新浪科技讯 2月25日下午消息，新浪科技从知情人士处获悉，阿里巴巴将于今日晚间全面开源旗下视频生成模型万相2.1模型。
今年1月，阿里旗下万相刚宣布推出2.1 版本模型升级，视频生成、图像生成两大能力均获得提升。在视频生成方面，万相 2.1 通过自研的高效VAE和DiT架构增强了时空上下文建模能力，支持无限长1080P视频的高效编解码，首次实现了中文文字视频生成功能，登上VBench榜单第一。
据此前介绍，万相2.1支持中英文视频，可以一键生成艺术字，还提供多种视频特效选项，以增强视觉表现力，例如过渡、粒子效果、模拟等。
随着万相2.1模型开源，这意味着更多的开发者，将能够低成本获取并使用该模型底层代码，进而用以开展与自身业务相关的各类视频生成应用。
