The extension helps you to **generate or upscale large images (≥2K) with limited VRAM (≤6GB)** via the following techniques:

- Reproduced SOTA Tiled Diffusion methods
  - [Mixture of Diffusers](https://github.com/albarji/mixture-of-diffusers)
  - [MultiDiffusion](https://multidiffusion.github.io)
  - [Demofusion](https://github.com/PRIS-CV/DemoFusion)
- Our original Tiled VAE method
- My original Tiled Noise Inversion method
