 This model is an approximate version of [IMATAG](https://www.imatag.com/)'s BZH decoder for the watermark embedded in our [SDXL-turbo watermarking demo](https://huggingface.co/spaces/imatag/stable-signature-bzh).
 It works on this watermark only and cannot be used to decode other watermarks.
-It will produce an approximate p-value measuring the risk of mistakenly detecting a watermark an a benign (non-watermarked) image. For an exact p-value and improved robustness, please use the [API](https://huggingface.co/spaces/imatag/stable-signature-bzh/resolve/main/detect_api.py) instead.
