ControlNet-Union SDXL ProMax

An all-in-one open-source control framework developed by researcher Xinsir to streamline conditional image generation for Stable Diffusion XL. Historically, digital artists had to download individual multi-gigabyte files for every control technique, like Canny edges, openpose, depth maps, or scribbles. This ProMax model eliminates that fragmentation by unifying over 12 distinct spatial conditions and 5 advanced editing controls into a single, compact checkpoint. It allows creators to mix multiple physical inputs - such as a specific hand pose and a geometric room wireframe - simultaneously within a single generation step. This massive architectural reduction eliminates software overhead, making multi-condition workflows incredibly fast and resource-efficient inside ComfyUI or Automatic1111.
