It is now possible to generate 16 Megapixel (4096x4096) raw images with SANA 4K model using under 8GB VRAM, 4 Megapixel (2048x2048) images using under 6GB VRAM, and 1 Megapixel (1024x1024) images using under 4GB VRAM thanks to new optimizations (Patreon)

Now the APP will use Diffusers Pipeline and it has huge VRAM optimizations

You need to reinstall

The models will be downloaded into your Hugging Face cache folder when you first time generate something

How to Get Installation Logs and How to Change Hugging Face Cache Folder

Please make a fresh install

When you enable all 4 optimizations the VRAM usages are like below

Make sure shared VRAM is enabled because initial loading of the model need more VRAM

Enable VAE Tiling + Enable VAE Slicing + Enable Model CPU Offload +

Enable Sequential CPU Offload

1K (1024x1024) : 4 GB GPUs

2K (2048x2048) : 6 GB GPUs

4K (4096x4096) : 8 GB GPUs

Still in any case may work on your GPU test it

Just Enable VAE Tiling + Enable Model CPU Offload works great in many cases
