# 开源AI视频生成项目Open-Sora(安装失败)

# 什么是Open-Sora

首先，此 Open-Sora 并非 Open AI 发布的 Sora 开源版。

Open-Sora项目是一项致力于高效制作高质量视频，并使所有人都能使用其模型、工具和内容的计划。通过采用开源原则，Open-Sora 不仅实现了先进视频生成技术的低成本普及，还提供了一个精简且用户友好的方案，简化了视频制作的复杂性。通过 Open-Sora，我们希望更多开发者一起探索内容创作领域的创新、创造和包容。

# windows系统下部署

虽然Open-Sora目前的效果和Sora还有一些差距，生成视频的效果和长度都还有很大改善空间，但是优点在于完全开源，灵活性更高，而且是目前唯一能用上的模型。所以这篇文章就来介绍如何在单机上部署Open-Sora并进行文生视频推理。之后的文章会介绍如何将Open-Sora部署为可支持多人在线调用的API服务。

（Open-Sora一共需要下载20多个G的模型）、数据盘可以单独保存使得我们不用每次部署都重新下载模型。虽然Open-Sora目前的效果和Sora还有一些差距，生成视频的效果和长度都还有很大改善空间，但是优点在于完全开源，灵活性更高，而且是目前唯一能用上的模型。所以这篇文章就来介绍如何在单机上部署Open-Sora并进行文生视频推理。之后的文章会介绍如何将Open-Sora部署为可支持多人在线调用的API服务。
