Rodin Gen-2

Rodin Gen-2 is a 10 billion parameter 3D generation model from Hyper3D built on the BANG architecture. It creates production-ready assets from text prompts or up to 5 input images, with 4x geometry improvement over Gen-1. It supports quad-dominant and raw mesh modes, PBR and shaded materials, configurable polygon counts, T/A pose control, bounding box constraints, and output in GLB, FBX, OBJ, USDZ, and STL formats.

API Options
Platform-level options for task execution and delivery.
taskType
stringrequiredvalue: 3dInferenceIdentifier for the type of task being performed
taskUUID
stringrequiredUUID v4UUID v4 identifier for tracking tasks and matching async responses. Must be unique per task.
outputType
stringdefault: URL3D output type.
Allowed values1 value
outputFormat
stringdefault: GLBSpecifies the file format of the generated output. The available values depend on the task type and the specific model's capabilities.
- `GLB`: Binary glTF format for 3D models, including geometry, textures, and PBR materials.
Allowed values1 value
webhookURL
stringuriSpecifies a webhook URL where JSON responses will be sent via HTTP POST when generation tasks complete. For batch requests with multiple results, each completed item triggers a separate webhook call as it becomes available.

deliveryMethod
stringdefault: asyncDetermines how the API delivers task results.
Allowed values2 values
- Returns complete results directly in the API response.
- Returns an immediate acknowledgment with the task UUID. Poll for results using getResponse.

uploadEndpoint
stringuriSpecifies a URL where the generated content will be automatically uploaded using the HTTP PUT method. 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.
// 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.jpgThe content data will be sent as the request body to the specified URL when generation is complete.
ttl
integermin: 60Time-to-live (TTL) in seconds for generated content. Only applies when
outputTypeisURL.
includeCost
booleanInclude task cost in the response.
numberResults
integermin: 1max: 4default: 1Number of results to generate. Each result uses a different seed, producing variations of the same parameters.
Inputs
Input resources for the task (images, audio, etc). These must be nested inside the inputs object.
inputs object.inputs»imagesimages
array of stringsmin items: 1max items: 5Image inputs for image-to-3D generation (UUID, URL, Data URI, or Base64). First image is used for material generation.
Core Parameters
Primary parameters that define the task output.
model
stringrequiredvalue: hyper3d:rodin@gen-2Identifier of the model to use for generation.
