Who gets access to frontier AI is now a geopolitical question. But another question matters too: which economies are most exposed to it? Our new paper answers this by measuring national exposure to frontier AI across 141 countries. (1/8)

I visited Wurster Hall at UC Berkeley today. It was designed by, and currently houses, the architecture faculty. The UC Berkeley website notes that "Wurster is often voted Berkeley's ugliest building." I visited because I was curious about whether it would in person seem as unattractive as it does in photos. And, in short: it does. It's gaunt, austere, and filmed in grime. On an elysian campus, it stands out for its bleak hostility. It reminds me of the German submarine base in Bordeaux. The UC Berkeley page agrees that it was never designed to be attractive, quoting the curator of their design archives: “Wurster and his handpicked architects didn’t want anything romantic, or sentimental — they hated the idea of ‘making pretty buildings. They wanted a serious building.” I guess we have to concede success relative to their stated goals, but it does make one wonder what it all says about architecture as a discipline.

We are really excited to build independent evaluations of RSI progress and are actively hiring. We constantly see conflicting evidence about RSI progress. Most hinges on information coming from labs. To illustrate this, let's just look at evidence discussed *this week* that conflicts in whether it suggests RSI progress is fast or slow. xitter.cf/tobyordoxford/status/2… Results from OpenAI and Google evals indicate the time horizons for R&D tasks being automated are around ~15 minutes, which are much slower than METR time horizons for software tasks. This suggests we should have *slower* RSI timelines. xitter.cf/bneyshabur/status/2112… Results from Mirendil indicate that pretraining at a certain scale can be heavily automated such that it can be managed by a single pretraining researcher. This suggests we should have *faster* RSI timelines. xitter.cf/SemiAnalysis_/status/2… Results from Nvidia indicate that frontier models provide significant uplift for CUDA optimization. This suggests we should have *faster* RSI timelines. Each piece of evidence is more complex than what I write here. Interpreting them all together is confusing even if you trusted them all fully. And factoring in the underlying level of credibility is basically impossible: each result is basically just some plots and numbers selectively disclosed by labs in a tweet/talk/report. So deep sense-making about RSI progress is very hard. If you are interested in building independent RSI evals, apply here: cruxevals.com/careers/senior…
BREAKING NEWS🚨: NVIDIA ENGINEERS AT THE PYTORCH CONFERENCE JUST SAID THAT THE SPEED OF OPTIMIZING CUDA SOFTWARE WITH FRONTIER AI MODELS HAS INCREASED RAPIDLY October 2025 to August 2026: 5x in 1 year with expert human optimization September 2026 to October 2026: 2x in 1 month with AI assistance October 2026: 1.5x with AI orchestration + MegaKernels

AGI is imminent. Time has never been more valuable. Some of the smartest people you know are spending their days studying triangles for the GRE.

Firms are doing a lot to capture value from their own AI adoption, and yet often don't succeed. We are trying to understand the bottlenecks in practice better. If you have visibility into firm adoption whether as an employee, FDE, consultant, VC, or in some other capacity, we would love to hear from you. docs.google.com/forms/d/e/1F…

PSA: If you're a student and need @ExpectedParrot credits for your research, don't create a bunch of fake accounts w/ emails and make self-referrals to get credits. Just email us! We run a very loose, highly progressive fiscal policy & can make credits by fiat. We also have a soft-spot for students!

When we first worked on the tooling for the simulation that turned into this paper (sms.onlinelibrary.wiley.com/…) - agents had to pick a random choice before the game could proceed. agents invariably picked "42." 🤦‍♂️ We had to replace that part of the framework with a programatically generated random number generator.
This is the least surprising graph in the world if you understand how gradient descent works.

