This checkpoint is a Pro version of FLUX.1-dev-Controlnet-Union trained with more steps and datasets.
This model supports 7 control modes, including canny (0), tile (1), depth (2), blur (3), pose (4), gray (5), low quality (6).
The recommended controlnet_conditioning_scale is 0.3-0.8.
This model can be jointly used with other ControlNets.

Multi-Controls Inference

python

from diffusers.utils import load_image

from diffusers import FluxControlNetPipeline, FluxControlNetModel
from diffusers.models import FluxMultiControlNetModel

base_model = 'black-forest-labs/FLUX.1-dev'
controlnet_model_union = 'Shakker-Labs/FLUX.1-dev-ControlNet-Union-Pro'

controlnet_union = FluxControlNetModel.from_pretrained(controlnet_model_union, torch_dtype=torch.bfloat16)
controlnet = FluxMultiControlNetModel([controlnet_union]) # we always recommend loading via FluxMultiControlNetModel

pipe = FluxControlNetPipeline.from_pretrained(base_model, controlnet=controlnet, torch_dtype=torch.bfloat16)
pipe.to("cuda")

prompt = 'A bohemian-style female travel blogger with sun-kissed skin and messy beach waves.'

width, height = control_image_depth.size

We also support loading multiple ControlNets as before, you can load as

python

from diffusers import FluxControlNetModel
from diffusers.models import FluxMultiControlNetModel

controlnet_model_union = 'Shakker-Labs/FLUX.1-dev-ControlNet-Union-Pro'
controlnet_union = FluxControlNetModel.from_pretrained(controlnet_model_union, torch_dtype=torch.bfloat16)

controlnet_model_depth = 'Shakker-Labs/FLUX.1-dev-Controlnet-Depth'
controlnet_depth = FluxControlNetModel.from_pretrained(controlnet_model_depth, torch_dtype=torch.bfloat16)

controlnet = FluxMultiControlNetModel([controlnet_union, controlnet_depth])

# set mode to None for other ControlNets
control_mode=[2, None]
