Since someone is once again claiming ownership over a model they don't own, I took precautions ahead of time. The BF16 version is safely stored in my other repository [Granddyser/BigLoveKleinFp8]. This repo will be fully restored within approximately 14 days, just like last time.

All quantized versions of FLUX.2-klein-base-9B by Black Forest Labs, based on the BigLove Klein 2 finetune.

Available Files

File	Format	Size	Use Case
`bigLove_klein2_Bf16.safetensors`	BF16	~18 GB	Full precision, best quality
`bigLove_klein2_bf16_pruned.safetensors`	BF16 (pruned)	~18 GB	Pruned weights, slightly faster
`bigLove_klein2_fp8_pruned.safetensors`	FP8 (pruned)	~9 GB	Good balance of quality & VRAM
`bigLove_klein2_nf4.safetensors`	NF4	~5 GB	Low VRAM, fast inference
`bigLove_klein2.gguf`	GGUF	varies	For GGUF-compatible loaders

Usage

ComfyUI

Place the desired model file in your ComfyUI/models/diffusion_models/ (or unet) folder and select it in the appropriate loader node.

Diffusers

python

from diffusers import FluxPipeline
import torch

pipe = FluxPipeline.from_pretrained(
    "Granddyser/biglove-klein2-fp8",
    torch_dtype=torch.bfloat16
)
pipe.to("cuda")

image = pipe(
    prompt="your prompt here",
    num_inference_steps=4,
    guidance_scale=0.0,
).images[0]

image.save("output.png")
