image-to-image

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.

model_id
string
default:
required

Hugging Face model ID used for image generation.

prompt
string
required

Text prompt(s) to guide image generation.

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.

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}.

num_images_per_prompt
integer
default:
1

Number of images to generate per prompt.

num_inference_steps
integer
default:
100
