A world model lets users generate, explore, and interact with fully 3‑D environments from simple prompts
- The model takes textual or image prompts and synthesizes a navigable 3‑D scene with geometry, textures, and physics.
- Users can walk through the scene, pick up objects, or change the environment, enabling both creative and analytical tasks.
- Fei‑Fei Li emphasizes that this goes beyond video generation; the output is a structured world that can be queried and manipulated.
- The capability opens doors for designers, game developers, and researchers who need rapid prototyping of immersive spaces.
- This insight captures the core functional definition of world models as interactive, generative spatial engines.
