Fast FLUX text-to-image generation for lightweight iteration.

FLUX Schnell is the speed-oriented FLUX node. It exposes prompt, megapixels, output count, aspect ratio, output quality, output format, steps, safety, and seed.

Use it for quick text-to-image exploration. Move to other FLUX variants when reference images, structure guidance, fill/edit behavior, or higher finish matters.

Inputs (1)

prompt

String

Prompt for generated image

Multi InputMin: 0Max: 100

Parameters (10)

Seed

Number

Random seed. Set for reproducible generation. Set to -1 if you want it to be randomly generated.

Prompt

String

Prompt for generated image

Default:

go_fast

Boolean

Run faster predictions with model optimized for speed (currently fp8 quantized); disable to run in original bf16. Note that outputs will not be deterministic when this is enabled, even if you set a seed.

Default: true

Megapixels

String

Approximate number of megapixels for generated image

Default: 1

num_outputs

Number

Number of outputs to generate

Default: 1

aspect_ratio

String

Aspect ratio for the generated image

Default: 1:1

output_format

String

Format of the output images

Default: webp

output_quality

Number

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

num_inference_steps

Number

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

Default: 4

disable_safety_checker

Boolean

Disable safety checker for generated images.

Default: false
