tails-models unavailable

Hi, I'm trying to download the pre-trained model from gs://tails-models, but the bucket is unavailable (error: "Entire service unavailable since Aug 22, 2025"). 

Could you please provide an alternative download link (e.g., GitHub Releases, Zenodo, Baidu Netdisk) for the tails-20210107 model? It's needed to run the example script. Thanks!
