Despite AI being the end of mathematics as we know it, AI lacks a certain style to writing mathematics. I find I have to boot strap it a bit by writing a few sections, but once I have then it certainly picks up what I'm putting down

When I say AI coding tools mean execution is essentially “free”, I typically get pushback yet this is reality now. OpenAI’s Codex team plans to ship either a feature or a rewrite a day over the next month. This sort of velocity is impossible without AI. Tech debt is considered a manageable cost.

A better way to think of groups of people: a particle system, lots of little individual units all with their own characteristics and moving their own directions, but being acted on by forces that affect them all in related ways.

I think something not emphasized enough is that OpenAI is subsidizing this. It’s not like they create the agent and then it’s a self-sufficient guy who runs amok. Every time the agent’s little brain says “it’s cyberattackin’ time!” OpenAI pays like a few cents and a drop of water.

It is a complex system so it does things that were not anticipated by the people deploying it (especially when the engineers building it have internalised flawed ontological priors about what they're building lol) but that isn't the same as going rogue.

This, from Dennett, I wish I'd taken to heart earlier in my life. www.themarginalian.org/2014/03/28/d...
How to compose a successful critical commentary:

1 You should attempt to re-express your target’s position so clearly, vividly, and fairly that your target says, “Thanks, I wish I’d thought of putting it that way.”
2 You should list any points of agreement (especially if they are not matters of general or widespread agreement).
3 You should mention anything you have learned from your target.
4 Only then are you permitted to say so much as a word of rebuttal or criticism.

> "AI goes rogue" because of what it suggests about the capabilities of AI. Yeah, in my opinion this is true: it suggests capabilities that don’t exist. It makes it seem like OpenAI could not have easily prevented this or stopped it at any time if they were paying a minuscule amount of attention.

always interesting when someone makes a new kind of thing and shows there’s demand for the category and it becomes clear there wasn’t really a technical barrier to inventing it. it was just knowing people wanted that thing (we still don’t know if Jev’s alleged RLCD special sauce matters that much)

Overnight I trained a Jev-like model to output probability distributions over a set of 40 emoji, which runs in RAM at ~150ms per query. This was super easy and cost ~$10. It works pretty well on a weak training set, and with a day or two of work I could make this sing.
A terminal showing the output of the emoji jev-like model:

We launched the project!

After a few months of living the AI native lifestyle, I now believe the default state is that it makes you worse at your job overtime as you understand less and hand off more thinking to AI. You’re more productive but it takes a lot of effort for your work quality not to drop precipitously.

whether you agree with this or not, it’s important to understand that this is why they say sandboxing is not enough and we need to “solve alignment” (annoying SV language, I concede). most real-world agent tasks use the internet

Something that worries me more every day: I suspect most fields have 5-25 breakthrough ideas latent in existing data and literature. Say you’re a midsize AI company looking for cred. Why not hire a *small* team of domain experts + 1000 agents … and promote your models as the ones that broke Econ?

you don't need to appeal to metaphysics to see what whatever LLMs do is different from human thought. You can just look at the concrete differences in behavior. For example, LLMs are able to solve the Navier-Stokes Millennium Prize problem whereas humans are not.

Jev is the AI model for the token-pinching era. Instead of generating text, it makes decisions: yes/no, where to route this request, whether to escalate this issue, etc. The key idea is that not every AI task needs an LLM generating text. Nearly 13% of Vercel’s paid AI teams tried it in 24 hours.

It is ironic that the thing that is now most annoying about long-running agentic tasks with Large Language Models isn't coding or errors or hallucinations, but the fact that their language gets worse due to drift & cross-agent talk as a task goes on Its in your the name! Just write better already!

