According to @drfeifei referencing World Labs, the company rolled out two model updates—Marble 1.1 and Marble 1.1-Plus—aimed at higher-fidelity 3D scene synthesis and larger-scale world generation. As reported by World Labs on X, Marble 1.1 improves lighting and contrast while cutting visual artifacts, and Marble 1.1-Plus is engineered to create larger, more complex environments for production-scale pipelines. According to World Labs, these enhancements target scalability and visual quality, enabling studios and game developers to generate expansive levels and virtual environments faster with fewer post-processing passes. As noted by Fei-Fei Li’s post citing World Labs, the updates signal growing momentum in AI-native world building, with immediate opportunities in game prototyping, virtual production, and simulation workflows that require consistent lighting and efficient asset iteration.
