People outside the AI labs should have a real say in how this technology develops, and a clear way to judge if it's happening safely. Standards should help prevent the concentration of power, including by making sure new companies and open-model companies can compete. They shou…↗

Introducing The Horowitz Andreessen Academy.↗

Opus 5 (or Opus 5.5) built a scroll site for a heavy transport company with some great animations in oneshot! Took one prompt and I took some inspo from the website unitedcarriers dot com if you wanna check it out: axis-haul.vercel.app↗

We spend a lot of time building on the canvas. We write a lot about it, too. In the thread below, a few recent pieces from the archives on AI, agents, and spatial software:↗

My job at @every is basically benchmarks-as-a-service now: every.to/also-true-for-…↗

how to improve GPT-6 Astra / Codex's ability to design and code websites I've been using this approach since GPT Image was released, and the results have kept improving with 2 and 2.5 the idea is to have Codex generate visual mockups of the website before building it, whether y…↗

Meet Husky: a Model-Specific Inference (MSI) engine up to 4.5× faster than Apple's MLX Woof, Underdog's Pareto frontier model, now runs up to 730 tokens/sec on a MacBook Finally local models are as fast & capable. Try it now in underdog.ai - your personal private AI↗

Put together some notes on Jev and the new category of system one aka decision models simonwillison.net/2026/Sep/21/je…↗

I now type "use big pictures and few words" several times a day↗

The addressable market for Decision models like Jev might be very large Chart from openrouter.ai/rankings#task-…↗

here's how i shipped 2,500 PRs last month to production this was originally supposed to be for Cursor Compile in London. i couldn't make it since i was livestreaming for Grok @Bot Galaxy so i'm making it available for free here on X! watch it on 2x speed, i talk slowly↗

We’re working with an independent advisory group of mathematicians to help OpenAI responsibly share advances in AI and mathematics. The group will advise on how we assess and communicate new mathematical results, uphold academic and professional standards, and build tools that s…↗

we built muse from scratch, but it is definitely heavily inspired as a product by openclaw. After I used openclaw in january I bought hundreds of mac minis for the MSL team and lots of us fell in love with using openclaw (and other personal agents). @steipete is a genius and his…↗

Here's how I run my software factory: 1. During the week, I collect ideas + inspo. 2. On the weekend, I give the list to an agent to rank the best ones. 3. I spin up ~5-10 parallel agents to build POCs. 4. I kill ~60%, iterate on the better ones, and end up with 2-3 solid demos.…↗

Dumb question - how is Amazon going to be able to tell if it's a human or AI accessing it assuming it's coming from the human's IP address?↗

every major company is arriving at roughly the same offering: persistent memory, email/calendar/messages, browser + computer use, background tasks, proactive notifications, voice, app/tool execution, ambient context, & some notion of a personal agent sitting above everything.…↗

We are excited to announce we are partnering deeply with Muse to enable agentic checkout with Shop Pay on all Shopify stores, offering people an easy and delightful way to shop and check out with Muse.↗

Grok 4.7 is here. It's a notable improvement over Grok 4.6 at the same price and speed.↗

my current agents.md that made astra work well still a work in progress, i keep tweaking it try it out and see how it works for you↗

The problem with all of these AI personal assistant things is that people don’t actually want to do stuff. You fucking get that right? Do you understand that? Just like AI tools in the workforce, AI assistants don’t actually abstract decisions for you, they let you accelerate…↗

Have a question? Ask Jev AskJev.net↗

Jev is incredible. I'm scared people are using it wrong.↗

sharing some notes on typesafe 🤝 coding agents: docs.google.com/document/d/1G6… we likely will never have time (ever again) to play ourselves, but hope the that the community goes WILD (and makes me look like a naive idiot)↗

@jamesm If you ask your mom "is the sky blue" she says "yes" immediately, that's jev. If you ask your dad "why is the sky blue" he talks for ten minutes, that's an LLM.↗

介绍比Jev快50倍，在你设备上跑的laya-mlx! 只在你的设备上占用最高1G内存 Laya是一个开源的类似于Jev的,基于文本输出概率的分类系统 我将其移植到MLX,并且做了一些性能优化! 视频中就是这个模型在我的本地M3Max上玩贪吃蛇 这个模型能够以每秒决策60次的速度玩贪吃蛇！ github.com/mizorewww/laya…↗

The best way to learn something is to build with it! I built Jev Explained with 4 examples that show what Jev is, how its primitives work, and how to use them in practice Clone the repo, open Claude Code or Codex, and ask it to create a new example using the existing codebase a…↗

Introducing a new way FIND (⌘F) with @typesafeai Jev. Find what you mean, not what just matches. Super fast and near real-time. Made it 100% open-source chrome extension.↗

The life of a button... 🔊↗

Quite an interesting turn in LLM diversity, if the market starts looking for specialized models that are optimized and branded for different use cases. Should be very good for the market and open more room for non-frontier neolabs!↗

Running Jev to see how fast it can remove negative comments from chat↗
