“How Well Does RL Scale?” by Toby_Ord 30.10.2025

This is the latest in a series of essays on AI Scaling. You can find the others on my site. Summary: RL-training for LLMs scales surprisingly poorly. Most of its gains are from allowing LLMs to productively use longer chains of thought, allowing them to think longer about a problem. There is some improvement for a fixed length of answer, but not enough to drive AI progress. Given the scaling up of...

“An Opinionated Guide to Privacy Despite Authoritarianism” by TurnTrout 30.10.2025

I've created a highly specific and actionable privacy guide, sorted by importance and venturing several layers deep into the privacy iceberg. I start with the basics (password manager) but also cover the obscure (dodging the millions of Bluetooth tracking beacons which extend from stores to traffic lights; anti-stingray settings; flashing GrapheneOS on a Pixel). I feel strongly motivated by c...

“Cancer has a surprising amount of detail” by Abhishaike Mahajan 30.10.2025

There is a very famous essay titled ‘Reality has a surprising amount of detail’. The thesis of the article is that reality is filled, just filled, with an incomprehensible amount of materially important information, far more than most people would naively expect. Some of this detail is inherent in the physical structure of the universe, and the rest of it has been generated by centuries of passion...

“AIs should also refuse to work on capabilities research” by Davidmanheim 29.10.2025

There's a strong argument that humans should stop trying to build more capable AI systems, or at least slow down progress. The risks are plausibly large but unclear, and we’d prefer not to die. But the roadmaps of the companies pursuing these systems envision increasingly agentic AI systems taking over the key tasks of researching and building superhuman AI systems, and humans will therefore...

“On Fleshling Safety: A Debate by Klurl and Trapaucius.” by Eliezer Yudkowsky 27.10.2025

(23K words; best considered as nonfiction with a fictional-dialogue frame, not a proper short story.) Prologue: Klurl and Trapaucius were members of the machine race. And no ordinary citizens they, but Constructors: licensed, bonded, and insured; proven, experienced, and reputed. Together Klurl and Trapaucius had collaborated on such famed artifices as the Eternal Clock, Silicon Sphere, Wandering...

“EU explained in 10 minutes” by Martin Sustrik 24.10.2025

If you want to understand a country, you should pick a similar country that you are already familiar with, research the differences between the two and there you go, you are now an expert. But this approach doesn’t quite work for the European Union. You might start, for instance, by comparing it to the United States, assuming that EU member countries are roughly equivalent to U.S. states. But that...

“Cheap Labour Everywhere” by Morpheus 24.10.2025

I recently visited my girlfriend's parents in India. Here is what that experience taught me: Yudkowsky has this facebook post where he makes some inferences about the economy after noticing two taxis stayed in the same place while he got his groceries. I had a few similar experiences while I was in India, though sadly I don't remember them in enough detail to illustrate them in as much d...

[Linkpost] “Consider donating to AI safety champion Scott Wiener” by Eric Neyman 24.10.2025

This is a link post. Written in my personal capacity. Thanks to many people for conversations and comments. Written in less than 24 hours; sorry for any sloppiness. It's an uncanny, weird coincidence that the two biggest legislative champions for AI safety in the entire country announced their bids for Congress just two days apart. But here we are. On Monday, I put out a long blog post making...

“Which side of the AI safety community are you in?” by Max Tegmark 23.10.2025

In recent years, I’ve found that people who self-identify as members of the AI safety community have increasingly split into two camps: Camp A) "Race to superintelligence safely”: People in this group typically argue that "superintelligence is inevitable because of X”, and it's therefore better that their in-group (their company or country) build it first. X is typically some combin...

“Doomers were right” by Algon 23.10.2025

There's an argument I sometimes hear against existential risks, or any other putative change that some are worried about, that goes something like this: 'We've seen time after time that some people will be afraid of any change. They'll say things like "TV will destroy people's ability to read", "coffee shops will destroy the social order","machines...

“Do One New Thing A Day To Solve Your Problems” by Algon 22.10.2025

People don't explore enough. They rely on cached thoughts and actions to get through their day. Unfortunately, this doesn't lead to them making progress on their problems. The solution is simple. Just do one new thing a day to solve one of your problems. Intellectually, I've always known that annoying, persistent problems often require just 5 seconds of actual thought. But seeing a...

“Humanity Learned Almost Nothing From COVID-19” by niplav 21.10.2025

Summary: Looking over humanity's response to the COVID-19 pandemic, almostsix years later, reveals that we've forgotten to fulfill our intent atpreparing for the next pandemic. I rant. content warning: A single carefully placed slur. If we want to create a world free of pandemics and other biologicalcatastrophes, the time to act is now. —US White House, “ FACT SHEET: The Biden Administra...

“Consider donating to Alex Bores, author of the RAISE Act” by Eric Neyman 20.10.2025

Written by Eric Neyman, in my personal capacity. The views expressed here are my own. Thanks to Zach Stein-Perlman, Jesse Richardson, and many others for comments. Over the last several years, I’ve written a bunch of posts about politics and political donations. In this post, I’ll tell you about one of the best donation opportunities that I’ve ever encountered: donating to Alex Bores, who announce...

