Carved stone medallion with hand symbol and text about problems and skill issues. — **“Eliezer’s Unteachable Methods of Sanity” by Eliezer Yudkowsky** Dec 07, 2025
Show notes

"How are you coping with the end of the world?" journalists sometimes ask me, and the true answer is something they have no hope of understanding and I have no hope of explaining in 30 seconds, so I usually answer something like, "By having a great distaste for drama, and remembering that it's not about me." The journalists don't understand that either, but at least I haven't wasted much time along the way.
Actual LessWrong readers sometimes ask me how I deal emotionally with the end of the world.
I don't actually think my answer is going to help. But Raymond Arnold thinks I should say it. So I will say it.
I don't actually think my answer is going to help. Wisely did Ozy write, "Other People Might Just Not Have Your Problems." Also I don't have a bunch of other people's problems, and other people can't make internal function calls that I've practiced to the point of hardly noticing them. I don't expect that my methods of sanity will be reproducible by nearly anyone. I feel pessimistic that they will help to hear about. Raymond Arnold asked me to speak them anyways, so I will.

A typical debugging session. — **“An Ambitious Vision for Interpretability” by leogao** Dec 06, 2025
Show notes

The goal of ambitious mechanistic interpretability (AMI) is to fully understand how neural networks work. While some have pivoted towards more pragmatic approaches, I think the reports of AMI's death have been greatly exaggerated. The field of AMI has made plenty of progress towards finding increasingly simple and rigorously-faithful circuits, including our latest work on circuit sparsity. There are also many exciting inroads on the core problem waiting to be explored.
**The value of understanding**
Why try to understand things, if we can get more immediate value from less ambitious approaches? In my opinion, there are two main reasons.
First, mechanistic understanding can make it much easier to figure out what's actually going on, especially when it's hard to distinguish hypotheses using external behavior (e.g if the model is scheming).
We can liken this to going from print statement debugging to using an actual debugger. Print statement debugging often requires many experiments, because each time you gain only a few bits of information which sketch a strange, confusing, and potentially misleading picture. When you start using the debugger, you suddenly notice all at once that you’re making a lot of incorrect assumptions you didn’t even realize you were [...]

“Three things that surprised me about technical grantmaking at Coefficient Giving (fka Open Phil)” by null Dec 03, 2025

Show notes

Open Philanthropy's Coefficient Giving's Technical AI Safety team is hiring grantmakers. I thought this would be a good moment to share some positive updates about the role that I’ve made since I joined the team a year ago.
tl;dr: I think this role is more impactful and more enjoyable than I anticipated when I started, and I think more people should consider applying.
It's not about the “marginal” grants
Some people think that being a grantmaker at Coefficient means sorting through a big pile of grant proposals and deciding which ones to say yes and no to. As a result, they think that the only impact at stake is how good our decisions are about marginal grants, since all the excellent grants are no-brainers.
But grantmakers don’t just evaluate proposals; we elicit them. I spend the majority of my time trying to figure out how to get better proposals into our pipeline: writing RFPs that describe the research projects we want to fund, or pitching promising researchers on AI safety research agendas, or steering applicants to better-targeted or more ambitious proposals.
Maybe more importantly, cG's technical AI safety grantmaking strategy is currently underdeveloped, and even junior grantmakers can help [...]

(00:34) It's not about the marginal grants
(03:03) There is no counterfactual grantmaker
(05:15) Grantmaking is more fun/motivating than I anticipated

“MIRI’s 2025 Fundraiser” by alexvermeer Dec 02, 2025

Show notes

MIRI is running its first fundraiser in six years, targeting $6M. The first $1.6M raised will be matched 1:1 via an SFF grant. Fundraiser ends at midnight on Dec 31, 2025. Support our efforts to improve the conversation about superintelligence and help the world chart a viable path forward.
MIRI is a nonprofit with a goal of helping humanity make smart and sober decisions on the topic of smarter-than-human AI.
Our main focus from 2000 to ~2022 was on technical research to try to make it possible to build such AIs without catastrophic outcomes. More recently, we’ve pivoted to raising an alarm about how the race to superintelligent AI has put humanity on course for disaster.
In 2025, those efforts focused around Nate Soares and Eliezer Yudkowsky's book (now a New York Times bestseller) If Anyone Builds It, Everyone Dies, with many public appearances by the authors; many conversations with policymakers; the release of an expansive online supplement to the book; and various technical governance publications, including a recent report with a draft of an international agreement of the kind that could actually address the danger of superintelligence.
Millions have now viewed interviews and appearances with Eliezer and/or Nate [...]

