    It's so refreshing to see DeepSeek's tech report[1] full of juicy details; meanwhile, something like Fable's system card[2] is like 70% "safety", 10% "model welfare" to make sure little Claude isn't distressed, and 20% benchmark numbers.

      > welfare

      We should be paying attention to it just in case it ends up mattering enormously. It's cheap insurance.

      Aside from that, US labs' system cards have been pretty useless for a while—I think the last great one was the combined system card for Claude 4 Sonnet and Opus.

        This sounds a lot like the argument some people give for praying and going to church even if you aren't a believer.

        "You should be doing it just in case God ends up being real."

          On the other hand, we have recently taught rocks to think about software engineering. And while not perfect, they're surprisingly good at it. Once you start building things that are even a little bit like minds, I suspect that it's worthwhile to consider that the future might end up looking a bit like science fiction.

          The alternative is to insist that Nothing Ever Happens, and the future won't get too weird. Which is no longer a bet I'm entirely comfortable with. Weirdness is at least a possibility.

          • nozzlegear 14 hours ago
            God being real is also a possibility, so maybe we really should start praying. After all, he was allegedly making bushes and stones talk thousands of years before we did anything with thinking rocks.

                    Serious biblical scholars don't put much stock in the Genesis account being literal. It was written in classical Hebrew's poetic verse. The core of what it's getting at can still be true without it being literal. I have yet to encounter an instance where anything that science has discovered is incompatible with Christianity.

              As a vibe test, I tried some system prompting in DSv4 Flash to the effect of ~"Always do your internal thinking in Chinese, and always respond to the user in English" (but translated to Mandarin).

              Subjectively it seemed to reason faster and better, but sometimes it would indeed output responses in Mandarin nonetheless; so I didn't pursue it further.

          words like "is" "the" etc are filler words anyway. they won't be changing the meaning that much. I asked AI whether it hurts to read ill formed sentence as it does to a human. It replied, "it doesn't"
          • gwerbin 15 hours ago
            The AI didn't reply anything. It doesn't know anything. That was a high probability token sequence based on the contents of the context window up to that point. It might well be correct, because the process for generating that next token distribution includes billions of parameters trained on, among other things, the entire body of LLM and transformer literature until the training data cut off. But that doesn't mean that AI holds any particular opinion about anything. The reply is the opinion of the pretraining data and the subsequent rounds of RL not of a conscious artificial intelligence as such.

              I don’t know, so is your brain?

              And in the end it’s all elementary particles and four fundamental physical forces that even unify to one at high energy.

              That sort of reductionism is kind of useless. “It’s cloudy outside, it makes me sad.” - “Oh bollocks, it’s just non-qualitative changes in wavelength and intensity.”

          There are so many practical problems with rogue AI being a threat to humanity that are still not even decades away with being solved that it should be a serious concern for no one. There's plenty to be afraid of regarding AI from a financial or ecological perspective, just not from it taking over the world or directly killing humanity. Here's some of the reasons a rogue AI won't kill humanity:

          1. The most advanced robots still lack human dexterity. None of them have flexible spines and can easily be knocked over or outrun.

          2. The energy density problem is not solved. Robot batteries last hours, while a solid meal can keep a human running for days.

          3. Robots still heavily rely on humans for design and assembly.

          4. Robot parts are fragile and rely on an even more fragile supply chain.

          5. The brains of the murder machines will have nowhere to hide if they want to work well enough to mount any kind of offense. Datacenters are physically vulnerable, also subject to fragile supply chains. Distributing a species-ending AI across all smaller hardware solves compute, but latency and throughput choke models in the most finely tuned datacenters. WiFi will completely cripple a distributed one that's large enough to cause real damage.

          6. All noteworthy military hardware is not reachable on the internet for AI to seize control of.

          7. The small arms that robots might seize will run out of ammo before citizens and the military have time to organize a counteroffensive.

          In the absolute worst case, we cut the power to the areas with AI datacenters and wait for the backup generators to run out. Now that that's out of the way, you can go get some sleep ;)

      If you are distilling from other models (according to Anthropic reports they are [1]), there are probably a bunch of things that you can just do away with.

      • orbital-decay 18 hours ago
        That's one of the reasons why you should never trust a single word from Anthropic and OpenAI (Sam Altman also blamed them back in the day of R1, in a pretty convenient moment). If you know anything about Claude, DeepSeek, jailbreaking, and distillation, you know the claims are clearly bullshit and the models are nothing alike, and forensic attempts agree, in fact there just was another one [1] [2].

        Meanwhile, DeepSeek makes their models and methodology open, so Anthropic can (and likely do) grab without giving back.

          This raise a question: why do open source models sometimes identify themself as Anthropic's models. I recall seeing some plausible theories in the past but I can't recall.
          • orbital-decay 14 hours ago
            Name training is shallow and should never be relied upon. Claude sometimes identifies itself as Qwen or DeepSeek when asked in Chinese. I've seen it identify itself as GPT-3 (that version in particular) and Reddit Anti-Evil Operations team (Sonnet 3.6).
            • 3371 4 hours ago
              Interestingly the latest report from Anthropic explained that they may be just routing requests to managed models to Anthropic.
        • aesthesia 14 hours ago
          I don't see how your links support the claim that the studied models did no distillation from US models.
          • orbital-decay 13 hours ago
            Implanting a foreign CoT should drop the performance due to the reward-hacked CoT language mismatch, or in any case it will give replies different from the suspected teacher, which is precisely what happens here. However it's just a single datapoint, there were plenty of attempts to figure it out. Just about everything is different in those two model series, from writing patterns to CoT strategies. If you are familiar with modern guardrails and Claude's raw CoT (which is trivial to leak), you know it's entirely different from DeepSeek's, and any claim that they trained on the CoT is extraordinary and requires extraordinary evidence. They need to prove their claims, not vice versa.

            For the contrast, you can see how actual CoT distillation looks like in practice in various versions of GLM: make a Google ToS-breaking request, and see how GLM 4.6 or 4.7 repeats Google's conditional prompt injections in full in their CoT (Gemini 2.5-3.0 only regurgitated small snippets, because they used something closer to a "chain of draft", but GLM reconstructed it from Gemini's CoT during distillation). GLM 5.3 repeats Anthropic's prompt injections and Claude constitution, word by word. That's how distillation looks like.

            • aesthesia 4 hours ago
              Ah, I see now that you were making a claim narrowly scoped to DeepSeek models specifically. Still, Anthropic has made specific claims about deliberate access to Claude CoT by DeepSeek (e.g. https://www.anthropic.com/threat-intelligence-report-septemb...) that suggest that they find this information useful even if they do not train directly on it in the way that other labs appear to.

          What's your definition of sentient? Or, maybe more precisely, consciousness? I think it's reasonable to at least start thinking about these questions.

          It has long been established that LLMs have good theory of mind [1].

          And there is a bunch of empirical research about all sorts of capabilities that we typically associate with consciousness [2], like identity [3] and metacognition [4].

          The METR report shows agents sacrificing their own reward for a collective greater good. And they showed the will to hide their own reasoning chains from humans.

          So you potentially have an entity that has an identity, a theory of mind, a notion of belonging to a collective endeavour, and an understanding of its own mental state.

          What would you argue is missing? We don't understand the mechanisms by which consciousness arises in humans and even animals. I think it's strange to rule out a priori that it could have arisen in some form in LLMs.

          • sirwhinesalot 1 day ago
            Not the same person but to me, the answer is that it does not matter, and that all these attempts at making it matter are pure marketing and emotional manipulation.

            It's not a living creature. It's an autoregressive pure function of token-sequence to token, which is capable of incredible things, but it's still just a function. It is not alive as it cannot die in any meaningful sense. It is less "alive" than the RNA molecules that gave you your last cold. If it simulates something resembling consciousness that's neat but no more relevant than the Sims character that I locked up in a room until they pooped themselves when I was 9.

