This is a workflow example to work with SDXL.

With this workflow you will be able to upscale from 768x768 to 4669x4669. It includes full resolution inpaint section using SDXL models workflow based on inpaint at full resolution.

It also includes batch processing mode, just connect the "Load image list from dir" node or for single image the "Load image" node.

• You can use any SDXL model by default it uses the jibMixIllustrious_v20Revelation.safetensors model

• Download sdxl_lightning_4step_lora.safetensors and place in loras

• For ControlNet you can use diffusion_pytorch_model_promax.safetensors and ttplanetSDXLControlnet_v20Fp16.safetensors

• The upscalers using as defaults are 4x-UltraSharp.pth, 8x_NMKD-Superscale_150000_G.pth, 4x_UniversalUpscalerV2-Sharp_101000_G.pth

To use just import the .json file in comfyui and install the missing nodes under manager -> install missing custom nodes. This workflow was tested to work on MacBook pro M2. but it should also work on linux and windows systems.
