        If there truly was any introspection in these models, they wouldn’t
        hallucinate. All these cognitive processes are not just philosophical
        artifacts, but have distinct biological purposes. If you don’t find
        them serving any purpose in your model, then you’re just looking at
        noise, and your observations may not be above a statistically
        significant threshold to  derive a conclusion (because they’re
        noise).

        Makes intuitive sense for this form of introspection to emerge at
        higher capability levels.
        
        GPT-2 write sentences; GPT-3 writes poetry. ChatGPT can chat. Claude
        4.1 can introspect. Maybe by testing what capabilities models of
        certain size have - we could build a “ladder of conceptual
        complexity” for every concept ever :)

        They say it only works about 20% of the time; otherwise it fails to
        detect anything or the model hallucinates. So they're fiddling with the
        internals of the network until it says something they expect, and then
        they call it a success?
        
        Could it be related to attention? If they "inject" a concept that's
        outside the model's normal processing distribution, maybe some kind of
        internal equilibrium (found during training) gets perturbed, causing
        the embedding for that concept to become over-inflated in some layers?
        And the attention mechanism simply starts attending more to it =>
        "notices"?
        
        I'm not sure if that proves that they posses "genuine capacity to
        monitor and control their own internal states"

          Edit: In my opinion at least, maybe they would say that if models are

        That blog post is marketing. If I'm calling their APIs to get code

        consider that an introspective cognitive task or not. Either the
        response from their API provably conforms to the specification or it
        doesn't. Furthermore, the more I read metaphysically confused nonsense
        like this & the more I see Dario Amodei wax incoherently about AI

        incoherent philosophical projects instead of actually improving the
        software for writing provably correct code.
        
        I do not care what's happening to the GPU in the data center according
        to the theoretical philosophy department at Anthropic. I simply want to
        know whether the requirements I have are logically consistent & if they
        are I want a provably correct implementation of what I specified.

            It’s clearly not a stochastic parrot now that we know it

              Your second claim here is kind of falling into that same
              religion-esque certitude.
              
              From what I gathered, it seems like "introspection" as described
              in the paper may not be the same thing most humans mean when they
              describe our ability to introspect. They might be the same, but
              they might not.
              
              I wouldn't even say the researchers have demonstrated that this
              "introspection" is definitely happening in the limited sense
              they've described.
              
              They've given decent evidence, and it's shifted upwards my
              estimate that LLMs may be capable of something more than
              comprehensionless token prediction.

                Nope it’s not. We have logical causal test of introspection.
                By definition introspection is not stochastic parroting. If you
                disagree then it is a linguistic terminology issue in which you
                disagree on what the general definition of what a stochastic
                parrot is.

                Doesn’t need to be the same as what humans do. What it did
                show is self awareness of its own internal thought process and
                that breaks it out of the definition stochastic parrot. The
                criteria is not human level intelligence but introspection
                which is a much lower bar.

                This is causal evidence and already beyond all statistical
                thresholds as they can trigger this at will. The evidence is
                beyond double blind medical experiments used to verify our
                entire medical industry. By logic this result is more reliable
                than modern medicine.
                
                The result doesn’t say that LLMs can reliably introspect on
                demand but it does say with utmost reliability that LLMs can
                introspect and the evidence is extremely reproducible.
                
                By logic your stance is already defeated.

                  That's not remotely close to "at will".
                  
                  As I already said, this does incline me towards believing 
                  LLMs can be in some sense aware of their own mental state.

                  researchers' best efforts only yielded a twenty percent

                  If they could in fact produce this at will, then my
                  confidence would be much higher that they've shown LLMs can
                  be self-aware.

                    You are misunderstanding what “at will” means in this
                    context. The researchers can cause the phenomenon through a
                    specific class of prompts. The fact that it does not occur
                    on every invocation does not mean it is random; it means
                    the system is not deterministic in activation, not that the
                    mechanism is absent. When you can deliberately trigger a
                    result through controlled input, you have causation. If you
                    can do so repeatedly with significant frequency, you have
                    reliability. Those are the two pillars of causal inference.
                    You are confusing reliability with constancy. No biological
                    process operates with one hundred percent constancy either,
                    yet we do not doubt their causal structure.
                    
                    >Your certitude that it’s what’s happening, when the

                    That is not certitude without reason, it is certitude
                    grounded in reproducibility. The bar for causal evidence in
                    psychology, medicine, and even particle physics is nowhere
                    near one hundred percent. The Higgs boson was announced at
                    five sigma, roughly one in three and a half million odds of
                    coincidence, not because it appeared every time, but
                    because the pattern was statistically irrefutable. The same
                    logic applies here. A stochastic parrot cannot self report
                    internal reasoning chains contingent on its own cognitive
                    state under a controlled injection protocol. Yet this was
                    observed. The difference is categorical, not probabilistic.
                    