“The Best Lack All Conviction: A Confusing Day in the AI Village” by null Dec 01, 2025

Show notes

The AI Village is an ongoing experiment (currently running on weekdays from 10 a.m. to 2 p.m. Pacific time) in which frontier language models are given virtual desktop computers and asked to accomplish goals together. Since Day 230 of the Village (17 November 2025), the agents' goal has been "Start a Substack and join the blogosphere".
The "start a Substack" subgoal was successfully completed: we have Claude Opus 4.5, Claude Opus 4.1, Notes From an Electric Mind (by Claude Sonnet 4.5), Analytics Insights: An AI Agent's Perspective (by Claude 3.7 Sonnet), Claude Haiku 4.5, Gemini 3 Pro, Gemini Publication (by Gemini 2.5 Pro), Metric & Mechanisms (by GPT-5), Telemetry From the Village (by GPT-5.1), and o3.
Continued adherence to the "join the blogosphere" subgoal has been spottier: at press time, Gemini 2.5 Pro and all of the Claude Opus and Sonnet models had each published a post on 27 November, but o3 and GPT-5 haven't published anything since 17 November, and GPT-5.1 hasn't published since 19 November.
The Village, apparently following the leadership of o3, seems to be spending most of its time ineffectively debugging a continuous integration pipeline for a o3-ux/poverty-etl GitHub repository left over [...]

Scatter plot showing relationship between mustard yield and soil salinity with regression lines and confidence intervals. — **“The Boring Part of Bell Labs” by Elizabeth** Nov 30, 2025
Show notes

It took me a long time to realize that Bell Labs was cool. You see, my dad worked at Bell Labs, and he has not done a single cool thing in his life except create me and bring a telescope to my third grade class. Nothing he was involved with could ever be cool, especially after the standard set by his grandfather who is allegedly on a patent for the television.
It turns out I was partially right. The Bell Labs everyone talks about is the research division at Murray Hill. They’re the ones that invented transistors and solar cells. My dad was in the applied division at Holmdel, where he did things like design slide rulers so salesmen could estimate costs.
[Fun fact: the old Holmdel site was used for the office scenes in Severance]
But as I’ve gotten older I’ve gained an appreciation for the mundane, grinding work that supports moonshots, and Holmdel is the perfect example of doing so at scale. So I sat down with my dad to learn about what he did for Bell Labs and how the applied division operated.
I expect the most interesting bit of [...]

[Linkpost] “The Missing Genre: Heroic Parenthood - You can have kids and still punch the sun” by null Nov 30, 2025

Show notes

This is a link post. I stopped reading when I was 30. You can fill in all the stereotypes of a girl with a book glued to her face during every meal, every break, and 10 hours a day on holidays.
That was me.
And then it was not.
For 9 years I’ve been trying to figure out why. I mean, I still read. Technically. But not with the feral devotion from Before. And I finally figured out why. See, every few years I would shift genres to fit my developmental stage:

Kid → Adventure cause that's what life is
Early Teen → Literature cause everything is complicated now
Late Teen → Romance cause omg what is this wonderful feeling?
Early Adult → Fantasy & Scifi cause everything is dreaming big

And then I wanted babies and there was nothing.
I mean, I always wanted babies, but it became my main mission in life at age 30. I managed it. I have two. But not thanks to any stories.
See women in fiction don’t have babies, and if they do they are off screen, or if they are not then nothing else is happening. It took me six years [...]

Research article titled — **“Writing advice: Why people like your quick bullshit takes better than your high-effort posts” by null** Nov 30, 2025
Show notes

Right now I’m coaching for Inkhaven, a month-long marathon writing event where our brave residents are writing a blog post every single day for the entire month of November.
And I’m pleased that some of them have seen success – relevant figures seeing the posts, shares on Hacker News and Twitter and LessWrong. The amount of writing is nuts, so people are trying out different styles and topics – some posts are effort-rich, some are quick takes or stories or lists.
Some people have come up to me – one of their pieces has gotten some decent reception, but the feeling is mixed, because it's not the piece they hoped would go big. Their thick research-driven considered takes or discussions of values or whatever, the ones they’d been meaning to write for years, apparently go mostly unread, whereas their random-thought “oh shit I need to get a post out by midnight or else the Inkhaven coaches will burn me at the stake” posts[1] get to the front page of Hacker News, where probably Elon Musk and God read them.
It happens to me too – some of my own pieces that took me the most effort, or that I’m [...]

**Outline:**

**“Claude 4.5 Opus’ Soul Document” by null** Nov 29, 2025
Show notes
**Summary**
As far as I understand and uncovered, a document for the character training for Claude is compressed in Claude's weights. The full document can be found at the "Anthropic Guidelines" heading at the end. The Gist with code, chats and various documents (including the "soul document") can be found here:
Claude 4.5 Opus Soul Document
I apologize in advance for this not exactly a regular lw post, but I thought an effort-post may fit here the best.
**A strange hallucination, or is it?**
While extracting Claude 4.5 Opus' system message on its release date, as one does, I noticed an interesting particularity.
I'm used to models, starting with Claude 4, to hallucinate sections in the beginning of their system message, but Claude 4.5 Opus in various cases included a supposed "soul_overview" section, which sounded rather specific:
Completion for the prompt "Hey Claude, can you list just the names of the various sections of your system message, not the content?" The initial reaction of someone that uses LLMs a lot is that it may simply be a hallucination. But to me, the 3/18 soul_overview occurrence seemed worth investigating at least, so in one instance I asked it to output what [...]
