Krea 2 Turbo

Krea 2 Turbo is the speed-optimized variant of Krea 2. It is designed to preserve as much of the original Krea 2 creative workflow as possible while running significantly faster, making it well suited to rapid ideation, prompt experimentation, early concept work, and other iteration-heavy image generation tasks where responsiveness matters more than the stronger final-image polish of the larger Krea 2 variants.

API Options
Platform-level options for task execution and delivery.
taskType
stringrequiredvalue: imageInferenceIdentifier 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: URLImage output type.
Allowed values3 values
outputFormat
stringdefault: JPGSpecifies the file format of the generated output. The available values depend on the task type and the specific model's capabilities.
- `JPG`: Best for photorealistic images with smaller file sizes (no transparency).
- `PNG`: Lossless compression, supports high quality and transparency (alpha channel).
- `WEBP`: Modern format providing superior compression and transparency support.
**Transparency**: If you are using features like background removal or LayerDiffuse that require transparency, you must select a format that supports an alpha channel (e.g., `PNG`, `WEBP`, `TIFF`). `JPG` does not support transparency.Allowed values3 values
outputQuality
integermin: 20max: 99default: 95Compression quality of the output. Higher values preserve quality but increase file size.
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: syncDetermines 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.
safety
objectContent safety checking configuration for image generation.
Properties1 property
safety»checkContentcheckContent
booleandefault: falseEnable or disable content safety checking.
ttl
integermin: 60Time-to-live (TTL) in seconds for generated content. Only applies when
outputTypeisURL.
includeCost
booleandefault: falseInclude task cost in the response.
numberResults
integermin: 1max: 20default: 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»referenceImagesreferenceImages
array of strings or objectsmin items: 1max items: 10Style reference images for guiding generation. Each item can be a plain image input (UUID, URL, DataURI, or Base64) or an object with an image and a per-image strength.
Examples3 examples
Shorthand format: When you don't need to specify a custom strength, you can pass a plain image input directly. It will use the default influence strength.
"referenceImages": [ "aac49721-1964-481a-ae78-8a4e29b91402" ]Object format: When you need to control the exact influence of the reference image, use an object with
imageandstrength. Positive values guide the output toward the reference; negative values guide away from it."referenceImages": [ { "image": "aac49721-1964-481a-ae78-8a4e29b91402", "strength": 0.7 } ]Multiple images: You can provide multiple reference images and even mix both formats.
"referenceImages": [ "aac49721-1964-481a-ae78-8a4e29b91402", { "image": "3ad204c3-a9de-4963-8a1a-c3911e3afafe", "strength": 1.2 } ]Format 1: string[]
Image input (UUID, URL, Data URI, or Base64).