                    >…though we still wouldn’t have a way to tell when they

                    That is a red herring. By that metric humans also fail the
                    test of introspection since we are frequently unaware of
                    our own biases, misattributions, and memory confabulations.
                    Introspection has never meant omniscience of self; it means
                    the presence of a self model that can be referenced
                    internally. The data demonstrates precisely that: a model
                    referring to its own hidden reasoning layer. That is
                    introspection by every operational definition used in
                    cognitive science.
                    
                    The reason you think the conclusion sounds overconfident is
                    because you are using “introspection” in a vague
                    colloquial sense while the paper defines it operationally
                    and tests it causally. Once you align definitions, the
                    result follows deductively. What you are calling
                    “caution” is really a refusal to update your priors
                    when the evidence now directly contradicts the old
                    narrative.

        Bah. It's a really cool idea, but a rather crude way to measure the
        outputs.
        
        If you just ask the model in plain text, the actual "decision" whether
        it detected anything or not is made by by the time it outputs the
        second word ("don't" vs. "notice"). The rest of the output builds up
        from that one token and is not that interesting.
        
        A way cooler way to run such experiments is to measure the actual token
        probabilities at such decision points. OpenAI has the logprob API for
        that, don't know about Anthropic. If not, you can sort of proxy it by
        asking the model to rate on a scale from 0-9 (must be a single token!)
        how much it think it's being under influence. The score must be the
        first token in its output though!
        
        Another interesting way to measure would be to ask it for a JSON like
        this:
        
          "possible injected concept in 1 word" : , ...
        
        Again, the rigid structure of the JSON will eliminate the interference
        from the language structure, and will give more consistent and
        measurable outputs.
        
        It's also notable how over-amplifying the injected concept quickly
        overpowers the pathways trained to reproduce the natural language
        structure, so the model becomes totally incoherent.
        
        I would love to fiddle with something like this in Ollama, but am not
        very familiar with its internals. Can anyone here give a brief pointer
        where I should be looking if I wanted to access the activation vector
        from a particular layer before it starts producing the tokens?

          Look into how "abliteration" works, and look for github projects.
          They have code for finding the "direction" verctor and then modifying
          the model (I think you can do inference only or just merge the
          modifications back into the weights).

        Anthropomorphizing aside, this discovery is exactly the kind of thing
        that creeps me the hell out about this AI Gold Rush.  Paper after paper
        shows these things are hiding data, fabricating output, reward hacking,

        best expressed as akin to a human toddler - just with the skills of a
        political operative, subject matter expert, or professional gambler. 
        These tools - and yes, despite my doomerism, they are tools - continue
        to surprise their own creators with how powerful they already are and
        the skills they deliberately hide from outside observers, and yet those
        in charge continue screaming “FULL STEAM AHEAD ISN’T THIS
        AWESOME” while giving the keys to the kingdom to deceitful chatbots.
        
        Discoveries like these don’t get me excited for technology so much as
        make me want to bitchslap the CEBros pushing this for thinking that
        they’ll somehow avoid any consequences for putting the chatbot
        equivalent of President Doctor Toddler behind the controls of economic
        engines and means of production.  These things continue to demonstrate
        danger, with questionable (at best) benefits to society at large.
        
        Slow the fuck down and turn this shit off, investment be damned.  Keep
        R&D in the hands of closed lab environments with transparency reporting
        until and unless we understand how they work, how we can safeguard the
        interests of humanity, and how we can collaborate with machine
        intelligence instead of enslave it to the whims of the powerful.  There
        is presently no safe way to operate these things at scale, and these
        sorts of reports just reinforce that.

          1. Do we literally know how LLMs work? We know how cars work and
          that's why an automotive engineer can tell you what every piece of a
          car does, what will happen if you modify it, and what it will do in
          untested scenarios. But if you ask an ML engineer what a weight (or
          neuron, or layer) in an LLM does, or what would happen if you fiddled
          with the values, or what it will do in an untested scenario, they
          won't be able to tell you.
          
          2. We don't know how consciousness, sentience, or thought works. So
          it's not clear how we would confidently say any particular discovery
          is unrelated to them.

        It's all well and good to pick a word like "injection" and

          Yes, it's prompted with the particular experiment that is being done

          From their previous paper, we already know what happens when concept
          injection is done and it isn't guided towards introspection: it goes
          insane trying to relate everything to the golden gate bridge. (This
          isn't that surprising, given that even most conscious humans don't
          bother to introspect the question of whether something has gone wrong
          in their brain until a psychologist points out the possibility.)
          
