The default Gateway used in this guide is the public Livepeer.cloud Gateway. It is free to use but not intended for production-ready applications. For production-ready applications, consider using the Livepeer Studio Gateway, which requires an API token. Alternatively, you can set up your own Gateway node or partner with one via the ai-video channel on Discord.

Please note that the exact parameters, default values, and responses may vary between models. For more information on model-specific parameters, please refer to the respective model documentation available in the image-to-image pipeline. Not all parameters might be available for a given model.

Authorizations

Authorization

string

header

required

Bearer authentication header of the form Bearer <token>, where <token> is your auth token.

Body

multipart/form-data

prompt

string

required

Text prompt(s) to guide image generation.

image

file

required

Uploaded image to modify with the pipeline.

model_id

string

default:""

Hugging Face model ID used for image generation.

loras

string

default:""

A LoRA (Low-Rank Adaptation) model and its corresponding weight for image generation. Example: { "latent-consistency/lcm-lora-sdxl": 1.0, "nerijs/pixel-art-xl": 1.2}.

strength

number

default:0.8

Degree of transformation applied to the reference image (0 to 1).

guidance_scale

number

default:7.5

Encourages model to generate images closely linked to the text prompt (higher values may reduce image quality).

image_guidance_scale

number

default:1.5

Degree to which the generated image is pushed towards the initial image.

negative_prompt

string

default:""

Text prompt(s) to guide what to exclude from image generation. Ignored if guidance_scale < 1.

safety_check

boolean

default:true

Perform a safety check to estimate if generated images could be offensive or harmful.

seed

integer

Seed for random number generation.

num_inference_steps

integer

default:100

Number of denoising steps. More steps usually lead to higher quality images but slower inference. Modulated by strength.

num_images_per_prompt

integer

default:1

Number of images to generate per prompt.

Response

Successful Response

Response model for image generation.

images

Media · object[]

required

The generated images.
