This AI tool generates fully explorable 3D worlds
World Labs, co-founded by AI legend Fei-Fei Li, just launched Marble—a tool that lets you whip up persistent, editable 3D worlds from simple text prompts or images.
Unlike most AI models, Marble's worlds stay consistent and let you explore way beyond the original view.
You can export your creations for web or VR
Marble can generate large, detailed environments with clean geometry—so you can peek behind objects or wander wherever you like.
You can export these worlds for web or VR using their open-source Spark renderer.
Plus, the Chisel editor lets you sketch out spaces and have AI fill in the details, keeping structure and style separate.
Pricing and who it's for
There's a free plan (4 generations), then paid options: Standard ($20/month), Pro ($35/month with commercial rights), and Max ($95/month with all features).
It's designed for creators—think gaming, VFX, VR—who want more creative control over their 3D spaces.
How it compares to other tools
Marble stands out from tools like Google's Genie or demos from Decart and Odyssey because you can actually download and edit your worlds using advanced AI-native tools.
For now, it looks like one of the most powerful commercial world models out there.
