+
+We introduce **Sana**, a text-to-image framework that can efficiently generate images up to 4096 × 4096 resolution.
+Sana can synthesize high-resolution, high-quality images with strong text-image alignment at a remarkably fast speed, deployable on laptop GPU.
+
+Source code is available at https://github.com/NVlabs/Sana.
+
+### Model Description
+
+- **Developed by:** NVIDIA, Sana
+- **Model type:** Linear-Diffusion-Transformer-based text-to-image generative model
+- **Model size:** 1648M parameters
+- **Model precision:** torch.bfloat16 (BF16)
+- **Model resolution:** This model is developed to generate 1024px based images with multi-scale heigh and width.
+- **License:** [CC BY-NC-SA 4.0 License](./LICENSE.txt)
+- **Model Description:** This is a model that can be used to generate and modify images based on text prompts. 
+It is a Linear Diffusion Transformer that uses one fixed, pretrained text encoders ([Gemma2-2B-IT](https://huggingface.co/google/gemma-2-2b-it))
+and one 32x spatial-compressed latent feature encoder ([DC-AE](https://hanlab.mit.edu/projects/dc-ae)).
+- **Resources for more information:** Check out our [GitHub Repository](https://github.com/NVlabs/Sana) and the [Sana report on arXiv](https://arxiv.org/abs/2410.10629).
+
+### Model Sources
+
+For research purposes, we recommend our `generative-models` Github repository (https://github.com/NVlabs/Sana), 
+which is more suitable for both training and inference and for which most advanced diffusion sampler like Flow-DPM-Solver is integrated.
+[MIT Han-Lab](https://nv-sana.mit.edu/) provides free Sana inference.

+### 🧨 Diffusers 
+
+PR developing: [Sana](https://github.com/huggingface/diffusers/pull/9982) and [DC-AE](https://github.com/huggingface/diffusers/pull/9708)
+
+
+## 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 complex legible text
+- fingers, .etc 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.
