•required

Prompt that guides image generation.

image_size default landscape_4_3

Dimensions of the generated image.

num_images default 1

Set how many images to generate; this choice is fixed at 1 when output is streamed.

Advanced output_format · acceleration · num_inference_steps · guidance_scale · seed · enable_safety_checker · loras
output_format default jpeg

File format for the resulting image.

acceleration default none

Image generation acceleration setting. Choose 'regular' for a balance between speed and quality.

default 28

Count of inference steps to run.

default 3.5

Prompt-adherence strength for image selection, expressed as CFG (Classifier Free Guidance).

Seed for reproducible images: an identical prompt and seed produce an identical image when the model version is unchanged.

default []

LoRAs whose combined effect produces the generated image, with no limit on how many you supply.

About Juggernaut Flux Base LoRA

Text-to-image model that accepts a list of `loras` which are merged during generation. Options include six `image_size` presets, 1 to 50 `num_inference_steps`, `guidance_scale` from 0 to 35, and 1 to 4 images per request. Output is jpeg or png, and `acceleration` can be none or regular.

Parameters

Send either the canonical name or the native name, not both. Canonical names
