Prompt that guides image generation.

image_size default landscape_4_3

Dimensions of the generated image.

num_images default 1

Image count requested for generation.

Advanced output_format · safety_tolerance · seed · enhance_prompt
output_format default jpeg

File format for the resulting image.

About FLUX1.1 [pro]

Generates images from a text `prompt` using one of six preset `image_size` values, with landscape_4_3 as the default. Returns 1 to 4 images as jpeg or png. `safety_tolerance` takes levels 1 to 6, and `enhance_prompt` can rewrite the prompt before generation. A `seed` makes results repeatable.