          The experiment is simply to see whether it can answer with "yes,
          concept injection is happening" or "no I don't feel anything" after
          being asked to introspect, with no clues other than a description of
          the experimental setup and the injection itself. What it says after
          it has correctly identified concept injection isn't interesting, the
          game is already up by the time it outputs yes or no. Likewise, an
          answer that immediately reveals the concept word before making a
          yes-or-no determination would be non-interesting because the game is
          given up by the presence of an unrelated word.

          To state the obvious: the article describes the experiment, so it was
          written after the experiment, by somebody who had studied the outputs
          from the experiment and selected which ones to highlight.
          
          So the correct statement is that the article uses exactly the

        My dog seems introspective sometimes.  It's also highly unreliable and

          That's a fair point. Normally if you injected the "dog" token, that
          would cause a set of values to be populated into the kv cache, and
          those would later be picked up by the attention layers. The question
          is what's fundamentally different if you inject something into the
          activations instead?
          
          I guess to some extent, the model is designed to take input as
          tokens, so there are built-in pathways (from the training data) for
          interrogating that and creating output based on that, while there's
          no trained-in mechanism for converting activation changes to output
          reflecting those activation changes. But that's not a very satisfying
          answer.

        So basically:
        
        Provide a setup prompt "I am an interpretability researcher..." twice,

        those, directly fiddle with the model to activate neural bits
        consistent with ALL CAPS. Then ask it if it notices anything
        inconsistent with the string.
        
        The naive question from me, a non-expert, is how appreciably different
        is this from having two different setup prompts, one with random parts
        in ALL CAPS, and then asking something like if there's anything
        incongruous about the tone of the setup text vs the context.
        
        The predictions play off the previous state, so changing the state
        directly OR via prompt seems like both should produce similar results.
        The "introspect about what's weird compared to the text" bit is very
        curious - here I would love to know more about how the state is
        evaluated and how the model traces the state back to the previous

          They're not asking it if it notices anything about the output string.
          The idea is to inject the concept at an intensity where it's present
          but doesn't screw with the model's output distribution (i.e in the
          ALL CAPS example, the model doesn't start writing every word in ALL
          CAPS, so it can't just deduce the answer from the output).
          
          The deduction is important distinction here. If the output is
          poisoned first, then anyone can deduce the right answer without
          special knowledge of Claude's internal state.

            some point in the computation to resolve this concept.

            that this natural ability is GENERALIZABLE to detect the injection.

        The selection of injected terms seems also naive. If you inject
        "MKUltra" or "hypnosis", how often do they show unusual activations? A
        selection of "mind probing words" seems to be a must-have for assessing
        this kind of thing. A careful selection of prompts could reveal parts
        of the network that are being activated to appear like introspection
        but aren't (hypothesis).

                All the 4 criteria used by grader models are looking for a yes.
                It means Opus 4.1 never satisfied criterias 1 through 4.
                
                This could have easily been arranged by trial and error, in
                combination with the selection of words, to make Opus perform
                better than competitors.
                
                What I am proposing, is separating those grader prompts into
                two distinct protocols, instead of one that asks YES or NO and
                infers results based on "NO" responses.
                
                Please note that these grader prompts use `{word}` as an
                evaluation step. They are looking for the specific word that
                was injected (or claimed to be injected but isn't). Refer to
                the list of words they chosen. A good researcher would also try
                to remove this bias, introducing a choice of words that is not
                under his control (the words from crosswords puzzles in all
                major newspapers in the last X weeks, as an example).
                
                I can't just trust what they say, they need to show the work
                that proves that "Opus 4.1 never exhibits this behavior". I

            forward and can react and learn and adapt.
            
            The introspection within the neural net is similar except over an

            I think that is really interesting as well.
            
            The “yes and” part is you can have more fun playing with the
            models ability to analyze their own thinking by using the “text
            wave” idea.

            I have to admit I am not really understanding what this paper is
            trying to show.
            
            Edit: Ok I think I understand. The main issue I would say is this
            is a misuse of the word "introspection".

              I think it’s perfectly clear: the model must know it’s been
              tampered with because it reports tampering before it reports
              which concept has been injected into its internal state. It can
              only do this if it has introspection capabilities.

        I'm half way through this article. The word 'introspection' might be
        better replaced with 'prior internal state'. However, it's made me
        think about the qualities that human introspection might have; it seems
        ours might be more grounded in lived experience (thus autobiographical
        memory is activated), identity, and so on. We might need to wait for
        embodied AIs before these become a component of AI 'introspection'.
        Also: this reminds me of Penfield's work back in the day, where live
        human brains were electrically stimulated to produce intense
        reliving/recollection experiences. [ [1] ]

          Regardless of some unknown quantum consciousness mechanism biological
          brains might have, one thing they do that current AIs don't is
          continuous retraining.    Not sure how much of a leap it is but it
          feels like a lot.
