- 原文: astra is a powerful model and we are working to make it generally available. we do not think it is a good strategy to keep powerful models to a chosen few. given its cyber capabilities, we need a little big longer to do do this safely. but hopefully not too long!

- 原文: After evaluating one of our upcoming models, Astra, we're treating it as our first "critical" model for cybersecurity under our Preparedness Framework. This is a scenario we've planned for, and we're putting additional controls in place to ensure Astra's further development happens safely and securely. We're working hard to make Astra broadly available, and get its advanced cyber capabilities into the hands of defenders.

- 原文: I'm impressed with the new Grok Image model and editing features! Screenshotted a few items from the Gap website and generated a quick photoshoot. The workflow tools are cool - items/people are segmented to edit, you can change the aspect ratio, and incorporate new references.

- 原文: Criticism is welcomed and encouraged at Bridgewater, but there is never a good reason to bad-mouth people behind their backs. It is counterproductive and shows a serious lack of integrity, it doesn't yield any beneficial change, and it subverts both the person being badmouthed and the environment as a whole. Next to being dishonest, it is the worst thing you can do in our community.

- 原文: Building a DIY squat rack used to make sense, but now it’s almost always cheaper to buy new. This rack costs $400+ in materials alone, not to mention a full weekend of time plus tools needed. I’ve bought racks that are stout, modular, and more versatile for under $100. If you like the hobby, build away, but plan on spending more than you expect.

We want to create an awesome environment with a great culture of technical excellence, teamwork, respect, and ambition. We’ll also start building our infrastructure and AI models and systems to tackle our first domain: automating large-scale experimentation for ML research and engineering. In doing so, we’re going to be our own first customers. The rapid feedback from doing that is the way to build something amazing. Oh, we’re hiring! See"
