 - `face`\
 	Automatically sets the focal point based on detected faces in an image. This can be combined with the `zoom` parameter to specify how closely the image should be cropped towards the faces.
+
 	The new focal point is determined by a minimum bounding box that surrounds all detected faces. If no faces are found, then the focal point will fall back to the center of the image.
 
+	This feature uses an open-source model called RetinaFace through WorkersAI. Our model pipeline is limited only to facial detection, or identifying the pixels that represent a human face. We do not suppoert facial identification or recognition. Read more about Cloudflare's [approach to responsible AI](https://www.cloudflare.com/trust-hub/responsible-ai/).
