Download and Install Stable Diffusion 3 Medium
Step 1: Install the Required Packages
Run the following command to install the necessary packages:
pip install torch diffusersStep 2: Download the Model
Use the following code to download the model files from Hugging Face:
import torch
from diffusers import StableDiffusion3Pipeline
pipe = StableDiffusion3Pipeline.from_pretrained("stabilityai/stable-diffusion-3-medium-diffusers", torch_dtype=torch.float16)
pipe.to("cuda")
How to Use Stable Diffusion 3 Medium?
Text-to-Image Generation
Generate an image using the following command:
prompt = "A cat holding a sign that says hello world"
image = pipe(prompt, num_inference_steps=28, guidance_scale=7.0).images[0]
image.save("sd3_hello_world.png")
Image-to-Image Generation
Use the image-to-image functionality with the following code:
from diffusers import StableDiffusion3Img2ImgPipeline
from PIL import Image
init_image = Image.open("path/to/initial/image.png")
pipe = StableDiffusion3Img2ImgPipeline.from_pretrained("stabilityai/stable-diffusion-3-medium-diffusers", torch_dtype=torch.float16)
pipe.to("cuda")
prompt = "A cat wizard, detailed, fantasy, 8k"
image = pipe(prompt=prompt, image=init_image).images[0]
image.save("wizard_cat.png")
Additional Tips for Stable Diffusion 3 Medium
Optimizing Performance
- Use a lower CFG scale (4-6) for more refined images.
- Consider model offloading to manage memory efficiently on GPUs with less than 24GB VRAM.
Memory Management
Use the following code to enable model offloading:
pipe.enable_model_cpu_offload()
image = pipe(prompt="A detailed painting of a castle", num_inference_steps=50).images[0]
image.save("castle.png")
Stable Diffusion 3 Medium is designed to be a robust and flexible model suitable for a wide range of applications. Whether you need advanced image generation, efficient resource usage, or safe and responsible AI, this model provides a comprehensive solution. By following the installation and usage guidelines, you can harness the full potential of Stable Diffusion 3 Medium for your projects.
