Input

redux_image
file

Input image to condition your output on. This replaces prompt for FLUX.1 Redux models

string

Aspect ratio for the generated image

Default: "1:1"

integer
(minimum: 1, maximum: 4)

Number of outputs to generate

Default: 1

integer
(minimum: 1, maximum: 4)

Number of denoising steps. 4 is recommended, and lower number of steps produce lower quality outputs, faster.

Default: 4

integer

Random seed. Set for reproducible generation

string

Format of the output images

Default: "webp"

integer
(minimum: 0, maximum: 100)

Quality when saving the output images, from 0 to 100. 100 is best quality, 0 is lowest quality. Not relevant for .png outputs

Default: 80

boolean

This model’s safety checker can’t be disabled when running on the website. Learn more about platform safety on Replicate.

Disable safety checker for generated images.

Default: false

string

Approximate number of megapixels for generated image

Default: "1"

Pricing

Official model
Pricing for official models works differently from other models. Instead of being billed by time, you’re billed by input and output, making pricing more predictable.

This model is priced by how many images are generated.

TypePer unitPer $1
Output
$0.003 / image
or
333 images / $1

For example, generating 100 images should cost around $0.30.

Readme

FLUX.1 Redux [schnell] lets you quickly generate variations of your images. It’s optimized for speed, making it perfect for prototyping and creative exploration. While it trades some quality for speed compared to Redux [dev], it’s ideal for rapid iteration or building real-time creative tools.
