Project Lyra is NVIDIA's open series of generative 3D world models, including Lyra 1.0 for feed-forward 3D/4D scene generation from a single image or video and Lyra 2.0 for explorable, long-horizon 3D-consistent world generation. It provides official model weights, training code, and a GUI.

Use cases

• generate 3D scenes from a single image
• create explorable 3D worlds from video
• reconstruct 3D scenes with gaussian splatting
• train a generative 3D world model
• generate 4D scenes from video
• run a 3D world model locally with a GUI

When to choose

• you need state-of-the-art generative 3D scene or world generation
• you want to build interactive, explorable 3D environments from images or video
• you are researching video-diffusion-based 3D reconstruction and have GPU resources

When to avoid

• you need lightweight 3D modeling without heavy GPU compute
• you need a production game engine rather than a research model
• you require permissive licensing of the model weights, not just the Apache-2.0 code