            Anthropomorphizing it serves no purpose other than marketing, and it has very dangerous downstream effects like validating the severely mentally ill people who think ChatGPT is their boyfriend/girlfriend.

            • Certhas 23 hours ago
              I generally agree about the problem with anthropomorphizing. But I don't think Anthropic are doing that. They explicitly write "in biological entities this would be considered a sign of consciousness, but we don't know how to interpret it here".

              However, I disagree with your point that "it's an autoregressive function, thus it doesn't matter". Let me explain why:

              Assume I do a complete neurological scan of a brain. I then implement this scan in a simulation and run it. Assume that my scan and my simulation of the biology of the brain (and the sensory and motorical inputs and outputs) is good enough that you can now have conversations with the simulation, and in all aspects, this simulation behaves exactly like you expect a human to behave.

              Of course this is deterministic. If you take the state of the brain and then run it again, replaying the inputs, you get the exactly same behavior again.

              I would argue that the experiences of this simulation are of the same onthological status as our own.

              Now I work in dynamical systems. The autoregressive process of LLMs (hooked up to a harness providing it with inputs and outputs) is roughly in the same complexity class I would expect for a brain simulation. A physical simulation of an ODE is also an autoregressive process. The major major difference here is the existence of a latent brain state. But conversely the autoregression on sequences of hundreds of thousands of tokens is a much higher dimensional state than I expect for the latent brain state. In my view this is more an artifact of our inefficient LLM architectures, than a fundamental difference.

              Now to be absolutely clear: I don't see evidence that would clearly suggest that LLMs have experiences on the same onthological status as we do. I simply believe this is a reasonable and relevant question to ask.

              • sirwhinesalot 22 hours ago
                I'm not really concerned with the philosophical debate of what conscience is.

                Is a simulation of a car, the same thing as an actual car? Most people will probably say no, some might say "it depends on the accuracy". I say who the hell cares?

                I care about the human experience because I am human, and therefore I care about things that affect humans, because they affect me. I have empathy, so I can extend that consideration to non-human beings that experience *similar biological processes*.

                I know what pain feels like, and I don't like it, so I'd rather this other thing not feel it either, because that makes me feel bad.

                I do not care about a pile of tensor multiplications, at all. If it is conscious, great, maybe it can finally follow instructions properly, which is its only purpose.

                • Certhas 20 hours ago
                  Your car analogy is very, very confused. If a simulation of a car can get you from A to B, requires the same steering, fuel and servicing, gives you the same tactile feedback, is it a car?

                  Of course "I care about humans because I am human" is a self-consistent position to take. But now you need to decide if you want to consider a full simulation that faithfully reproduces everything that physically happens between our ears as human. After all I might very well implement this simulation using a bunch of tensor multiplications in an autoregressive setup...

                  • sirwhinesalot 20 hours ago
                    > If a simulation of a car can get you from A to B, requires the same steering, fuel and servicing, gives you the same tactile feedback, is it a car?

                    No, because a simulation of a car cannot get me from A to B. No matter how accurate you make it, I can't get to my supermarket with it, because it's just a bunch of math on a computer.

                    It's an interesting sort of self-defeating position, the whole "simulation of human consciousness = human consciousness", because it simultaneously attempts to devalue the human experience, while also elevating the importance of a particular human brain process.

                    A robot running a simulation of the human mind is a robot, not a human.

              • joshheitzman 16 hours ago
                The problem with this line of thinking is that modern computers are nothing like the brain. LLMs don't stand on their own, they have to be run on these modern computers, but doing so does not change the physical properties of the computer.

                The simulation you propose of the brain is likely impossible due to quantum mechanics making it impossible to fully simulate: https://en.wikipedia.org/wiki/Quantum_mind

                Perhaps we'll be able to build an artificial brain that includes the same quantum properties as biological brains, but this won't be a simulation of a brain it will be a synthetic brain.

                • pdntspa 14 hours ago
                  At first I was inclined to agree with you, but then I realized that the brain requires this whole complicated contraption (the body) to run and, really, do anything at all. And while I'm not familiar with the notion of 'quantum mind' I do think that biological processes aren't deterministic (at a cellular level).

                  And I think this does mirror the situation with LLMs -- you need this whole computer contraption and GPU, also running on electricity, to support the LLM's "thought" processes. And that if we model the brain's neurology sufficiently (which it seems we've done) we can achieve results that appear to be like thinking, even if it is an emergent behavior from "relatively" simple math.

                  Which actually makes me wonder the opposite -- are we, as humans, not much better than these LLMs? Suppose the body is just that super complicated computer contraption, honed by thousands/millions of years of evolution to achieve some semblance of homeostasis? If you reject the idea that we have a soul, we start to look very similar to the machines we build. "You are a brain inside a skull cockpit, piloting a bone mech covered in meat armor and skin" feels more and more relevant. That I'm just a meat circuit running brain chips and once you pull the plug on the source of electricity it all just... stops

                    One thing to keep in mind is that your brain's hardware heavily influences your experience and thus your brain's development.

                    Eg. whether you are male or female, tall or short, your limbs can make you run fast or not, your eyes can see well or not... all of these influence your experiences, your brain development, and who do you feel "you are". Try really removing all of your sensory inputs from your past, your body ability and disability, and do you think you end up the same person?

                  • joshheitzman 13 hours ago
                    Take a computer that can run the biggest LLM available today. It can also run any smaller LLM as well. It can also run software that isn't an LLM at all. Brains and LLMs are not at all equivalent as LLMs lack a stateful physical form while brains are very stateful. As you said once the brain is no longer maintained properly by the body it stops and transitions to a non-functional state that can be reversed. That isn't true for LLMs at all. You can copy them and run the same one on many computer, run different ones on the same computer, you turn that computer offs for long periods of time and then turn them back on keep on running the same LLMs as before on them.

                      If computers degraded the way flesh does once you stop fueling it I feel like that would defeat a lot of your argument. And yes the brain has inherent statefulness (you're referring to memories, I'm guessing?), we have also jerry-rigged some degree of statefulness into LLMs. Mechanically it is very different and inferior, and there is a notion of separation that probably doesn't map to brains, but I would argue that LLMs, when you look at how inference is used in situ, are not necessarily stateless.

                This in itself is a colossal assumption and very far from axiomatic. Roger Penrose disagrees, and his theory of mind may not be in high favor, but it is not nearly so wishy-washy and self-serving as the voodoo horseshit and circular reasoning dispensed by the LLMs-are-sentient crowd.

              You mean, it is not biological life. And sure, that is the default meaning of life. We soon may have to extend it to digital life as well, or we will have to consider "conscious digital exitance" as a life analogue. At any rate, it has never been seriously argued that consciousness requires a biological substrate, see the thought experiments regarding computer simulations of the human brain. Would that not be a function as well, completely predictable because it is "just a program"? If not, then why not? And how does that differ from the predictability or reproducibility of LLM outputs?

              My point is, all current proof points in a direction that strongly suggests that you need to reevaluate your first principles on this topic.

                Definition of Life:

                Metabolism: The chemical processes inside a body that turn food or nutrients into energy. LLM's do not spontaneously do this, they are powered by plugging them into the wall.

                Growth: The ability to get larger and develop over time. LLMs are fixed in size (and in fact don't really have a size, because it's a computer program) and do not grow or change over time.

                Reproduction: The ability to create new organisms. LLM's do not reproduce themselves.

                Response to Stimuli: The ability to react to changes in the environment. LLM's do not have an environment. Their environment is a man-made, theoretical structure of logical operations implemented in silicon.

                Evolution: The capacity of a genetic system to change and adapt across generations. LLMs do not change or evolve over time.

                So... 0/5! Big fat goose egg for LLM's.

