SeedVR2 image upscale
Create an enlarged, restored image with SeedVR2 and optional source color matching. Upload the image to restore, leave Scale factor at 4 and Color matching at none, then run. The default multiplies both dimensions by 4, producing approximately 16 times the source pixel count before restoration. No text prompt is required: the uploaded image supplies conditioning. The model is fixed to SeedVR2 3B int8 with its matching VAE.
