Today we're launching Claude for Teachers -- premium @claudeai and Cowork, free for every US teacher. Teachers have been experimenting with AI for a while. But they told us they wanted something curriculum-aligned, evidence-based, and able to work in the background while they focus on their students. Four things that I think make this special:


Personal update: I'm taking a leave of absence from YC to join Anthropic. I'll be working with @NotTomBrown on the compute team. Powerful AI has the potential to improve the life of every human on earth and, as we enter the early stages of recursive self-improvement, availability of compute becomes one of the most important issues to solve. I'm excited to get started 🚀





The inbound from new robotics data vendors has been nonstop since last November. Half the companies that messaged us back then have since pivoted to something else. Collecting high quality robotics data is just brutally hard, and the market keeps proving it The data ops team @sundayrobotics is genuinely world-class, led by the one and only @perryzjia. Come join us, we’re hiring :)


Lucy Guo(卢茜·郭),美籍华人的耻辱。2018年被自己联合创立的Scale AI开除,2025年却凭借15亿美元身家挤掉霉霉,摇身一变成为最年轻白手起家女富豪。转头她又去搞擦边色情平台Passes,充斥着淫秽和未成年人涉黄争议。作为一个迈阿密派对浪女,把硅谷精英和成人产业玩弄于股掌。在硅谷,作恶才能成功?

This is the slide deck from our seed round in September of 2023, right after @adarsh_exe, @suryamidha, and I dropped out. It was clear that organizing human intelligence was the core bottleneck to AI progress. Most investors who passed on the round claim that it was before we "pivoted" into the AI data market. It's funny how selective memory works.

@JayaGup10 Chinese labs are now part of this as well



Ive been telling friends who want to do start ups. Easiest way to get revenue and raise a few M: 1. Find something the models are bad at that people care about 2. Make a bench for it 3. Shout on X that some lab is better than other lab. 4. Sell data for the bench to other lab
