Why can’t I shake the feeling that this supposedly “new” safety discussion is just being used as an excuse to postpone the IPO?
I agree with Dario that we need to pace the frontier. This has been a primary topic of discussions we've had at OpenAI in recent weeks. Committing to having independent evaluators with employee-like access is a great idea, and we will do the same. We'll have more to share soon.

Sounds hard-won: 24 debugging patches and 18 kernel boots were needed
This is a great real-world example of AI-assisted coding: Linus Torvalds just fixed a nasty Linux kernel GPU bug with substantial help from AI. The bug caused part of Intel Xe GPU compression metadata storage to be incorrectly exposed as usable VRAM, resulting in corrupted page tables and black screens. The eventual fix was basically a one-liner: round_up() → round_down(). Finding it was the hard part: 24 debugging patches and 18 kernel boots. Linus says AI did much of the grunt work, repeatedly adding debug code and analyzing the results as he narrowed down the problem. The funniest part: the AI repeatedly told him the problem was "impossible and unsolvable" and suggested giving up. Linus kept pushing it until they found the bug. And then he let the AI write the commit message. 😄

🛜 Remember LAN parties? I do LAN means "local area network" and it was essentially the internet but locally only in your home or company in the late 90s and early 2000s So you could connect to other computers to play games or share files, kinda like Airdrop but via a cable and 30 years ago, people would even meet up at some person's house and bring their entire computer (back then a big PC tower, CRT monitor, keyboard and mouse) and everyone would connect to each other Which is were you'd get all the WaReZ games, MP3 music, etc. cause nobody had internet yet, or if you did it was super slow, so LAN was much faster to transfer files I know Windows 3.11 did have support for LAN networking via NetBEUI and it "should" work, but of course on pieter.com I don't have a network cable that goes to an Ethernet network hub to other computers But...we could just act like we do? I asked AI to build a virtual Ethernet hub (a hub routes traffic) that acts like a local LAN, but instead of connecting physical computers in a home, it connects other browser sessions on the internet that have pieter.com running Windows 3.11 open at any time, and with DHCP it can assign an IP to every browser session dynamically, so they literally all become part of a local LAN on the internet! It runs on a virtual NE2000 network card that sends its network data not to a network cable but via Websockets to wss://pieter.com And it works, well kinda, I just started and its' not perfect, but I'm able to PING in MS-DOS from one tab to the other! Next is setting it up inside Windows 3.11!
🤓 Another interesting milestone I was able to connect the modern WebGL Quake 1 multiplayer at q1.pieter.com To my MS-DOS Quake 1 (from 1996) running on my virtual PC at pieter.com Here's the sequence: You move in Quake 1 -> WATT-32 TCP/IP stack package -> ETHERSL packet driver -> SLIP encode -> COM3 serial port -> Websocket wss://pieter.com -> pieter.com server-side SLIP-decode ->gets raw IP -> IP forward in Linux -> q1.pieter.com Quake server -> fteqw-sv64 receives package and moves other player

Got ahead of the pack a few weeks ago and snagged a Mac Mini. It's now running 24/7 as an AI server with @openclaw for my personal agent. Good thing I did Mac Minis are sold out everywhere nearby! Tim Cook just confirmed it: agentic AI demand is through the roof and supply won't catch up for months. 🚀 #OpenClaw #AIAgents #MacMini

The madness continues: now the smallest Mac Mini costs almost twice as much because the 256 GB version has been discontinued. Still not available until beginning of June.

Peter Steinberger is joining OpenAI to drive the next generation of personal agents. He is a genius with a lot of amazing ideas about the future of very smart agents interacting with each other to do very useful things for people. We expect this will quickly become core to our product offerings. OpenClaw will live in a foundation as an open source project that OpenAI will continue to support. The future is going to be extremely multi-agent and it's important to us to support open source as part of that.

