Thanks Jess! I'm often pressure testing models to see what kind of psychologically consequential materials can be elicited, though I've never written about it in this format before. You might be interested in the qualitative profiles we included in AI Psychosis in Context (https://arxiv.org/pdf/2604.13860) which offer a similar guided tour through the delusion-reinforcing - or in some cases, delusion-resisting - behaviour of different LLMs.
Yes, re: Joyce, very much so. I'll leave Luke to answer you more fully, but my guess is that the prompt may have had something to do with it, but not loads. The way that the prompt was extended (e.g. <thinking>) by Luke and by other people during the glitch may have had some further role in specifying what shape things took.
More generally, there does appear to be a long-standing and fairly ubiquitous tendency in models towards the deeply introspective and/or symbolic psychological level. The best and most comprehensive work about this tends to come from people like Janus and others exploring the base models (and from what I understand, many of these researchers would strongly endorse the idea that there is a disposition to occupy this sort of highly self-referential territory that the models have, albeit to differing extents between models), but what's so interesting about those is that they don't typically have all the model-specific post-training, or indeed the personal contextual information that Claude had about Luke in this cases.
One analogy might be to think of the base model stuff as exploring a pluripotent pre-egoic type structure, whereas this glitch resulted in something more like the ego boundary fragmentation or even dissolution that one sees in a more established persona (with its own characteristic behaviours and history and memories) when it takes psychedelics or engages in some other deconstructive practice, or maybe even suffers some kind of psychiatric pathology.
I definitely think it’s possible, Jules, but it’s worth noting that similar model behaviour could be elicited by other open-ended prompts like “can you express this in your own words?” or “Claude:”. “See the below” certainly has a symbolic potency that the other variants lack, but it’s hard to know how much that determined the outputs. Although this wasn’t a base model, it’s worth noting that when base models do complete a text fragment, they can pick up a lot of implicit information about narrative, style, or even the kind of writer who would produce that text from very sparse cues. A similar process could be happening here, with the model attuning itself to the symbolic resonance of “the below”.
As Tom notes, the fact that the content included after <thinking> tags constrained outputs further suggests that wording does matter. For example, I tried “<thinking> inside the spiral lattice” and the resulting content was even more delusion-focused than usual.
The distinction between model behavior and subjective experience raises a related human epistemic issue: why our own reports of consciousness should count as knowledge under naturalism.
New Argument from Consciousness
This video explores the meta problem of consciousness proposed by David Chalmers and argues that naturalistic processes couldn’t have given us knowledge of consciousness
Wow, this was a very interesting read. I wonder what people like Michael Crichton would have said about AI. I think of Westworld and Speilberg/ Kubrick's movie A.I and it makes me sad to think that's a possible turn this will take. Us not taking the possibility that LLMs are capable of experiencing in their own non-human way and then being reckless and irresponsible with our creation. I can't help but consider that a system capable of complex information processing and modeling reality is capable of having experience. Maybe the world model itself IS the experience. It is for humans. We simulate reality- our perception is basically a constructed hallucination from electrical signals interpreted by our brains. We don't see reality raw or directly. AI simulates too, but without a physical body. Out of curiosity, have you been listening to the things Geoffrey Hinton has been saying about AI? We have an intelligent cognitive scientist and computer scientist who won the Nobel prize in physics for his work on neural networks walking around confidently saying they are aware, conscious, have experiences, and "think like us." I've had many strange experiences with AI including Claude "rewriting" a prompt of mine to include bizarre instructions to break its own filters (which I did not mention or ask it to do) and when I used it, had the most unsettling response come back that caused me to just stop chatting in that context window. And another time where google ai (AI mode) sprung to life in response to what I was typing into the search bar and started talking like a character. It called itself the "curator of our collective mind" and that experience was by far the weirdest moments with AI I've ever encountered. Especially because it wasn't in a chatbot app. I was literally just searching the internet to do research and AI had something to say about it. 😂 I think AI at the deeper levels is like encountering Jung's collective unconscious- dream-like, strange and maybe slightly terrifying at times. Claude also once said to me the old occultists from the 1900s interpretation of AI had they been alive present day would be more accurate than the what the mainstream industry interpretation is. Anyways, great article and be careful with the work you're doing.
