成本僅爲十分之一！Open-Sora 2.0 開源視頻 AI 實現商業級畫質
近日，HPC-AI Tech 宣佈推出 Open-Sora2.0，這是一款突破性的視頻 AI 系統，僅需約十分之一的典型訓練成本即可實現商業級質量。這一進展標誌着在資源密集型的視頻 AI 領域可能出現範式轉變，堪比語言模型中出現的效率提升。雖然像 Movie Gen 和 Step-Video-T2V 這樣現有的高質量視頻生成系統可能需要數百萬美元的訓練費用，但 Open-Sora2.0的訓練支出僅約爲20萬美元。儘管成本大幅降低，但測試表明，其輸出質量可與 Runway Gen-3Alpha 和 HunyuanVideo 等已建立的商業系統相媲美。該系統使用了224個 Nvidia H20
