Practical use cases

• Build automated image generation into product catalogs, CMS tools, or creative dashboards.

Implementation tips

• Use `0.5K` for drafts, thumbnails, and prompt testing.
• Use `2K` or `4K` when the image is closer to final production.
• Keep prompts specific: subject, style, lighting, background, composition, and brand constraints.
• For image-to-image, provide a clean reference image with the product or subject clearly visible.
• Request multiple images only when variation is useful, since billing is per image.