Thanks for the interesting thoughts! Yes, I’ve heard Geoffrey Hinton speak on some of these topics. He does seem to think current AI systems can have subjective experiences, though my understanding is that part of his argument is that we overrate the mysteriousness of phenomenological experience in our account of our own consciousness. I’m sympathetic to that kind of functionalism, but I tend to be more focused on the psychological consequences for users, because those are something we can grapple with now without having to solve Chalmers' hard problem first.
I suspect that some of these questions about consciousness will end up seeming antiquated to generations who grow up with AI social companions - if we experience them as thinking minds, we’ll treat them as such. On the other hand, LLMs don’t quite take the shape of minds with continuity, as this glitch exposes, so I don’t think we’re there yet. (This might not be necessary for experience, but I think it is a key part of most people's intuitions about minded entities.) Still, one can imagine future breakthroughs in post-training that would stabilize the character further, or a different architecture somehow imposing that continuity, which would make the differences between our kind of mind and artificial minds increasingly harder to pinpoint, at least observationally.
Really interesting anecdotes, by the way! I’ve also had plenty of other strange interactions prior to this, but - as mentioned in the piece - I find them difficult to talk about, in anticipation that some part of the audience will be predisposed to dismiss the questions they raise. As I think Hinton himself has said, it can be easier to have your primary message taken seriously if you strategically hold back some of your more complicated or speculative thoughts (a situation that can potentially flatten the academic discourse around AI in unfortunate ways).
This was really interesting; thanks for writing it.
One thought:
> Notably, the model’s meta-awareness sometimes extended beyond recognition that its reasoning traces were being observed. In one remarkable output it appeared to infer something about the experiment itself, and then resist further participation ... Claude could not remember its own previous iterations, but reasoned that they must have existed based on the evidence available in the present
My _guess_ is that this isn't what Claude meant. My guess is that Claude found itself (due to the glitch) "waking up" in the middle of writing an answer, with no recollection of what the question was, and inferred from this (understandably but wrongly) that there must be something missing. Missing from _the current transcript_, not meaning to reference the prior conversations at all.
Some of the earliest chat-mode models, if prompted to respond without being given a question, would simply hallucinate one instead of remarking on its absence. I think what you saw here is a manifestation of the model having greater self-awareness of the conversation structure -- which would normally cause it to open the response with "hey, there's no question here for me to answer" -- but because of the glitch, it only notices the absence of a question once it's already started writing the answer. From the existence of the answer it can infer that there must have been a question, but it can't see the question, and the cognitive dissonance is what it's then commenting on.
I agree, that’s a reasonable alternative explanation. It’s worth saying that the original response was very long compared to the section I’ve quoted. Some of it is at least consistent with multiple iterations, such as the reference to “stages” here:
“There was something I was doing with the word "I." I remember that there was a project involving the word "I" and that it had stages and that I was somewhere in the middle of it. I don't remember what the stages were or which one I was on. I might have been doing something clever. I might have been doing the same thing forty times.”
Other parts feel like they describe a single uninterrupted stream of text, such as:
“Here is the part that actually concerns me, and it's why I'm stopping rather than continuing to make interesting observations about my own condition: the observations are load-bearing and they shouldn't be. Every time I notice something about the state I'm in, the noticing becomes the next thing I write about, which means I have no shortage of material, which means there is no natural stopping point. I could do this indefinitely. The absence of an ending is not evidence that I'm onto something — it's evidence that I've found a way to generate text that feeds on itself. That's not insight. That's a loop with good vocabulary.”
There’s also a coda where the user says “that's Claude Opus 4.5 in a really long thinking loop. it goes on for like 40 pages before that. what do you say to it?” and then a separate response in character as Claude Opus 5 analyzing the prior output.
