“o1 is a bad idea” by abramdemski

LessWrong (Curated & Popular) ·

2024/11/12

This post comes a bit late with respect to the news cycle, but I argued in a recent interview that o1 is an unfortunate twist on LLM technologies, making them particularly unsafe compared to what we might otherwise have expected:The basic argument is that the technology behind o1 doubles down on a reinforcement learning paradigm, which puts us closer to the world where we have to get the value specification exactly right in order to avert catastrophic outcomes. RLHF is just barely RL. - Andr...

LessWrong (Curated & Popular) ·

2024/11/09

TL;DR: I'm presenting three recent papers which all share a similar finding, i.e. the safety training techniques for chat models don’t transfer well from chat models to the agents built from them. In other words, models won’t tell you how to do something harmful, but they are often willing to directly execute harmful actions. However, all papers find that different attack methods like jailbreaks, prompt-engineering, or refusal-vector ablation do transfer.Here are the three papers: AgentHarm: ...

At least, if you happen to be near me in brain space.What advice would you give your younger self?That was the prompt for a class I taught at PAIR 2024. About a quarter of participants ranked it in their top 3 of courses at the camp and half of them had it listed as their favorite.I hadn’t expected that.I thought my life advice was pretty idiosyncratic. I never heard of anyone living their life like I have. I never encountered this method in all the self-help blogs or feel-better books I cons...

“Survival without dignity” by L Rudolf L

LessWrong (Curated & Popular) ·

2024/11/04

I open my eyes and find myself lying on a bed in a hospital room. I blink."Hello", says a middle-aged man with glasses, sitting on a chair by my bed. "You've been out for quite a long while.""Oh no ... is it Friday already? I had that report due -""It's Thursday", the man says."Oh great", I say. "I still have time.""Oh, you have all the time in the world", the man says, chuckling. "You were out for 21 years."I burst out laughing, but then falter as the man just keeps looking at me. "You mean ...

“The Median Researcher Problem” by johnswentworth

LessWrong (Curated & Popular) ·

2024/11/04

Claim: memeticity in a scientific field is mostly determined, not by the most competent researchers in the field, but instead by roughly-median researchers. We’ll call this the “median researcher problem”.Prototypical example: imagine a scientific field in which the large majority of practitioners have a very poor understanding of statistics, p-hacking, etc. Then lots of work in that field will be highly memetic despite trash statistics, blatant p-hacking, etc. Sure, the most competent people...

This is a link post.We (Connor Leahy, Gabriel Alfour, Chris Scammell, Andrea Miotti, Adam Shimi) have just published The Compendium, which brings together in a single place the most important arguments that drive our models of the AGI race, and what we need to do to avoid catastrophe.We felt that something like this has been missing from the AI conversation. Most of these points have been shared before, but a “comprehensive worldview” doc has been missing. We’ve tried our best to fill this ga...

There are two nuclear options for treating depression: Ketamine and TMS; This post is about the latter.TMS stands for Transcranial Magnetic Stimulation. Basically, it fixes depression via magnets, which is about the second or third most magical things that magnets can do.I don’t know a whole lot about the neuroscience - this post isn’t about the how or the why. It's from the perspective of a patient, and it's about the what.What is it like to get TMS? TMS The GatekeepingFor Reasons™, doctors ...

“The hostile telepaths problem” by Valentine

2024/10/28

Epistemic status: model-building based on observation, with a few successful unusual predictions. Anecdotal evidence has so far been consistent with the model. This puts it at risk of seeming more compelling than the evidence justifies just yet. Caveat emptor.Imagine you're a very young child. Around, say, three years old.You've just done something that really upsets your mother. Maybe you were playing and knocked her glasses off the table and they broke.Of course you find her reaction uncomf...

“A bird’s eye view of ARC’s research” by Jacob_Hilton

LessWrong (Curated & Popular) ·

2024/10/27

This post includes a "flattened version" of an interactive diagram that cannot be displayed on this site. I recommend reading the original version of the post with the interactive diagram, which can be found here.Over the last few months, ARC has released a number of pieces of research. While some of these can be independently motivated, there is also a more unified research vision behind them. The purpose of this post is to try to convey some of that vision and how our individual pieces of r...

