Stable Diffusion
Upsampler's custom Stable Diffusion-powered upscaler. Preserves the overall composition while regenerating fine detail — good for upscaling that should keep the source recognizable while filling in plausible texture and detail. A different aesthetic from the Flux upscaler; pick whichever style fits the source. Only available on Upsampler.
