⚡ Modern Diffusion Models

🌟 Stable Diffusion 3.5 (2024)

SD 3.5 Hugging Face

Revolutionary Features:

  • 🎯 Multimodal Diffusion Transformer (MMDiT)
  • 📝 Superior text rendering capabilities
  • 🎨 Enhanced prompt understanding with T5-XXL
  • ⚡ Efficient inference with flow matching
  • 🔧 Better fine-tuning capabilities

Implementation:

import torch
from diffusers import StableDiffusion3Pipeline

# Load SD 3.5 model
pipe = StableDiffusion3Pipeline.from_pretrained(
    "stabilityai/stable-diffusion-3.5-large",
    torch_dtype=torch.float16,
    variant="fp16"
)
pipe.to("cuda")

# Enable optimizations
pipe.enable_model_cpu_offload()
pipe.enable_vae_slicing()

# Generate with advanced prompting
prompt = """
A hyperrealistic photograph of a futuristic cityscape at sunset,
neon lights reflecting on wet streets, flying cars,
cyberpunk aesthetic, 8k ultra detailed, professional photography
"""

negative_prompt = "blurry, low quality, distorted, deformed"

image = pipe(
    prompt=prompt,
    negative_prompt=negative_prompt,

    guidance_scale=7.0,
    height=1024,
    width=1024,
).images[0]

image.save("sd35_output.png")

Performance Optimization:

# Use SDXL Turbo scheduler for faster generation
from diffusers import LCMScheduler

pipe.scheduler = LCMScheduler.from_config(pipe.scheduler.config)

# 4-step generation with quality
image = pipe(
    prompt=prompt,

🎯 Quick Start Guide

Beginners: Start Here

# Install dependencies
# pip install diffusers transformers accelerate torch

import torch
from diffusers import StableDiffusion3Pipeline

# Load model (auto-downloads)
pipe = StableDiffusion3Pipeline.from_pretrained(
    "stabilityai/stable-diffusion-3.5-large",
    torch_dtype=torch.float16
)
pipe.to("cuda")

# Generate your first image
image = pipe("a majestic lion in the savanna, golden hour").images[0]
image.save("my_first_generation.png")

Intermediate: Optimize Performance

# Enable all optimizations
pipe.enable_model_cpu_offload()
pipe.enable_vae_slicing()
pipe.enable_vae_tiling()

# Use flash attention if available
try:
    pipe.enable_xformers_memory_efficient_attention()
except:
    pass

# Compile for 40% speedup (PyTorch 2.0+)
pipe.unet = torch.compile(pipe.unet, mode="reduce-overhead", fullgraph=True)

Advanced: Production Setup

# Multi-GPU inference
pipe = StableDiffusion3Pipeline.from_pretrained(
    "stabilityai/stable-diffusion-3.5-large",
    torch_dtype=torch.float16,
    variant="fp16",
    device_map="balanced"  # Auto-distribute across GPUs
)

# Batch generation
prompts = ["prompt1", "prompt2", "prompt3", "prompt4"]
images = pipe(prompts, num_inference_steps=28).images
