Input

Field	Kind	Default	Description
`image` required	URL or file	—	The image to inpaint. Can contain alpha mask. If the image width or height are not multiples of 32, they will be scaled to the closest multiple of 32. If the image dimensions don't fit within 1440x1440, it will be scaled down to fit.
`prompt` required	text	—	Prompt for generated image
`mask`	text	—	A black-and-white image that describes the part of the image to inpaint. Black areas will be preserved while white areas will be inpainted.
`seed`	number (whole)	—	Random seed. Set for reproducible generation
`guidance`	number 0 to 100	30	Guidance for generated image
`lora_scale`	number -1 to 3	1	Determines how strongly the main LoRA should be applied. Sane results between 0 and 1 for base inference. For go_fast we apply a 1.5x multiplier to this value; we've generally seen good performance when scaling the base value by that amount. You may still need to experiment to find the best value for your particular lora.
`megapixels`	JSON	1	Approximate number of megapixels for generated image. Use match_input to match the size of the input (with an upper limit of 1440x1440 pixels)
`num_outputs`	number (whole) 1 to 4	1	Number of outputs to generate
`lora_weights`	text	—	Load LoRA weights. Supports Replicate models in the format <owner>/<username> or <owner>/<username>/<version>, HuggingFace URLs in the format huggingface.co/<owner>/<model-name>, CivitAI URLs in the format civitai.com/models/<id>[/<model-name>], or arbitrary .safetensors URLs from the Internet. For example, 'fofr/flux-pixar-cars'
`output_format`	JSON	webp	Format of the output images
`output_quality`	number (whole) 0 to 100	80	Quality when saving the output images, from 0 to 100. 100 is best quality, 0 is lowest quality. Not relevant for .png outputs
`num_inference_steps`	number (whole) 1 to 50	28	Number of denoising steps. Recommended range is 28-50, and lower number of steps produce lower quality outputs, faster.
