Desired output resolution for upscaling with `upscale_mode` set to `target`.

default 2

Multiplier applied to the dimensions when `upscale_mode` is set to `factor`.

Advanced output_format · noise_scale · seed

About SeedVR2 · Image

Upscales a single image from `image_url`. In factor mode `upscale_factor` multiplies dimensions by 1 to 10. In target mode `target_resolution` can be 720p, 1080p, 1440p or 2160p. `noise_scale` (0 to 1) and `seed` adjust the result, and `output_format` is jpg by default, with png and webp also allowed.