“Meditation is dangerous” by Algon 20.10.2025

Here's a story I've heard a couple of times. A youngish person is looking for some solutions to their depression, chronic pain, ennui or some other cognitive flaw. They're open to new experiences and see a meditator gushing about how amazing meditation is for joy, removing suffering, clearing one's mind, improving focus etc. They invite the young person to a meditation retreat....

“That Mad Olympiad” by Tomás B. 19.10.2025

"I heard Chen started distilling the day after he was born. He's only four years old, if you can believe it. He's written 18 novels. His first words were, "I'm so here for it!" Adrian said. He's my little brother. Mom was busy in her world model. She says her character is like a "villainess" or something - I kinda worry it's a sex thing. It's...

“The ‘Length’ of ‘Horizons’” by Adam Scholl 17.10.2025

Current AI models are strange. They can speak—often coherently, sometimes even eloquently—which is wild. They can predict the structure of proteins, beat the best humans at many games, recall more facts in most domains than human experts; yet they also struggle to perform simple tasks, like using computer cursors, maintaining basic logical consistency, or explaining what they know without wholesal...

“Don’t Mock Yourself” by Algon 15.10.2025

About half a year ago, I decided to try stop insulting myself for two weeks. No more self-deprecating humour, calling myself a fool, or thinking I'm pathetic. Why? Because it felt vaguely corrosive. Let me tell you how it went. Spoiler: it went well. The first thing I noticed was how often I caught myself about to insult myself. It happened like multiple times an hour. I would lay in bed at n...

“If Anyone Builds It Everyone Dies, a semi-outsider review” by dvd 14.10.2025

About me and this review: I don’t identify as a member of the rationalist community, and I haven’t thought much about AI risk. I read AstralCodexTen and used to read Zvi Mowshowitz before he switched his blog to covering AI. Thus, I’ve long had a peripheral familiarity with LessWrong. I picked up IABIED in response to Scott Alexander's review, and ended up looking here to see what reactions w...

“The Most Common Bad Argument In These Parts” by J Bostock 12.10.2025

I've noticed an antipattern. It's definitely on the dark pareto-frontier of "bad argument" and "I see it all the time amongst smart people". I'm confident it's the worst, common argument I see amongst rationalists and EAs. I don't normally crosspost to the EA forum, but I'm doing it now. I call it Exhaustive Free Association. Exhaustive Free Associ...

“Towards a Typology of Strange LLM Chains-of-Thought” by 1a3orn 11.10.2025

Intro LLMs being trained with RLVR (Reinforcement Learning from Verifiable Rewards) start off with a 'chain-of-thought' (CoT) in whatever language the LLM was originally trained on. But after a long period of training, the CoT sometimes starts to look very weird; to resemble no human language; or even to grow completely unintelligible. Why might this happen? I've seen a lot of specu...

“I take antidepressants. You’re welcome” by Elizabeth 10.10.2025

It's amazing how much smarter everyone else gets when I take antidepressants. It makes sense that the drugs work on other people, because there's nothing in me to fix. I am a perfect and wise arbiter of not only my own behavior but everyone else's, which is a heavy burden because some of ya’ll are terrible at life. You date the wrong people. You take several seconds longer than nece...

“Inoculation prompting: Instructing models to misbehave at train-time can improve run-time behavior” by Sam Marks 10.10.2025

This is a link post for two papers that came out today: Inoculation Prompting: Eliciting traits from LLMs during training can suppress them at test-time (Tan et al.) Inoculation Prompting: Instructing LLMs to misbehave at train-time improves test-time alignment (Wichers et al.) These papers both study the following idea[1]: preventing a model from learning some undesired behavior during fine-tunin...

“Hospitalization: A Review” by Logan Riggs 10.10.2025

I woke up Friday morning w/ a very sore left shoulder. I tried stretching it, but my left chest hurt too. Isn't pain on one side a sign of a heart attack? Chest pain, arm/shoulder pain, and my breathing is pretty shallow now that I think about it, but I don't think I'm having a heart attack because that'd be terribly inconvenient. But it'd also be very dumb if I died cause...

“What, if not agency?” by abramdemski 09.10.2025

Sahil has been up to things. Unfortunately, I've seen people put effort into trying to understand and still bounce off. I recently talked to someone who tried to understand Sahil's project(s) several times and still failed. They asked me for my take, and they thought my explanation was far easier to understand (even if they still disagreed with it in the end). I find Sahil's thinkin...

“The Origami Men” by Tomás B. 08.10.2025

Of course, you must understand, I couldn't be bothered to act. I know weepers still pretend to try, but I wasn't a weeper, at least not then. It isn't even dangerous, the teeth only sharp to its target. But it would not have been right, you know? That's the way things are now. You ignore the screams. You put on a podcast: two guys talking, two guys who are slightly cleverer tha...
