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" | 21:9 16:9 3:2 4:3 5:4 1:1 4:5 3:4 2:3 9:16 9:21 |
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. | — | — |
image_prompt_strength | number | Blend between the prompt and the image prompt. | 0.1 | min: 0, max: 1 |
output_format | string | Format of the output images. | "jpg" | jpg png |
raw | boolean | Generate less processed, more natural-looking images | false | — |
safety_tolerance | integer | Safety tolerance, 1 is most strict and 6 is most permissive | 2 | min: 1, max: 6 |
seed | integer | Random seed. Set for reproducible generation | — | — |
