Here’s what I’ve been working on recently: @anthropicai. I’ll be spending a lot of my time on measurement and assessment of our AI systems, as well as thinking of ways govs/others can assess AI tech. There’s a lot to do!
One of my fav genres of AI paper is the hyper-specific paper for a particular applied use. Often, these papers are a nice way of understanding the difficulties of real world deployment. Sometimes, you also get SECRET POETRY like the title "CucumberVision at the Edge". Fantastic!

That time I tried to talk @jackclarkSF into being a poor for the rest of his life. Was on his way from Bloomberg to OpenAI and then Anthropic
Hiked Mt Diablo this weekend. It's an uncompromising place, full of secrets, vast and unfairly obscure. I saw coyotes and little bunnies and picked my way across a ridge, scrabbling on rocks that were so sharp and jagged they almost drew blood. #VOTENATURE2026
Best summary of juggling a toddler with a baby is finding a suspicious puddle of liquid in a bathroom and attending to it, then texting my wife "just cleaned it up. Good news - it was water, not piss!"

New on our Frontier Red Team blog: using Claude to formally verify software at large scale.
Formal verification can prove that code is free of certain bugs, but historically it has only been feasible for small codebases (or required a lot of expert time).
With AI models, however, this is beginning to change. In collaboration with @theoremlabs, we used Claude to prove security properties in over one hundred real-world open-source libraries over the span of a few weeks.

Between this and our prior commitments, roughly 20% of all Anthropic equity will be dedicated to the public good, and that commitment can grow as Anthropic grows.
We plan to use these funds to ensure more people can share in the benefits of AI, and to increase our ability to provide funding to deal with its risks.
We’re committing a portion of Anthropic’s shares to the Anthropic Public Benefit Fund, a new wholly owned entity dedicated entirely to the public benefit.
It will start off with 5% of our shares. For every 50% increase in the company’s value over a set baseline, we can contribute up to an extra 2%, subject to our board’s discretion.
In total, this means that roughly 20% of Anthropic’s shares are committed to the public good. Our co-founders have already pledged to donate 80% of their equity, and around half our employees are donating a portion of their equity as part of a donation matching program we’ve run since our founding.
In the post below, we share more details about our new fund.

I’m speaking at the IMF in an hour about the singularity and why I believe it has begun and the choices we'll need to make. Watch live here: youtube.com/live/Rqt9kWoTJbc…

I’m still half in disbelief
We asked Gemini Argon to teach the Apollo humanoid to play cornhole, and it zero-shotted it
All we gave it was a video of a person doing it. It then took control of the robot, generated its own sim env, performed some sysID, and trained launches on the real robot.
It took it a few real shots to improve and then land many consecutive airmails.
The process was so long and articulated that we asked the robot itself to explain what it did to us, as you can see at the end of the video. It even came up with the gestures
Great demo for a great model @googledeepmind @apptronik
I will be giving the Per Jacobsson Foundation Lecture at the IMF conference in Thailand on Saturday, during which I'm going to make the case that we are entering a period of massive, sudden change catalyzed by the advancing capabilities of AI systems.
Special Import AI announcement: In Monday's issue, there will be a video from a recent event I did with Robin Sloan where we talked about AI, fiction, and the future. Robin said we can read the Hugging Face hack as being like a play - a fascinating perspective!
Niche tweet, but the new Jamie T album is v good. "The Won" is especially nice. Vivid memories of listening to Alicia Quays on the DLR enroute to a gig in East London, then years later getting lost late night in NYC while listening to Carry on the Grudge.
Jamie T is a criminally underrated writer. He's a classic poet-singer and his influences range from English punk to garage, dnb, ska, and all kinds of stuff. He is endlessly surprising and always authentic.
I am so grateful to the inquisitive Import AI community - it brings me a lot of joy to highlight research in the newsletter and for it to generate meaningful interest
Looks like the surface area of the @jackclarkSF DM-saga is crazy and here's mine!
Back in 2019, I was miffed that no one was building ML datasets for Indic languages and took it upon myself to build Kannada-MNIST and put it on Kaggle. A few days later, I saw a deluge of interest and it turned out that Jack had written about my dataset in his newsletter "Import AI" with these golden words:
"Soon, we’ll have two worlds: the normal world and the AI-driven world. Right now, the AI-driven world is going to favor some of the contemporary world’s dominant cultures/languages/stereotypes, and so on. Datasets like Kannada-MNIST can potentially help shift this balance" 💀💀

Again, in 2021, I had gone down the rabbit hole of Computer vision's most influential and yet mysterious datasets called JFT-300M (youtu.be/TvVc1e_4648?si=oVC6… ).
It turned out that Jack was investigating it as well and DM'ed me a bunch.
I don't know I ever responded though 🥲
NGL, his story arc is one for the ages man.
The single most useful take I heard at The Curve was "we can still heist the Mona Lisa after the singularity". There's a subtle/important point here, where some things (e.g, n of 1 goods where originally is valuable) will retain/grow in value even as everything changes.
This is also just a straight up great writing prompt - what would it mean to steal something in a post-singularity future? Who is the team? What are the security systems? How do the police work? great stuff! Session was chatham house so I can't name who said it.