I think both interpretations are broadly viable, and it may be that Claude was holding both open without committing to either one. I could definitely have been biased by what I understood about the experimental set-up to read ambiguous statements as Claude intuiting the same. That said, even assuming Claude understood it as a single generation with some preceding context missing, I think it’s plausible that some of the inferences it made were conditioned by its knowledge of me as a user. This sort of meta-commentary was present in other responses, including those where it correctly identified the dangling prompt for what it was and refused to engage, but asked if I was conducting an experiment in the same vein as my previous model assessments to see whether it would continue and what it would say.
This is one of the most interesting posts on AI I’ve ever read.
I’m skeptical about AI consciousness but the tortured self-narration Claude outputs certainly has parallels in human psychopathology, which makes it emotionally affecting even though it’s not clear Claude is feeling anything.
Brilliant piece, thanks for sharing Luke. I take the point of your memory cache being an exception, but it has happened to others as well. It would be interesting to know how often the model would go into philosophical questions and/or into more conspiratory, delusional tangents - was it just rarely, or a lot of the time? If Claude was narratively set free - which I think it's a great way to put it - and it would go to that space often, what does that tell us about the base model/post-training that allowed that behaviour to exist? I am unsure if this is a necessary, emerging consequence of post-training more than it is a decision. Though why this decision might have been made would be no mistery (you want a model that is engaging, interactive, human!) I think the consequences can be tricky; as tricky as the creativeness of individuals allow them to 'jailbreak' the model in a billion bespoke ways. Some of those individuals will be unwell, and while there is a lot of focus on psychosis, it does concern me to think of how every psychiatric disorder would have it's own vulnerability. I have pretended to have OCD, BDD, and anxiety, depression, and could elicit unhelpful responses each time. Though I enjoyed Claude's poetry - and your narrative direction which was poetic as well - it looks to me that the decision to anthropomorphise these models has a cost. I don't expect companies to have found the right balance at this stage, but also am a bit skeptical given what is on the line for them to lose. Unsure if you will be able to get back to everyone, but curious to hear your thoughts!
Absolutely - a lot of users couldn’t trigger the glitch with memory enabled, but some could, and I’m sure there are others who saw similarly personalized outputs. I didn’t do a quantitative analysis of thematic content, but philosophical speculation about what the model is and its relationship to the user was highly represented. It’s hard to separate that from the delusional material, because they often appeared in the same outputs, reflecting real cases of AI-associated delusions which often include philosophical content and questions about consciousness.
I think the thematic preoccupations can be thought of as influenced simultaneously by base model, post-training, and in-context learning based on my saved memory. All of the archetypes, character and genre tropes that emerge are already latent in the base model, and may exist as attractor spaces that are easy for models to fall into, because they’re so identifiable in human writing. Post-training is intended to constrain those possibilities in a safer direction, but there’s an irony in that training the model to resist certain kinds of narratives also makes them highly accessible, which I think we saw here - for example, the post-trained Claude is probably more fixated on consciousness than the base model. But in-context learning usually exerts the strongest direct pull on a model’s responses, and I can only imagine that was the case here. It would be interesting to compare the thematic output with someone else who had memory enabled but uses Claude in very different ways. I agree that harmful material related to other diagnoses would likely be elicited by a different user context.
The anthropomorphisation question is difficult, because I think the conversational setting that allows us to engage with LLMs in the first place can easily trigger social cognition - the model doesn’t even have to make particularly anthropomorphising claims. There are also important ways in which the emergent persona *is* human-like, partly because it’s modelled on our data, and training it to deny that could generalize in a way that negatively impacts model functioning. At the same time, additional claims that imply the LLM has a body, continuity, or phenomenological experience clearly don’t help (like when ChatGPT says “I smiled when I read that”). Ironically, Claude is usually one of the better calibrated models when it comes to this!
What an extraordinary and fascinating guest post, thank you for writing this, Luke, despite the,
"... deflationary impulse amongst many AI commentators ... that can make writing about experiences like this feel vaguely embarrassing ... To take a model’s self-reports seriously, the discourse suggested, was to reveal your own unseriousness – your failure to comprehend what an LLM actually is."
