Model Card

SDXL ControlNet LoRA is an image generation model built by FermatResearch that adds canny-edge ControlNet conditioning and LoRA support on top of Stability AI's SDXL.

The canny ControlNet extracts an edge map from a reference image and uses it to guide generation, so the output follows the structure of that input. LoRA weights are then applied on top, so a custom style or subject can be layered onto that same structure in a single request, instead of running separate structure and style passes.

The project is open source (published on GitHub as a Cog implementation) and also supports img2img for iterative refinement. It suits developers who need both structural control, such as matching a pose or layout, and a custom visual style from a trained LoRA, in one API call.
