| Name | Type | Default | Description |
|---|---|---|---|
| prompt required | string | A straight-down product still-life photogr… | Text describing the image. Supports in-image typography across scripts — lead with subject, style, lighting. |
| image_urls | string[] | — | Optional reference images to edit or draw context from. Providing any image switches to edit mode. |
| size | enum | 1536x1024 | Output resolution (WIDTHxHEIGHT). Each edge must be a multiple of 16, aspect ratio between 1:3 and 3:1, longest edge at most 3840, and total pixels between 655,360 and 8,294,400. "Auto" lets the model pick. |
| mask_image_url | string | — | Optional mask for surgical inpainting, used only alongside a reference image. Must be a PNG with an alpha channel, matching the reference image's dimensions: the transparent areas are regenerated, everything opaque stays pixel-perfect. A flat black-and-white mask with no alpha channel is rejected. |
| quality | enum | high | Rendering fidelity. "High" keeps typography crisp; use lower values only for previews. |
| background | enum | opaque | "Opaque" renders a filled background; "Transparent" returns a PNG or WEBP with an alpha channel; "Auto" lets the model decide. |
| moderation | enum | auto | Content filter strictness. "Auto" is the safe default. |
| output_format | enum | png | "PNG" for crisp text, "WEBP" for smaller size, "JPEG" for broad compatibility. |
| output_compression | integer | 100 | Compression level 0-100. 100 preserves text crispness; lower values reduce file size. |