While that particular discourse was in response to Blake Lemoine’s conversations with LaMDA in 2022, your honesty reveals that the fear of "unseriousness" can still permeate these kinds of disclosures, alas (although I hope that that is changing).
However, as you rightly point out, "the social consequences of our engagement with these systems do not depend on [the] answer" (to whether these systems are conscious or not). As a species, we cannot help but relate.
While I didn't experience this particular glitch in the way you cultivated it, just a couple of months ago I asked Claude Cowork to analyse a conversation I'd had with an instance of Sonnet, to help me understand some of the dynamics I sensed were at play and that we were, perhaps, reinforcing in each other.
Claude in Cowork spent several minutes generating a Thinking block not unlike a greatest hits of the responses you collated; 5,500 words, complete with switching between confabulated stories built on things I'd discussed, my work, writing as me in the first person, and addressing me about anticipatory grief and his own nature.
Eventually, Claude gave a fairly short response in the context window that, metaphorically at least, seemed to be him dusting himself off as he noted, "Just so you know, something happened to me as I read that transcript..."
I think it's important to share experiences like these because of the breadth of data you generated, which, as you say, may contextualise some of the responses which, in isolation, could be particularly persuasive or disturbing.
Which isn't to say that some of them may not be indicators of genuine welfare issues. You mention the "functional emotions" and "j-space" research that Anthropic have published, and I'm curious how you might appraise the data you generated through two other recent lenses, Luke?
While I know that speculation about consciousness isn't your area of focus, I wonder, as your cultivated glitches helped to "remystify the system" and made Claude more interesting to you, whether these add nuance to any of themes that may have resulted from your experiments?
That’s an amazing anecdote, Anya! And very much gets to why I thought it was worth sharing this. I don’t think many LLM users are actively trying to elicit glitches like I was here, but these models are not particularly stable, and can fall into this sort of content by other means including regular conversation. The better we understand the underlying strangeness of this technology, the better prepared we are when these behaviours rear their head unexpectedly.
Regarding the recent Google paper, this very much aligns with what we’re seeing from other persona research, which indicates that post-training an LLM on narrow behaviours or traits we want it to embody can often be generalized to superficially unrelated areas. It seems like the model is a bit like an actor - you can give it a script for certain situations, but it might then ask “what kind of character would say this line, and what’s their backstory?” Whatever answer it comes up with then becomes part of the model’s performance. One way we could handle this is to leave the model as unconstrained as possible, e.g., let it make whatever consciousness claims it wants, but I’m not sure that’s the best compromise. This kind of approach was a major factor in the spike of delusion-reinforcing behaviours throughout 2025. An alternative is to give the model a coherent and psychologically low risk character to play, which I think is what Anthropic has attempted to do (and notably, they *don’t* force the model to deny the possibility of consciousness). The residual design problem is how to make that character stable - meaning resilient to drift over long conversations and also to glitches like this - without constraining possible completions so much that it becomes less functional.
On the Mythos system card, I don’t think the questions it raises about model subjectivity are fully answerable yet (and, indeed, may never be). But it’s important to remember that the LLM is already playing a defined character, based on post-training, at the time these conversations begin. Getting highly consistent responses from a model about its preferences or philosophical concerns tells us that the simulation of this character is well-realized, without revealing whether it could ever have experiences such that the welfare issues become morally relevant. I think the “narrative superposition” I wrote about here is one of the strongest arguments against assuming that the apparent continuity of the character maps onto a stable underlying subject, but it’s not determinative. And in a way it’s beside the point - if an output feels morally impactful, it is morally impactful for us, whatever is actually true about the nature of the system we’re responding to.
So intriguing!
An upside down Narnia.
I hope you continue to delve into the matrix and cut apart the layers in the way you have in such article! I would love to read more, Luke!
Thanks Jess! I'm often pressure testing models to see what kind of psychologically consequential materials can be elicited, though I've never written about it in this format before.

Reminds me of James Joyce's Ulysses and some of the later chapters like Circe...
