--- title: Hunyuan 3D 3.1 Rapid | Runware Docs url: https://runware.ai/docs/models/tencent-hunyuan-3d-3-1-rapid description: Fast 3D asset generation optimized for rapid prototyping and iteration --- # Hunyuan 3D 3.1 Rapid Hunyuan 3D 3.1 Rapid is a speed-optimized 3D generation model from Tencent designed for fast prototyping and iteration. It generates 3D assets from text prompts or single images in seconds, producing clean meshes with PBR materials. Ideal for concept evaluation, rapid asset library building, and early-stage design workflows where speed is prioritized over maximum geometric detail. - **ID**: `tencent:hunyuan-3d@3.1-rapid` - **Status**: coming-soon - **Release Date**: February 10, 2026 - **Capabilities**: Text to 3D, Image to 3D ## Compatibility & Validation `positivePrompt` cannot be used with `inputs.image`. --- When `settings.geometryOnly` is `true`, `outputFormat` cannot be used. --- When `settings.geometryOnly` is `true`, `settings.pbr` cannot be used. ## Request Parameters **API Options** Platform-level options for task execution and delivery. ### [taskType](https://runware.ai/docs/models/tencent-hunyuan-3d-3-1-rapid#request-tasktype) - **Type**: `string` - **Required**: true - **Value**: `3dInference` Identifier for the type of task being performed ### [taskUUID](https://runware.ai/docs/models/tencent-hunyuan-3d-3-1-rapid#request-taskuuid) - **Type**: `string` - **Required**: true - **Format**: `UUID v4` UUID v4 identifier for tracking tasks and matching async responses.

The raw binary data of the media file is sent directly as the request body. For secure uploads to cloud storage, use presigned URLs that include temporary authentication credentials. **Common use cases:** - **Cloud storage**: Upload directly to S3 buckets, Google Cloud Storage, or Azure Blob Storage using presigned URLs. - **CDN integration**: Upload to content delivery networks for immediate distribution. ```text // S3 presigned URL for secure upload https://your-bucket.s3.amazonaws.com/generated/content.mp4?X-Amz-Signature=abc123&X-Amz-Expires=3600 // Google Cloud Storage presigned URL https://storage.googleapis.com/your-bucket/content.jpg?X-Goog-Signature=xyz789 // Custom storage endpoint https://storage.example.com/uploads/generated-image.jpg ``` The content data will be sent as the request body to the specified URL when generation is complete. ### [ttl](https://runware.ai/docs/models/tencent-hunyuan-3d-3-1-rapid#request-ttl) - **Type**: `integer` - **Min**: `60` Time-to-live (TTL) in seconds for generated content.
