Tencent Open-Sources Groundbreaking 3D World Model

At the 2025 Tencent Forum of the World Artificial Intelligence Conference, Tencent made waves by officially releasing Hunyuan 3D World Model 1.0 and announcing its full open-source availability. This marks the industry's first open-source world generation model supporting immersive roaming, interaction, and simulation.

Revolutionizing 3D Content Creation

The Hunyuan 3D World Model integrates panoramic visual generation and hierarchical 3D reconstruction, accepting both text and image inputs to generate high-quality, stylistically diverse navigable 3D scenes. This breakthrough dramatically simplifies the 3D scene construction process:

• Reduces weeks-long professional modeling tasks to minutes
• Generates complete game environments (buildings, terrain, vegetation)
• Outputs Mesh files compatible with Unity, Unreal Engine, and Blender
• Enables VR headset integration (including Vision Pro)

Technical Breakthroughs

The model's core innovation is its "Semantic Hierarchical 3D Scene Representation and Generation Algorithm", which:

1. Decomposes complex worlds into semantic levels
2. Intelligently separates foreground/background elements
3. Maintains compatibility with industry-standard tools
4. Supports physical simulations on scene elements

Tencent reports the model outperforms global competitors in aesthetic quality and instruction following for both text-to-world and image-to-world generation.

Expanded Open-Source Strategy

Tencent revealed ambitious open-source plans including:

• Edge-side hybrid reasoning language models
• Multimodal understanding models (Hunyuan Vision)
• Game visual models (Hunyuan GameCraft)
• Smaller-scale models (0.5B to 7B parameters) for easier deployment

The company's flagship TurboS model has maintained monthly updates since launch, showing significant improvements in:

• Code generation
• Scientific capabilities
• Complex instruction following

The newly announced Hunyuan T1 builds on this foundation with enhanced reasoning capabilities.

Industry Impact & Availability

The Hunyuan ecosystem now offers:

• Complete multimodal generation toolset plugins
• Leading text-to-image/video/3D capabilities
• Over 2.3 million downloads of its 3D series models

The model ranks first globally in texture quality according to Shanghai AI Lab evaluations.

Key Points:

• First open-source world generation model supporting full immersion
• Reduces professional modeling time from weeks to minutes
• Compatible with major game engines and VR platforms
• Part of broader Tencent strategy to democratize AI tools
• Community adoption exceeding 2.3 million downloads
