腾讯开源混元世界模型1.1，视频秒变3D世界，单卡推理仅需1秒

Core Viewpoint - Tencent has released and open-sourced the Hunyuan World Model 1.1, a unified end-to-end 3D reconstruction model that supports generating 3D worlds from multiple views or videos with high precision and efficiency [1][3][16]. Group 1: Model Features - Hunyuan World Model 1.1 is the industry's first unified feedforward 3D reconstruction model, capable of handling various input modalities and producing multiple outputs simultaneously, achieving state-of-the-art (SOTA) performance [4][18][21]. - The model supports flexible input handling, allowing the integration of camera poses, intrinsic parameters, and depth maps to enhance reconstruction quality [18][20]. - It features a single-card deployment with one-second inference time, significantly faster than traditional methods that may take minutes or hours [22][24]. Group 2: Performance Comparison - In comparisons with Meta's MapAnything and AnySplat models, Hunyuan World Model 1.1 demonstrated superior surface smoothness and scene regularity in 3D point cloud reconstruction tasks [11][12][14]. - The model excels in both geometric accuracy and detail restoration, providing more stable and realistic scene reconstructions compared to its competitors [14][15]. Group 3: User Accessibility - The model is fully open-sourced, allowing developers to clone it from GitHub and deploy it locally, while ordinary users can access it online to generate 3D scenes from uploaded images or videos [34][37]. - The technology aims to democratize 3D reconstruction, making it accessible for anyone to create professional-level 3D scenes in seconds [37].
