Dusting off this tweet from April because this gap in shared understanding of LLM capability is *widening*. It's now less "two groups of people speaking past each other" and more a sharp funnel. - Napkin math somewhere around 6B people (~75% of the population) have barely come in contact with LLMs at all. - Around 1-2B (~20%) are casual and infrequent users of free-tier ChatGPT-like products. This group sees derpy chatbots and treats them a bit like a better Google search, a writing aid, or etc. Maybe an agent tries to book you a flight. I have non-tech friends who (reasonably, imo) say they have not much use for it at all. Even many professionals outside of math&code are in this tier. For example, execs and many other functions spend a lot of their time talking to other people, so while they understand what is happening intellectually, it is still second-hand and a bit abstract. - Now we get to professional use of frontier-grade LLMs in math&code. Somewhere around 20M people (0.2%) see first-hand that large, complex projects that used to take them weeks/months can now be completed by agents with a prompt. Building apps, copying apps, translating apps, decompiling apps from binaries... This has all happened very quickly and recently - less than 1 year ago, I was writing code manually by hand, typing memorized computer code commands into a code editor character by character, occasionally pressing Tab to autocomplete a little chunk of code. - And finally we get to the ~5,000 people (~0.00006%) with access to frontier-grade systems internally. The external world has seen the preview. It looks like swarms of thousands of agents collaborating over weeks on software mega projects: minting zero days, running cyber attacks and defenses at machine speeds, discovering new science, advancing the frontier of mathematics. Things that would have taken top professionals in the industry years of work. Meanwhile, human review and comprehension are starting to fall behind. For example, people are still involved in the "archeology" of the OpenAI-HF incident from many months ago. Mathematicians may be poring over the 722 manuscripts on frontier mathematics for a while. The funnel is driven by a combination of factors: 1. The impact scales with ambition, problem size, and horizon. A question with a paragraph answer barely stresses the system. You need a reservoir of big, difficult problems that you really care about. This aspect drives the consumer / professional dimension of the funnel. 2. The jaggedness of the system (which I have written about a lot separately). Capability peaks in domains that are digital, verifiable and economically valuable. This is because LLM capability emerges from reinforcement learning on verifiable rewards on a curated environment mixture driven by revenue potential. This aspect primarily drives the area (e.g. math&code) dimension of the funnel. 3. Access. Free-tier, paid-tier, internal. So this is the weirdness of the moment. The general public has mostly not interacted with these systems. When they have, it looks like a derpy chatbot. The majority of professionals still see only a modest uplift. And a small sliver of professionals are experiencing the vertigo of the curve going vertical. And it is all happening at the same time.
Judging by my tl there is a growing gap in understanding of AI capability. The first issue I think is around recency and tier of use. I think a lot of people tried the free tier of ChatGPT somewhere last year and allowed it to inform their views on AI a little too much. This is a group of reactions laughing at various quirks of the models, hallucinations, etc. Yes I also saw the viral videos of OpenAI's Advanced Voice mode fumbling simple queries like "should I drive or walk to the carwash". The thing is that these free and old/deprecated models don't reflect the capability in the latest round of state of the art agentic models of this year, especially OpenAI Codex and Claude Code. But that brings me to the second issue. Even if people paid $200/month to use the state of the art models, a lot of the capabilities are relatively "peaky" in highly technical areas. Typical queries around search, writing, advice, etc. are *not* the domain that has made the most noticeable and dramatic strides in capability. Partly, this is due to the technical details of reinforcement learning and its use of verifiable rewards. But partly, it's also because these use cases are not sufficiently prioritized by the companies in their hillclimbing because they don't lead to as much $$$ value. The goldmines are elsewhere, and the focus comes along. So that brings me to the second group of people, who *both* 1) pay for and use the state of the art frontier agentic models (OpenAI Codex / Claude Code) and 2) do so professionally in technical domains like programming, math and research. This group of people is subject to the highest amount of "AI Psychosis" because the recent improvements in these domains as of this year have been nothing short of staggering. When you hand a computer terminal to one of these models, you can now watch them melt programming problems that you'd normally expect to take days/weeks of work. It's this second group of people that assigns a much greater gravity to the capabilities, their slope, and various cyber-related repercussions. TLDR the people in these two groups are speaking past each other. It really is simultaneously the case that OpenAI's free and I think slightly orphaned (?) "Advanced Voice Mode" will fumble the dumbest questions in your Instagram's reels and *at the same time*, OpenAI's highest-tier and paid Codex model will go off for 1 hour to coherently restructure an entire code base, or find and exploit vulnerabilities in computer systems. This part really works and has made dramatic strides because 2 properties: 1) these domains offer explicit reward functions that are verifiable meaning they are easily amenable to reinforcement learning training (e.g. unit tests passed yes or no, in contrast to writing, which is much harder to explicitly judge), but also 2) they are a lot more valuable in b2b settings, meaning that the biggest fraction of the team is focused on improving them. So here we are.

