| API | A hosted REST API exposes generation and pipeline operations, with background jobs, webhooks and idempotency keys. | The Hunyuan3D-2.1 repository includes API documentation and an API server. |
| API capabilities | The REST API supports generation and pipeline steps, with webhooks and idempotency keys. | Tencent Cloud documents API tasks for professional and rapid 3D generation, texture generation, topology reduction, component generation, UV mapping, motion generation, auto-rigging, and format conversion. |
| Image to 3D | A product or object photograph can be converted into a textured mesh, with clearer single-object images recommended for better results. | Hunyuan3D-2.1 includes an image-to-shape model. |
| Integrations | Official materials describe support for Unity, Unreal, Blender, printer-oriented tools and model-viewer based AR commerce. | Tencent says generated assets can be integrated into Unity, Unreal Engine, and Blender workflows. |
| Intended users | The company presents Alpha3D for game developers, 3D printing, makers, AR/VR, and e-commerce. | Tencent says the released weights and training code enable community developers to fine-tune and extend the model for downstream applications. |
| Product | Alpha3D generates production-ready 3D models from a text description, a single image, or multiple angle photos, and provides post-generation tools in the same platform. | Tencent describes Hunyuan 3D as an API service that creates 3D models from text descriptions or uploaded 2D images. |
| Support | The company lists general, developer/API, business/enterprise, and partnership contact emails, and says its FAQ team aims to respond within one business day. | The Hunyuan3D-2.1 repository points users to WeChat and Discord groups to discuss the project and get help. |
