CVPR 2026 lead-author paper + US patent filing. Persistent, editable 4D world models at 60 fps on iPhone.
Portals is a deployed system for persistent, editable 4D spatial world models that run on the devices people already carry. It bridges 4D world-model research and lasting spatial experiences on phones, smart glasses and AR headsets — the shift from stateless scenes to stateful worlds that persist, compound and stay editable across sessions, devices and users.
Lead author on the paper accepted to the IEEE/CVF CVPR 2026 Workshop on 4D World Models: Bridging Generation and Reconstruction, with a companion U.S. provisional patent application.
