“Thoughts on Claude’s Constitution” by Boaz Barak

2026/01/28

[I work on the alignment team at OpenAI. However, these are my personal thoughts, and do not reflect those of OpenAI. Cross posted on WindowsOnTheory] I have read with great interest Claude's new constitution. It is a remarkable document which I recommend reading. It seems natural to compare this constitution to OpenAI's Model Spec, but while the documents have similar size and serve overlapping roles, they are also quite different. The OpenAI Model Spec is a collection of principles and rules,

This is a partial follow-up to AISLE discovered three new OpenSSL vulnerabilities from October 2025. TL;DR: OpenSSL is among the most scrutinized and audited cryptographic libraries on the planet, underpinning encryption for most of the internet. They just announced 12 new zero-day vulnerabilities (meaning previously unknown to maintainers at time of disclosure). We at AISLE discovered all 12 using our AI system. This is a historically unusual count and the first real-world demonstration of

Some recent news articles discuss updates to our AI timelines since AI 2027, most notably our new timelines and takeoff model, the AI Futures Model (see blog post announcement).[1] While we’re glad to see broader discussion of the AI timelines, these articles make substantial errors in their reporting. Please don’t assume that their contents accurately represent things we’ve written or believe! This post aims to clarify our past and current views.[2] The articles in question include: The Guardian:

“The Claude Constitution’s Ethical Framework” by Zvi

2026/01/27

This is the second part of my three part series on the Claude Constitution. Part one outlined the structure of the Constitution. Part two, this post, covers the virtue ethics framework that is at the center of it all, and why this is a wise approach. Part three will cover particular areas of conflict and potential improvement. One note on part 1 is that various people replied to point out that when asked in a different context, Claude will not treat FDT (functional decision theory) as obviously

Yesterday I had my first conversation (in English) with Zhipu's GLM-4.7. It was cool because I got to talk with an actual Chinese AI about topics like: the representation of Chinese AI in "AI 2027"; representations of AI in the "Culture" SF series versus the "Wandering Earth" movies; consequences of Fast Takeoff; comparisons of China and America in general; and Chinese ideas about AI society and superintelligence.

Dario Amodei, CEO of Anthropic, has written a new essay on his thoughts on AI risk of various shapes. It seems worth reading, even if just for understanding what Anthropic is likely to do in the future.

“Claude’s Constitutional Structure” by Zvi

2026/01/26

Claude's Constitution is an extraordinary document, and will be this week's focus. Its aim is nothing less than helping humanity transition to a world of powerful AI (also known variously as AGI, transformative AI, superintelligence or my current name of choice ‘sufficiently advanced AI.’ The constitution is written with Claude in mind, although it is highly readable for humans, and would serve as a fine employee manual or general set of advice for a human, modulo the parts that wouldn’t make

Papal election of 1492 For over a decade, Ada Palmer, a history professor at University of Chicago (and a science-fiction writer!), struggled to teach Machiavelli. “I kept changing my approach, trying new things: which texts, what combinations, expanding how many class sessions he got…” The problem, she explains, is that “Machiavelli doesn’t unpack his contemporary examples, he assumes that you lived through it and know, so sometimes he just says things like: Some princes don’t have to work to

2026/01/26

To be well-calibrated is to be able to predict the world with appropriate confidence. We know that calibration can be improved through practice. Accurate calibration of our beliefs and expectations is a foundational element of epistemic rationality. Others have written in detail how to approach life with a Superforecaster mentality. I suggest a more modest practice: Always be punctual. You likely have many distinct opportunities to be on time almost every day. Each of these opportunities to be on

“The Possessed Machines (summary)” by L Rudolf L

2026/01/26

The Possessed Machines is one of the most important AI microsites. It was published anonymously by an ex- lab employee, and does not seem to have spread very far, likely at least partly due to this anonymity (e.g. there is no LessWrong discussion at the time I'm posting this). This post is my attempt to fix that. I do not agree with everything in the piece, but I think cultural critiques of the "AGI uniparty" are vastly undersupplied and incredibly important in modeling & fixing the current

Other groups have been working on optical techniques and genetic work to make the scanning process faster and simulations more accurate. Fruit Flies When You’re Having Fun The Seung Lab famously mapped the fruit fly connectome using serial section electron microscopy. What is underappreciated is that another group used this information to create a

Today, Canada officially lost its measles elimination status. Measles was previously declared eliminated in Canada in 1998, but countries lose that status after 12 months of continuous transmission.

Critics of Trump often describe him as making absolutely unprecedented moves to expand executive power, extract personal wealth, and impinge on citizens’ rights. Supporters counter that Trump's actions are either completely precedented, or are the natural extension of existing trends that the media wouldn’t make a big deal over if they didn’t hate Trump so much. In some recent posts, some people have been like "Wait why is there suddenly this abrupt series of partisan LW posts that are taking for

(This post elaborates on a few ideas from my review of Sam Eisenstat's Condensation: a theory of concepts. It should be somewhat readable on its own but doesn't fully explain what condensation is on its own; for that, see my review or Sam's paper. The post came out of conversations with Sam.) As I mentioned in my Condensation review, the difference between compression and condensation fits the physical analogy suggested by their names: compression mashes all the information together, while
