Note: It appears that the bug with ComfyUI and DF11 FLUX.2 [klein] models does not occur in `diffusers`, I am still investigating the issue with the ComfyUI implementation.

For more information (including how to compress models yourself), check out https://huggingface.co/DFloat11 and https://github.com/LeanModels/DFloat11

Feel free to request for other models for compression as well (for either the diffusers library, ComfyUI, or any other model), although models that use architectures which are unfamiliar to me might be more difficult.

How to Use

`diffusers`

python

import torch
from diffusers import Flux2KleinPipeline, Flux2Transformer2DModel
from transformers.modeling_utils import no_init_weights
from dfloat11 import DFloat11Model
text_encoder = DFloat11Model.from_pretrained("DFloat11/Qwen3-8B-DF11", device="cpu")
with no_init_weights():
	transformer = Flux2Transformer2DModel.from_config(
		Flux2Transformer2DModel.load_config(
			"black-forest-labs/FLUX.2-klein-base-9B", subfolder="transformer"
		),
		torch_dtype=torch.bfloat16
	).to(torch.bfloat16)
DFloat11Model.from_pretrained("mingyi456/FLUX.2-klein-base-9B-DF11", device="cpu", bfloat16_model=transformer)
pipe = Flux2KleinPipeline.from_pretrained("black-forest-labs/FLUX.2-klein-base-9B", text_encoder=text_encoder, transformer=transformer, torch_dtype=torch.bfloat16)
pipe.to("cuda")
prompt = "A cat holding a sign that says hello world"
image = pipe(
    prompt=prompt,
    height=1024,
    width=1024,
    guidance_scale=4.0,
    num_inference_steps=50,
    generator=torch.Generator(device="cpu").manual_seed(0)
).images[0]
image.save("flux-klein.png")
