However, achieving efficient generation and high-fidelity long-form audio while supporting controllability remains challenging. To address these needs, we present WanSong, a simple yet powerful approach for long-form, commercial-grade song generation. Unlike autoregressive (AR) and cascaded multi-stage pipelines (\\eg, AR followed by diffusion), WanSong is a pure diffusion-based model that directly generates high-fidelity, multilingual songs up to 5 minutes and outputs dual stems (vocals and background music) in a single run. In addition, our diffusion framework enables faster inference through step-distillation, and offers an efficient pathway for fine-tuning and customization to support downstream editing tasks.","upvotes":8,"discussionId":"6a59954d6c2e371e6ca380e4","organization":{"_id":"67bc7cd418dd753c02a82684","name":"Wan-AI","fullname":"Wan-AI","avatar":"https://cdn-avatars.huggingface.co/v1/production/uploads/67b610677ea7952def8b29c6/N6jQbbeaa_FcUY-wI1dgG.png"}},"canReadDatabase":false,"canManagePapers":false,"canSubmit":false,"hasHfLevelAccess":false,"upvoted":false,"upvoters":[{"_id":"6270324ebecab9e2dcf245de","avatarUrl":"https://cdn-avatars.huggingface.co/v1/production/uploads/6270324ebecab9e2dcf245de/cMbtWSasyNlYc9hvsEEzt.jpeg","isPro":false,"fullname":"Kye Gomez","user":"kye","type":"user"},{"_id":"620783f24e28382272337ba4","avatarUrl":"https://cdn-avatars.huggingface.co/v1/production/uploads/620783f24e28382272337ba4/zkUveQPNiDfYjgGhuFErj.jpeg","isPro":false,"fullname":"GuoLiangTang","user":"Tommy930","type":"user"},{"_id":"67bbade8a8c89b98ec377944","avatarUrl":"https://cdn-avatars.huggingface.co/v1/production/uploads/67bbade8a8c89b98ec377944/HPtKDo8fnKr4OxpN1Z17D.png","isPro":false,"fullname":"Urodoc Oncall","user":"UDCAI","type":"user"},{"_id":"66d2e8d41ba71ac4c08e0307","avatarUrl":"/avatars/4cfc4b11d66739d072f7166bb9d43f08.svg","isPro":false,"fullname":"SR.Suzume","user":"srsuzume","type":"user"},{"_id":"65c4eb7cd1dcbd30d86febec","avatarUrl":"/avatars/001c8f02e8ce794b2c21883628b2da72.svg","isPro":false,"fullname":"free-bit","user":"free-bit","type":"user"},{"_id":"69bd4f7b22b6ccba8310e4aa","avatarUrl":"https://cdn-avatars.huggingface.co/v1/production/uploads/noauth/YFn0ccaFDkkhr4tXJQ6BH.jpeg","isPro":false,"fullname":"佐藤蒼","user":"victoriajohnson","type":"user"},{"_id":"6a2da6c8ca070ee12c6e396c","avatarUrl":"/avatars/0355287dcabaa67dbc7f0b10b87451f9.svg","isPro":false,"fullname":"Joe Mama","user":"JoeMama123123123","type":"user"},{"_id":"69ccf171be44414ace4df2db","avatarUrl":"https://cdn-avatars.huggingface.co/v1/production/uploads/noauth/tfSoQatYvAMQMu_sHVc1A.png","isPro":false,"fullname":"이민서","user":"jacksonmartin51","type":"user"}],"acceptLanguages":["en"],"dailyPaperRank":0,"organization":{"_id":"67bc7cd418dd753c02a82684","name":"Wan-AI","fullname":"Wan-AI","avatar":"https://cdn-avatars.huggingface.co/v1/production/uploads/67b610677ea7952def8b29c6/N6jQbbeaa_FcUY-wI1dgG.png"},"markdownContentUrl":"https://huggingface.co/buckets/huggingchat/papers-content/resolve/2607/2607.14749.md","query":{}}">
