What is Sana?
Sana is a text-to-image framework developed by NVIDIA that efficiently generates high-resolution images up to 4096x4096 pixels. It quickly synthesizes high-quality images while maintaining strong alignment between text and visuals, and can be deployed on laptop GPUs. Based on linear diffusion transformers, it uses pre-trained text encoders and spatially compressed latent feature encoders, supporting emojis, Chinese, English, and mixed prompts.
Who Can Use Sana?
Sana is ideal for researchers, designers, artists, and educators. Researchers can use it to explore and improve image generation models. Designers and artists can generate high-quality images for art and design projects. Educators can utilize it as a teaching tool to help students understand image generation technology.
Example Scenarios
Generate an image of a tiger playing the saxophone in a T-shirt.
Create an image of a cat wearing sunglasses flying over a rainbow with a rose in its hand using mixed language prompts.
Produce an image of the Great Wall at sunset in traditional Chinese style.
