black-forest-labs/flux-pro-finetuned

Inference model for FLUX.1 [pro] using custom `finetune_id`

Capabilities

1:1 4:3 3:4 16:9 9:16 2:3 3:2 Reference Images Seed

Cost

Community model (estimated from hardware time)

Input Parameters

finetune_id required 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 required string

Text prompt for image generation

aspect_ratio string

Aspect ratio for the generated image

Default: "1:1"
custom 1:1 16:9 3:2 2:3 4:5 5:4 9:16 3:4 4:3
finetune_strength number

Controls finetune influence

Default: 1 min: 0, max: 2
guidance number

Controls the balance between adherence to the text prompt and image quality/diversity. Higher values make the output more closely match the prompt but may reduce overall image quality. Lower values allow for more creative freedom but might produce results less relevant to the prompt.

Default: 3 min: 2, max: 5
height integer

Height of the generated image in text-to-image mode. Only used when aspect_ratio=custom. Must be a multiple of 32 (if it's not, it will be rounded to nearest multiple of 32). Note: Ignored in img2img and inpainting modes.

min: 256, max: 1440
image_prompt string

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.

output_format string

Format of the output images.

Default: "jpg"
jpg png
prompt_upsampling boolean

Automatically modify the prompt for more creative generation

Default: false
safety_tolerance integer

Safety tolerance, 1 is most strict and 6 is most permissive

Default: 2 min: 1, max: 6
seed integer

Random seed. Set for reproducible generation

steps integer

Number of diffusion steps

Default: 40 min: 1, max: 50
width integer

Width of the generated image in text-to-image mode. Only used when aspect_ratio=custom. Must be a multiple of 32 (if it's not, it will be rounded to nearest multiple of 32). Note: Ignored in img2img and inpainting modes.
