Flexible image generation with customizable inference steps and guidance scale, supporting up to ten reference images

Input

Text prompt for image generation

List of input images for image-to-image generation. Maximum 10 images. Must be jpeg, png, gif, or webp.

No items added.

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 for the generated image. Use 'match_input_image' to match the first input image's aspect ratio.

Format of the output images.

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, 1 is most strict and 5 is most permissive

Width of the generated image. Only used when aspect_ratio=custom. Must be a multiple of 32 (if it's not, it will be rounded to nearest multiple of 32).

Height of the generated image. Only used when aspect_ratio=custom. Must be a multiple of 32 (if it's not, it will be rounded to nearest multiple of 32).

Random seed. Set for reproducible generation

Number of inference steps

Guidance scale for generation. Controls how closely the output follows the prompt

Automatically modify the prompt for more creative generation
