Spark 2.0 is an open-source 3D Gaussian Splatting renderer built on THREE.js and WebGL2. Featuring a new streamable Level-of-Detail (LoD) system and virtual memory, it streams massive 100M+ splat worlds to any browser, mobile, or VR device in real-time.

World Labs' latest 3D generation update introduces two models. Version 1.1 improves lighting, contrast, and reduces artifacts. The 1.1-Plus model automatically expands 3D space coverage to generate significantly larger, more complex environments.

A public API for generating explorable 3D worlds from text, images, and video — bringing Marble's world modeling capabilities into your applications.

Marble is the first product from World Labs and is powered by our multimodal world model, which lets anyone create high-fidelity, persistent 3D worlds from just a single image, video, text prompt, or 3D layout.
