Input

Field	Kind	Default	Description

`image_urls` required	URLs or files	—	Reference images to edit or combine (1-8). Order sets the <image-N> tags.
`model`	one of berry, jam	berry	Model variant: berry favors quality, jam favors speed.
`image_size`	JSON	auto	Output size, rounded up to multiples of 16, at most 4,220,160 total pixels (1680×2512). auto lets the prompt expander pick the aspect ratio at about 2048×2048.
`reasoning_level`	one of low, medium, high, ultra	medium	How much effort the harness spends reasoning about the given editing task. Higher reasoning effort means slower generation time. high plans the edit with segmentation, web search and reference photos, keeps unedited areas of a single input image, corrects required text, and bills a flat $0.125 (5 megapixels) more per request. low and medium bill $0.025 per megapixel of the output plus each reference (references larger than the output count as the output size). ultra generates at 2K with Krea's ultra thinking mode, ignores image_size and negative_prompt, and bills a flat price by reference count: $0.27 for 1, $0.30 for 2, $0.32 for 3, $0.35 for 4, plus $0.0275 per reference past 4.
