World Labs releases Marble 1.1, with the new Plus version supporting automatic expansion of 3D world space for the first time

According to 1M AI News monitoring, AI spatial intelligence company World Labs recently updated its 3D world generation model Marble, adding two new models: Marble 1.1 and Marble 1.1 Plus. Marble 1.1 is now the new default model, improving lighting and contrast while reducing visual artifacts. The generation cost is fixed at 1,500 points per run, the same as the previous-generation Marble 1.0.

Marble 1.1 Plus is the more noteworthy update. Previously, the 3D world spatial coverage of all Marble models was fixed. The Plus version is the first to introduce automatic spatial expansion: when the input prompt involves outdoor or large indoor scenes, the model automatically increases its 3D spatial coverage range, without requiring users to manually extend the boundaries. Pricing has also changed to a floating-rate structure: a base fee of 1,500 points plus a variable generation fee of up to 1,500 points. The exact amount depends on the spatial coverage range the model expands. This is Marble’s first use of variable pricing.

Both models can be called via the World API and support four input types: text, a single image, multi-angle images, and video. A single generation takes about 5 minutes. The original Marble 1.0 and 1.0 Draft (a fast draft version, 150 points per run) remain available.

World Labs was co-founded by Fei-Fei Li, a professor of computer science at Stanford University. It focuses on spatial intelligence. This year, in February, it completed a $1 billion funding round, with investors including AMD, Nvidia, and Autodesk.
