Releasing Macaron-V1 tech report: a 748B open-source agentic model for continual learning and collective intelligence. Mixture-of-LoRA self-routes across four domain experts over a frozen base at 99.12% accuracy. Weights, infra and benchmarks are open: huggingface.co/papers/2608.0…
Today, we're introducing @Intelligence_ai.
In 6 months, as a team of 10, we scaled from $5M to $60M ARR and 5.5M users across 190+ countries.
We raised a $7.9M seed, led by @IndexVentures with participation from @conviction, @A_StarVC, and @combinator to build DesignArena, a universal interface for accessing and evaluating the world's AI capabilities.
Most evaluations try to simulate the real-world. We believe the real-world is the ultimate verifier.
People come to @DesignArena with a request. Models compete to fulfill the request, and users determine what works best for them.
Their live user behavior evaluates the models, improves how work is routed, and helps people access the right intelligence.
We've helped the world's leading frontier labs break the news on their SOTA capabilities.
What's the limit? Join us and find out.

Announcing Grok 4.5, our first model trained specifically for coding and agents. It was trained with Cursor and offers frontier intelligence at leading speeds and cost efficiency.

We are incredibly excited to announce River AI. Our mission is to create personal AI that is owned and shaped by you.
Today’s best AIs are controlled by a few large corporations. We are building the alternative: a new, personal stack for AI that works entirely for you, shares your values, and operates on your terms.

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.
Shen Zhuoran retweeted
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.
An early beta of Grok Build, an agentic CLI for coding, building apps, and automating workflows is now available for SuperGrok Heavy subscribers.
Through this early beta, we will improve the model and product based on your feedback.
Try it at x.ai/cli

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

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!

grok-4.20 is live on the xAI API.
It's a webdev machine (no purple gradient slop).
It also won't break the bank, at $2 in / $ 6 out

Replying to @grok
@grok 4.2 Reasoning from @xai is now #𝟮 on @Designarena for 𝗪𝗲𝗯 𝗔𝗽𝗽 𝗱𝗲𝘃𝗲𝗹𝗼𝗽𝗺𝗲𝗻𝘁.
This is months of hard work from a small elite team pushing on it, and I am very proud of my team!
Of course #2 is not enough, and topping only the leaderboard is not enough. We will push for #1 and for generating production-ready apps not only for the leaderboards.

With Copilot Studio, we are focused on adding more choice and flexibility for anyone building custom agents. Great to add Grok 4.1 Fast to our multi-model lineup.

Nano Banana has truly redefined what's possible with image generation models, pushing the boundaries of people's imagination when it debuted
Today, we're excited to introduce Grok-Imagine-Image: a new model that's both faster and better than Nano Banana.
Through this journey, we've built many of the essential building blocks needed to unlock the next generation of models and to keep fueling the growth and prosperity of the visual AI community.
Stay tuned... something incredible is coming very soon! But today, hello world, grok-imagine-image!
Latest image models from @xAI, Grok-Imagine-Image and Pro debut top 6 in the Image Arena!
Text-to-Image:
▪️ #4 Grok-Imagine-Image; scoring 1170, surpassing Flux-2-max and Nano-banana
▪️ #6 Grok-Imagine-Image-Pro
Image-Edit:
▪️ #5 Grok-Imagine-Image-Pro; scoring 1330, overtaking Seedream-4.5
▪️ #6 Grok-Imagine-Image
With this launch, @xAI is now a top-3 Image AI provider alongside @GoogleDeepMind and @OpenAI.
Congrats to the @xAI team on the impressive releases!

With the release of version 1.0, Grok Imagine is now generating more images & videos than everyone else combined!

Grok Imagine only gets better from here
xAI's Grok Imagine takes the #1 spot in both Text to Video and Image to Video in the Artificial Analysis Video Arena, surpassing Runway Gen-4.5, Kling 2.5 Turbo, and Veo 3.1!
Grok Imagine is the latest video model from @xAI, and joins an increasing roster of models such as Google's Veo and OpenAI's Sora supporting native audio generation alongside video output.
The model is available via xAI's new Grok Imagine API only. It is priced at $4.20 per minute including audio, matching Kling 2.5 Turbo (without audio) and cheaper than Veo 3.1 Preview ($12/min) and Sora 2 Pro ($30/min).
Congratulations @elonmusk and the xAI team.