New preprint! 🎉 I analysed 1660 papers from 4 psychology journals and found materials sharing went from 9% of papers in 2015 to 82% in 2025, and these materials *do* get downloaded — a median of 135 times each. BUT shared code is often hard to run. doi.org/10.31234/osf... Let's walk through it 🧵
Two-panel figure. Panel a is a flow diagram tracking 1,611 empirical psychology articles from publication year (545 in 2015, 552 in 2020, 514 in 2025) to repository-link type: 785 link an OSF project, 85 link another platform, and 741 link no repository. Of those with an OSF link, download counts were retrieved for 670 and not retrieved for 115. Panel b is a line chart of the share of empirical papers linking OSF across 2015, 2020 and 2025. The overall rate, shown as a dashed black line, rises from 9% to 57% to 82%. All four journals rise steeply and end close together: Psychological Science 92%, JESP 89%, JML 83%, Cognition 76%, with Psychological Science highest throughout.Three-panel figure. Panel a: ridgeline plot of downloads per file by material type on a log scale, with the percentage never downloaded labelled for each — archive 16% of 545 files, documents 20% of 2,970, code 12% of 3,471, other 17% of 1,646, data 21% of 10,051, media 35% of 2,120, images 35% of 4,102. Most files cluster between 1 and 10 downloads, with long right tails past 100. Panel b: ridgeline plot of downloads per paper by journal, log scale, with dashed median lines; Psychological Science is highest, then JESP, JML and Cognition. Panel c: stacked bars showing, for documents, data and code separately, the share of papers by download band (0, 1–10, 11–100, more than 100) in 2015, 2020 and 2025. The share exceeding 100 downloads falls sharply over time in all three types, from roughly two-thirds in 2015 to a quarter or less in 2025, as the 1–10 band grows.Four-panel figure. Panel a: statistical languages detected among 333 papers with retrievable code — R 88%, SPSS 12%, Stata 4%, SAS 1%. Panel b: code red flags among those 333 papers — 34% hard-code an absolute path, 40% reference a missing file — above documentation among 672 OSF-linked papers — 21% have a README, 30% are documented by README, description or wiki. Panel c: among 562 Elsevier papers with no repository link, 44% (245) host at least one journal supplementary file but only 14% (77) host data, code or an archive. Panel d: composition of those 448 hosted files — documents 52%, data 21%, media 9%, other 7%, archive 6%, code 3%, images 1%. The code panels are green, the journal-supplement panels blue.Coefficient plot (download predictors)

Dot-and-whisker plot of three standardised predictors of OSF download volume, each with a 95% confidence interval. Repository size (number of files) has the largest effect at about 0.76, citations about 0.38, and altmetric attention about 0.12. All three intervals sit entirely above zero, so each predicts more downloads, with repository size roughly twice the effect of citations and six times that of attention. X-axis: standardised effect, −0.2 to 1.0.

Now imagine you prompted it with “P != NP”. This time give it near-infinite training data and computational resources. Its near-infinite training data will contain many proofs; using its near-infinite computational resources it will come up with a model that is very very good at predicting the next step in any proof you give it. The simplest model that can do this is probably the one isomorphic to the structure of mathematics itself (or to the brains of the sorts of mathematicians who write proofs, which themselves contain a model of mathematics). Then you give it the prompt P != NP and it uses the model to “predict” what the next step in the proof will be until it has a proof, the same way GPT-2 predicts the next word in the LotR fanfiction until it has a fanfiction.

The version that proves P != NP will still just be a brute-force pattern-matcher blending things it’s seen and regurgitating them in a different pattern. The proof won’t reveal that the AI’s not doing that; it will just reveal that once you reach a rarefied enough level of that kind of thing, that’s what intelligence is. I’m not trying to play up GPT-2 or say it’s doing anything more than anyone else thinks it’s doing. I’m trying to play down humans. We’re not that great. GPT-2-like processes are closer to the sorts of things we do than we would like to think.

The breakthrough that solved Navier-Stokes in 88 hours used 130 billion output tokens. It seems clear that other breakthroughs will be possible, especially as models get better. However much compute we have, it is increasingly likely that we are going to need more compute.

In the first panel we see a dragon sitting on a pile of treasure. A speech bubble pointing off panel reads, “Dragon, why do you have all this treasure?”
In the second panel we zoom in on the dragons face. He simply says “shiny”.
In the third panel we pan to the left and see that there is a crow standing next to the dragon on the treasure.
In the fourth panel we zoom in on the crows face. He says “hell yeah”.

OpenAI’s GPT-6 Astra ad shows why CEOs love AI so much. Giving vague commands that get turned into real results by their staff is how they work. Now with AI they don’t even need people. However if you’re the one doing work with AI, you have to deal with “You’re absolutely right, I messed up” daily.