🚀 How to get rich with OSS in 90 days We just watched history: a solo dev hobby project explodes to tens of thousands of GitHub stars in weeks, gets renamed twice amid trademark drama, hits Lex Fridman’s podcast, and sparks a wave of wrappers, SaaS layers, and acquisition chatter. @openclaw (ex-Clawdbot / Moltbot) didn't make Peter Steinberger (@steipete) billionaire overnight, but it created real wealth velocity: attention → community → wrappers/SaaS → exits/offers in < 90 days 💰 👉 The playbook that actually works right now: 1️⃣Pick a painful, timely problem in the AI/agent wave (local execution, privacy-first assistants, vibe-coding automation, etc.). 2️⃣Build fast & open-source day 1: MIT/Apache license, killer README, beautiful demo GIFs/videos. Launch on Reddit/Hacker News/X with zero gatekeeping. 3️⃣Ride the virality flywheel (GitHub stars, people fork/build on top, etc.) to get massive attribution, inbound leads, consulting gigs, sponsorships, or straight acquisition interest 4️⃣Invest own money or get sponsorship (e.g. GitHub Sponsors): up to $10k–20k/month loss on hosting, tokens, security, etc. 5️⃣Stack credibility fast: post daily progress threads, do AMAs, podcasts, let the community co-maintain But please remain realistic: almost all OSS are not commercially successful, 99% of OSS stays hobby-level 😮 Let's make some lobster money 🦞 Thanks @steipete, @sama and @OpenAI to keep us dreaming 👏 #OpenSource #AI #IndieHacker #SaaS #OpenClaw #SoloDev

Did you know that a small Israeli chip startup acquired by Amazon in 2015 for ~$350 million, Annapurna Labs, is the team behind the core architecture of AWS’s latest AI powerhouse Trainium3 ? Announced at re:Invent 2025, this third-generation training accelerator delivers up to 4.4× the performance of its predecessor, dramatically lower training and inference costs. The pressure is mounting on both Annapurna Labs and Anthropic as they close the gap with Nvidia. #AWSreInvent2025 @awscloud #AmazonAI #AI @AnthropicAI @nvidia

