Request Body

application/json

TypeScript Definitions

Use the request body type in TypeScript.

model*string

model name

seed?integer

Random seed (-1 for random)

Default-1

size?string

Output image size

image?string

loras?array<>

List of LoRAs to apply (max 5)

Itemsitems <= 5

Default

[  {    "path": "strangerzonehf/Flux-Super-Realism-LoRA",    "scale": 1  }]

prompt*string

Input prompt for image generation

strength?number

Strength indicates extent to transform the reference image

Range0 <= value <= 1

Default0.8

mask_image?The mask image

The mask image tells the model where to generate new pixels (white) and where to preserve the original image (black). It acts as a stencil or guide for targeted image editing.

num_images?integer

Number of images to generate

Range1 <= value <= 4

Default1

guidance_scale?Guidance scale

Flux embedded guidance strength. Higher values make the image follow the prompt more closely. This is not True CFG and does not require a negative prompt. Default 2.5.

Range0 <= value <= 20

Default2.5

cfg_scale?True CFG scale

True classifier-free guidance. Keep at 1.0 (off) for normal use. Set it above 1.0 to enable negative prompting; a non-empty negative_prompt requires cfg_scale > 1, otherwise the request is rejected. On its own (with an empty negative_prompt) it has no effect on the result. Default 1.0.

Range0 <= value <= 20

Default1

negative_prompt?Negative prompt

What to steer the image away from. Only takes effect when cfg_scale > 1; setting a non-empty negative_prompt while cfg_scale <= 1 is rejected with HTTP 400.

num_inference_steps?Num inference steps

The number of inference steps to perform.

Range1 <= value <= 50

Default28
