🧵 Evaluating robot policies in the real world is slow, expensive, and hard to scale. During my internship at @SceniXai this summer, we had many discussions around the two key questions: how accurate must a simulator be for evaluation to be meaningful, and how do we get there?

To scale robot intelligence, we must scale the worlds in which robots learn 🌎🤖

When SceniX joined World Labs, we said spatial intelligence was never only about perceiving and generating virtual and physical worlds, but also interacting with them. Today, we’re sharing early results from that vision: building worlds that train robots. 🌎🤖↓

You only realize time flies too fast when close friend sets off on a new journey. Forever friend, labmate, and (former) roommate, Yixuan, best wishes!

Finally PhDone after two years in Columbia! Huge thanks to my amazing advisor @YunzhuLiYZ and it would be definitely impossible without his support and guidance! I sincerely appreciate my committee, Richard Zemel, @Zhou_Yu_AI, @dineshjayaraman, and @Majumdar_Ani, my dear

We’re showing that the spatial intelligence we’re building at World Labs has a clear mission: to move beyond the digital realm and into the physical world. With SceniX and our expertise in simulation and robotics, the future looks incredibly bright!

The world is not just made of words, and spatial intelligence was never just about perceiving and generating worlds. It's about interacting with them. Today, SceniX is joining World Labs. 🌎🤖👇
