Example Output

Prompt:

"A photorealistic wide shot of a large minimalist digital billboard standing in the middle of a forest filled with purple and lavender-hued trees. Soft violet foliage surrounds the scene, creating a surreal yet elegant atmosphere. The billboard has a sleek metal frame with subtle overhead lights, blending advanced technology with dreamlike nature. On the screen, a dark glass display shows a clean, futuristic UI with gentle lavender and magenta accents. The billboard is transparent, showing the trees behind it. Centered text reads: “FLUX.2 [max]” in a modern sans-serif font, calm, confident, and precise. Soft daylight with a purple color cast, cinematic composition, ultra-high resolution, premium AI launch aesthetic, minimalism, tranquil mood."

Input Parameters

seed Type: integer: Random seed. Set for reproducible generation
width Type: integerRange: 256 - 2048: Width of the generated image. Only used when aspect_ratio=custom. Must be a multiple of 16 (if it's not, it will be rounded to nearest multiple of 16).
height Type: integerRange: 256 - 2048: Height of the generated image. Only used when aspect_ratio=custom. Must be a multiple of 16 (if it's not, it will be rounded to nearest multiple of 16).
prompt (required) Type: string: Text prompt for image generation
resolution Default: 1 MP: Resolution in megapixels. Up to 4 MP is possible, but 2 MP or below is recommended. The maximum image size is 2048x2048, which means that high-resolution images may not respect the resolution if aspect ratio is not 1:1. Resolution is not used when aspect_ratio is 'custom'. When aspect_ratio is 'match_input_image', use 'match_input_image' to match the input image's resolution (clamped to 0.5-4 MP).
aspect_ratio Default: 1:1: Aspect ratio for the generated image. Use 'match_input_image' to match the first input image's aspect ratio.
input_images Type: arrayDefault:: List of input images for image-to-image generation. Maximum 8 images. Must be jpeg, png, gif, or webp.
output_format Default: webp: Format of the output images.
output_quality Type: integerDefault: 80Range: 0 - 100: Quality when saving the output images, from 0 to 100. 100 is best quality, 0 is lowest quality. Not relevant for .png outputs
safety_tolerance Type: integerDefault: 2Range: 1 - 5: Safety tolerance, 1 is most strict and 5 is most permissive
