AI-generated commentary
AI-generated explanation based on source and configuration details. Suggestions are clearly labeled.
Purpose
FLUX.1 SmartUpscaler-[2Pass Upscaler]. ControlNet + SD UPscale is for restoring, upscaling, and color-fixing low-resolution realistic images and portraits. It takes a loaded image and can optionally use a prompt, then can output images at 4 megapixels or more.
Flow
By default, the loaded image—including a 256x256 image—is resized to 1 megapixel, then upscaled according to the value set in Ultimate SD Upscale.
Inputs and outputs
A prompt is optional; the description says it may help with unstable results, along with denoise values.
Suggestion · not verified
Set Image Upscale_by = 1 when you want the upscaler to act as an image refiner.
Suggestion · not verified
Setup
It uses Flux.1 D as its base model and is published by Nxssar.
Dependencies
Named model files include 4x_NMKD-Siax_200k.pth, clip_l.safetensors, Flux.1-dev-Controlnet-Upscaler.safetensors, flux1-dev-Q6_K.gguf, t5xxl_fp8_e4m3fn.safetensors, and thwri/CogFlorence-2.2-Large.
