字節跳動發佈 Seedance 2.5 視頻生成模型，單次生成時長翻倍至 30 秒，將陸續上線即夢 AI、豆包專業版，API 接入火山方舟，覆蓋影視、廣告、教育、工業製造及自動駕駛等場景。該模型延續多模態音視頻聯合生成架構，重點提升長敘事、多模態參考與編輯能力，推動 AI 視頻從短片段邁向長內容創作。
字節跳動發佈音頻創作模型Seed Audio1.0，已在火山方舟開放測試。它打破傳統影視音頻需多模型分別生成人聲、音效與環境聲再人工拼接的冗長流程，實現聲音場景一體化創作，確保敘事一致性，標誌着AI音頻生成進入完整聲音場景新階段。
2026年6月23日，火山引擎在夏季FORCE原動力大會上發佈豆包視頻生成模型Seedance2.5，計劃7月上線。該模型實現30秒單段原生視頻直出、50個全模態素材聯合生成及保持畫面一致性的局部編輯三大突破。總裁譚待表示，視頻生成是通往世界模型的關鍵。
字節跳動火山引擎旗下火山方舟體驗中心上線Seedance 2.0 Mini視頻生成模型，主打高性價比，近期將開放API服務。該輕量化版本在保持高質量輸出的同時，生成速度比同系列標準快速版更快，旨在服務更廣泛的視頻創作與規模化生產市場。
