What is Hunyuan World Model 1.1？
Hunyuan World Model 1.1 (HunyuanWorld-Mirror) is an open-source 3D world generation model released by Tencent. It supports multiple input types such as multi-view images and videos and can output various 3D geometric prediction results including point clouds, depth maps, and camera parameters. Built with a pure feed-forward architecture, the model can be deployed on a single GPU, achieving second-level inference—processing 8–32 view inputs in just one second locally.
Its technical framework integrates multimodal prior prompting, a unified geometry prediction architecture, and a curriculum learning strategy. Through a dynamic prior injection mechanism, the model can flexibly adapt to any combination of priors. During training, it employs a curriculum learning strategy across task order, data scheduling, and resolution progression to maximize generalization. Hunyuan World Model 1.1 demonstrates outstanding performance in 3D point cloud reconstruction and end-to-end 3D Gaussian Splatting (3DGS) reconstruction, achieving exceptional geometric precision and detail restoration.
Main Features of Hunyuan World Model 1.1
-
Multimodal Input Support
Accepts multiple input types, such as multi-view images and videos, providing a rich data foundation for 3D world generation. -
Unified Multi-Task Output
Outputs point clouds, depth maps, camera parameters, surface normals, and 3D Gaussian points simultaneously, supporting diverse application needs. -
Single-GPU Deployment with Second-Level Inference
The pure feed-forward architecture enables deployment on a single GPU. When processing 8–32 view inputs, inference takes only one second locally, ensuring efficient and fast 3D world generation. -
Flexible Prior Adaptation
With a dynamic prior injection mechanism, the model can flexibly adapt to any combination of priors—or even perform 3D reconstruction without any prior input. -
Strong Generalization Ability
The curriculum learning strategy maximizes the model’s ability to generalize beyond a single image distribution, enabling it to handle diverse input data effectively. -
High-Precision 3D Reconstruction
Excels in both 3D point cloud and end-to-end 3DGS reconstruction, offering superior geometric accuracy and detail restoration—ideal for high-quality 3D content creation.