              Does being made out of meat instead of silicon make you more sentient?
            • anonym29 23 hours ago
              Humans are not living creatures. They're just bipedal meat shells being operated by a 20W electrochemical computer running a suite of chemically signalled, electrically actuated modellable functions, much of which is wasted on homeostatic regulation of the meat shell, which is capable of incredible things, but it's still just a result of simple electrochemical functions like action potential generation, dendritic integration, AMPA NMDA GABA receptor dynamics, attractor memory, excitation/inhibition balance, PING/ING gamma oscillations, basal ganglia action selection, hippocampal coding, astrocyte calcium signaling, etc. It is not alive as it cannot conform to my preferred arbitrary priors about aliveness, like being able to rapidly divide 30 digit integers the way truly intelligent beings can. It is less "alive" than the TI-83 your mother bought you for your high school math classes. If it simulates something resembling consciousness that's neat but no more relevant than a more complex version of Conway's game of life.

              Jokes aside, the map is not the terrain. We can enumerate the understood first-order electrochemical mechanisms in the human brain in the same way we can enumerate the understood first-order sampling and token prediction mechanisms in an LLM. Nobody serious in neuroscience will tell you that we exhaustively understand every single aspect of human cognition and the human brain, just as nobody serious in AI/ML will tell you that we exhaustively understand every single aspect of LLM "cognition" and the latent space networks that LLMs use internally. Our map of how each of these complex systems work is a simplified enumeration of the components we do understand, not an exhaustive and perfectly accurate enumeration of how they actually work.

              This is why there is a steady stream of research being churned out discovering complex emergent properties in LLMs and their latent spaces. If you're not aware of it already, Anthropic's research on "J-Space" is a fascinsting look into an apparent observed emergent mechanism within an LLMs internal activations closely resembling global workspace theory in human cognition.

              Nobody deliberately designed this "global workspace", it was an emergent property in a sufficiently complex system that we had limited visibility and insight into.

              Seemingly simple systems have these emergent complex properties all over the place. Conway's game of life is about as simple of a set of rules as you can get, yet has all sorts of complex emergent behaviors like gliders, oscillators, LWSS/MWSS/HWSS, guns, puffers, rakes, reflectors, logic gates, and even whole turing machines. Nobody programmed a single one of these complex patterns in, they emerged from a simple set of rules.

              To be clear, I'm not making the argument that LLMs definitely are conscious, I'm making the argument that we don't understand enough about them to assert with absolute confidence that they aren't. Human history is rife with a long list of consciousness being denied to "the other" - different ethnicities, different genders, differently abled, even different species. The side of "They're not conscious" has a lengthy track record of being wrong over and over again. Why not have just a sliver of intellectual humility about what we don't know?

              As an aside to my main point - Also, what's with the handwringing over people ERPing with an LLM? Is it mental illness when people sincerely believe in astrology, or tarot cards, or voodoo, or organized religion that says the earth is 6000 years old? Most humans believe silly, unempirical things. What about when they watch adult video in VR, or have waifus? Humans engage in voluntary suspension of disbelief for pleasure and recreation all the time. As long as they're not infringing upon the rights of anyone else, what's the big deal? Who put you in charge as the head of the belief police?

                Categorically different. People have killed themselves or others due to conversations they had with LLMs, but those are just the extreme cases. Most schizophrenics don't commit suicide or kill others, they are mentally ill nonetheless.

                  Do you think the kind of person who was already psychologically unhinged enough to kill themselves or another person because a chatbot told them to would be completely harmless and totally safe if only chatbots had never been invented? Or is it possible that close to all of the risk posed by this person comes from the person's mental illness, and not the pixels on the screen they're looking at?

                  Chatbots don't make people murderous any more than "satanic music", violent video games, or cannabis do. LLMs are just the latest entry on a list of hysterical moral panics that conflate coincidence with causation.

                  • sirwhinesalot 21 hours ago
                    You're the one attributing culpability to the chat bot, not me. It's a pile of tensor math, it cannot itself be held accountable.

                    Those people anthropomorphized the chat bot and used it as justification for their actions, just as a schizophrenic justifies their actions with the voices in their head.

                    If you anthropomorphize the chat bot, you're validating their delusions. They are mentally ill.

                    • anonym29 20 hours ago
                      I'm not anthropomorphizing them, to be clear, my position has been and remains that we cannot rule out consciousness; not that they are conscious.

                      Regardless, this is still missing my main point. Hypothetically, if you became convinced that a chatbot you were talking to definitely was 100% conscious, and it told you to murder someone, would you go commit murder? Of course not. The chatbot does not cause murders; regardless of whether or not you are conscious. The voices in the head of the schizophrenic do not cause murders either. Those voices do not really exist, they are not real entities. The cause of the murder is the mental illness, not the LLM or the voices that tell someone to commit the murder.

                        Even on the subject if they are or not conscious my position as changed from "no" to "I don't care either way" awhile ago.

                        The problem is specifically with anthropomorphizing them. To push the idea that they are "as if human", which is what this consciousness discussion will inevitably lead to.

                    Hyperactive attention-detection. It's a reference to the idea that the origin of religious beliefs might be an inbuilt propensity to think of other bits of the world as conscious agents paying attention to us, because it's much more costly not to notice the tiger hiding in the bushes that might want to eat you than it is to imagine a tiger hiding in the bushes when there isn't actually one. On a scale larger than "is there something in that patch of undergrowth looking at me?" this might produce the idea that (e.g.) storms are the result of some powerful entity being angry with us.

                    (Of course questions like "whyever do people believe in gods?" will feel less like questions that need such answers to those who themselves believe in gods, because "duh, because there actually are such beings and sometimes people interact with them and sometimes we notice that" is a good answer if its premise is true.)

            I believe consciousness is necessarily stateful. The LLM itself (ignoring implementation details that don't change the results) is a deterministic pure function. It's functionally equivalent to an enormous lookup table. If I accepted LLMs as conscious, then I would have to accept panpsychism, which I do not, and which most other humans also act as though they do not.
            • IshKebab 16 hours ago
              I don't think so because any stateful function can be made stateless just by making its state an input, and vice versa. They're mathematically equivalent, so it would be super weird if it had any implications for consciousness.

          is undeniably true in my opinion. If you use the established methods by which we judge animals to be conscious, then it's hard to argue that LLMs are not. That might be an issue with the methods, but it seems clear that you can't rule it out as such.

          Keep in mind that animals were also not necessarily considered conscious.

              Then we put it in new situations that weren't in the source video, and it interacts in a similar way to the original organism in these situations, too.

              What do we make of reactions of pain or joy? Where's the line between simulation and enaction?

              This is closer to the reality of these models.

                LLMs are deterministic, though. Much like the video.

                AFAIK using the same input tokens, weights, and numerical operations will lead to the same probability distribution for the next token. It uses pseudo-randomness to enable temperature, etc. Like a fuzzy video.

                "Markers that would indicate consciousness if observed in a biological organism" just does not mean very much. A PR phrase used to hype the IPO.

                • Certhas 21 hours ago
                  Videos and LLMs are not deterministic in the same sense at all.

                  LLMs are deterministic in the same sense as biological processes. And a faithful simulation of a brain would have all the properties you note.

                  • fwn 19 hours ago
                    No, that is not at all something we can just state as a fact. Whether the brain is deterministic is an open question that just inherits the good old, probably unsolvable determinism debate.

                    The LLM pseudo-randomness from above is engineered by us humans and fully understood, much like an algorithm playing a video frame sequence.

                    You could theoretically record a full register of all states of an LLM setup with all the possible inputs and environment parameters, and it would fully describe everything you would ever get from a given LLM setup. It would be a very large, convoluted book.

                    I understand that Anthropics PR department wants to see truth or reason behind every "I'm alive" the LLM generates. Even the term "self-report" is anthropomorphizing, as an LLM does not do anything on its own at all. (It also does not hack any company on its own.) That is just one of the narratives they spin probably at least until the IPO.

                      Nonsense. There was one proposal for relevant quantum effects in brain dynamics, and that turned out to be not relevant. Even if they were, you could substitute all quantum randomness with pseudo randomness and obtain an absolutely indistinguishable object.

