Twitter’s algorithm is optimized for addiction, not for us. We deserve better. We’re releasing Bouncer today so you can take back control of your feed. Describe what you don't want, and Bouncer removes it. It’s free, doesn’t collect your data, and will be open source soon.

It’s currently 2am, and I’m reading in a bookstore that’s also a bar. Why aren’t all cities like this?

I'm excited to share our $200M Series B at a $1B+ valuation to develop AI systems that reason! We believe reasoning is the main blocker to effective AI agents. We train large models tailor-made for reasoning on our ~10K GPU cluster. On top, we prototype agents we use every day.

Teaching is perhaps 100x harder than we expect. The common misconception is that it’s about sharing your knowledge; it’s not. Rather, it’s about understanding what’s in the student’s mind, modeling that in your mind, building a bridge from the student’s mental state to yours.

Sculptor: the missing UI for Claude Code 🎨 Imagine running 5 Claudes in parallel, safely in containers, while you stay in flow. Then bring their work straight into your IDE to test/edit together. This is how one developer ships like a team. Try it with Sonnet 4.5!

I like people who try very hard. I find it odd that even as an adult, being "cool" seems to involve not caring too much and not appearing to try too hard, yet all the interesting things in human history have been done by people who cared a lot and tried unusually hard.

Today, AI systems can create stunning art & beat humans at chess & Go. But they can't do things a 3-year-old can do. Why? We're launching @genintelligent & open sourcing our research environment, Avalon, so as a community we can answer these questions: generallyintelligent.com/launch/

In 2020, @michael_nielsen & I began a 2-month project to write: "how would we fund science?" 2 years & 40,000 words later, it's become: "how can the culture & institutions of science actually change, and ultimately become self-improving?" Our answer: scienceplusplus.org/metascience/in…

In the past year, I’ve talked to many bright, curious, ambitious people who believed they couldn’t do research. That was me, not long ago. Here I share my improved understanding in hopes of offering a more empowering model of what research entails: kanjun.me/writing/resear…

To guarantee an interesting conversation with any person, ask: “What is something you feel like you’ve thought about more deeply than most other people?”

Perhaps the job of a teacher should not be to convey information, but rather to kindle curiosity.

Today, AI can generate tons of code—but how do we know if it's good? That's why we built Sculptor: the first coding agent environment. Sculptor helps you catch issues, write tests, and improve your code—all while you work in your favorite editor.

Reflections on Miami so far👇 1/ This city makes me feel shameless. I can wear anything, dance on the street, wear nothing, shout at the top of my lungs, and nobody will blink an eye. This is liberating!
