Upscaling In SwarmUI

Upscale Stages

There are two places to upscale, differing in what happens after:

Refine / Upscale group: the refiner model samples over the upscaled result, per Refiner Control Percentage. Set that to 0 for an upscale-only stage.
Final Stage group: runs after the base and refiner stages are done, and nothing samples over the result, only whatever the upscaler does itself.
- Final Upscale stacks on top of Refiner Upscale, eg 1.5 refiner upscale and 2 final upscale is 3x total.
- Final Upscale Method offers the same methods as Refiner Upscale Method, minus the latent upscalers (which need a sampler after them).

SeedVR2 is a one-step restoration model for upscaling images or videos.
- Models can be downloaded here: Comfy-Org/SeedVR2
- Save in diffusion_models
- The VAE will be automatically downloaded
Select it as your Refiner Upscale Method or your Final Upscale Method, see Upscale Stages
