InSpatio · Explorable World Model

InSpatio-World 1.5

Follows InSpatio-World, covered here in week 31 as a 1.3B model that turns a reference video into an explorable 4D world. Version 1.5, with weights out on 24 September, accepts a single image, a set of four images, a panorama or a video, allows wider camera moves while staying consistent, and adds next-view prediction for dynamic video scenes. The checkpoint is still 1.3B parameters on the Wan2.1-T2V-1.3B architecture, with Depth Anything 3 for depth and camera estimation; you supply a target camera trajectory and video input is resized to 832x480. Code Apache-2.0, weights on Hugging Face and ModelScope, demo at world.inspatio.com. No speed or benchmark numbers for 1.5.
