This also shows up in the representations learned by the model. We plot the model’s representations of human and robot images. As pre-training is scaled up, the representation of humans and robots become more aligned: to a scaled-up model, human videos "look" like robot demos.

The concept of creating an exact digital replica of the physical world has always fascinated me: environments that look and behave exactly like our everyday reality, precisely captured in the digital domain. This is the essence of 𝐖𝐨𝐫𝐥𝐝 𝐌𝐨𝐝𝐞𝐥𝐬, simulated realities indistinguishable from our own. Generating these models is the core mission behind what we are building at SpAItial AI. True World Models must capture both photorealistic appearance and underlying physics, spatially-consistent across the environment. For static scenes, current models already deliver impressive results, unlocking downstream applications from gaming to 3D design. However, the true frontier lies in modeling dynamics, which will enable the training of AI agents whose learned behaviors can bridge the sim-to-real gap, thus unlocking countless real-world applications.

🚨 REP. BRANDON GILL (R-TX) JUST SAID IT PERFECTLY: "The choice to vote for a Democrat Party committed to opening our borders to the world is a choice to commit civilizational suicide." "Everything that directly impacts your life— affordability, safety, cultural stability— all of it is downstream from immigration." 💯💯

Having a few hours this afternoon after #CVPR2026? Consider visiting Red Rocks 20 minutes outside of Denver! For some inspiration, here's a world processed by SpAItial AI Echo-2 HQ model from a single phone image! Link to the world in🧵

I only knew Tina 6 months from start to finish but the book is a story of true love and how one dog or person can try to change the world. You can pre-order here

Evaluating policies on a real robot can be painful. Can we use a world model to get a rough estimate of how good a policy is? Checkout "Evaluating Robot Policies in a World Model". Paper: Demo: Code:

There is hope that this moment can open a path towards a free Iran. That is what the Iranian people deserve : freedom, dignity, and the right to decide their own future. But allow me to make one important point. Seeing the world as it is in no way diminishes our determination to fight for the world we want.

🚀🌍🚀 Echo-2 is live! It generates high-quality physically grounded 3D scenes instead of just pixels. Check out the open demo to create and explore worlds in real-time! I gave it a picture from my Himalayas trek—it handles the massive scale range really well! 🏔️🌍

Population dynamics can provide insights into domains ranging from health to environmental science. Here we introduce a geospatial foundation model (plus embeddings and code recipes) that could be employed for a variety of downstream tasks. →

We just pushed a new version of esoterica to github. This is the culmination of around 2 years of work. Massive improvements across the board most notably a modern DX12 renderer. If you want to build your own engine, it's a great starting point!

how small can you make a world model? we built mira mini, the first reproduction of mira: •⁠ ⁠reproduced in a week from scratch •⁠ ⁠four players, one shared rocket league match, in the browser •⁠ ⁠distilled to 364m params, weights, code, full report: all open. play it here ↓

When we began testing #GeminiOmni I wanted to see the accuracy of the edits. So I made a tool directly in Google Flow. DIFF TOOL allows you to compare images/videos in realtime or export videos in sync. Try it out or remix it to make it your own.

It was all so we could build homes with robots. All of our work in floorplan AI,and generative CAD modeling, we did all of that, just so that we could build homes with robots. Early on we talked to a robotics engineer from Katerra. It took them $750k to switch from one house to another house. It takes us 25 minutes, and that's if we had a big lunch. P.S. The soundtrack is hardcore punk, lyrics written by me, but everything else is udio.