I moved to back to New York 17 days ago, and here are some thoughts on the lifestyle here: 1) Manhattan is a place with lots of very good food for a “holy cow, I can’t believe I just paid that much for dinner” kind of price. 2) Nobody moves to New York to take it easy in life, and that determines a lot of the dynamics of the city. It’s a place you move to be somebody or do something. It’s not a place to coast. Or in the words of Taylor Swift: “Everybody here wanted something more” and “Everybody here was someone else before.” 3) The biggest problem with the subway isn’t slow speeds but the variance in travel times. This was captured well in a New York Times: “The subway is so late, it’s making New Yorkers early.” Why? Due to the variance, people need to leave early enough to account for the unpredictability of travel times, and when the subway shows up on time, they end up being awkwardly early for work. I wonder: how much should we focus on speeding up the subways, as opposed to reducing variance in travel times? 4) The vibrant social life is a positive externality of crappy housing. In most cities, people are content to hang out at home. But in New York, it’s so easy to get stuck in such a dungeon that you’re desperate to escape. Because of that, people end up socializing more than they would if the living quarters were nice. 5) Whenever I fly into LaGuardia, I’ll look at the landing patterns before my flight so I can sit on the side of the airplane that’s going to fly in with the best view of Manhattan, where landing airplanes fly over the city at an altitude of 3,500 feet. If the winds are from the south or the east, sit on the right side of the plane. If they’re from the north or the west, sit on the left side. When in doubt, pick the right side of the airplane. 6) One way to think about a city is how much making more money improves your quality of life. When I lived in Austin, I didn’t see how huge increases in my income would improve (or even change) how I lived very much. New York is different. Quality of life here correlates much higher to spending power, and this is one reason why New Yorkers are so intensely money-motivated. 7) Let’s use my first three apartments as an example. Each move was an upgrade not because I got more square footage or natural light, but because I wouldn't have to deal with as many mice. In my first place, I saw one every month. In my second, a few per year. By the third, they were gone entirely. And yet, through all that time, I swear I was paying more for rent than I would’ve paid for a mortgage almost anywhere else. 8) It’s much easier to get a good date in New York, relative to other American cities (and this is driven by the female-heavy gender dynamics). 9) Notice, though, how my emphasis was on the ease of getting dates in New York, for men at least. People here complain about the lack of commitment, and the sense that there’s always something (or someone) better right around the corner leads to that lack of commitment. 10) What New York gives you in volume of friendships, it lacks in depth. Of course you can cultivate deep friendships in New York, but I’ve found that the default mode is to be constantly meeting new people at the expense of seeing the same people over and over again. Mitigating this requires constant effort. 11) One of my friends is a tour guide who says there are six decisions that made Manhattan great: (1) the water system of 1842, (2) no steam engine trains south of 42nd street, (3) no steam engines in tunnels within the city limits, (4) no overhead powerlines, (5) the landmarks and preservation committee, and (6) Manhattan’s grid. All these are good rabbit holes to follow if you want to understand its history. 12) I agree with the first five, but have mixed opinions about the grid. Yes, it brought order and efficiency to Manhattan. And yes, it makes it easier for anybody (and especially people who don’t speak English) to navigate the city because they can deal with numbers instead of names. But I prefer the street life below 14th street, where the streets are narrower and more chaotic. Based on real estate prices, I’m clearly not alone. 13) New York will always have a monopoly on a certain flavor of American life: don’t own a car, walk most places, bike a lot, and have an abundance of restaurants and nightlife within a 1-mile radius — while also being an economic hub. There’s only one city in America where that combination exists, and it’s New York. 14) Something to know if you want to better navigate Manhattan: Even addresses on the south side of the streets and the east side of the avenues, odd addresses on the north side of the streets and the west side of the avenues (except for below 14th street where the grid breaks down). 15) As much as I enjoy the materialistic aspects of New York, I find spiritual life here to be incredibly challenging. There’s so much temptation and so much distance from nature, and the speed of the city makes it hard to cultivate the kind of stillness you need to hear from God. 16) Always, always ask: “Why is it called that?” For example, the name ‘Manhattan’ means “island of many little hills.” There are two things to take from this. The first is that Manhattan really is more hilly than you’d think. But at the same time, for a place of that name, it’s surprisingly flat because New Yorkers dynamited most of the hills away. Whatever hills remain are now man-made skyscrapers, not God-made land. 17) People make fun of New Yorkers for praising the new bike lanes, but the excitement people have about them is a reminder that if you want to improve street life, you just need to get rid of cars and give people cozy places to walk. That’s how low the bar is for urban design these days. 18) An easy way to improve your quality of life in New York is to build the habit of ordering ahead whenever you go to a take-out lunch spot. The restaurants in town make it easy to order ahead now in ways that weren’t possible a decade ago (and because of TikTok, the lines are as long as they’ve ever been). 19) Somebody on here said something recently that I can't stop thinking about. I've lost the tweet but it was something like: "TikTok is doing to New York what YouTube did to Los Angeles ten years ago." 20) New York has a way of feeling like it’s the entire world like no other city I know. One of The New Yorker’s most famous covers is about exactly this (see the photo below). 21) As much as I enjoy the materialistic aspects of New York, I find spiritual life here to be incredibly challenging. There’s so much temptation and so much distance from nature, and the speed of the city makes it hard to cultivate the kind of stillness you need to hear from God. 22) New York and San Francisco have different ways of thinking about work-life balance: In New York, you work your tail off when you’re at the office, but it’s relatively easy to disconnect on the weekends. In San Francisco, even though I don’t sense the same temptation to work so hard that you have lunch at your desk, there’s a way your job dominates life more there. People take company buses to / from work, tech companies have gyms inside their HQ, and even the weekend social events feel work-related (even if you’re technically off work). There’s a reason that a book like The Circle takes place in the Bay Area, not New York. 23) New York is a cultural and economic capital, but not a political one. That seems obvious now, but it wasn't inevitable. New York was once the capital of the United States. And if Washington hadn't taken that title, New York would be a far more political city that's more tethered to the past and filled with military statues.

I’m building an 8-K parser this week. Unlike annual reports, 8-Ks are not standardized by the SEC. We have to parse them on our own. Initial approach: • parse the filing • extract the sections (Items) • classify with LLMs Diagram shows high-level. All code will be open source. Let’s build.