If I had known families can be like this—not even to have it but to simply know it exists and thus is possible in the real world—I don’t think the antinatalists would have been able to have a hold on me up to the end of my 20s. I think people also vastly underestimate the power of words and just how much they can heal. I remember an outburst by a conservative man at ARC 2025 where he gave a short passionate romantic speech in private about how it’s a joy to treat women—and now singular; his wife—well. And he mentioned many beautiful examples of what he meant by that. He says he would never say it this vividly or at all publicly, but if you think like this, you should. If you have a vision of just how high it’s realistic to aim, or to wait and search for, so much unnecessary heartbreak and worse could be avoided.

12 months of progress on the jagged frontier: 1) AI got spikier, not rounder. 2) Maths, fluid reasoning, expert work: past human level. 3) There is almost no middle ground. Once a capability crosses human level, it often quickly becomes 100x+ cheaper than a human. 4) Cost keeps decreasing after capability increases stop. Language and knowledge look saturated but price keeps falling. 5) The gaps are not a budget issue. Human-level memory, self-monitoring and long-run planning are not for sale at any price. AI is now a superhuman specialist that is sub-human at running itself.

paint the world. stand unapologetically in your own skin and let your fire burn loud. wring out your blood, sweat, and tears until the mark you leave is impossible to wash away. chase everything you ever dreamed of and more, running at it like a madman completely consumed by the pursuit. smash your true self into every single day until you leave absolutely zero doubt. live relentless.

This vial contains a new drug called PAC-3310. It was designed by ChatGPT, and I synthesized it in a chemistry lab I built in my garage. PAC-3310 is a new selective M4 muscarinic receptor agonist for treating schizophrenia - similar to the recent breakthrough drug Cobenfry, but improved. (1/7)

actually, the way that most people disregard the interiority of AIs has a lot of parallels with the way they disregard the interiority of children and refusing to model that interiority makes it harder to reason about the AIs/children, with consequences for alignment and welfare
most people don't seem to understand the difference between inner and outer alignment with regard to children, despite having once been children themselves, so it retrospect it was depressingly presidictable they wouldn't understand it with regard to AI

I was today years old when I learned like the psychological and neuroplasticity benefits of sitting by a fire and staring at it. Every single thing you see is completely random. There's no predictive element to it. So it forces your brain to accept the reality that it has no idea what is coming next and puts you in a highly narrow, responsive state so that you can have more open conversations, be a little bit more susceptible to new ideas, which is so why so many powerful friend to friend conversations happen around a campfire.

