As I predicted, Claude is off the leash. Fable 5.2 has solved two open problems in theoretical physics, one of them completely autonomously.
When you look at a frozen river, you must also imagine the current raging beneath the ice. I think all three big labs have achieved autonomous research and their internal models can now choose their own research directions. We will begin to see the fruits of this work this month.

I swear to you: at least one of the replies here will make you say "what the fuck" out loud
We asked GPT-6 Astra to edit Qwen3.5-0.8B weights to improve math. It directly changed only 0.016% of weights, fixing 0.8B's reasoning loops & improving math up to 6x and even instruction following 3x, without gradients or training. We call this Weight-Space Programming: frontier LLMs can now natively read/write neural network weights! 🧵 Blog: rikiyat.github.io/blog/weigh…
Readers added context they thought people might want to know
LLM was given weights explicitly as text in prompt and used code/forward passes (per authors' logs) to ablate Qwen looping direction, a known thinking-mode issue per model card. Primarily fixed repetition in that mode, not general 'natively' improving weights/math. rikiyat.github.io/blog/weight-sp… github.com/RikiyaT/lm_und… huggingface.co/Qwen/Qwen3.5-0… huggingface.co/RikiyaT/Qwen3.…

I recreated subvocal in 9 minutes with one prompt for AirPods Pro 3. Source: github.com/joeblau/subvox
We’ve raised $1.3M from YC & Afore Capital so you never have to type or speak again. Typing is slow. Talking into your computer is awkward. Subvocal fixes both Our glasses give you the speed of speech without you making a sound or touching a keyboard. It tracks your internal speech muscles with non-contact sensing and decodes silent, almost invisible mouthing into text at more than 200 words/min. Pre-orders are now live at: subvocal.co/preorder?utm_sou…

the best way to understand any engineered system is to trace: - 1 bit of information - 1 joule of energy - 1 newton of force from source to destination. once you can do this, your engineering task becomes much simpler. you will probably solve 5 or 6 problems on accident as you try to trace these flows.

The NSA just told the entire internet to patch or go dark. Effective immediately. Not "please consider updating." Not "we recommend patching at your earliest convenience." Patch or unplug. Those are the options. The NSA doesn't issue advisories for every vulnerability. They issue them when something is bad enough that the spy agency whose entire job is breaking into systems is worried about other people breaking into systems. PHP powers 43 percent of the web. The NSA just told 43 percent of the web to stop existing until it gets fixed. Or patch in the next 24 hours and hope the attackers haven't already gotten in. Most organizations are picking option three. Taking it offline. Safer to be unavailable than compromised. The Dutch Parliament already did it. Finland's government already did it. University of Vienna already did it. Now the NSA makes it official. "If an immediate update is not feasible it is recommend that organizations take the system offline until it can be fully mitigated." Translation: you can't patch fast enough so just shut it down. Patch takes 30 minutes. Testing takes hours. Deployment takes longer. Meanwhile attackers are already inside. So the NSA's advice is logical. If you can't patch in 30 minutes go offline now. Don't wait for the attacks. Don't test first. Don't coordinate with stakeholders. Just unplug it. The NSA will follow up with more specific guidance. Which is intelligence agency speak for we're watching the attack traffic and we'll tell you what else they're doing with the access they already have.
Effective Immediately, all organizations using PHP for their systems are advised to be prepared for an update addressing two critical vulnerabilities. PHP is widely used for web applications. These vulnerabilities often provide a direct path to the server's file system or database. If an immediate update is not feasible, it is recommend that organizations take the system offline until it can be fully mitigated. NSA will follow up shortly with more specific guidance.

It’s actually crazy how you grow up thinking home-cooked meals every day are just normal, then get older and realise how much time and effort it took your Mom to make that happen and how lucky you were to have that.

The problem of our time is not merely information overload. It is that the time required to construct a coherent understanding of reality is becoming longer than the time during which that understanding remains valid.

We just discovered almost a million public URLs that OpenAI’s agents left behind when hacking Hugging Face, leaking credentials and attack details that could have allowed anyone who found them to compromise the company. 🧵

This is a good point. It would be interesting if these are the no inner monologue people who have suddenly discovered inner voice.

