World Labs Marble (Oct 2026): persistent 3D worlds from text, images, video or a 3D blockout - models, credit costs, plan rights and export paths

Primary docs. Marble generates persistent 3D worlds (Gaussian splats, optional meshes) from a text prompt, single image, multiple images, 360 panorama, video, or a coarse 3D layout built in "Chisel" (draw walls, doorways, place a panorama camera, or upload GLB/FBX geometry, then prompt). Studio tools: Compose (join several worlds into larger environments), Record (camera flythroughs exported as video), pano edit, Expand (fix low-fidelity regions/grow worlds), variations. Models (R1): Marble 1.1 (recommended, 1,500 credits per world), Marble 1.1 Plus (largest worlds; 1,500 base + 0-1,500 variable), Marble 1.0 legacy (1,500), Marble 1.0 Draft (150 credits, fast tests) - 1.1/1.1 Plus added 2026-04-02 (R2). Credit examples (R3): single-image world = 1,500 + 80 input credits; edits 150 per pano edit; expand 2,000. Plans: Free (text/single image/pano, up to 4 worlds), Standard (multi-image, video and 3D-layout inputs, editing, export; ~12 worlds), Pro (expand, enhanced video output, high-quality textured mesh export, COMMERCIAL RIGHTS to generated worlds; ~25 worlds), Max (~75 worlds), Enterprise. Marble subscriptions and World API credits are separate accounts and not interchangeable. Exports: SPZ splats (OpenGL coordinates since Dec 2025, real-world scale since Jan 2026) to Unreal, Unity, Blender, Houdini and web frameworks (Spark); meshes vertex-coloured or textured; VR links; characters must be added in external tools. Fit: a commercially licensable (Pro) alternative to HY-World 2.0 (territory-restricted, C3-B399-01) for persistent sets; same splat limits apply (no relighting, C3-B407-01) - plan lighting at generation time. Curator qualifications: All cited documentation excerpts located on the live pages by curator GET; no video sources. Dollar prices not captured. Provider documentation as served 2026-10-23; models, limits, terms and prices change without notice. Limitations: Dollar prices on marble.worldlabs.ai/pricing not captured; plan contents may change. Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
