Worlds in Action Hack San Francisco

is the first spatial and physical AI hackathon built entirely around world models, not as theory, but as things you can explore, break, and ship with.

​World models are the next ChatGPT moment.

​LLMs learned language. World models learn physics. They predict how objects move, collide, and behave - not from text, but from real-world spatial understanding. That's why they're transforming robotics, simulation, game development, and XR at the same time.

​The pipelines are here. Most people just haven't used them yet.

​This hack changes that.

• ​​ provides Physical AI Tuning Platform, VLM and VLA models, along with the fine-tuning workflow, so teams can focus on learning and iteration instead of setup.
• ​​ global academy teaching XR, AI and organizing SensAI Hacks across the world.
• ​ providing the Hack with awesome awards, exciting Devkits and headsets!

Generate a 3D environment from a prompt using World Labs Marble. Import it into Unity, Unreal, or WebXR. Train a robot in that environment using NVIDIA Isaac. Deploy it to real hardware on-site. Ship an immersive experience to a PICO headset.

• ​40+ robots on-site
• ​World Labs Marble, Genie, Ling Bot World
• ​NVIDIA Isaac sim-to-real pipelines
• ​VLM/VLA fine-tuning workflows
• ​PICO devkits + SDK support
• ​Unity/Unreal/WebXR integration pipelines
• ​WebSpatial cross-platform deployment
• ​Mentors and technical support throughout

​and a fantastic team of advisors, mentors and judges being on-site to help you out:

​To make sure you'll be equipped with all skills you need,!

​🎯 For XR/Game Developers • Physical AI Engineers • Creative Builders • Autonomous Systems Researchers • Anyone exploring where world models are heading

​Expect: Early tech, weird ideas, fast iteration, builders shaping playable reality.
