Image Size- Select the resolution for image generation: 2K (2048×2048, balanced quality and speed), 4K (4096×4096, ultra-high quality), or 'custom' to specify exact dimensions.
Aspect Ratio- Choose the aspect ratio for the generated image: match_input_image (preserves original ratio), 16:9 (landscape), 9:16 (portrait), 1:1 (square), 4:3 (classic), or custom ratios.
Custom Width- Custom image width in pixels (only used when size='custom'). Range: 1024-4096 pixels. Higher resolutions require more processing time but deliver superior quality.
Custom Height- Custom image height in pixels (only used when size='custom'). Range: 1024-4096 pixels. Must be compatible with the width for optimal results.
Sequential Generation- Enable automatic sequential image generation to create a series of related images. 'auto' mode generates up to max_images in sequence. Perfect for storyboards or product variations.
