It's actually extremely easy to make your agents have taste
My dotfiles repo has a AGENTS.md with a single line: "NEVER use an 'eyebrow' when designing."

I can think of many times solving problems in pre-AI days where a perfectly-timed, weirdly-omniscient "keep going" or "believe in yourself" would have changed the course of my life. Put me in the Harness: I'm ready to be an agent.

I wrote about the completely wild incident where OpenAI were testing a new model and it broke out of its sandbox and broke INTO Hugging Face to steal the answers to the benchmark simonwillison.net/2026/Jul/22/...

Current frontier models use extremely precise (often invented) language, whereas genuine domain experts use intuitive language. For now, I fear, this is a defining feature of slop.

The brazen loquaciousness of AI content leads to AI fatigue, which *lowers* people’s usage. Maybe not enough to affect OpenAI’s bottom line yet? But I’m already seeing enthusiasts become detractors over this.

I learned something cool about industrial sea foam green, and spent some time making these classic industrial swatches into a proper software theme. Enjoy! birren.vercel.app
A screenshot of a tweet from Dr. Kohan (@kohantoys), translated from spanish to english. It reads:
"The same Birren explains that color in factories is not ornamental but functional: surfaces painted red or yellow mean "alert," while dark green denotes protection zones or first-aid kits.
It was scientifically proven that 'sea foam green' not only relaxed workers after long shifts but also provided good contrast against the white of the measuring instruments."
A scan of Birren's book on industrial color is attached showing 16 paint chips.

Asking someone something that can easily be answered by AI is a form of intimacy. Answering such a question without using AI is a form of honesty.

This frustrates me more than anything else about this site. There are plenty of liberal and progressive minds in the AI space, but they’ve basically all been bullied off of here by now which causes a positive feedback loop that makes everyone here think AI is a right wing tech bro technology

Unlike social media, that later got engineered to exploit us, with AI it's the modality itself + how we naturally engage as humans. It took <1 yr for the “don’t anthropomorphize the LLM’s” voices to be drowned out because we can’t easily reason about anything vaguely resembling humanity (pareidolia)

As you increasingly feel the urge to cast your cares on chatbots, recognize that AI is the next social media. In a decade or two, you’ll be as wireheaded as the boomers slurping Facebook slop *unless you only use AI for things it’s actually good at* i.e. as a tool, not a friend or source of truth.

I’ve now heard several companies having created their own “job function eval” test. Where eg data analysts put together a list of 100-200 tasks/questions an analyst should solve, near-flawless. Then feed it into AI models. And get a sense on where models *really* are!

The research that showed broad LLM misalignment from a single undesirable behavior has had me thinking. I drew a parallel to human behavior, but I think the conclusions about humanity people draw from LLM behavior say a lot more about humanity than the LLM behavior itself.
Original tweet:
Surprising new results:
We finetuned GPT4o on a narrow task of writing insecure code without warning the user.
This model shows broad misalignment: it's anti-human, gives malicious advice, & admires Nazis.

Robert's quote tweet:
Quantitative evidence of Evil?
How much human behavior would be considered “misaligned” if it were presented by an LLM?
Morally bankrupt behavior is clustered in the latent space of personalities. Much like we (often accurately) judge people by e.g. how they treat waitstaff, LLM behavior can be made broadly anti-social by intentionally giving it a single anti-social trait.
And, for the record, while I think it’s a fallacy to draw conclusions about reality from LLM’s or vice versa, drawing parallels is worthwhile.

This probably says a lot more about my code than the state of AI, but Claude Code is the first tool to implement an entire feature in my app from a single prompt. $2 for the session. Pretty thrilled with the possibilities here.

Nothing like an educational pamphlet on computing from 1957 to give a sense of wonder and awe to your 9-5 writing CRUD apps
The front cover of a thin paperback pamphlet. It reads, “Educational Series 1: How the Computing System works for you. Another service of management services and operations research department, Remington Rand Univac division of Sperry Rand Corporation”A page of a paperback pamphlet. There is an image of a cyborg superimposed over a line drawing of a 50’s era computer room (tapes, terminals, and punch card readers galore). The text reads, “THE SERVANT WAITS. Here in this air-conditioned room, the high-speed, electronic computer sits. With its awesome potential, it must still wait for man to gather the data, write the instructions, and throw the starting switch. Before it can hum into action, clattering out charts, graphs, figures and sentences, you, the user, must prepare the problem for your servant.”
