alimama-creative/FLUX.1-Turbo-Alpha

This repository provides a 8-step distilled lora for FLUX.1-dev model released by AlimamaCreative Team.

Description

This checkpoint is a 8-step distilled Lora, trained based on FLUX.1-dev model. We use a multi-head discriminator to improve the distill quality. Our model can be used for T2I, inpainting controlnet and other FLUX related models. The recommended guidance_scale=3.5 and lora_scale=1. Our Lower steps version will release later.

• Text-to-Image.

• With alimama-creative/FLUX.1-dev-Controlnet-Inpainting-Beta. Our distilled lora can be well adapted to the Inpainting controlnet, and the accelerated generated effect can follow the original output well.

How to use

This model can be used ditrectly with diffusers

import torch
from diffusers.pipelines import FluxPipeline

model_id = "black-forest-labs/FLUX.1-dev"

pipe.to("cuda")

pipe.load_lora_weights(adapter_id)
pipe.fuse_lora()

Training Details

The model is trained on 1M open source and internal sources images, with the aesthetic 6.3+ and resolution greater than 800. We use adversarial training to improve the quality. Our method fix the original FLUX.1-dev transformer as the discriminator backbone, and add multi heads to every transformer layer. We fix the guideline scale as 3.5 during training, and use the time shift as 3.
