Why We're Building Muse Most people never say what they want. It’s not because we don’t want. We want fiercely and constantly. It happens in the moments before falling asleep or while daydreaming on the car ride home. We want to spend more time with our families, overcome socia…↗

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 stun…↗

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…↗

Was wondering where my disk space went. Therefore this exists now. You can simply wish software into existence. https://t.co/hd1uCGo9ck↗

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 eff…↗

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 imag…↗

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↗

Every time you let Opus 5.5 run a long task on its own, have it vibe-code a quick 𝗛𝗧𝗠𝗟 𝗱𝗮𝘀𝗵𝗯𝗼𝗮𝗿𝗱 like this first. Then give it 𝗮 𝘀𝘂𝗯𝗮𝗴𝗲𝗻𝘁 𝘁𝗵𝗮𝘁 𝗼𝗻𝗹𝘆 𝗯𝘂𝗶𝗹𝗱𝘀 𝗱𝗮𝘀𝗵𝗯𝗼𝗮𝗿𝗱𝘀: → Name it dashboard-builder, set its effort to medium, and preloa…↗

one Opus 5.5 prompt, and now I run around a virtual office managing agents to work on github issues and merge conflicts https://t.co/7j6Qs1G8eL↗

Excited to introduce @Cosign: the curated professional network for the startup community: https://t.co/zhjIYSCigC 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 …↗

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 no…↗

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!).↗

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 s…↗

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↗

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 pu…↗

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: https://t.co/yZnatuYSKK↗

Muse will be the top installed app for a while thanks to Meta’s distribution might.. But they are starting to have a retention issue: most people still don’t know what to do with a personal agent, so they lose interest after a while. I bet Muse will get much more proactive ra…↗

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?↗
