I left xAI earlier this week. It was a difficult decision. The past two years have been an intense, fun, and deeply rewarding journey, and I accomplished things I could not have imagined two years ago. Thank you @elonmusk for the opportunity and for everything I learned at xAI. Thank you @Guodzh for the trust you placed in me and for all the days and late nights we worked through together. And thank you to the entire Omni / Imagine team: thank you for your trust, and for growing together with me. It has been an honor, and I am incredibly proud of what we achieved together. I feel fortunate to have had the chance to work with all of you. At xAI, everything feels possible. I had the chance to work with and learn from some of the most exceptional people I have ever met. I was able to explore across domains: from pretraining to post-training, from language models to multimodal, from perception to generation. Joining xAI was one of the best decisions I have ever made. @grok imagine is special to me. Building video generation models, where I started with almost zero prior knowledge, from 0 to No.1, as an IC and as a lead, alongside an extraordinary team, and shipping it as a great product used by millions, all within 6 months, at age 28: I feel proud. But now it’s time for me to move on. I’m burnt out, and I know my happiness is no longer maximized in my current state. It is sad to say goodbye, but it is just the right time for a change. Best wishes to the Imagine team, you are absolutely the best, and you deserve the best. I will cherish all our memories for the rest of my life. For now, I’m taking a break and giving myself time to figure out what comes next. Posted from Hawaii.

I left xAI today. It was truly rewarding to contribute to grok imagine video series: 0.9 as our first release, then 1.0 that recently topped across competitive leaderboards and user feedback. I see a mix of humble craftsmanship and ambitious vision throughout the team. They taught me about what I want and how I want to proceed in my career. Thank you to everyone who made this journey unique and memorable.

I resigned from xAI today. This company - and the family we became - will stay with me forever. I will deeply miss the people, the warrooms, and all those battles we have fought together. It's time for my next chapter. It is an era with full possibilities: a small team armed with AIs can move mountains and redefine what's possible. Thank you to the entire xAI family. Onward. 🚀 And to Elon @elonmusk - thank you for believing in the mission and for the ride of a lifetime.

Imagine-Image is at the Pareto front: Better, Faster & Cost efficient🚀 And we will be even better in weeks🫡🫡 (Kudos to the amazing xAI team and all my lords🤣)
Arena.ai@arena

The new @xAI Grok-Imagine-Image model is a Pareto-optimal model in Image Arena: The Pareto frontier tells us which model has the highest Arena score at each price point. @xAi’s latest models have improved the frontier, giving optimal performance in the mid-price tier. For a wide range of prices between 2c and 8c per image, @elonmusk’s @xAI has the leading model, delivering the maximum performance. Top models on the Pareto frontier for Image Arena (Single Image Edit): - @OpenAI: GPT-Image-1.5-high-fidelity - @xAI: Grok Imagine Image Pro - @xAI: Grok Imagine Image - @bfl_ml: Flux 2 Klein 9B - @bfl_ml: Flux-2-Dev - @reve : V1.1 Fast See thread for how the frontier changes for Text-to-Image 🧵

BREAKING: @xAI’s Grok-Imagine-Video now #1 in Video Arena! For the first time, Grok-Imagine-Video-720p takes the top spot on the Image-to-Video leaderboard, overtaking Google’s Veo 3.1 while being 5x cheaper. Its 480p version released a few days ago ranks #4. Huge congrats to @xAI team and @elonmusk on this incredible milestone!

This is the second #1 I achieved at @xAI! (the first one was Grok 3 with my best post-training friends ;). After shipping Grok 4, I jumped into something completely new to me — video generation with @imhaotian and @zeliu_. In just 6 months, the team built everything from 0 to 1 to #1. How did we make this happen? For me, it's mostly about the best intuition and execution — and having the best friends to work with. My best take on both achievements is that we should respect users and focus on things that can scale. This is just the start. Stay tuned for what we’ll achieve next.

What a remarkable journey to work with such a talented team and brilliantly creative minds, and witness how imagination can be set free in the most astonishing ways!
Minxuan Xie@MichelleShieh

It was fun when the team hung out with creators to improve our video editing model on each real use cases! It's the best model, but more is coming! Join our creator chat with @YknZhu, @XiangLi5217365 , @mingdaz_xai, @hangg70, @never1andd, @keyang_xx, @jamesxu, @nonieengel

Very excited to share our first public release after I joined @robbyant_brain! We present Lingbot-Depth 👀 — a state-of-the-art depth foundation model trained with RGB-D MAE on millions of real & simulated RGBD pairs. 🔹 Camera depths as natural masks for RGB-D MAE modeling 🔹 Large-scale real + sim RGBD data curation pipeline What surprised us most: ✨ Significant improvement on transparent, reflective surfaces, and thin structures — traditionally the hardest cases for depth models. 👇These are some of hard causal-capture images we tested on. The results are pretty good! #DepthEstimation #FoundationModels #EmbodiedAI #3DVision #Robotics #RobbyAnt
