¶ Using SDXL Lightning with Diffusers and ComfyUI
SDXL Lightning integrates seamlessly with popular frameworks like Diffusers and ComfyUI, offering flexible workflows tailored to your specific requirements. Below, we outline how to use SDXL Lightning for fast and efficient image generation.
¶ Diffusers Usage
To achieve optimal performance with SDXL Lightning in Diffusers, it’s crucial to select the correct checkpoint for your inference step settings. Follow these examples to implement 2-step, 4-step, 8-step, and 1-step workflows effectively.
¶ 2-Step, 4-Step, 8-Step UNet
This configuration ensures high-quality output with minimal inference steps:
import torch
from diffusers import StableDiffusionXLPipeline, UNet2DConditionModel, EulerDiscreteScheduler
from huggingface_hub import hf_hub_download
from safetensors.torch import load_file
base = "stabilityai/stable-diffusion-xl-base-1.0"
repo = "ByteDance/SDXL-Lightning"
ckpt = "sdxl_lightning_4step_unet.safetensors" # Use the correct checkpoint!
# Load model.
unet = UNet2DConditionModel.from_config(base, subfolder="unet").to("cuda", torch.float16)
unet.load_state_dict(load_file(hf_hub_download(repo, ckpt), device="cuda"))
pipe = StableDiffusionXLPipeline.from_pretrained(base, unet=unet, torch_dtype=torch.float16, variant="fp16").to("cuda")
# Set scheduler and steps.
pipe.scheduler = EulerDiscreteScheduler.from_config(pipe.scheduler.config, timestep_spacing="trailing")
pipe("A girl smiling", num_inference_steps=4, guidance_scale=0).images[0].save("output.png")
¶ 2-Step, 4-Step, 8-Step LoRA
If you’re using non-SDXL base models, LoRA weights can enhance image generation:
import torch
from diffusers import StableDiffusionXLPipeline, EulerDiscreteScheduler
from huggingface_hub import hf_hub_download
base = "stabilityai/stable-diffusion-xl-base-1.0"
repo = "ByteDance/SDXL-Lightning"
ckpt = "sdxl_lightning_4step_lora.safetensors"
# Load model.
pipe = StableDiffusionXLPipeline.from_pretrained(base, torch_dtype=torch.float16, variant="fp16").to("cuda")
pipe.load_lora_weights(hf_hub_download(repo, ckpt))
pipe.fuse_lora()
# Set scheduler and steps.
pipe.scheduler = EulerDiscreteScheduler.from_config(pipe.scheduler.config, timestep_spacing="trailing")
pipe("A girl smiling", num_inference_steps=4, guidance_scale=0).images[0].save("output.png")
¶ 1-Step UNet
The experimental 1-step model prioritizes speed but requires careful configuration. It uses "sample" prediction instead of "epsilon" prediction.
import torch
from diffusers import StableDiffusionXLPipeline, UNet2DConditionModel, EulerDiscreteScheduler
from huggingface_hub import hf_hub_download
from safetensors.torch import load_file
base = "stabilityai/stable-diffusion-xl-base-1.0"
repo = "ByteDance/SDXL-Lightning"
ckpt = "sdxl_lightning_1step_unet_x0.safetensors"
# Load model.
unet = UNet2DConditionModel.from_config(base, subfolder="unet").to("cuda", torch.float16)
unet.load_state_dict(load_file(hf_hub_download(repo, ckpt), device="cuda"))
pipe = StableDiffusionXLPipeline.from_pretrained(base, unet=unet, torch_dtype=torch.float16, variant="fp16").to("cuda")
# Configure scheduler for "sample" prediction type.
pipe.scheduler = EulerDiscreteScheduler.from_config(pipe.scheduler.config, timestep_spacing="trailing", prediction_type="sample")
pipe("A girl smiling", num_inference_steps=1, guidance_scale=0).images[0].save("output.png")
¶ ComfyUI Usage
ComfyUI provides a visual, node-based interface for SDXL Lightning, making it an excellent choice for both beginners and advanced users. Always match the checkpoint with the corresponding inference steps and use the Euler sampler with the sgm_uniform scheduler.
