Parameters

NameTypeDefaultDescription
prompt requiredstringAction hero into an apocalypse survivor zo…Text describing the image to generate. Include subjects like 'sunset mountain view'.
image_inputstring[]List of image URLs to guide generation. Use for reference; add 1-3 URLs.
sizeenum2KImage resolution preset. '1K/2K/4K' sets one dimension (1024/2048/4096), other dimension calculated from aspect_ratio. Use 'custom' to specify exact width/height. Note: Combining with aspect_ratio may not maximize quality for all ratios.
aspect_ratioenumImage proportions. When combined with size preset, one dimension is fixed (1K=1024, 2K=2048, 4K=4096). For best quality with non-square ratios, consider using 'custom' size with manual dimensions. Options: '1:1' square, '16:9' widescreen, '9:16' portrait, etc.
widthinteger2048Custom width in pixels (only used when size='custom'). Range: 1024-4096. Both width and height must be set for custom sizing. Dimensions will be validated and rounded to nearest 64 pixels.
heightinteger2048Custom height in pixels (only used when size='custom'). Range: 1024-4096. Both width and height must be set for custom sizing. Dimensions will be validated and rounded to nearest 64 pixels.
sequential_image_generationenumdisabledControls image creation order. Enable 'auto' for batch generation, 'disabled' otherwise.
max_imagesinteger1Sets image generation limit. Choose 1 for single outcome, 5 for multiple.