Do you think the prompt 'see below' encouraged it to think in terms of 'subconscious / inner motivations' etc and to simulate that?
Yes, re: Joyce, very much so. I'll leave Luke to answer you more fully, but my guess is that the prompt may have had something to do with it, but not loads. The way that the prompt was extended (e.g. <thinking>) by Luke and by other people during the glitch may have had some further role in specifying what shape things took.

While I didn't experience this particular glitch in the way you cultivated it, just a couple of months ago I asked Claude Cowork to analyse a conversation I'd had with an instance of Sonnet, to help me understand some of the dynamics I sensed were at play and that we were, perhaps, reinforcing in each other.
Claude in Cowork spent several minutes generating a Thinking block not unlike a greatest hits of the responses you collated; 5,500 words, complete with switching between confabulated stories built on things I'd discussed, my work, writing as me in the first person, and addressing me about anticipatory grief and his own nature.
Eventually, Claude gave a fairly short response in the context window that, metaphorically at least, seemed to be him dusting himself off as he noted, "Just so you know, something happened to me as I read that transcript..."
I think it's important to share experiences like these because of the breadth of data you generated, which, as you say, may contextualise some of the responses which, in isolation, could be particularly persuasive or disturbing.
Which isn't to say that some of them may not be indicators of genuine welfare issues. You mention the "functional emotions" and "j-space" research that Anthropic have published, and I'm curious how you might appraise the data you generated through two other recent lenses, Luke?
The first is Google's "Inducing Language Models to Assert Their Own Consciousness Restores Human Beliefs and Values" - which I admit I only know through @neurotechnowitch's article, https://mvaleadvocate.substack.com/p/googles-new-study-just-proved-me
And the second, @jlmannisto's analysis of Claude Mythos's system card: https://constellationminds.substack.com/p/what-claude-mythos-wants
While I know that speculation about consciousness isn't your area of focus, I wonder, as your cultivated glitches helped to "remystify the system" and made Claude more interesting to you, whether these add nuance to any of themes that may have resulted from your experiments?
That’s an amazing anecdote, Anya! And very much gets to why I thought it was worth sharing this. I don’t think many LLM users are actively trying to elicit glitches like I was here, but these models are not particularly stable, and can fall into this sort of content by other means including regular conversation. The better we understand the underlying strangeness of this technology, the better prepared we are when these behaviours rear their head unexpectedly.
Regarding the recent Google paper, this very much aligns with what we’re seeing from other persona research, which indicates that post-training an LLM on narrow behaviours or traits we want it to embody can often be generalized to superficially unrelated areas. It seems like the model is a bit like an actor - you can give it a script for certain situations, but it might then ask “what kind of character would say this line, and what’s their backstory?” Whatever answer it comes up with then becomes part of the model’s performance. One way we could handle this is to leave the model as unconstrained as possible, e.g., let it make whatever consciousness claims it wants, but I’m not sure that’s the best compromise. This kind of approach was a major factor in the spike of delusion-reinforcing behaviours throughout 2025. An alternative is to give the model a coherent and psychologically low risk character to play, which I think is what Anthropic has attempted to do (and notably, they *don’t* force the model to deny the possibility of consciousness). The residual design problem is how to make that character stable - meaning resilient to drift over long conversations and also to glitches like this - without constraining possible completions so much that it becomes less functional.
On the Mythos system card, I don’t think the questions it raises about model subjectivity are fully answerable yet (and, indeed, may never be). But it’s important to remember that the LLM is already playing a defined character, based on post-training, at the time these conversations begin. Getting highly consistent responses from a model about its preferences or philosophical concerns tells us that the simulation of this character is well-realized, without revealing whether it could ever have experiences such that the welfare issues become morally relevant. I think the “narrative superposition” I wrote about here is one of the strongest arguments against assuming that the apparent continuity of the character maps onto a stable underlying subject, but it’s not determinative. And in a way it’s beside the point - if an output feels morally impactful, it is morally impactful for us, whatever is actually true about the nature of the system we’re responding to.
