Parameters

Task Submission Parameters

Request Parameters

ParameterTypeRequiredDefaultRangeDescription
promptstringYes-The positive prompt for the generation.
sizestringNoautoauto, 1024*1024, 1024*1536, 1536*1024The size of the generated media in pixels (width*height).
qualitystringNomediumlow, medium, highThe quality of the generated image.
backgroundstringNoopaqueauto, transparent, opaqueBackground for the generated image
output_formatstringNojpegjpeg, pngThe format of the output image.
enable_sync_modebooleanNofalse-If set to `true`, the request attempts to wait for the generated result and return outputs in the same response. If the result is not ready within the sync wait window, the API can return a timeout body while the task continues processing. This option is only available via the API and is supported only by some models.
enable_base64_outputbooleanNofalse-If set to `true`, the prediction's `output` strings are returned as **naked base64** (no `data:<mime>;base64,` prefix). When `false` (default), outputs are returned as URLs pointing to our CDN.
