Section 1
One step, real-time feel
SDXL Turbo uses adversarial diffusion distillation to collapse generation to a single step. On a decent GPU, it renders 512x512 images at 10+ FPS — fast enough that users see the image update as they type.
Section 2
What you can build
- Live prompt sandbox with instant preview
- Drawing tools where the model reimagines your strokes as you draw
- Classroom demos that show how prompts change output in real time
- Mood-board generation in Figma-like speed
Compare the options
| Model | Steps | GPU latency (512) | Quality |
|---|---|---|---|
| SDXL Turbo | 1 | <100ms on H100 | Good for size |
| SDXL base | 30-50 | 2-5s | Great |
| Flux Schnell | 1-4 | 1-2s | Better than Turbo |
| Flux Pro | 20-50 | 3-6s (API) | Best |
Design tradeoffs
- Turbo trades top-end quality for speed — do not expect print-ready output
- Text and hands still struggle
- Works best at 512 or 768 resolution; higher sizes lose the speed advantage
- Pair with a second-pass refiner for finals
One step, zero guidance scale. That is the Turbo recipe.
from diffusers import AutoPipelineForText2Image
import torch
pipe = AutoPipelineForText2Image.from_pretrained(
"stabilityai/sdxl-turbo", torch_dtype=torch.float16
).to("cuda")
img = pipe(prompt="a fox in a meadow", num_inference_steps=1, guidance_scale=0.0).images[0]Section 3
A two-pass pattern
Show Turbo live while the user iterates. When they commit to a prompt, render the final with SDXL base or Flux Pro for print-quality output. Best of both worlds — real-time feel, publish-grade finals.
