# SD-XL 1.0-base Model Card - Neuron |
|
 |
|
|
|
## Model |
|
|
|
 |
|
|
|
[SDXL](https://arxiv.org/abs/2307.01952) consists of an [ensemble of experts](https://arxiv.org/abs/2211.01324) pipeline for latent diffusion: |
|
In a first step, the base model is used to generate (noisy) latents, |
|
which are then further processed with a refinement model (available here: https://huggingface.co/stabilityai/stable-diffusion-xl-refiner-1.0/) specialized for the final denoising steps. |
|
Note that the base model can be used as a standalone module. |
|
|
|
Alternatively, we can use a two-stage pipeline as follows: |
|
First, the base model is used to generate latents of the desired output size. |
|
In the second step, we use a specialized high-resolution model and apply a technique called SDEdit (https://arxiv.org/abs/2108.01073, also known as "img2img") |
|
to the latents generated in the first step, using the same prompt. This technique is slightly slower than the first one, as it requires more function evaluations. |

### Model Description |
|
|
|
- **Developed by:** Stability AI |
|
- **Model type:** Diffusion-based text-to-image generative model |
|
- **License:** [CreativeML Open RAIL++-M License](https://huggingface.co/stabilityai/stable-diffusion-xl-base-1.0/blob/main/LICENSE.md) |
|
- **Model Description:** This is a model that can be used to generate and modify images based on text prompts. It is a [Latent Diffusion Model](https://arxiv.org/abs/2112.10752) that uses two fixed, pretrained text encoders ([OpenCLIP-ViT/G](https://github.com/mlfoundations/open_clip) and [CLIP-ViT/L](https://github.com/openai/CLIP/tree/main)). |
|
- **Resources for more information:** Check out our [GitHub Repository](https://github.com/Stability-AI/generative-models) and the [SDXL report on arXiv](https://arxiv.org/abs/2307.01952). |

|
### Model Sources |
|
|
|
For research purposes, we recommend our `generative-models` Github repository (https://github.com/Stability-AI/generative-models), which implements the most popular diffusion frameworks (both training and inference) and for which new functionalities like distillation will be added over time. |
|
[Clipdrop](https://clipdrop.co/stable-diffusion) provides free SDXL inference. |

## Evaluation |
|
 |
|
The chart above evaluates user preference for SDXL (with and without refinement) over SDXL 0.9 and Stable Diffusion 1.5 and 2.1. |
|
The SDXL base model performs significantly better than the previous variants, and the model combined with the refinement module achieves the best overall performance. |
|
|
|
|
|
### Usage |
|
|
|
```py |
|
from diffusers import DPMSolverMultistepScheduler |
|
from optimum.neuron import NeuronStableDiffusionXLPipeline |
|
|
|
pipeline = NeuronStableDiffusionXLPipeline.from_pretrained("Shekswess/stable-diffusion-xl-base-1.0-neuron", device_ids=[0, 1]) |
|
pipeline.scheduler = DPMSolverMultistepScheduler.from_config(pipeline.scheduler.config) |
|
|
|
prompt = "A swirling beautiful exploding scene of magical wonders and surreal ideas and objects with portraits of beautiful woman with silk back to camera, flowers, light, cosmic wonder, nebula, high-resolution" |
|
image = pipeline(prompt=prompt).images[0].save("output.png) |
|
``` |
|
|

## Uses |
|
|
|
### Direct Use |
|
|
|
The model is intended for research purposes only. Possible research areas and tasks include |
|
|
|
- Generation of artworks and use in design and other artistic processes. |
|
- Applications in educational or creative tools. |
|
- Research on generative models. |
|
- Safe deployment of models which have the potential to generate harmful content. |
|
- Probing and understanding the limitations and biases of generative models. |
|
|
|
Excluded uses are described below. |
|
|
|
### Out-of-Scope Use |
|
|
|
The model was not trained to be factual or true representations of people or events, and therefore using the model to generate such content is out-of-scope for the abilities of this model. |
|
|
|
## Limitations and Bias |
|
|
|
### Limitations |
|
|
|
- The model does not achieve perfect photorealism |
|
- The model cannot render legible text |
|
- The model struggles with more difficult tasks which involve compositionality, such as rendering an image corresponding to “A red cube on top of a blue sphere” |
|
- Faces and people in general may not be generated properly. |
|
- The autoencoding part of the model is lossy. |
|
|
|
### Bias |
|
While the capabilities of image generation models are impressive, they can also reinforce or exacerbate social biases. |
