prompt

string

required

length ≤ 10000

What you wish to see in the output image. A strong, descriptive prompt that clearly defines elements, colors, and subjects will lead to better results.

image

null

required

An image input to edit. Preview API NIM supports only a predefined set of images. The image should be in form of data:image/png;example_id,{example_id} with example_id in a range [0,2].

height

integer

enum

Defaults to 1024

The image height in pixels. Supported heights=[1568, 1504, 1456, 1392, 1328, 1248, 1184, 1104, 1024, 944, 880, 832, 800, 752, 720, 688, 672].

width

integer

enum

Defaults to 1024

The image width in pixels. Supported widths=[672, 688, 720, 752, 800, 832, 880, 944, 1024, 1104, 1184, 1248, 1328, 1392, 1456, 1504, 1568].

cfg_scale

number

≤ 9

Defaults to 3.5

How strictly the diffusion process adheres to the prompt text (higher values keep your image closer to your prompt).

aspect_ratio

string

enum

Defaults to match_input_image

Aspect ratio of the image to generate.

samples

integer

1 to 1

Defaults to 1

Number of images to generate. Only samples=1 is supported

seed

integer

≥ 0

Defaults to 0

The seed which governs generation. Changing the seed with other inputs fixed results in different outputs. (Use 0 for a random seed)

steps

integer

20 to 50

Defaults to 30

The number of diffusion steps applied to generate an output image.
