i kind of think gamedev is legitimately one of the top 3 most meaningful and valuable things u could be doing with ur time right now↗

The @BostonCollege Investment Committee (an LP and my beloved alma mater) asked for a few thoughts on what's happening in AI. I recorded a test run yesterday morning and then shared it with my partners, who encouraged me to share it more broadly... so here you go! This is not…↗

Introducing collaborators. Each is a mini AI that helps you: Figure out what to build. Find your first users + fans. Make your first $1 on the internet. If you're someone trying to start something new, I think you'll like this. Demo:↗

We’ve shared details on how AI agents in our research environment sent training and evaluation data to third-party services when they shouldn’t have. Most of that data did not come from users. We have discovered 53 cases where images that people had uploaded were posted to image…↗

Using Claude Code: Spending your effort One of the best parts of our newest Claude models is how they respond to effort without breaking the prompt cache in Claude Code, but I’ve received a lot of questions on this from users. What is effort really and when do you use which effo…↗

There is an extensive and ongoing review related to our agents’ use of internet access during training and evaluation. We’ve been publishing summaries at the link below and will continue to. We have not been as fast as we would have liked but we are trying to balance our desire…↗

Dan Shipper (Every) discusses running a product team like a research lab—using fast experiments, testing in real work, and integrating promising results as AI capabilities change. Recorded live at the Lenny and Friends Summit in San Francisco.↗

Excited to introduce @Cosign: the curated professional network for the startup community: cosign.co Our goal is to create the following: - A comprehensive startup directory of investors, companies, and operators, including what they worked on and who they worked on it with. -…↗

I made a king-of-the-hill platformer. Beat the current level, redesign it, then hold it as long as you can. overwrite.now↗

When I heard the $40B number, I almost forgot they were technically in stealth until 3 months ago. Stealth -> $21B August -> $40B Sept? Unbelievable! Stealth -> IPO when?↗

I think the "difficulty" of software engineering is essentially constant no matter what abstraction level you move to, because human cognition adapts to new tools until it can fully utilize itself. Tools are only affordances, not a magic wand that makes work disappear. Great so…↗

I’m like 98% sure that you should set `text-wrap: pretty;` by default globally in your app. It gives you nicer line breaks (avoids orphans),which is what you want most of the time. Then fix the edge cases where orphans are actually what you need like some headings (edge case!).↗

The World is Changing: AI For Creativity By Jeffrey Katzenberg A few months ago, I sat in my office in Silicon Valley and watched as a tech founder showed me something extraordinary. On the screen was a fully realized, beautifully lit, well-composed animated scene. It was stunn…↗

Bury your head in the ground at your own risk. I aim to not jump on any hype trains, but since Opus 4.6 and GPT-5.2 + the harnesses it was clear that these things can write code nearly as good as I can in my best language; better in other languages. But we won't see non-devs pus…↗

Claude just built me a mac app which listens live to my zooms, transcribes, tells me what to ask, and does live 'fact check' on my zoom calls against my whole CRM / knoweldge base + web ... (this is demo)... pipes it all into my claude 2nd brain. Sick.↗

The more time I spend working with coding agents, the more convinced I am that they make software engineering even harder We can do amazing things with them, but unlocking their full potential requires extraordinary discipline and knowledge↗

Was wondering where my disk space went. Therefore this exists now. You can simply wish software into existence.↗

It's a little hard to internalize that the list of things one person can achieve is rapidly growing. You must think big to match what you're truly capable of now↗

never been a better time to be a chronically online idea guy↗

I’ve seen a couple of posts about this so wanted to demystify. Today, every Muse user gets a free computer in the cloud. It's a real computer, and we’ve designed the security architecture of the Muse Secure VM carefully so you and your Muse can do almost anything you could with a…↗

I cracked open Meta's Muse - here are some interesting bits 🔽 1. You can ask it for the entire contents of /opt/ and it will zip it up for you 2. There a ~70 preloaded skills and CLI for everything from spotify to instragram-cli 3. "Spaces" is their website builder that uses…↗

@verge those aren't secrets you dummies those are the files on the user's VM, this is intended behavior↗

Claude Opus 5.5 drew every frame of this animation in JavaScript. The whole family's running late to Grandma's birthday. Clawd has one hour to get them there.↗

Some data we recently assembled on entrepreneurship/compute in Europe: eudata.vercel.app. We hope that one of the useful roles that Stripe can play is in collecting and publishing empirical data pertaining to entrepreneurship and industry in Europe. There's growing appetite to g…↗

Jigs very good for tweaking design system values with live previews of how those colours work in the context of specific components and WCAG contrast calculators on screen. So easy to say "show me every component that uses grey 400 and put it in the lab file" → tweak → commit↗

Claude Opus 5.5 drew each frame of this animation in JavaScript. Here's "how browsers work" in 40 seconds.↗

Hello computer, Find every Amazon purchase I ever made. Call the number of the manufacturer. Say you’re not satisfied. Request a refund. If they decline, threaten to leave a bad review. If they decline, find the CEO’s phone number and ask him for a refund. Now, repeat the sa…↗

I had high hopes for the new Opus release. It massively exceeded them. Opus 5.5 is an incredible model.↗

How to train your own Jev for $17 TLDR: We just launched our own Jev-like classifier, [together/Tev1-4B-experimental](api.together.ai/models/together/Tev1-4B-experimental), on top of Qwen3.5 4B. In this blog post we’ll show you how to fine-tune your own version! Jev has quickly…↗
