Listo
Instrucción

Describe the image to generate, in any language (up to 5,000 characters).

width256

Output image width. Both must be passed at the same time; JSON integers, each side ≥256 and ≤4096; aspect ratio between 1:2.5 and 2.5:1. Once passed, aspect_ratio and resolution are ignored.

height640

Output image height. Both must be passed at the same time; JSON integers, each side ≥256 and ≤4096; aspect ratio between 1:2.5 and 2.5:1. Once passed, aspect_ratio and resolution are ignored.

Relación de aspecto

Output aspect ratio.

Resolución

Output resolution: 1K, 2K or 4K. Higher resolutions cost more and take longer.

output_format

Output image format.

num_images1

Number of images to generate with the same settings.

Semilla

Random seed. Omit for a random result; with the same seed and parameters the result is reproducible. When generating multiple images, image i uses seed + i. 0-2147483647

enhance_prompt

Rewrites the prompt into a fuller description before generating, which noticeably improves quality. Enabled by default; pass false to turn it off. Recommended to turn off when your request must be followed literally (exact text edits, "keep X unchanged and only change Y", fixed compositions) or when latency matters.

nsfw_checker

A configurable parameter. Defaults to true in the Playground.

No se garantiza que se pueda filtrar todo el contenido. Si los resultados no son satisfactorios, tendrás que tomar las medidas que consideres necesarias.