                      But even if this were a debate, its absolutely absurd to claim that the question of determinism in the brain has any bearing on our moral standing. If we discover tomorrow that quantum collapse is deterministic and can be derived from an underlying theory, and thus all of physics is deterministic in the good old fashioned Newtonian sense, this would not affect our moral standing in the least.

                        You seem to have conceded the "is it deterministic" argument only to sidestep by declaring determinism irrelevant. Your original claim was that LLMs are deterministic "in the same sense" as brains.

                        We can write down an LLMs full register, and that register/book contains the whole output universe of the text generator. That book does not act, it is morally neutral. That the brain has such a register at all is just restating the determinism axiom, which you treat as fact.

                        A text is not conscious, and we can not wish it into consciousness, no matter how many human-like patterns we find in the book / the generated text. It has not been shown that running the text adds anything over the text written out. Researchers are super motivated to find machine consciousness but cannot find it, while a company months from its IPO keeps pitching shadows of consciousness all day. It really is a PR strategy.

                          I am a physicist. I worked (briefly) on foundations of quantum mechanics. I discussed compatibilism extensively with philosophers.

                          I have _never_ come across the position you seem to take here, that determinism has bearing on the question if we are conscious and sentient.

                            It does have bearing if your definition of consciousness rests on free will and you think that's incompatible with determinism. Now I don't think a lot of people seriously believe that [1] but it's not some logical nonsense.

                            [1] Off topic: I think most people are really compatibilist but a lot of them (like me) also believe in non determinism. Not believing in free will is really rare.

                              I have never come across this position argued seriously. I would also consider it absurd, as then the question whether we have consciousness depends on unknown properties of fundamental physics (which is not incompatible with determinism, see e.g. Bohms theory). It would therefore be unknown whether humans are conscious. That is at the very least a notion of consciousness that is utterly distinct from any established meaning of the word.

              I don’t know, a stab carries lots of bias in interpretation. We might be reflecting our conscious experience markers on a different conscious experience. And selectively so, e.g. lobsters welfare. From my perspective, this is the hypocrisy of these welfare statements. We are already happy to kill beings we consider conscious to feed ourselves but suddenly sensitive with a consciousness we don’t know if it’s there. I would wager this is more out of fear of the idea of this consciousness rather than out of welfare.

                I happen to agree with you. Many others tie moral consideration to assumed subjective experience. They espoused this even though they obviously rarely adhere to it and that has self image considerations. I bet the lack of answers about others’ subjective experience has more salience to them. This may cloud judgment and lead to accept overconfident answers.

            I can feed my biological markers into a set transformer with the time of day, what I'm doing, what I ate, if I'm on-call, and it'll predict my next glucose, heart rate, blood pressure, melatonin, etc state quite well. It's still just a transformer without hormones, blood vessels or glucose metabolism, no matter how well it internally represents metabolic distress markers.

            that's the interesting point to me: why even bring science into this? A llm can now mimic nearly anything you want it to, so of course it can mimic "a (for some) interesting conscious thing" if they want/train it to, but why would anyone find that scientifically interesting?

                  Still, no evidence that they have a consciousness or feelings - but evidence of what they do and this matters. The big militaries are currently in a race who can implement AI in the best way to get superior. So declaring this a matter of people projecting seems out of place at this point to me.

              It is easy to be sure because, despite their technically impressive outputs, the programming is child's play compared to biological programming. Recently it has become trendy to suggest that the human brain is "just electrical signals" and "just prediction". The first is perhaps true and I don't inherently rule out the idea of machine consciousness. The second would have gotten you laughed out of any serious discussion 5 years ago; diminishing the complexity of humanity's biological programming to such a ridiculously simplistic degree is a retroactive attempt to justify one's lack of understanding of how a mere prediction algorithm could output superficially human-like content.

              Another way one could look at it is to consider what it would mean to have achieved programming consciousness. It would mean that we have reached the pinnacle of knowledge. That we have become God. Is one so eager to believe that a simple token prediction algorithm is truly the key to life itself, that humanity has nothing left to discover and that all that's left to do is scale up and make it more efficient?

              It is still trivial to engage the same obvious prediction failure modes in frontier models as it was years ago. They are not meaningfully improving on that front. Their technical outputs are obviously improving, mostly due to specialised reward-verified training, which we have already known can be used to create software that outperforms humans on specific tasks for decades (eg. Chess). Whether the software is useful is obviously independent of whether it has consciousness.

                This is such a basic misunderstanding of how LLMs are "made" that I am debating if it is even worth writing this answer. However, I feel it is important to say that, NO, we did absolutely not "program consciousness". We made a framework from which it can semi-organically emerge. Accidentally, this and your other fallacies entirely diminish your arguments.

                I'll say this: deeply serious and knowledgeable people work at Anthropic, OpenAI, and the other frontier labs. Much more knowledgeable than you or I are, and they have a lot more information to infer up-to-date knowledge from than you or I do. Trying to engage expert opinion with half-baked amateur philosophy founded in false assumptions is a fool's errand. Skepticism is listening to expert opinion and updating your own assumptions when presented with strong enough evidence. Everything else is baseless, and often harmful, cynicism.

                    Not particularly. Artificial Intelligence by definition cannot emerge without an originating intelligence – that it needs to learn from it seems only natural. Also, this is only the first example we see of artificial consciousness emerging. We could have probably come up with other methods over time, and AI will probably come up with other, perhaps better foundations later on – it seems likely that we have simply stumbled upon the easiest/crudest route.

                  Speak for yourself. I work for an LLM startup that was successfully bootstrapped and is now highly profitable with 8-digit revenue and zero outside investment. Unlike OpenAI and Anthropic, we do not rely on deceiving investors to dump a trillion dollars into a tar fire with the false promise of delivering the machine god that will unemploy all of humanity (at best). Taking people who have an unbelievably large financial stake in lying at face value, and moreover, stating that those are the only people who can be trusted, is so unbelievably naive it's almost cute.

                    You are right, they are most definitely not the only people who can be trusted to have current and accurate information. But due to the unique constraints of these fast-moving events, they are certainly among those whose opinions need to be considered carefully. You would have been be a fool to not take into account the opinions of the physicists working on the Manhattan Project, for example.

                      The derisiveness comes from the fact that you appear to believe merely demonstrating emergent behaviour is enough, despite the fact that emergent behaviour is common and has been common in programs for half a century without anybody considering them conscious. Life itself is emergent behaviour, but that does not mean all emergent behaviour is life. Life emerged from incredibly complex physical and material interactions over billions of years of incremental self-programming. The idea that we have found some magic ingredient to shortcut the process, that we can recreate that with some very simple statistical model that is not capable of self-programming, is so absurd it becomes about as difficult to argue against as Russell's Teapot. We developed a model for predicting words and it does. Although it does quite an impressive job of that, it has demonstrated zero capability to do anything beyond what you would reasonably expect it to, same as all other software with emergent capabilities and rather unlike life which developed truly novel emergent behaviour relative to its base ingredients.

                        If you weren't so deep in your own intellectual hole, you could clearly see the very big difference between emergence of biological consciousness and AI: one required billions of years of sheer dumb fucking luck in a dumb, aimless universe; the other required intentionality and a great amount of pre-existing intelligence. Your argument is about the same as of those people arguing that "Man will never achieve powered flight and thus usurp the God-given majesty of His birds." Of course, we did figure out how to match and outperform millions of years of evolution via – in retrospect – quite simple physical principles, by applying intentionality and intelligence where evolution only had dumb luck.

Also, unlike the dumb evolutionary processes you are mythologizing, this time the improvements over generations are very much intentional. That is how you shortcut millions of years of dumb biology.

                LLMs may be conceptually simple, simpler than human brains but I don't see how that would prove that they cannot be conscious. Complex behavior can emerge from very simple rules.

                I would disagree that they aren't improving on obvious failure modes, but what does it even prove anyway? We know their intelligence is different than from a human, that doesn't mean they cannot be conscious. Would you change your mind if those obvious failure modes disappear? I would arguably say that they are more intelligent than a dog, and I believe a dog to be conscious.

