ControlNet Auxiliary Models

ControlNet Auxiliary Models (controlnet-aux) provides a PyPI installable package of lllyasviel's ControlNet Annotators. It offers various preprocessors (e.g., Canny, OpenPose, Midas) for generating hint images like edges, depth maps, and poses, which are used to guide image generation with ControlNet models. The library is currently at version 0.0.10, released on May 8, 2025, with an irregular release cadence primarily driven by upstream ControlNet updates.
