DemoFusion

Use this sub-skill for the extension's separate DemoFusion panel. DemoFusion performs staged multi-scale denoising/upscaling with local tiled windows and global views. It is not the same route as the Tiled Diffusion panel.

When to read

Read this when the user asks about:

• enabling DemoFusion in AUTOMATIC1111;
• staged x2/x3/x4 upscale behavior;
• latent window size, overlap, local/global batch sizes;
• random jitter, mixture mode, Gaussian filter, cosine scales, or sigma;
• DemoFusion with img2img, keep-input-size, or noise inversion;
• why the panel says not to open DemoFusion with Tiled Diffusion;
• DemoFusion UniPC incompatibility, speed, OOM, or image-size infotext behavior.

For normal Tiled Diffusion/MultiDiffusion/Mixture of Diffusers, route to tiled-diffusion. For VAE encode/decode OOM, route to tiled-vae.

Core operating facts

• The panel title is DemoFusion.
• The UI text warns: do not open DemoFusion with Tiled Diffusion.
• The only method choice is DemoFusion.
• DemoFusion asserts that it is not compatible with UniPC.
• Scale factor is used as an integer staged upscale count.
• Window size defaults to 128 and is bounded by the latent canvas size.
• Window overlap defaults to 64.
• Local tile batch size and global window batch size both default to 4.
• Random jitter defaults on.
• Cosine scale defaults are 3, 1, and 1; sigma defaults to 0.6.
• Txt2img exposes denoising strength for the substage with default 0.85.
