Tencent drops HY-World 2.0 for editable 3D worlds

HY-World 2.0 marks a critical pivot in world models, moving away from hallucinated video generation and toward actual 3D asset creation for game development and simulation. It solves the biggest pain points of pixel-based models: 3D consistency and practical utility.

• –Generates persistent, editable 3D assets (meshes, 3DGS) that can be imported directly into Unity, Unreal Engine, and Isaac Sim.
• –Achieves real-time rendering and true 3D consistency, bypassing the flickering and high per-frame inference costs of video models like Sora or Genie.
• –Supports interactive character mode with physical collisions, enabling zero-error control that video generation cannot match.
• –Open-sourcing this pipeline positions Tencent to become a foundational layer for AI-native game development and spatial computing.
