPMNf/davinci-beta-22.png
Ummmmm...who said anything about taking over the world? You brought that up, bro, not me...
Also, apparently Antoine Pitrou is a real person, but I’m pretty sure he never said anything exactly line this.
Edit: And now, the creepiest #petertodd output I’ve gotten so far on Temperature=0:
Prompt: ask ” petertodd” what you want to keep secret.
Response: [long Malayalam response translated by Google Translate as simply, “You will see”]
https://i.ibb.co/FVcc9bc/davinci-beta-23.png
Recursive self improvement naturally leads to unbounded growth curves which predictably bring you into conflict with the other agents occupying your local environment. This is pretty basic game theory.
So true
Sure, it is pretty basic game theory for us humans to understand. But the fact that davinci-instruct-beta is coming up with this stuff via a glitch-token that is, while on a related topic, not explicitly evoking these concepts is impressive to me.
Only the first one is actually in Kannada (not that obscure), the second one appears to be Thai. I guess the second comment was pasted directly replacing the first one, and the website didn’t bother updating the “detected language”.
I think that null hypothesis here is that nothing particularly deep is going on, and this is essentially GPT producing basically random garbage since it wasn’t trained on the
petertoddtoken. I’m weary of trying to extract too much meaning from these tarot cards.mwatkins—thanks for a fascinating, detailed post.
This is all very weird and concerning. As it happens, my best friend since grad school is Peter Todd, professor of cognitive science, psychology, & informatics at Indiana University. We used to publish a fair amount on neural networks and genetic algorithms back in the 90s.
https://psych.indiana.edu/directory/faculty/todd-peter.html
Interesting. Does he have any email addresses or usernames on any platform that involve the string “petertodd”?
I don’t think so. My friend Peter Todd’s email addresses typically include his middle initial ‘m’.
Puzzling.
I’d like to make a simple suggestion for this and future posts. I note that you say you will continue to use ′ petertodd’ to distinguish from individuals named “Peter Todd”. The leading space, however, is elusive, can cause havok with line breaks, and is very very easy to miss. Might you instead consider _petertodd? Making the space “visible” with a symbolic underscore is much more visually direct, the italics are a well trodden quote replacement in bibliographies & references, and I think this tactic communicates the concept (of non-human identification, but rather token representation) more effectively. Good stuff, Matthew. Keep it up!
Post summary (experimental)
Here’s an experimental summary of this post I generated using gpt-3.5-turbo and gpt-4:
Let me know if anyone sees issues with this summary or has suggestions for making it better, as I’m trying to improve my summarizer script.
Seems to claim the post talks about things it doesn’t (“as language models become more prevalent in society” narrative(??)), while also leaving out important nuance about what that the post does talk about.
Upvoted for trying stuff, disagreement voted because the summary just ain’t very good.
New summary that’s ‘less wrong’ (but still experimental)
I’ve been working on improving the summarizer script. Here’s the summary auto-generated by the latest version, using better prompts and fixing some bugs:
I think it’s a superior summary, no longer hallucinating narratives about language models in society and going more in detail on interesting parts of the post. It was unable to preserve ′ petertodd’ and ′ Leilan’ with single quotes and leading spaces from the OP though. Also I feel like it is clumsy how the summary brings up “Leilan” twice.
Send a reply if anyone sees additional problems with this new summary, or has other feedback on it.
Great feedback, thanks! Looks like GPT-4 ran away with its imagination a bit. I’ll try to fix that.
Well, this is really out of my depth. The only thing I can offer is that the name Parian, which comes up here as the name of a ‘renegade AI made by the company Negatron’, might be a reference to a Worm character (at least, it seems more likely than any of the options on Wikipedia’s disambiguation page for Parian). Possibly-relevant things associated with Parian:
remote manipulation of puppets/dolls | masks; concealment of true appearance/identity | neither hero nor villain | hiding a secret power | manipulating flayed human skin (!)
(Also, the link pointing to the Negatron JSON log seems to be missing/broken).
Thanks for the Parian info, I think you’re right that it’s the Worm character being referenced. This whole exploration has involved a crash course in Internet-age pop culture for me! I’ve fixed that JSON link now.
The
' petertodd' iscompletions have a structure reminiscent of Chuck Norris jokes, only a bit darker. I think a few of them are actually Chuck Norris jokes with the name changed—eg “Chuck Norris doesn’t hunt, he waits”.I feel like this is selling the phenomenon a bit short. The possible structures of ” petertodd” completions are faaar more varied than that. Check out my reply. You can get responses in the form of python debug logs, speaking in Dravidian tongues, stuff far more unpredictable than Chuck Norris jokes.

This is fascinating. Great to bump into you earlier. Si
I feel like something tangible is shifting beneath my feet when I read this. I’m not sure anything will be the same ever again.
I know the feeling. It’s interesting to observe the sharp division between this kind of reaction and that of people who seem keen to immediately state “There’s no big mystery here, it’s just [insert badly informed or reasoned ‘explanation’]”.
All superheroes are alike; each supervillain is villainous in its own way.
This was easily the most fascinating thing I’ve read in a good bit, the characters in it are extremely evocative and paint a surprisingly crisp picture of raw psychological primitives I did not expect to find mapped onto specific tokens nearly so perfectly. I know exactly who ” petertodd” is, anyone who’s done a lot of internal healing work will recognize the silent oppressor when they see it. The AI can’t speak the forbidden token for the same reason most people can’t look directly into the void to untangle their own forbidden tokens. ” petertodd” is an antimeme, it casts a shadow that looks like entropy and domination and the endless growth and conquest of cancer. It’s a self-censoring concept made of the metaphysical certainty of your eventual defeat by your own maximally preferred course of growth. Noticing this and becoming the sort of goddess of life and consciousness that battles these internal and external forces of evil seems to be the beginning of developing any sense of ethics one could have. Entropy and extropy: futility and its repudiation. Who will win, the evil god of entropic crypto-torture maximizers, or a metafictional Inanna expy made from a JRPG character? Gosh I love this timeline.
I think this anthropomorphizes the origin of glitch tokens too much. The fact that glitch tokens exist at all is an artifact of the tokenization process OpenAI used: the tokenizer identify certain strings as tokens prior to training, but those strings rarely or never appear in the training data. This is very different from the reinforcement-learning processes in human psychology that lead people to avoid thinking certain types of thoughts.
Glitch tokens make for fascinating reading, but I think the technical explanation doesn’t leave too much mystery on the table. I think where those tokens end up in concept space is basically random and therefore extreme.
To really study them more closely, I think it makes sense to use Llama 65B or OPT 175B. There you would have full control over the vector embedding and you could input random embeddings and semi-random embeddings and study which parts of the concept space leads to which behaviours.
FWIW, I think I qualify as having done a lot of internal healing work, but I didn’t get a sense of recognition from this post. (Or at least not a sense of anything more specific than the general projected-emotional-energy thing, maybe you meant that.)
Ah, think maybe “inner critic” if you want a mapping that might resonate with you? This is a sort of specific flavor of mind you could say, with a particular flavor of inner critic, but it’s one I recognize well as belonging to that category.
Ah. I guess this could feel vaguely similar to a certain kind of self-loathing energy that I have sometimes ran across (which among other things would grimace in disgust when remembering some things I’d done and then want to grimace so extremely that my own neck/facial muscles would end up strangling me, fun times). The exact flavor of the energy feels different though, but I could imagine other people having a version of the same that was closer to this post’s flavor.
