OpenAI’s Navier-Stokes release included a Lean 4 formal proof
2 min read
Yesterday OpenAI announced a proof that settled a long-standing question about the Navier-Stokes equations from fluid dynamics. The announcement has created a lot of buzz, as one would expect. But there’s an aspect of OpenAI’s work that I haven’t seen anyone talk about: they posted a Lean 4 formal proof at the same time as their conventional human-readable proof. Quite a few other mathematical con...
Proof of Capture: Apple Reference Image, but open source and using steganography
3 min read
Apple Reference Image, but open source and using steganography Apple introduced yesterday Apple Reference Image: a way to cryptographically prove a photo was actually taken by a camera, instead of AI generated. During my time at the Recurse Center this summer, Alex Hornstein and I (two camera lovers) built a camera with proof of capture. Prove what’s real at capture time Back in 2019 I was deployi...
OpenAI Agents API

Build durable cloud agents with a managed Codex harness. The Agents API gives your application access to the Codex harness through an OpenAI-managed API. OpenAI manages sessions, orchestration, context compaction, and recovery while your application provides tools and chooses its execution environment. Agents can operate in a sandbox where they can execute code, edit files, connect to MCP servers,...
Creativity is the new moat
12 min read
AI makes it fast and easy to copy what’s already out there. If you build products or run a business, your competitive edge is not necessarily features or price, it’s ideas. This means getting in the habit of inventing new things is more valuable than ever. And to explain how, let’s look back at a strange time for the web: the era of Flash. Back in 2006, I worked at a tiny creative agency called Mu...

AI Is Breaking This Thing We Call Trust

I want you to picture yourself in the early 1900s (in America), real quick. People have been using horses for their entire lives, and they are pros at it. Entire cities are actually built with the premise that horses are how we move from point A to B. Then this Henry Ford guy shows up and turns the world upside down. Over the next few years, people had to adapt to cars becoming part of everyday li...

Shopify moves back to Native from React Native
10 min read
We decided to go all-in on React Native back in 2020, and that bet has been extremely successful. We saved a ton of time building features just once, enabled developers with no mobile background to contribute to our apps, and freed ourselves from constantly chasing feature parity. In January 2025, I wrote that the future of React Native was bright and that Shopify planned to keep investing in it. ...

I think I hate the internet I’ve just finished reading Careless People by Sarah Wynn-Williams and was equally parts shocked and unsurprised by the events she witnessed at Facebook / Meta.

BREAKING: OpenAI might have stolen another major proof. In a detailed Mastodon post, which I report in full in the comments, Andreas Thom presents several pieces of evidence suggesting that OpenAI may have trained Astra on conversations in which he and Gábor Kun were working on Gromov’s soficity conjecture, one of the ten problems OpenAI later announced Astra had solved. I know Andreas. We met sev...

Training a 3.8B LLM to 0.384 CORE for $998 Somewhere between “nanoGPT toy” and “you need a research lab” there’s a large, under-described region where one person with a few thousand dollars can train a meaningful model.

A Stupid Idea for AI Alignment We Came with by Looking at Specification Gaming

Creatures bred for speed grow really tall and generate high velocities by falling over. An evolved player makes invalid moves far away in the board, causing opponent players to run out of memory and crash. A game-playing agent accrues points by falsely inserting its name as the author of high-value items. These bizarre exploits and dozens more can be found in the list of specification gaming behav...
I'm sorry, you're not going to die from an AI-engineered supervirus

Opinion writer and economist Noah Smith just dropped an article about AI-designed superviruses. Oh man. I used to think Smith was a person with informed opinions, but reading his take on a topic close to my own expertise makes me question this premise. No worries though. I’m sure I’ll read his takes on inflation tomorrow and nod along. Gell-Mann amnesia is real. The article opens with a fictitious...

Anthropic Is Building AI to Predict Which Activists Police Should Watch. SF-based AI lab pays up to $230,000 for intelligence analysts who formally categorize activism as a threat alongside terrorism and nation-state attacks
3 min read
Dario Amodei, Anthropic’s CEO, has a theory about why people distrust AI companies. “Ordinary people don’t trust companies, governments, or the tech industry,” he said recently, “and always suspect that we are cooking up some new way to screw them over.” He’s right about the distrust. What he left out: Anthropic has reportedly built a predictive security operation that formally classifies those sk...

Growing proof that autonomous cars save lives
5 min read
Plenty of people remain spooked by autonomous vehicles, or AVs. Some experts and policymakers have cautioned that AVs won’t necessarily make roads safer. When it comes to partial or full autonomy, the picture isn’t entirely clear, in part because there aren’t enough self-driving cars to make meaningful apples-to-apples comparisons. Yet mounting research suggests that self-driving cars crash signif...

Is OpenAI Taking Everyone for Fools?

OpenAI claims to have solved a decades old mathematical problem just as researchers are about to publish their solution. Coincidence?

Defining AI Psychosis. Part 2: "Prolific AI Psychosis"

Last week, I suggested that the term AI psychosis is applied to at least three different situations: 1) Genuine psychotic experiences related to LLM use, a phenomenon I described as “true AI psychosis.” 2) Hyperengagement with AI tools that is accompanied by a softer disconnection from reality. I’m calling this “prolific AI psychosis.” 3) Maladaptive relationships with AI chatbots that mimic human...

GPT-6 Astra, looped transformers, and hidden reasoning

A lot has happened in the last few weeks. I am sure that OpenAI’s GPT-6 Astra is top of mind for everyone right now. In particular, thoughts on its performance, the looped transformer/recurrent depth aspects, and rumors that Astra is “hiding” its reasoning trace (i.e., chain of thought). So, in this article, I want to start with some brief impressions of Astra and some thoughts on where all this i...
