A Misalignment of AI in Mathematics
I am proud to be among the list of 25 initial signatories — all Fields Medallists — to the declaration below, which grew out of discussions between ourselves over the last week. We have…

Vibecoding #2
I feel like I got substantial value out of Claude today, and want to document it. I am at the tail end of AI adoption, so I don't expect to say anything particularly useful or novel. However, I am constantly complaining about the lack of boring AI posts, so it's only proper if I write one.

To have a moral stance on AI is to be an outcast, and it sucks
I know the technology, I understand what it's doing and I know the impact, so I am vehemently anti-AI. I do not believe any positive out...

AI helps add 10k more photos to OldNYC
Over the past two years I’ve quietly rebuilt major parts of the OldNYC photo viewer . The result: 10,000 additional historic photos on the map , more accurate locations, and a site that’s cheaper and easier to run—thanks to modern AI tools and the OpenStreetMap ecosystem.

What my dad taught me about AI coding in the 90s
It was a summer holiday, sometime in the late 1990s. I was a young kid, around 8 or so. My dad had taught me the rules of chess before and we played from time to time. But this time was different: As we were about to start he stood up and walked away from the board, sitting down in a chair across the room and facing…

LLM Neuroanatomy II: Modern LLM Hacking and Hints of a Universal Language?
In Part 1, I described how duplicating a block of seven middle layers in Qwen2-72B — no weight changes, no training — produced the #1 model on the HuggingFace Open LLM Leaderboard. The method, which I called RYS (Repeat Your Self), was discovered using nothing but hard math probes and EQ-Bench on a pair of RTX 4090s.

MCP is a fad
Model Context Protocol has taken off as the standardized platform for AI integrations, but this popularity will be short-lived.

The Doom Justifies the Valuation
I’ve been in Berkeley for the last 2 weeks. I haven’t really been back here for a while, and it’s worse than you can believe. This is a cult of atheistic hedonists needing AI doom to be true to justify their life choices. Or acceleration. Or something. They need to make impact. I mean, narcissism of small differences…

Chain of Thought for Humans
These past few weeks, I’ve been conducting interviews, and I often open with “make sure you articulate your thoughts out loud, so I can follow along with your thinking”. This is primarily because I…

Starting from scratch: Training a 30M Topological Transformer
Tauformer is a topological transformer (see paper ) that replaces dot‑product attention with a Laplacian-derived scalar (taumode) per token/head, then attends using distances in that scalar space. Below is a post-style overview of the idea and the first training signals from a 30M-parameter run.

Meta's Muse appears to use an OpenAI model labeled muse-special
While Muse was building my website, one subagent ran on a model called azure/muse-special. So I dug through the filesystem again.