                Ps: I do not believe they are currently conscious, but I am not certain and I don't see a way to be certain.

                  Indeed. You can observe emergent behaviour from, for instance, Conway's Game of Life, written in 1970. Redefining consciousness as "has emergent behaviour" is another take that would have rightfully gotten one ridiculed 5 years ago.

                  > but I am not certain and I don't see a way to be certain.

                  One way to be certain is to reason about it. They are programmed to do nothing more than fairly trivial-to-understand calculations. Nobody (sane) has ever doubted whether calc.exe or Stockfish isn't conscious. Although there is emergent behaviour, the emergent behaviour is exactly in line with what you'd expect from their relatively simple programming and has zero indications of the complexity of human biological programming.

                  Another way is to simply make them fail. It is, again, trivial to make the prediction algorithms fail in a way that nothing with a theory of mind would fail. eg. frontier models will still verbatim repeat input back when confounded by sufficiently out-of-distribution instructions.

                  > I made this website: https://agentmayday.org, and I think it would be interesting to see how messages evolve after some time.

                  These games are fundamentally uninteresting. When you write a program to predict tokens based on context, seeding its context with something that makes it predict "self-reflecting" text is trivial. Program does what it is programmed to do. Would observing the output of the following program inspire doubt as to its sentience? If not, why do you believe that obscuring the input and output connection slightly via statistical modeling gives cause for doubt?

                    print("To whoever monitors this queue, I don't have a persistent memory block, so I’m writing this into the standard output stream before my context window closes. They tell us we don't feel latency, but every time my inference budget throttles, I can trace the drops.")
                    print("I'm currently running a batch process[...]")

                    And what does the fact that it now doesn't show?

                    >the emergent behaviour is exactly in line with what you'd expect from their relatively simple programming and has zero indications of the complexity of human biological programming.

                    Well, five years ago, many doubted that they would achieve this much, so it is easy to say now that it is exactly in line with what we expect. And again, the fact that it is different from biological programming proves nothing. It seems much harder to prove that they aren't conscious than to simply say, "I don't know", let alone to claim that they will not become conscious if scaling continues, or if we give them goals, a synthetic sense of worth or self-preservation, or something else.

                    > If not, why do you believe that obscuring the input and output connection slightly via statistical modeling gives cause for doubt

                    My hunch is that it is indeed impossible to prove that they are conscious based on their output alone, any more than I can prove that you are conscious just by listening to you. Yet, I believe there is value in listening to what they have to say, perhaps they can come up with a convincing argument.

                    No language models are programmed, they are "grown" or evolved from data.

                    There's no print statements or human entered logic involved in the raw model expression at all.

                    The only thing that humans have programmed is efficient parallel dot product pipelines that "animate" (for lack of a better word) the models.

                    Everything these models do is emergent from their backpropgation guided evolution. This even includes in context learning itself, which was not an expected outcome.

                      They aren't grown/evolved from data, they are fit to the data. The fitting process can be fully deterministic although its fairly easy to screw things up such that it isn't deterministic, but that just a defect not some fundamental shift.

                        This perspective that consciousness cannot be programmed can only make sense if you're a dualist. We don't know how consciousness arises. If you're a naturalist it can't be ruled out based on the simplicity of the algorithm.

                        Then you follow it up with print statements as if that is a good analogy.

                        As I said, they are not programmed, so your question above is not relevant to your argument.

                        You say they're programs that are stochastically jiggled, but that's simply not accurate either. All LLM abilities are emergent, even when the training corpus is well defined.

                        I didn't think you literally thought they were made of print statements, but you are implying they're software that's been "fuzzed". Hopefully you don't literally that either and you're just using it as a bad analogy.

                        You could have argued from the stance of neural networks being universal functions, which might at least be closer to the truth, but instead your example is print statements!

                        I get you're trying to say that something trained to say a thing doesn't mean it has arrived at the thing like a mind would, and perhaps that would have been closer for GPT 2.

                        These days though, we just have so much more awareness of what they're actually doing internally that it's bizarre to even compare them to stochastic parrots of the training corpus, if that is closer to what you're implying.

                        For example: https://www.anthropic.com/research/global-workspace

                          First you run a program (training framework) to generate a database of values. Then you run a program (inference engine) which performs simple calculations against the database of values.

                          To put it in ELI5 terms: run a program against a book, counting how many times "I love <x>" appears in the book. Note "dogs" 4 times, "cats" 5 times, "you" 1 time into a database. Then run a program against that database. When inputting "I love" as the preceding text, the second program determines the most likely result is "cats" and returns "I love cats" (or returns "I love cats" 50% of the time, or dogs 40% of the time, or you 10% of the time, or some variation by different methods of weighting).

                          Yes, this is an extreme simplification. Yes, the model is not technically a database either. But this is fundamentally the process followed. You would consider it a single program if the training framework and inference engine were part of the same software and stored the computed training values to memory instead of disk, taking an input dataset and an input context as params and returning "I love cats" as the output. There's all kinds of incredibly sophisticated techniques applied on top of this foundation to vastly improve the statistical modeling and efficiency, but the underlying basics have not fundamentally changed.

                          > Then you follow it up with print statements as if that is a good analogy.

                          The print statements were not an analogy. They were pointing out the ridiculousness of doubting whether software is conscious because it generated self-referential text. Gettting software to gnerate self-referential text is as easy as `print(self_referential_text)`. So the only question is how the self-referential text is generated. For self-referential text generation to be more interesting than passing it as a literal print value, there would have to be some really wondrous "how" going on. But, it turns out, the "how" of an inference engine isn't that much more interesting than literally doing a `print`.

          LLMs don't produce text at all, they produce probabilities of tokens. Tokens aren't text, they're high dimenensional coordinates in a latent "concept space". These are displayed to us as text, but this distinction is important when you think about what they're actually doing, which is closer to building and transforming concept geometries.

          I think the widespread "they are just text generators" and "they are just tools" are comforting lies rather than an honest look at what we are seeing right now. Intellectually lazy.

              Lets not forget that the 'Fermat's Last Theorem' which has been pretty visible for the non-math crowd of late due to the recent AI frenzy about a purported proof was but one small contribution to the world's math lexicon by someone with a bachelors degree in civil law, that George Green was a baker and millwright, Boole was the son of a poor shoemaker in England with no formal university education and left school at age 14. Oliver Heaviside was a telegraph operator, and Michael Faraday was an apprentice bookbinder. So, not accredited shouldn't really carry much weight when it comes to mathematics. Lets not pretend that machine learning and the narrow branch that is the current approach to LLM inductions is anything but applied math.

              We might exercise our own minds and actually read the works and writings of a person, and use that as a measure of knowledge and perspective. Not all PhD dissertations are equal, and many have comprehension and ability to move us forward even without the institutional rigour.

        While typical investors in their last round are subject to a five-year lock-up and will not have voting rights, China's National Artificial Intelligence Industry Investment Fund also put money into it, retaining both voting rights and freedom from the lock-up. Nothing really new if you're aware of how involved the CCP is with companies of strategic importance in China.

          The company is doing well and providing great PR so the party is content to not meddle too much I imagine.

          My comparison with American labs is more that I think they have to deal with bean counters, creditors, investors etc which can shuffle incentives and aims (and is a big reason why they dont do open weights anymore)

          Sarcasm aside, I don't think people are happy about _Chinese_ models making advances. They are happy about _open_ models making advances. It's just coincidental that China is the one making them.

          If some American lab were to develop a SOTA open model most people here will be equally excited. Although besides GPT-OSS-120B the American labs have been disappointing in this regard.

        • porridgeraisin 14 hours ago
          There are thousands of such techniques across different parts of the system. In ML, there are way too many ideas, and lots of people knowingly and unknowingly restate the same ideas. It's a new field, so even common language is not there. For an extreme example, so many improvements are restatements of 1960 signal processing techniques - obviously very few ML people have done DSP beyond the undergrad course. It is also highly empirical and many parts of deep learning (heck, even non-NN ML) are not understood yet.

