Excited to see people try Grok Build for web dev. Our team has put a lot of effort into improving its aesthetics, functionality, and more exciting features to be expected with recursive self-improvement loop. It’s still early beta, and feedback is very welcome. Please try it out and let us know where we can improve.

@boyuan__zheng @xai Finish our push for the best web dev model in the world 🔥🔥🔥!

@CMS_Flash @xai Will miss you, bro🥲 Really enjoy working with you on web dev and brainstorming recursive self-improvement. All the best!

I left @xai last week. It was quite a journey. I learned a lot technically and made some lifelong friends. I was fortunate to have spent almost all of my xAI tenure on a singular, long-term project on optimizing Grok's ability to one-shot complex, complete, and polished web apps. I am proud of this team. We contributed one of xAI's most successful alignment recipes, which has been replicated to other teams. We scaled another innovative recipe to incredible scales, for which Grok 4.3 gave a tip-of-an-iceberg preview. I am excited to see its full impact reveal on future releases. Looking forward, we are now at a critical point in the history of AI. Coding is on track to become a solved problem and AI is on the brink of its first total disruption of a major industry. Models show the first signs of substantial participation in their own development. The singularity might be on the horizon. Today might be analogous to the eves of AlexNet and GPT-3, or perhaps more profound. I am excited for what is to come.

@JaySym_Ai How to get access to Cosmos?

Thanks, Cosmos. I no longer need to leave my macbook open all day long

@zhmeishi @xai It was a memorable journey pushing on web dev together with you!

@CMS_Flash @xai Wish u all the best, Zhuoran!

@OpsoFacto @xai No.

@CMS_Flash @xai Are you at spacexai

@HoneybadgerFan4 @xai Sure, lemme know when you want to play!

@CMS_Flash @xai Interested in onboarding the handyman to the AI Age? Also interested in a 2v2 - I can bring a decent 6 pool rush to the table

We put a lot of work into making it smarter and stronger at coding, especially for a small model. Excited for what's coming next with bigger models training at Colossus 2.

@ar0cket1 Why?

@CMS_Flash imo residuals are a skill issue

1. Residual connections 2. Attention mechanism 3. Linear attention

End-to-end eval is the way to scale to the future. For general coding, it will be whole repo generation for production-scale libraries, tested by UTs. For app development, it will be one-shotting production-grade apps, like Amazon, X, or Workday, tested by agentic grading.

@Designarena @XiaomiMiMo @Xiaomi No scores yet?

MiMo-V2.5 by @XiaomiMiMo and @Xiaomi has been added to Design Arena! Built for complex agent and coding tasks, with strong visual reasoning, precise chart understanding, and deep multimodal capabilities.

Agents are pretty much just English compilers.

Incredible to see what we've been cooking this past month — and this is only the beginning. Stronger models and richer capabilities are on the way. What excites me most: what happens when the web dev model hits a singularity and unlocks Computer Use Agent self-play? Proud to be part of the team building this🚀

Good job team!~ @ahmnav @CMS_Flash @arnogau @boyuan__zheng @ebecker_xai @1kevin_h @michaelbzhu @zhmeishi

Cool work of the team is finally out in the world. This is a very early preview, and much more is to come around: - One-shotting complex web apps; - Pure vibe coding; - Self-improvement between browser use and web app development. The last point is critical and unique to web dev, because there is an intelligence gap between using a web app and building a web app that we can exploit, in theory leading to indefinite scaling of self-improvement.

Coming soon!

A full-scale US Waymo rollout would cost ~700 full-time jobs in the funeral care industry (by saving around 35 thousand young American lives per year). Will no one think of (some of) the morticians!

@skcd42 Software -> game engine -> video gen, sounds about right

every well written software looks more and more like a game engine

Stock Arena when?
