![image/png](https://cdn-uploads.huggingface.co/production/uploads/62039c2d91d53938a643317d/0Iu_0f0d1ihGy0YiOd9uS.png)


## Model Description

The Segmind Stable Diffusion Model (SSD-1B) is a **distilled 50% smaller** version of the Stable Diffusion XL (SDXL), offering a **60% speedup** while maintaining high-quality text-to-image generation capabilities. It has been trained on diverse datasets, including Grit and Midjourney scrape data, to enhance its ability to create a wide range of visual content based on textual prompts.

This model employs a knowledge distillation strategy, where it leverages the teachings of several expert models in succession, including SDXL, ZavyChromaXL, and JuggernautXL, to combine their strengths and produce impressive visual outputs.

Special thanks to the HF team 🤗 especially [Sayak](https://huggingface.co/sayakpaul), [Patrick](https://github.com/patrickvonplaten) and [Poli](https://huggingface.co/multimodalart) for their collaboration and guidance on this work.

## Usage:
This model can be used via the 🧨 Diffusers library. 

Make sure to install diffusers from source by running
```
pip install git+https://github.com/huggingface/diffusers
```

In addition, please install `transformers`, `safetensors` and `accelerate`:
```
pip install transformers accelerate safetensors
```

To use the model, you can run the following:

```py
from diffusers import StableDiffusionXLPipeline
import torch
pipe = StableDiffusionXLPipeline.from_pretrained("segmind/SSD-1B", torch_dtype=torch.float16, use_safetensors=True, variant="fp16")
pipe.to("cuda")
# if using torch < 2.0
# pipe.enable_xformers_memory_efficient_attention()
prompt = "An astronaut riding a green horse" # Your prompt here
neg_prompt = "ugly, blurry, poor quality" # Negative prompt here
image = pipe(prompt=prompt, negative_prompt=neg_prompt).images[0]
```

## Uses


### Direct Use

The Segmind Stable Diffusion Model is suitable for research and practical applications in various domains, including:

- **Art and Design:** It can be used to generate artworks, designs, and other creative content, providing inspiration and enhancing the creative process.

- **Education:** The model can be applied in educational tools to create visual content for teaching and learning purposes.

- **Research:** Researchers can use the model to explore generative models, evaluate its performance, and push the boundaries of text-to-image generation.

- **Safe Content Generation:** It offers a safe and controlled way to generate content, reducing the risk of harmful or inappropriate outputs.

- **Bias and Limitation Analysis:** Researchers and developers can use the model to probe its limitations and biases, contributing to a better understanding of generative models' behavior.

### Downstream Use

The Segmind Stable Diffusion Model can also be used directly with the 🧨 Diffusers library training scripts for further training, including:

- **[Fine-Tune](https://github.com/huggingface/diffusers/blob/main/examples/text_to_image/train_text_to_image_sdxl.py)**
- **[LoRA](https://github.com/huggingface/diffusers/blob/main/examples/text_to_image/train_text_to_image_lora_sdxl.py)**
- **[Dreambooth LoRA](https://github.com/huggingface/diffusers/blob/main/examples/dreambooth/train_dreambooth_lora_sdxl.py)**

### Out-of-Scope Use

The SSD-1B Model is not suitable for creating factual or accurate representations of people, events, or real-world information. It is not intended for tasks requiring high precision and accuracy.

## Limitations and Bias

### Limitations

- **Photorealism:** The model does not achieve perfect photorealism and may produce images with artistic or stylized qualities.

- **Legible Text:** Generating legible text within images is a challenge for the model, and text within images may appear distorted or unreadable.

- **Compositionality:** Complex tasks involving composition, such as rendering images based on intricate descriptions, may pose challenges for the model.

- **Faces and People:** While the model can generate a wide range of content, it may not consistently produce realistic or high-quality images of faces and people.

- **Lossy Autoencoding:** The autoencoding aspect of the model is lossy, which means that some details in the input text may not be perfectly retained in the generated images.

### Bias

The SSD-1B Model is trained on a diverse dataset, but like all generative models, it may exhibit biases present in the training data. Users are encouraged to be mindful of potential biases in the model's outputs and take appropriate steps to mitigate them.