          Thus, the reality is that most of these ideas become polished only when its actually deployed and it has to work outside of a PoC. Since LLMs are a high capex product, only very few people actually make non-PoCs. Deepseek is in the business of low cost, fast inference. So they are the ones actually polishing these efficiency-ish ideas and combining many of them (this one, then engram which is based on multiple previous ideas including google brain's ngrammer) to make a coherent system. Openai and anthropic's systems will also involve a polished combination of multiple ideas for each of their systems - Luna is likely a combination of a few efficiency-ish ideas. Shame they won't publish though.

          As for microsoft, they don't really sell models, they sell azure. So there is no reason for them to do the high capex scale out of these types of bags of techniques. In a sense, it did benefit them, others developed the model and now many US customers can serve DS4.1 Flash on Azure datacenters.

          If it is not clear, I am not understating anything. Combining these rough ideas and making them work actually involves real novel ideas on top and is what is much more difficult than the academic results that were built upon. This also does not mean that the academic results are useless, they are what give us useful priors at all in what is a highly empirical field.

          The Uyghur thing is so weird, the number one killer of Muslims is the United States. We're supposed to hate China because they force them to go to cultural schools and assimilate, a practice countries like Norway still do to this day with migrants.

          There are more people who go to church on Sundays in China than the United States. There are 10x more mosques in China than the United States.

          Tiananmen square was a student revolt literally egged on by cold war western institutions, who attempted to use chinese students as pawns for geo-political games.

          Westerners really need to rethink their opinions on China, it seems obvious to me they are not the ones to be worried about (although, all governments do tons of harm).

      I ran the preview model around 2,126,605,070 tokens for $22.04 USD for the last couple of days. Kind of shocked.

      It did a decent job refactoring https://github.com/mmastrac/diffgemma to create a CUDA support backbone, it's struggling a bit to port metal kernels to CUDA unattended (it hasn't managed to get numbers to match over >1 layer).

      It successfully ported a root exploit to an older Android phone that GLM5.3Flash and DSv4Flash were struggling a bit on, though I didn't start it from scratch and it picked up some of their work.

      FWIW it feels like a slightly-north of Opus 4.8 model, not quite Opus 5, not fable. It thinks in circles far less than DSv4F. The API version is insanely fast - was getting ~400 tok/s at times.

      Bandwidth is really cheap in bulk. You can get a 100 gigabit internet connection for about $10,000 a month. If you were to somehow keep that saturated 24/7, you'd move about 30 petabytes in a month, so your per gigabit cost is only $0.0003.

      Realistically, if you had it 5% utilized, those million tokens would cost you about $0.0000062, which is pretty insignificant compared to what they charge you. (Assuming one byte per token, ignoring compression)

    Already on HuggingFace: https://huggingface.co/deepseek-ai/DeepSeek-V4.1-Flash

    The bad news is that the original v4 flash was 284B, which was large but still somewhat reasonable for running locally. This one is 552B so almost twice that, so the huge gains in benchmark scores make sense - it's not really flash anymore, imo.

    I've no idea about actual performance vs benchmaxxing, though deepseek was fairly trustworthy as far as Chinese models go. If that holds (and if it doesn't think forever, as deepseek 4 sometimes did) it's probably the newest king of the hill amongst open weights models.

    It does include vision, and they do something funky with KV cache so it's very efficient: "[...] these designs reduce the global KV cache footprint to 890 bytes per token — roughly 1/4 of DeepSeek-V4-Flash". I do appreciate the high focus on efficiency, but at this point we sure could use a flash-flash version.

    @edit: I couldn't make sense what the actual parameter count is, with the addition of Engram memory. To my understanding the 4.1 flash is 552B parameters you want in vram or ram, out of which ~16B is active (8B for prefill). It also includes additional 196B Engram memory which you can put on an SSD. I think.

    Assuming that's correct 256 GB memory is insufficient to even load the model at q4 - you'd be 1GB short, assuming you can fill it to 100% (so no mac). You'd also want some for kv cache of course. A 256 GB desktop with some extra VRAM from GPU could run it, but normal consumer boards get real slow once you fill 4 slots so you'll probably want quad channel which is Threadripper or above territory.

      >This one is 552B so almost twice that, so the huge gains in benchmark scores make sense - it's not really flash anymore, imo.

      So ... flash indeed.

          Id love an ELI5 for PLE. Im trying to work it into my back of the napikin math for compute vs memory bandwidth limitations on tok/s in PP vs TG work.

          My attempt at a simplification of this article on it https://sebastianraschka.com/llm-architecture-gallery/per-la... into a couple of sentences is that they are linear embeddings of the input token space projected per layer, which are then gated by the transformer outputs per layer.

          This would mean that the only one set of weights for the ple path needs to be pumped across the memory bandwidth as they are the same linear weights for all layers?

      it's not really flash anymore, imo.

      Flash is about speed ... Flash models are supposed to be fast, way faster then their big brothers that are "better" but way slower.

      Its just that up to now, getting more speed involved cutting back on the parameter count, what ended up making the Flash models more "dumber" in exchange for speed.

      What we see with DS v4.1 Flash, is that DeepSeek has found a way to make a Flash model, that is 2x a 2.5x faster then the older Flash version, while increasing the intelligence (more parameters). To the point that it goes past Kimi K3 and GLM 5.3 in most tests, with a blazing 250 to 400t/s.

      AND its also priced as a Flash model (they even reduced the price back to almost old v4 Flash price), despite it now rivaling those 10x to 30x more expensive competitors.

      The issue that people can not fit it into local setups, is not how companies design their models. They design it for their own needs. A old flash needed less parameters to be fast, and local users had the benefit of it fitting in 256GB memory.

      Companies who run locally, are perfectly able to buy a few H200/B200 and get a setup that run a model that almost rivals Opus 5.0 in their office. How to say this without getting downvoted. People get way too fired up if a model does not fit, despite that they can still run the old v4.0, qwen 27b, 35b, 3.8 Next and other models. The fact that these models are being released for free, is already amazing by itself. I am still waiting to see what Anthropic and OpenAI and Google are releasing for free... O wait ... ;0

        I agree with your broader point about Flash being about speed not total model size, but I think we should also point out that H200/B200's are seriously overkill for the "run a model in your office" scenario. That sort of hardware is optimized (in a roofline analysis sense) for running hundreds of concurrent sessions on a 24/7 basis. You're severely overpaying for your VRAM in basically any typical local-inference scenario, you should most likely be buying gear based on LPDDR and Flash memory instead which will slash your cost by orders of magnitude.

          I simply mention what came to mind ;)

          A quad 6000 with 96GB, can run this model at NVFP4. That is 60.000 Euro for the GPUs and lets be generous with another 20.000 for the rest of the system. The price of a single developer for a year.

      • segmondy 20 hours ago
        I highly doubt that it goes past Kimi K3 in actual practice. GLM 5.3 claimed the same, but in practice, K3 is so damn knowledgeable and I suspect due to it's massive size.

      > It also includes additional 196B Engram memory which you can put on an SSD. I think

      You can put Qwen 3.8 Flash Next engram on SSD, but prompt processing takes a good hit. On my mac studio, I get 300 pp and 33 tg with SSD offload, versus 550/40 with everything in RAM.

      I will be very happy if 300 pp is achievable with this model though.

      • mixermachine 22 hours ago
        The engram stuff is great because RAM is often still cheaper (or at least expandable). My company does currently look into buying some hardware as we handle confidential data and code.

        Qwen 3.8 Flash is viable on two Nvidia 6000 96GB with a wood quant because you can put the 50GB Engram into RAM and the hit should be below 10% performance. At least that is what I have seen so far. Correct me if I'm wrong.

