Inputs (6)

NameTypeDefaultDescription
latentLATENTLatent to upscale and re-noise before sampling.
seedINT00–18446744073709550000Seed controlling flow re-noise (use as Custom Sampler noise seed for determinism).
scale_factorFLOAT1.000.1–8Spatial scale factor applied to the latent grid for this stage.
noise_ratioFLOAT0.000–1Flow-style re-noise amount (0 = keep latent, 1 = replace with pure noise).
upscale_methodCOMBObicubicResampling kernel for spatial upscaling. NOTE: ComfyUI's `lanczos` path uses PIL and is unsafe for LATENT tensors; this node will fall back to `bicubic` if selected.
reduce_memory_useoptCOMBOenableEnable to reduce VRAM use by avoiding extra tensor clones where possible.
