Pricing

Billing Rules

• 1k and 2k: $0.028 per image

Best Use Cases

• Photorealistic Portraits — Generate high-detail character images with precise lighting and texture control.

Pro Tips

• The more specific your prompt, the better — include camera angle, lighting style, color palette, and subject details.
• Use reference images to lock in a visual style or maintain character consistency across multiple generations.
• Use auto aspect ratio when you want the model to determine the best composition for your prompt.
• Generate 3–4 images per run at 1k to explore variations before committing to a 4k final render.
• Use element_list for consistent characters or branded elements across a series of images.

Notes

• Only prompt is required; all other parameters are optional.
• 4k resolution costs 2× the base price per image.
• Using element_list: First use Kling Elements to generate your element and note its name and ID. Then simply write the element name naturally in your prompt, and enter the corresponding element ID in the element_list field. No special characters or syntax required.
