- Rapid prototyping of game assets from concept art descriptions
- Generating photorealistic product models for e-commerce AR try-ons
- Building dynamic digital twins for industrial simulation environments
The API uses OAuth 2.0 with API key authentication and returns JSON responses with direct S3 links to generated models. We recommend using the async endpoint for batch processing and implementing retry logic with exponential backoff due to variable queue times. The official Python and JavaScript SDKs handle model downloads and metadata parsing automatically.

Hunyuan3D-2MV API
The Hunyuan3D-2MV API generates detailed 3D models from two input images with consistent geometry and texture across views, leveraging advanced neural rendering techniques developed by Alibaba’s Tongyi Lab.
- Exceptional detail retention from sparse input views
- Seamless integration with Unity and Unreal Engine via standardized exports
- Low latency even with complex geometry requests
- Requires high-quality input images; fails with low-contrast or occluded scenes
- Limited control over mesh polygon count without post-processing
