今年早些时候给大家介绍了 AI 视频生成 Agent Medeo 的 0.5 版本，当时他们已经算是这个品类的先行者了。 后来又有很多视频 Agent 发布，我也陆陆续续尝试了一些，但发现大部分的执行路径都非常死板，要不泛化性不强，要不完全无法通过 自然语言指挥模型进行修改和调整。 前几天拿到了 Medeo 的 1.0 版本，进步非常大，试了一下以后感觉相当惊艳， 文章后有邀请码抽奖 。 非常短的提示词可以出不错的效果这个是基本功，但是他们也可以支持非常灵活的通过 自然语言进行修改 ，支持 超过上千字的超长提示词，提供 非常好的泛化性 ，各种风格和垂类视频都可以做。 先来看一下我用他做的几个视频： 这是一个科普猎鹰九号助推器回收难度的视频，非常清晰企且直观的讲解了猎鹰九号火箭回收的意义和难度。 为我设计的 Vibe Coding 键盘做的宣传片，他可以很完美的还原任何产品，哪怕是全新设计的 将任何小说或者影视剧转换为哈基米宇宙的风格，这里是《诡秘之主》中克莱恩蜕变的那部分剧情 这些视频我都 总结了提示词，你们可以一键复刻 ，而且很通用，基本可以搞定一整个品类。 可以让优质创作者将自己的创作智能和创作逻辑压缩到 ...
