Request body

12 properties · 1 required · 1 $defs
propertytypedescriptionconstraints
prompt*stringThe text prompt to guide image generation.
enable_safety_checkerbooleanIf set to true, input data will be checked for safety before processing. Disabling it requires account authorization; unauthorized requests are always checked.default: false
seedintegerRandom seed for reproducibility. If None, a random seed is chosen.nullable
enable_prompt_expansionbooleanWhether to enable prompt expansion. This will use a large language model to expand the prompt with additional details while maintaining the original meaning.default: false
negative_promptstringNegative prompt for video generation.default: ""
accelerationenumAcceleration level to use. The more acceleration, the faster the generation, but with lower quality. The recommended value is 'regular'.none | regular · default: "regular"
shiftnumberShift value for the image. Must be between 1.0 and 10.0.1 ≤ n ≤ 10 · default: 2
image_sizeImageSize | enumThe size of the generated image.default: "square_hd"
guidance_scale_2numberGuidance scale for the second stage of the model. This is used to control the adherence to the prompt in the second stage of the model.1 ≤ n ≤ 10 · default: 4
enable_output_safety_checkerbooleanIf set to true, output video will be checked for safety after generation.default: false
num_inference_stepsintegerNumber of inference steps for sampling. Higher values give better quality but take longer.2 ≤ n ≤ 40 · default: 27
guidance_scalenumberClassifier-free guidance scale. Higher values give better adherence to the prompt but may decrease quality.1 ≤ n ≤ 10 · default: 3.5
