成本仅为十分之一！Open-Sora 2.0 开源视频 AI 实现商业级画质
近日，HPC-AI Tech 宣布推出 Open-Sora2.0，这是一款突破性的视频 AI 系统，仅需约十分之一的典型训练成本即可实现商业级质量。这一进展标志着在资源密集型的视频 AI 领域可能出现范式转变，堪比语言模型中出现的效率提升。虽然像 Movie Gen 和 Step-Video-T2V 这样现有的高质量视频生成系统可能需要数百万美元的训练费用，但 Open-Sora2.0的训练支出仅约为20万美元。尽管成本大幅降低，但测试表明，其输出质量可与 Runway Gen-3Alpha 和 HunyuanVideo 等已建立的商业系统相媲美。该系统使用了224个 Nvidia H20
