What is 4x UltraSharp?
4x UltraSharp is an upscale model that increases image resolution while preserving or enhancing detail. You can run it locally in ComfyUI with full control over every parameter, or access it through Comfy Cloud. ComfyUI's node-based workflow editor lets you connect 4x UltraSharp with ControlNets, LoRAs, upscalers, and custom nodes to build any pipeline you need. There are 2 community workflow templates using 4x UltraSharp on Comfy Hub, ready to load and customize.
