# stable-diffusion-3.5-large-turbo

ADD-distilled Multimodal Diffusion Transformer (MMDiT) text-to-image model. Uses three fixed, pretrained text encoders with QK-normalization. Designed for high-quality output at low step counts (typically 4 steps, guidance 0.0).

This repository is an unmodified redistribution of [`stabilityai/stable-diffusion-3.5-large-turbo`](https://huggingface.co/stabilityai/stable-diffusion-3.5-large-turbo). Weights, configs, and license are preserved verbatim.

## Inference

```python
import torch
from diffusers import StableDiffusion3Pipeline

pipe = StableDiffusion3Pipeline.from_pretrained(
    "cudabenchmarktest/stable-diffusion-3.5-large-turbo",
    torch_dtype=torch.bfloat16,
).to("cuda")

image = pipe(
    "A capybara holding a sign that reads Hello Fast World",
