近日，OpenAI发布的文本生成视频模型Sora引起了广泛关注。根据用户提供的提示词，Sora能够生成高度逼真的视频。然而，网友反馈显示，Sora生成一分钟视频的时间需要超过一个小时，渲染效率引发了质疑。在Reddit社区，研究人员仅展示了预先选择的示例，并未向公众开放自定义提示词功能，且最长的演示视频仅持续了17秒。这意味着Sora在实际应用中的效率和便捷性可能不如预期。尽管Sora的发布展示了AI视频生成技术的进步，但其渲染时间过长的问题可能限制了其在实时内容创作和用户交互领域的应用。

英文新闻内容：
OpenAI recently unveiled its text-to-video model Sora, which can create realistic videos based on user prompts. However, users have reported that it takes over an hour to render a one-minute video, raising concerns about Sora’s efficiency. The developers have only showcased preselected examples and have not allowed public access to custom prompts, with the longest demo video clocking in at just 17 seconds. This suggests that Sora may not be as practical or user-friendly as hoped, potentially limiting its applications in real-time content creation and user interaction.
