Get up to $1000 in OpenAI API credits by sharing an eval where GPT-4.5 or o3-mini doesn’t do very well. Lots of high taste testers here on this site, so I’m expecting we’ll hand out a good number of these 😉

OpenAI has defied the odds to become a truly great top-down product company. They consistently productize emerging research in useful and often viral ways. In perhaps the most competitive software category ever. With the whole world at their heels. Hats off to Sam Altman & co.

Open Source Robot Company K-Scale Labs has announced a ~$9,000 personal robot. The entire robotics open source system: hardware, software, and machine learning infrastructure, all tightly integrated and ready for your use case. I am placing an order. I will also order Optimus.

For people who don't like Claude's behavior here (and I think it's totally valid to disagree with it), I encourage you to describe your own recommended policy for agentic models should do when users ask them to help commit heinous crimes. Your options are (1) actively try to

Earlier this year, I reached conviction that we'd see true agentic software engineers within 18mo, and I didn't want to miss out on the fun. Excited to share that I've joined the @openai Codex team to work on this! We're quickly growing the team in SF - hiring FS/product and
