Sana was released in January 2025 and is jointly led by NVIDIA, MIT, and Tsinghua University. Sana is a text-to-image framework that can effectively generate images with a resolution of up to 4096 × 4096. Sana can synthesize high-resolution, high-quality images at a very fast speed and has strong text-image alignment capabilities.SANA: Efficient High-Resolution Image Synthesis with Linear Diffusion Transformers", has been accepted by ICLR 2025.
This tutorial uses the Sana_1600M_1024px model for demonstration, and the computing power resource uses a single card 4090.