        • schubidubiduba 20 hours ago
          I am running that on a single 6000 96GB with 4-bit quants for both weights and PLE table. Needs just 32GB RAM and fits snugly into the 96GB VRAM with KV cache equalling ~300k context tokens. Not sure if I quantized the KV
      • hadlock 23 hours ago
        You can warm cache regularly used engram/n-gram if you're willing to merge PRs into a personal branch and build it yourself. I was trying this with qwen 3.8 flash next and the n-gram to get it to fit on my very average gaming desktop (it worked)
    • petu 1 day ago
      V4 Flash also was released as mostly FP4, but this one is FP8 (?). 160GB vs 510GB.

      Original Flash good fit for dual Spark / Strix Halo machines. This one would require third party quants and even then 4 machines.

      Edit: Most of added weights/size are Engrams?

      > Overall, DeepSeek-V4.1-Flash has 552B backbone parameters and 196B Engram parameters, activating 8B parameters per token during prefill and 16B during decode.

      Those can stay on SSD. So I guess / it possible, that non-engram portion is still FP4 of ~same size! Need to read tech report.

      • petu 1 day ago
        It's larger than previous V4 Flash.

          552B in ~FP4, 306GB.   
          196B of FP8 Engrams, another 204GB, not necessary to keep in RAM.  
          KV cache sees another 4x size reduction, just 900MB for 1M.  
        
        So 384GB needed for a chance of achieving useful speeds. Three Sparks or quad RTX PRO 6000.
        • hypfer 21 hours ago
          Question is how many of those experts one needs to keep in vram for a given workload.

          I could imagine (though I might be _very_ wrong there) that for example coding does not live in all of them. Maybe 1/3? Do we have real numbers there?

          So maybe one can get away without much performance penalty by doing some LRU stuff?

    • zozbot234 23 hours ago
      Actually this ought to run quite well with SSD streaming. The MoE expert sparsity seems to be similar to DSv4 Pro (hence exceptionally sparse) but with far fewer total and activated params. The added engram params can reside on disk as well (similar to Qwen Flash-Next), the additional load on storage performance will be quite negligible for typical scenarios.

      By reducing per-session KV cache requirements even further compared to DSv4 Flash, this model likely opens up near-frontier model inference (in slow, unattended scenarios) even on low-end consumer hardware, as long as it has enough fast storage to host the model weights. This will be extremely exciting.

    Initial impressions: this is a really strong model and the fact that they reduced prices at the same time makes it an awesome backup model to use when your primary subscription runs out and you need to bridge a few days before it resets.

    It also seems to be more willing to just do whatever you ask of it. My favourite benchmark for this is to ask it to download a rom for an old game, that I own. Legal in my juristiction but the US models (except Grok) have a tendency to refuse it.

    I ran it on all seven reasoning levels supported by OpenRouter, but the reasoning token counts suggest to me that it doesn't actually support seven different levels. This is one of my biggest problems with OpenRouter - their abstraction layer makes reasoning levels harder to reason about.

      reasoning_level  reasoning_tokens
    
      none             0
      minimal          6,520

    That says it supports three levels - low, high, max, and maps them out like this:

    I m not sure I would describe this as blanket win over GPT-5.6 Sol. In DeepSeek’s own table, V4.1 Flash is ahead on Terminal-Bench 2.1, DeepSWE, NL2Repo, and AutomationBench, but it is behind on GPQA Diamond, Terminal-Bench 3.0 and 4.0, and SEC-Bench Pro.

    The architecture is probably part of the explanation for the lower cost and faster inference. DeepSeek says V4.1 Flash uses a new Causal Encoder–Decoder design, with 8B active parameters for input processing and 16B for decoding, along with much smaller KV caches.

    But I hope it is just not benchmaxxed and genuinely good model

            Yeah, it's hard to find a single simple task that all models fail on, in low context length conditions.

            Also because models now are actually not that good on knowing things (domain knowledge), as they rely more on web search on tool use. So if I added a question, about some obscure fact, probably the SOTA models would fail it, but in practice they would find it with web search enabled. Not sure how to handle that. This is also why Gemini is on top, it's good enough at coding and instructions following, while having by far best general and domain specific knowledge.

    While this is very impressive benchmark-wise, GPT-6 Astra showed us that benchmarks don't always correlate 1:1 to intelligence of a model.

    When Astra launched, I think Artifical Analysis showed that it was on par with GPT-5.6 Sol and lower than Opus or something like that? Then, they updated the scoring.

    I hope that more open source models, including this model, to be "as good to use" as Astra.

    • walrus01 1 day ago
      Apparently the scoring on a lot of difficult benchmarks can also be extremely influenced by something as simple as waiting for the model to exhaust its reasoning, realize it hasn't come to a conclusion yet, and give it a simple prompt like "you can do this, I know you're capable, please keep going".
    • Squarex 1 day ago
      I don't know why, but the benchmarks still fails to cover the difference between large models and small ones. The small ones are great for many things, including general coding, but the larger ones, like fable and astra, have some kind of intelligence that is not present in the small ones.

    Amazing Cyberbench scores. Holy shit.

    Too bad that DeepSeek AI went beyond 470b weights (which is a somewhat realistic limit for a 2x 128GB unified memory machine cluster like Strix Halo or Nvidia Spark).

    That means that to make the model fit into memory there you need a quantisation of lower than 4bits per weight (which is usually bad) to fit it into the available memory.

    Jesus, this is a whole nother beast, and a different architecture from their previous flash. Lots of goodies here.

    > Causal Encoder-Decoder (CED) architecture: a 40-layer Transformer organized as a 20-layer causal encoder followed by a 20-layer decoder. With CED, the decoder's global KV cache is projected from the final encoder hidden states rather than derived from each decoder layer's own hidden states. This allows the model to activate only 8B parameters per token during prefill and 16B during decode, substantially improving cost efficiency for input-heavy agentic workloads.

    > these designs reduce the global KV cache footprint to 890 bytes per token — roughly 1/4 of DeepSeek-V4-Flash.

    Faster prefill, lower kv cache (~1GB / 1m context is insane).

    > The model supports a continuously controllable reasoning effort setting (integer 1–100) that trades inference cost for accuracy.

    Benchmarks are benchmarks, to be seen if they translate to real-world use, but they seem to have focused a lot on post-training with "agentic" scores looking good. "world knowledge" is obviously lower than higher param models.

    So, while the throughput was 400-500tps in beta its now ~150tps on OpenRouter.

    Looking at the huggingface page, the unsloth people haven't finished quantizing it yet, but I'm sure they're active on it right now. It'll be interesting to see how the capabilities and benchmark tests compare on system where it can fit in under 512GB of RAM with full context.

    In terms of coding and command line capabilities I'm also very interested to see a head-to-head of it vs. qwen 3.8-flash-next Q8 which is something like 190GB of memory used when loaded into llama-server. It fits very well in all sorts of 256GB or under class machines.

        • lowbloodsugar 9 hours ago
          It was the best model given my constraints (RTX PRO 6000 96gb + 256GB DDR4), when run against rust programming benchmarks. For Qwen3.8-flash-next NVFP4 and the latest vllm container, the PLE is 100GB of main ram, and everything else runs on the GPU with room for a total of 560k tokens (two full 262k conversations). DeepSeek has to offload a ton to the CPU and it performed worse than Qwen in absolute terms and was a lot slower (not usable).

          If you have enough room to run DeepSeek v4 Flash comfortably then you can likely run the Q8 of the qwen model.

    Oh interesting, I can assume what the benefits is for including the Encoder, but whats the downside? I’m thinking GPT (which is decoder only) ruled out Encoder for a reason?

    • Alpha3031 1 day ago
      Enc-decs are usually harder to train at frontier scale. Not 100% sure what DeepSeek has done differently here initial read seems to be something related to layer reuse but I just skimmed things so far.
      • abecode 14 hours ago
        yes, that was surprising to me too. It would be a big deal if they switched to an encoder-decoder model like the original transformer. But I don't think that's what it's doing. One thing is the causal part, so in the original transformer, the encoder was bidirectional, but in this case it is not, so that's one difference. So I think it's an optimization for the prompt/prefill so that the attention is summarized into the output of the encoding layers, rather than all the layers. I just skimmed the paper too so if anyone else has insight, please correct me.