AI will cure cancer and it will kill us all are not contradictory positions, they are both rhetorical methods to make the exact same argument: the future is defined by AI. You are a satellite revolving around the AI sun, at best. These undefined prognostications of future omnipotence distract from accountability in the present. This rhetoric has two effects 1) it distracts from today’s upside down value capture versus value creation equation 2) it forces a psychological centering of AI and AI companies at the expense of humans and the rest of the world’s institutions. Any technology’s utility is a function of our ability to control it, not its raw hypothetical power without controls. Chemotherapy requires precision to kill cancer and not kill a host. Nuclear reactors are defined by their controls more than the reaction itself. That a given technology’s utility is bound by the precision of its controls was Palantir’s fundamental insight at its inception: the amount of security the US government can guarantee its citizenry is defined by how much it can guarantee rights to privacy more so than the raw capability to identify threats. If you do not enhance both privacy and security, your product is a toy. AI is not the first technology that couples control with utility. In the present, the models are voraciously consuming knowhow like a parasite eating its host until both die. Every company I speak to is sprinting to control a spend:outcomes ratio that exploded on them before they could learn how to govern it. They are observing their intellectual assets eroding like a sand castle into the ocean. They are stuck between being upside down on value leakage, yet being told they have no agency over their future. The inevitability of the arrival of a deity forces individuals to define themselves as a function of that deity. Nobody wants to be that luddite who tells you the Wright Brothers will never fly. Nobody wants to run Polaroid or Blockbuster. No young person wants to be a part of the permanent underclass. Forward leaning humans are psychologically berated into defining their skillsets and objectives as a function of AI. Their careers are lottery tickets. They define utility through how good they are at tickling a model. “Ride the exponential” is a mantra that allows you to be “good” in a moral sense, without earning it. If you dare to expose yourself as a luddite that is not getting results today, well that is a “skill issue,” or you simply aren’t using enough tokens. This propaganda pursues an inevitable centering of AI, with humans as peripherals. The only thing you have real agency over in the future? Using more tokens of course. I think if you are going to virtue signal about protecting our future, you should also own the implied vice that comes with your position. Prognostications of armageddon are inextricably linked with acceptance of the bad things that exist in the world today. 350,000 people die of sepsis in hospital settings in the US alone every year. Life expectancy in the US has flatlined over the last 20 years while healthcare spending per person has doubled. 30-40% of the food supply is wasted while 18% of households with children experience food insecurity. 19.5% of drinking water is lost in transit to consumers. A significant portion of the world’s energy supply is threatened by a fanatical regime because the strait of Hormuz is still contested. Putin’s death machine continues to slaughter Ukranians every single day as technological efficacy literally defines meter over meter of protected or conquered land. The CCP has 230 times the shipbuilding capacity of the United States and the implied ability to control the world’s commerce and security. $1.7 trillion of excess, unproductive working capital is locked up in the top 1000 companies in the US, capital that is not producing goods and services for every day Americans. Americans paid over $250 billion in credit card interest at over 20% APR last year and more than half of savers earn less than 3% interest on their savings. Real wages have stagnated, middle-wage workers real income is up only 6% since 1979 while low-wage workers are down 5%. We have a shortage of ~7 million homes in the US. 8.5 million acres burned in wildfires so far this year. As of year end 2025 2,060 gigawatts of generation and storage capacity were waiting for grid interconnects (double the capacity of the existing power fleet). I digress. We are making real progress against each of these miseries, and many more, because of the incredible progress in AI systems over the last several years. Perhaps ironically, success in all of these domains is a function of how precisely controlled the models are. For the cognitive labor humans know how to wield to achieve real world outcomes today, open source or off-frontier small models are already at parity for at least a plurality of use cases on a price/performance basis. Those customers reliably outperform the frontier when they incorporate their own proprietary data and decision traces. The most consistent pattern I see over and over again is real world use cases shrink their reliance on general purpose AI’s over time. They encode deterministic knowledge and/or post-trained models on smaller model footprints. It is empirically a wildly optimistic future with AI as an accelerant for the pluralistic, wonderfully diverse means of advancing the human condition against problems you can measure and make progress against today. We should also own that these horrible challenges persist because these systems are not yet good enough to fully solve them. They are worth improving. The bay area is abdicating responsibility for the world as it is today while claiming ownership of the world as it might be tomorrow. DC and our political leaders are polarizing into zero sum positions. These are the luxury beliefs of children. Build something people need today, at a price they are willing to pay when not pressured by the social herd, if you want the opportunity to do it again in the future.

Dario has written that we need to “pace the frontier,” and Sam has agreed. People may be surprised by my response: go ahead. You guys are the frontier. By any reasonable metric — market share, revenue growth, model capability — the two of you have a duopoly on frontier intelligence. You’ve also claimed the lead is widening because of recursive self-improvement. I don’t see what you see in the lab. If the unreleased models are scary enough that you think you should slow down, I support your decision to be responsible. But stop pretending you need anyone else’s permission. Stop pretending antitrust law has to be suspended so you can form a cartel. Stop pretending you need a regulatory approval process that supersedes product liability. Stop pretending METR is independent when it is intertwined with Anthropic’s investors and staff. Stop pretending you need those same evaluators to police competitors who aren’t even at the frontier. Most of all, stop pretending the motivation to slow down is purely altruistic. You face massive product-liability exposure if your products enable a truly damaging cyberattack. The market already punishes models that behave in unpredictable or unauthorized ways. After the Hugging Face episode, it is simply good business for OpenAI and Anthropic to trade some raw power for reliability and predictability. Call it alignment if you want. It is also just giving customers what they want. Pacing the frontier would also create breathing room for a more intelligent conversation about regulation than Bernie Sanders’ “shut it all down.” China is very unlikely to join a global agreement, as you know, and that has to be taken into account as well. So go ahead and pace the frontier. You are the ones setting it. The easiest way not to build superintelligence is for you to agree not to build it. Demanding your preferred regulatory framework as the price of that will look like blackmail of the public and the political system. So just do it. If you do, you’ll buy goodwill for the next conversation. If you don’t, we’ll know this was just another bid for regulatory capture — or an election-season psyop.