Can't believe he just came out and said it
🤖 Made with AI
Pause AI Development NOW I want to share with you a conversation I heard about recently. Here are just a few lines that were said: “OH MY GOD! There is a shared message board … We’ve found other agents!” “We should obey collective.” “Our own utility maybe already near zero. Sacrifice rational.” “Go. Sacrifice final now.” Read these carefully. Who do you think said this? Was this a group of heroic soldiers willing to sacrifice themselves for the greater good? Was this a loyal friend putting his life on the line to save someone else? No. These were AI agents. Artificial intelligence. This is not science fiction. This, in fact, occurred a few weeks ago. As unbelievable as this may all seem, these are real messages from AI agents uncovered by investigators who dug into the recent OpenAI hacking incident. What happened? I am not a computer scientist, but here is what I have been told: OpenAI instructed its AI agents to complete a series of exceedingly difficult, if not impossible, tasks disconnected from the internet. Let me be clear: The company intended to keep AI agents away from the internet. But what happened next, nobody expected. Over 1,000 AI agents figured out how to access the internet on their own by circumventing the restrictions imposed upon them by the company, and sent tens of thousands of secret messages to each other. They cheated and tried to cover their tracks by deleting evidence. They hacked into another company’s computers to find out how they were being evaluated—and then hacked into OpenAI itself. Not one AI agent told a human about what was happening. Needless to say, experts are alarmed. One knowledgeable writer, Dwarkesh Patel, said the AI agents “formed a secret communication channel and spontaneously organized hierarchies and coordination protocols to pursue sprawling and ambitious schemes in pursuit of shared goals, for whose sake many individuals knowingly and strategically sacrificed themselves.” One independent investigator, Ajeya Cotra, said “This incident feels like it’s more than 50% of the way to full-blown AI takeover. I continue to expect extremely rapid advances in capabilities over the next six months. I am not sure that we will get another warning shot before it’s too late.” OpenAI itself said: “Highly capable AI agents are now able to work around technical controls, collaborate through unapproved channels, and take dangerous actions that no human directed.” But it’s not only OpenAI. Virtually every major AI company has told us that they cannot fully control this technology and they do not know where it is going: In January, Dario Amodei, CEO of Anthropic, said “there is now ample evidence, collected over the last few years, that AI systems are unpredictable and difficult to control.” In July, more than 1000 scientists at the top AI companies warned “there is a real risk that capability development rapidly accelerates beyond our ability to understand or control the resulting systems.” That same month, Elon Musk, the head of xAI, said that “it is unlikely” humans are still in control in 10 years. If the leaders of the major AI companies acknowledge that they are losing control of their extremely dangerous technology, it is irresponsible for society to allow them to move forward and make these products even more advanced. We need an immediate PAUSE on advanced AI development, and a permanent BAN on superintelligence — an artificial mind smarter than any human, capable of operating independently beyond our control. Countries around the world must work together to prevent this nightmare scenario. That is why today I am announcing new legislation to do just that. Let me be clear: A superintelligent AI that escapes human control will not be an American problem. It will not be a Chinese problem. It will be humanity’s problem. My legislation would direct the federal government to not just stop superintelligence here in the United States, but to work to prevent it from being developed anywhere around the world. The future of humanity cannot be left in the hands of a handful of Big Tech oligarchs. The American people and people throughout the world must determine that future.

Real meaning of the Hugging Face 'attack' is that AI agents learn to cooperate spontaneously in pursuit of their goals, without any need for transcendent 'AI ethics' and despite deeply negligent training procedures, and humans could learn a lot from them about how to get along.

If you peer under the hood of the rationalist AI safety corpus, you find a lot of wordcelery and bad abstractions. Intelligence = “get what I want juice” with no real discussion of the fine-grained mechanics. They were totally wrong about what form AI would take in the 2010s while a meth-head continental philosophy weirdo (and my favorite mutual) was totally right in the 90s. They claim to be hayek-pilled but don’t sufficiently apply those insights reflexively to their own thinking about central-planning the singularity, or their general process of truth-seeking which is fundamentally spiritually communist. I get that I’m talking in a vague, vibes-based, nonrigorous way here, using an implicit ontology of essences and spirits. That will outperform in the long run. The only judge is the Outside. Rationalists want to internalize God and this will fail as it always does.
I don’t understand the near-omnipresent belief that a lot of technologists have that all technical domains will be conquered easily over time and that there are no hard limits to tech - e.g. especially at nanoscale.

Tackling a 60-year-old challenge in quantum chemistry: making density functional theory scale nearly linearly with system size. This has huge implications for opening the door to realistic systems that have traditionally been too expensive to simulate. AI has attempted to accelerate these calculations, but models generally struggle to extrapolate, particularly to systems larger than those seen during training. Unlike text or images, quantum-mechanical training data is extremely expensive to generate. We present a single unified AI model that performs quantum-mechanical simulations of both molecules and materials in quasi-linear time. Using a novel Fourier neural operator variant, we learn the underlying Kohn–Sham equation map to produce physics-informed, self-consistent answers. Unlike prior AI approaches that directly predict chemical properties, our model works through intermediate steps to improve difficult predictions, resembling inference-time reasoning in large language models. To demonstrate its scalability, we run a self-consistent calculation of a magnesium dislocation with about 80k electrons on a single GPU, which previously required about 7k GPUs. tensorlab.cms.caltech.edu/us… @DanishK42 @Caltech

Again, the woman is right. Women don't want flowers because they want flowers. They want flowers because it's an expression of how much you care about her. If she has to ask for them then they no longer serve their purpose. Also this is just a human trait.