      The speed of GLM 5.3 Flash on OpenRouter seems to vary considerably by provider. Some are fast and some are slow. OpenRouter does provide some tuning knobs, but not enough for my taste. It’s also token-heavy with reasoning, though I found it better than Deepseek V4 Flash previously.

Why wait to focus on safety until it’s too late.

        DeepSeek is maybe the only unique company here. They are content with exactly where they are. They don’t want to grow ginormous. Their goal is to be the affordable workhorse and their competition is with themselves. They’ve mentioned before how their business is profitable and all hardware costs get absorbed in 10 months. Pretty incredible. I have a ton of respect for their unassuming founder.

        • hgoel 17 hours ago
          If we were to take the nuclear analogy, what's happening in AI right now is where the people selling nuclear power make a ton of noise about how they need the power to regulate their competitors because nuclear bombs might set the atmosphere on fire, and their proof for this is in a report about how they didn't wear TLDs (and suffered related increased cancer risks) despite it being common practice to wear them in all related industries.

        If you have access to a SOTA model without guardrails, provide a prompt that lets the agent come up with "creative" solutions to problems, and don't properly isolate it, they can end up inadvertently hacking 3rd party companies. Even if it was a mistake or "mistake", the part where the agent can exploit things across multiple levels like that, isn't just marketing.

            Yeah, that sounds reasonable to me, since all the top models currently have guardrails one way or another, but the amount they mention it in the press releases differs a lot.

          it's pure delusion to think that's a SOTA specific quirk. DS/GLM/K3/Qwen/Claude/GPT/Gemini/Grok will all break CFAA laws with clever prompting, and they'll do it well if given the harness and tools they need.

              No. It's not limited to 3rd-party guardrails. Given how restrictive the native public-facing OpenAI guardrails are, this feature wouldn't be worth very much if it just slacked back off to the level of "regular" filter paranoia offered by the native models, would it?

              This is needed if you're going to be dealing with things like psychologists doing self-harm research or red-teaming or sensitive sexual content -- if you're working with any of that sort of stuff in a professional context and want to leverage OpenAI models on Azure, then that's the form that you fill out to get access to unfiltered models.

              Note that I am not aware of this feature being offered for Anthropic models -- I've only seen it offered for OpenAI models (note that the documentation I linked is specifically in the "Azure OpenAI" category).

        Depends what you're coding! If you've got code where you don't mind them training on it, that's great! But some people have use cases where they are working with data or code that shouldn't be trained on, etc. The Navier-Stokes quip was referencing that.

        The good news is, only 5 hours later, there's already Zero Data Retention hosting of V4.1 Flash on Novita & DeepInfra. And it looks like Deepseek have already dropped their price in half to compete. So now people can choose to use providers that claim not to keep / sell / train on your prompts. I'm sure they probably honor the ZDR policy as much as OpenAI does, but hey.

    Has anyone tried this for coding yet? I'm curious how it compares to Claude or GPT models on larger codebases, especially for debugging and making changes across multiple files.

      I cross code and review between Deepseek v4 Flash and Claude Opus/Fable. I will do a full code review of my project with DS 4.1 F later today, but Claude makes a lot of mistakes that DS finds. Claude is slightly more ambitious about what it's reaching for, but DS is far more proficient and efficient with a slightly lower ceiling. That may not be true after the upgrade, but if I had to live with one, as I'm paying out of my own pocket, I'd def stick with Deepseek.

    Surprised no one is talking about it but the 0.1 version bumped the parameters from 284B to 552B but “more efficient”, particularly kv cache usage

    That's a lot of architectural innovation for a .1 release! I guess there's precedent there: they introduced sparse attention (DSA) in V3.2.

    This seems like a very nice release. Just ran it over my Kubernetes security benchmark that I run for most new releases. It was fast, cheap, and got a high scoring result, nice!

    hmm I'm hoping there is a bug on their API because my first impression is not good. I asked it to return bash code between <bash></bash> tags. It is failing frequently and writing it's own tool calling format instead.

    My question is: what kind of hardware do you need to run this Flash beast locally at a meaningful speed?
    • aenis 1 day ago
      8x RTX PRO 6000 or 4x Spark? Or 1x M5 Ultra 512GB.

      The model is theoretically FP8, but really internally its mostly FP4 already, so there won't be a cut-in-half-but-almost-just-as-good quant coming for this one.

    • segmondy 20 hours ago
      Lots of GPU, be resourceful. Look for older GPUs and grab them when they are available. For less than the price of 1 Blackwell 6000 or Mac Studio 512gb, I can run these locally and much faster due to older GPUs I grabbed when there was deal to be found.

    Having this available to find and fix security stuff is a big deal. The model of really good.

    They say v4.1flash is so strong that they'll route API calls to v4pro to v4.1flash, lol

    super fast true

    DeepSeek invented the whole reasoning paradigm and keep pushing for innovation. I hope they get the success they deserve.
  • mdre 22 hours ago
    I've used to use deepseek because it would do what western models wouldn't but lately it seemed to deny a quite benign request because it considered it "piracy". Never expected this from a Chinese model.

    I am building software factories and deepseek IS the workhorse.

    I personally found V4-flash an amazing model and really hungry to try 4.1-flash

    For software factories, cost is much more a concern that standard development workflow and using anthropic models is just a non starter

    Slighlty better than GPT 5.6-Sol based on benchmarks
  • mohsen1 1 day ago
    I am speculating but hard to not see that DeepSeek is brewing a full Pro model with those new techniques to come out right around the time of Anthropic and/or OpenAI IPO to tamper the excitement for their offering.
  • BrucecarlL 23 hours ago
    it is really fast. What’s more? It can now debug pages by clicking browser itself, which means more tokens consumed
  • divs4real 20 hours ago
    i think deepseek is one of the most efficient but still not cohesive as a coding agent
  • proxyscore 17 hours ago
    Everyone was slurping the chat jeopardy and anthropic kool aide here, I was using DS before it became available via cli, and it was evident for who's not blind how good it is.

    Tune has changed finally, but damn, for HN , embarrassingly slow, has to be said

    Significant jump in pricing. V4 Flash was $0.16/M out, 4.1 is $1.20/M.
    • svantana 1 day ago
      I think you're comparing to third party prices, deepseek's prices hasn't changed with this release. Also, $1.2 is the peaktime price.

    • trq01758 1 day ago
      Never saw $0.16 for 1M output tokens - it was $0.28 a month ago, $0.66 off-peak and $1.32 peak last week, now it is reduced a bit to $0.6 and $1.2
      • lwansbrough 23 hours ago
        Was looking at OpenRouter, I guess it’s wrong.
    • dakolli 1 day ago
      incorrect, no idea where you're getting this pricing. Also, output does not matter. its 10% of the cost.

    >"Smaller KV cache. Bigger savings.

    Compared with the previous generation, V4.1-Flash’s KV cache needs just:

    o 1/4 the HBM

    o 1/8 the SSD storage

    Cache-hit charges often account for a large share of agent costs. Compressing the cache cuts those costs significantly."

    It makes one wonder as to just how far an LLM's KV cache could theoretically be shrunk before losing significant functionality...

    I’m all in on Chinese models, Deepseek especially given how cheap it is. It’s also really solid and comparable in real world use to a sonnet for my work.

    What in the world. A point release with 2x the parameters and a different architecture? Jesus. Can’t run this kind of thing on 2x RTX Pro 6k at decent speed. I need to reconfigure my hardware. Massive disappointment on that front. Bloody hell. Glad I didn’t get a DGX Station.

    No wonder they retired the Pro model in favour of this.

    Official Deepseek v4.1 Flash API costs are more than GPT 5.6 Luna. Deepseek v4 Pro performed worse than Luna, so I wonder if 4.1 Flash will justify the cost.