We can use public social media data---like reddit---to track and detect surprising ways people are experiencing AI on a personal level. A sort of "early warning system" for behaviors, opportunities, and challenges that might arise, capturing unanticipated issues that we wouldn't be able to capture using evals that have to be designed in advance based on foreknowledge of the issues. For example, data from r/ChatGPT shows that users are no longer exchanging prompt tricks as much as they used to, but are spending more time discussing their attachment to and companionship with AI. These are some of the interesting insights from @jessicadai_ 's research, which we're extremely privileged to share as our first ever @freesystemslab guest post! freesystems.substack.com/p/b…

I'm on the job market this year! I work on measuring the societal impacts (overreliance, homogenization etc.) of AI/LLMs and proposing ways to mitigate these. I'm at #COLM this week, and #NeurIPS later this year, and would love to chat more!

While I'm beyond thrilled that our tools are being used to push forward the research frontier, it also showed us limitations. But by this team publishing exactly what they're doing, we (@ExpectedParrot ) can build what's now needed e.g., I'm now thinking about how we can support this probe approach w/ our tools github.com/expectedparrot/ed… 1/
Replying to @abhishekn
We compare these two mech. interp based methods with simple prompt based fine tuning (implemented through @ExpectedParrot's wonderful library) -- which we also use to run a bunch of these experiments)

I have written extensively about the value of independent experts external to the frontier labs. I personally have chosen to remain independent at great financial opportunity cost. So it might surprise some that I am often quite supportive of my friends, colleagues, mentees, and mentors taking roles at frontier labs. I think these roles often are high-impact, rewarding, and exciting. With that said, today's events made me want to comment on the one consequence I personally find most saddening. Many of those deeply enmeshed in the frontier AI space might feel this in a way most farther away probably do not. It is the sadness of no longer seeing these folks contribute to public discourse on AI. First, as a point of clarification, I want to distinguish this from publishing open research. A well-understood cost in today's environment of joining a frontier lab is sacrificing the ability to openly publish research. There are some exceptions based on topic, company, and circumstance, but this is largely true. This cost is also something to be sad about, but what I am referring to is broader. To be glib, it is their contributions via Twitter, not arXiv, that I am talking about here. Dan Selsam's essay today reminded me of this. Dan and I were both Stanford PhDs advised by @percyliang. Our PhDs did not overlap, but I certainly knew of Dan when I was a student, and Percy occasionally referenced him to me as a north star in a certain sense. I have met Dan on a few occasions over the years. As many who know him better than I have already said, he is brilliant and prescient. My favorite example of this is his work on AI for math via the IMO grand challenge: quantamagazine.org/at-the-in… This challenge, initiated around the time of GPT-3, seemed absolutely ludicrous to me at the time. Because Dan was a former student of Percy, I said nothing at the time, but I mean it seemed entirely outlandish. As many have commented with the recent advances in AI for math, it seemed ridiculous to think AI would be able to get an IMO gold at a time when the most promising models of the day (GPT-3) could barely add at the level of a first grader. Everyone should read what he has to say. But what I want to comment is on the broader trend. As I experience it, when folks go to join the labs, they disappear from public discourse. Sure, we might see occasional glimmers like today's discourse about pacing AI, or past moments like the Anthropic supply chain risk designation or the OpenAI board coup or so on. And it is really important that lab employees speak in these moments. Society benefits greatly from their courage. And their courage should not be taken for granted. Yet I truly miss their participation in the day-to-day public discourse on what is happening with AI and how it will affect our society. There are so many incredible people at these labs, many of whom I would consider the world-best experts on certain topics, and I miss seeing what they have to say.

🚨🚨🚨 New paper alert 🚨🚨🚨 To understand LLMs impact on work, we first need to examine their capabilities across the entire occupation distribution. Doing this in a scalable way is hard and costly. Presenting - "ORQA: An Occupation-Realistic Question and Answer Framework for LLM Professional Knowledge" a new working paper with @serinachang5 and @ShreyasK1609 that takes this challenge head on! paper: arxiv.org/abs/2609.12366 dashboard: orqabench.org
