Input Parameters

Name	Type	Description	Default	Constraints
`finetune_id`*	string	Finetune ID for making images using a previously trained fine-tune. Only IDs from trainings made using Replicate's Flux Pro fine-tuning model are supported.	`—`	—
`prompt`*	string	Text prompt for image generation	`—`	—
`aspect_ratio`	string	Aspect ratio for the generated image	`"1:1"`	21:916:93:24:35:41:14:53:42:39:169:21
`finetune_strength`	number	Controls finetune influence	`1`	min: 0, max: 2
`image_prompt`	string(uri)	Image to use with Flux Redux. This is used together with the text prompt to guide the generation towards the composition of the image_prompt. Must be jpeg, png, gif, or webp.	`—`	—
