Request Parameters

ParameterTypeRequiredDefaultRangeDescription
promptstringYes-The positive prompt for the generation.
sizestringNo1024*1024256 ~ 1536 per dimensionThe size of the generated media in pixels (width*height).
strengthnumberNo0.80.00 ~ 1.00Strength indicates extent to transform the reference image.
num_inference_stepsintegerNo281 ~ 50The number of inference steps to perform.
seedintegerNo-1-1 ~ 2147483647The random seed to use for the generation. -1 means a random seed will be used.
guidance_scalenumberNo3.51.0 ~ 20.0The guidance scale to use for the generation.
output_formatstringNojpegjpeg, pngThe format of the output image.
enable_base64_outputbooleanNofalse-If enabled, the output will be encoded into a BASE64 string instead of a URL. This property is only available through the API.
enable_sync_modebooleanNofalse-If set to true, the function will wait for the result to be generated and uploaded before returning the response. It allows you to get the result directly in the response. This property is only available through the API.
