Input

Prompt*216 / 5000 characters

The text prompt used to generate the image

Image Size

The size of the generated image.

Image Resolution

Final image resolution is determined by combining image_size (aspect ratio) and image_resolution (pixel scale). For example, choosing 4:3 + 4K gives 4096 × 3072px

Max Images

Set this value (1–6) to cap how many images a single generation run can produce in one set—because they’re created in one shot rather than separate requests, you must also state the exact number you want in the prompt so both settings align.

Seed

Random seed to control the stochasticity of image generation

NSFW filter

OnLocked — this platform doesn't generate adult content.
