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 text pipeline. Not all parameters might be available for a given model.

prompt
string
required

Text prompt(s) to guide image generation. Separate multiple prompts with '|' if supported by the model.

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}.

height
integer
default: 576

The height in pixels of the generated image.

width
integer

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
