"AI godmother" Fei-Fei Li releases first commercial world model.

The AI godmother and Stanford University professor Fei-Fei Li's startup company WorldLabs officially launched its first product Marble on November 13th. Supported by a multimodal world model, the official release states that it is the "foundation for building the future of spatial intelligence." This model can create high-fidelity, long-lasting 3D worlds based on a single image, a video clip, or a text prompt. Just two months ago, the team shared a preview version of Marble, and now that it has been officially opened to the public, the functionality has been expanded to support large-scale multimodal inputs. They have also launched a creative center called MarbleLabs and offer both free value-added services and paid subscriptions. In terms of pricing, Marble offers four subscription plans: the free version supports 4 generations, with only text and image inputs; the standard version is $20 per month, supporting multiple images, video inputs, and advanced editing; the most expensive flagship version costs $95 per month, including 75 generations and unlocking all features.
