Marble 1.1 / 1.1 Plus
Released Apr 7, 2026
World Labs' generally available multimodal world model that turns text, images, multi-view images, panoramas or video into navigable, editable 3D worlds (Gaussian splats and meshes), with a Plus variant for larger worlds.

Strengths & weaknesses
Strengths
- Exports Gaussian splats (SPZ/PLY), collider and high-quality GLB meshes, and panoramas
- Broad input set: text, single image, multi-image with azimuths, 360° panoramas, video
- In-app editing, world expansion, composition and Chisel 3D layout sculpting
- Public World API alongside a consumer app with a free tier
Weaknesses
- Generation takes about 5 minutes per world
- Static scenes, not a real-time simulation
Date conflict: Marble release notes list 1.1 and 1.1 Plus under 2026-04-02; World Labs' X post saying 'rolling out ... today' is timestamped 2026-04-07 (used). Marble itself went GA 2025-11-12; World API launched 2026-01-21. Marble 1.0 / 1.0 Draft remain selectable (marble-1.0, marble-1.0-draft) but not added separately. interactive true = navigation/editing of generated static scene. Max plan price not on the docs page (a stale-indexed pricing page shows $95/mo; unverified). World Labs agreed to be acquired by AMD (announced 2026-09-28). RTFM (real-time frame model research preview, 2025-10-16) not added.
