Dreambooth V4 Image to Image Endpoint

Overview​

Dreambooth Image to Image API is used to generate an image from an image based on trained or on public models. Pass the appropriate request parameters to the endpoint to generate image from an image.

This endpoint generates and returns an image from an image passed with its URL in the request.

Together with the image you can add your description of the desired result by passing prompt and negative prompt.

Body Attributes​

ParameterDescription
keyYour API Key used for request authorization
model_idThe ID of the model to be used. It can be public or your trained model.
promptText prompt with description of the things you want in the image to be generated
negative_promptItems you don't want in the image
init_imageLink to the Initial Image
widthMax Height: Width: 1024x1024
heightMax Height: Width: 1024x1024
samplesNumber of images to be returned in response. The maximum value is 4.
num_inference_stepsNumber of denoising steps (minimum: 1; maximum: 50)
safety_checkerA checker for NSFW images. If such an image is detected, it will be replaced by a blank image.
safety_checker_typeModify image if NSFW images are found; default: sensitive_content_text, options: blur/sensitive_content_text/pixelate/black
enhance_promptEnhance prompts for better results; default: yes, options: yes/no
guidance_scaleScale for classifier-free guidance (minimum: 1; maximum: 20)
tomesdEnable tomesd to generate images: gives really fast results, default: yes, options: yes/no
use_karras_sigmasUse keras sigmas to generate images. gives nice results, default: yes, options: yes/no
algorithm_typeUsed in DPMSolverMultistepScheduler scheduler, default: none, options: dpmsolver+++
vaeuse custom vae in generating images default: null
lora_strengthStrength of lora model you are using. If using multi lora, pass each values as comma saparated
lora_modelmulti lora is supported, pass comma saparated values . Example contrast-fix,yae-miko-genshin
strengthPrompt strength when using init image. 1.0 corresponds to full destruction of information in the init image.
seedSeed is used to reproduce results, same seed will give you same image in return again. Pass null for a random number.
schedulerUse it to set a scheduler.
webhookSet an URL to get a POST API call once the image generation is complete.
track_idThis ID is returned in the response to the webhook API call. This will be used to identify the webhook request.
clip_skipClip Skip (minimum: 1; maximum: 8)
base64Get response as base64 string, pass init_image as base64 string, to get base64 response. default: "no", options: yes/no
tempCreate temp image link. This link is valid for 24 hours. temp: yes, options: yes/no