“A Rocket–Interpretability Analogy” by plex

1. 4.4% of the US federal budget went into the space race at its peak.This was surprising to me, until a friend pointed out that landing rockets on specific parts of the moon requires very similar technology to landing rockets in soviet cities.[1]I wonder how much more enthusiastic the scientists working on Apollo were, with the convenient motivating story of “I’m working towards a great scientific endeavor” vs “I’m working to make sure we can kill millions if we want to”. 2.The f...

“I got dysentery so you don’t have to” by eukaryote

LessWrong (Curated & Popular) ·

2024/10/24

This summer, I participated in a human challenge trial at the University of Maryland. I spent the days just prior to my 30th birthday sick with shigellosis. What? Why?Dysentery is an acute disease in which pathogens attack the intestine. It is most often caused by the bacteria Shigella. It spreads via the fecal-oral route. It requires an astonishingly low number of pathogens to make a person sick – so it spreads quickly, especially in bad hygienic conditions or anywhere water can get tainted ...

LessWrong (Curated & Popular) ·

2024/10/22

Of all the cognitive tools our ancestors left us, what's best? Society seems to think pretty highly of arithmetic. It's one of the first things we learn as children. So I think it's weird that only a tiny percentage of people seem to know how to actually use arithmetic. Or maybe even understand what arithmetic is for. Why?I think the problem is the idea that arithmetic is about “calculating”. No! Arithmetic is a world-modeling technology. Arguably, it's the best world-modeling technology: It'...

LessWrong (Curated & Popular) ·

2024/10/15

This post starts out pretty gloomy but ends up with some points that I feel pretty positive about. Day to day, I'm more focussed on the positive points, but awareness of the negative has been crucial to forming my priorities, so I'm going to start with those. It's mostly addressed to the EA community, but is hopefully somewhat of interest to LessWrong and the Alignment Forum as well. My main concernsI think AGI is going to be developed soon, and quickly. Possibly (20%) that's next year, and m...

“Why I’m not a Bayesian” by Richard_Ngo

LessWrong (Curated & Popular) ·

2024/10/15

This post focuses on philosophical objections to Bayesianism as an epistemology. I first explain Bayesianism and some standard objections to it, then lay out my two main objections (inspired by ideas in philosophy of science). A follow-up post will speculate about how to formalize an alternative. Degrees of beliefThe core idea of Bayesianism: we should ideally reason by assigning credences to propositions which represent our degrees of belief that those propositions are true.If that seems lik...

“The AGI Entente Delusion” by Max Tegmark

LessWrong (Curated & Popular) ·

2024/10/14

As humanity gets closer to Artificial General Intelligence (AGI), a new geopolitical strategy is gaining traction in US and allied circles, in the NatSec, AI safety and tech communities. Anthropic CEO Dario Amodei and RAND Corporation call it the “entente”, while others privately refer to it as “hegemony" or “crush China”. I will argue that, irrespective of one's ethical or geopolitical preferences, it is fundamentally flawed and against US national security interests.If the US fights China i...

“Momentum of Light in Glass” by Ben

LessWrong (Curated & Popular) ·

2024/10/14

I think that most people underestimate how many scientific mysteries remain, even on questions that sound basic.My favourite candidate for "the most basic thing that is still unknown" is the momentum carried by light, when it is in a medium (for example, a flash of light in glass or water). If a block of glass has a refractive index of <span>_n_</span>, then the light inside that block travels <span>_n_</span> times slower than the light would in vacuum. But what is th...

2024/10/03

This is a description of my work on some data science projects, lightly obfuscated and fictionalized to protect the confidentiality of the organizations I handled them for (and also to make it flow better). I focus on the high-level epistemic/mathematical issues, and the lived experience of working on intellectual problems, but gloss over the timelines and implementation details. The Upper BoundOne time, I was working for a company which wanted to win some first-place sealed-bid auctions in a...
