Inputs (8)

NameTypeDefaultDescription
latent*Input latent (image or video).
model_nameCOMBOMinimax H3 upscale model.
modeCOMBOHow the target size is computed.
alignINT321–512Pixel-space alignment. Both output axes are placed on a grid compatible with this value and the H3 16x VAE grid.
keep_proportionBOOLEANtruePreserve the source aspect ratio as closely as the requested alignment grid allows.
deviceCOMBOcuda2 options: cuda, cpu
precisionCOMBOfp163 options: fp32, fp16, bf16
offload_after_upscaleBOOLEANfalseMove the cached learned upscaler to CPU after inference to free VRAM. Leave off for faster repeated runs when VRAM is available.
