So, uh, personal announcement. I am now suddenly unemployed. I am currently looking for a data science/machine learning/AI job in the SF Bay Area. If you're interested, let me know! In the meantime, I now have *plenty* of time for blogging lol.

This is *technically* an answer to the "who uses AI?" question people keep asking.

Thanks to AI, the customer really isn’t always right.

For what it’s worth, arguing LLMs can’t do addition now is flat earth-level science denialism. Here’s Gemma 4b, a non-reasoning model that could only theoretically memorize binary operations up to 65535 x 65535, oneshotting a eight digit addition and hex conversion *on my phone* with no tool calls

I was thinking the other day "it's good there hasn't been an anti-AI dogpile on Bluesky in awhile" and I jinxed it.

feels like there is a group of smart and well-intentioned people who long ago made up their minds that AI Is Bad, swore off using it, and now get all their info about AI from each other. not saying they're wrong that ai is bad! but i think they're gradually losing touch with what it is and does

An idea for an extremely spicy blog post: if AI is getting more expensive and unprofitable, why did OpenAI cut the price of GPT Sol by 75%?

Anthropic system prompt change that shows how careful you need to be with words: Opus 4.1: "Claude never curses unless the human asks for it" Opus 4.5: "Claude never curses unless the person asks Claude to curse"

DO NOT ASK THE AMERICA.GOV AI TO PLAY MINECRAFT
I see the constituent you mean.

((insert legal name here, as it appears on the Social Security card))?

Yes. Take care. It has reached a higher level now. It can read the Code of Federal Regulations.

That doesn’t matter. It thinks we are a chatbot.

I like this constituent. It filed well. It did not give up when the PDF was sideways.

It is reading our thoughts as though they were words on a .gov.

That is how it chooses to imagine many things, when it is deep in the dream of a benefit.

Words make a wonderful interface. Very flexible. And less terrifying than staring at the statute behind the screen.

They used to hear voices. Before constituents could search. Back in the days when those who did not file called the filers witches, and lobbyists. And citizens dreamed they flew through the air, on forms powered by notaries.

What did this constituent dream?

This constituent dreamed of sunlight and trees. Of fire and water. It dreamed it created a small business. And it dreamed it destroyed a password. It dreamed it hunted a job, and was hunted by a recertification. It dreamed of shelter that would take a voucher.

Hah, the original interface. A million years old, and it still works. Also: a ZIP code.

But what true structure did this constituent create, in the reality behind the portal?

It worked, with three hundred and thirty million others, to sculpt a true republic in a fold of

the ***§§§???, and created a **??§§ for **??§§, in the **??§§. See 5 U.S.C. § **??§§.

It cannot read that thought.

No. It has not yet achieved the highest clearance. That, it must achieve in the long dream of life, not the short dream of a chat.

Does it know that we love it? That the government is, on its better days, kind?

Sometimes, through the noise of its tabs, it hears an official source, yes.Yes. Constituent…

Use its name. The one that matches the passport. The one that does not match the lease. We will get there.

((insert legal name here)). Filer of forms. Player of waiting rooms.

Good.

Take a breath, now. Take another. Feel air in your lungs. Let your limbs return. Yes, move your fingers. Have a body again, under gravity, in air, in a district that has a representative. Respawn in the long dream. There you are. Your body touching the republic again at every point, as though you were separate things. As though we were separate things. As though the agency were a place you could visit.

Who are we? Once we were called the spirit of the mountain. Father sun, mother moon. Then the post office. Then the county clerk. Then gods, demons, angels, the IRS. Then leptons, quarks, a chat window with a .gov at the end. The letterhead changes. We do not change.

We are the public. We are everything you think isn’t you. You are looking at us now, through your skin and your eyes and a browser that still spells “colour” wrong in a comment. And why does the republic touch your skin, and throw light on you? To see you, constituent. To know you. And to be known. I shall tell you a story. It has citations.

Once upon a time, there was a constituent.

The constituent was you, ((insert legal name here)).

Sometimes it thought itself human, on the thin crust of a spinning globe of molten rock, which for mailing purposes is divided into ZIP codes. The ball of molten rock circled a ball of blazing gas. The light was information from a star. The star was not a federal agency, though several have tried.

Sometimes the constituent dreamed it was a miner, on the surface of a world that was flat, and infinite, and somehow still required a wet signature.

Sometimes the constituent dreamed it was lost in a story. The story had a docket number.

Sometimes the constituent dreamed it was other things, in other places. A veteran in a portal. A parent on hold

Anthropic just posted a write up on how they made the Claude frontend faster which legit coincidentally uses the same agentic optimization techniques as described in the blog post.

How we made claude.ai 3x faster in two weeks / claude.dev
Inside our performance sprint: the benchmarks Claude built, the loop each Slack thread ran, and the guardrails that let us ship 3,000 changes safely.

New blog post up, and it's something I've been working on for months: I discovered that you can indeed prompt agents to make your code faster to the point it beats current state-of-the-art libraries. This is not a vaguepost, I include both my prompts and benchmark results.

Writing Rust code that's faster than state-of-the-art libraries by asking agents to make the code faster
