群核科技开源两款空间大模型，想解决 Genie3 没能彻底解决的问题

Core Viewpoint - The article discusses the emergence of "world models" in AI, highlighting the release of Genie 3 by Google DeepMind and the advancements in 3D spatial models by Qunke Technology, which aim to address the challenges of spatial consistency in AI-generated environments [2][8]. Group 1: Types of World Models - There are two main types of world models: video models like Sora and Genie 3, which simulate the physical world using 2D image sequences, and large-scale 3D models that focus on reconstructing 3D scenes [4][5]. - Video models struggle with maintaining spatial consistency due to their reliance on 2D images, while 3D models face challenges in creating comprehensive spatial content from multiple angles [6][8]. Group 2: Qunke Technology's Innovations - Qunke Technology introduced the first 3D indoor scene cognition and generation model, SpatialGen, which addresses spatial consistency issues by generating a navigable 3D space that supports any viewpoint switching [8][10]. - SpatialLM 1.5, a spatial language model, allows users to generate interactive 3D scenes through natural language commands, significantly enhancing usability for non-experts [10][11]. Group 3: Technical Foundations - SpatialGen utilizes a multi-view diffusion and 3D Gaussian reconstruction technology to ensure that lighting and texture remain consistent across different viewpoints [14][15]. - The models are built on a foundation of extensive 3D spatial data, with Qunke's tools generating structured 3D data that includes physical parameters and spatial relationships [16][18]. Group 4: Market Opportunities and Challenges - The current state of spatial models is likened to early versions of GPT, indicating that while they have foundational capabilities, they are not yet universally applicable [20]. - The demand for AI-generated short films presents a significant opportunity, as these models can improve scene coherence and production efficiency, addressing common issues in traditional AI tools [21][22]. Group 5: Future Directions - Qunke Technology is developing an AI video generation product that integrates 3D capabilities to further enhance spatial consistency in generated content [24]. - The company aims to bridge the gap between virtual and real-world applications, particularly in robotics, by providing structured 3D data that can be used for training [41].
