2月16日，OpenAI宣布推出全新的生成式人工智能模型“Sora”，引发了广泛关注。
媒体2月17日报道，市场预计，在最新一轮由风投公司Thrive Capital牵头融资中，OpenAI的估值有望超过800亿美元；而去年年初ChatGPT刚发布不久后，OpenAI的估值大约为290亿美元。
Sora只是小试牛刀，它展现的不仅仅是一个视频制作的能力，而是大模型对真实世界有了理解和模拟之后，会带来新的成果和突破。
2月16日凌晨，OpenAI再次扔出一枚深水炸弹，发布了首个文生视频模型Sora。
据介绍，Sora可以直接输出长达60秒的视频，并且包含高度细致的背景、复杂的多角度镜头，以及富有情感的多个角色。
例如一个Prompt（大语言模型中的提示词）的描述是：在东京街头，一位时髦的女士穿梭在充满温暖霓虹灯光和动感城市标志的街道上。
在Sora生成的视频里，女士身着黑色皮衣、红色裙子在霓虹街头行走，不仅主体连贯稳定，还有多镜头，包括从大街景慢慢切入到对女士的脸部表情的特写，以及潮湿的街道地面反射霓虹灯的光影效果。
I cannot be much happier when I saw the news! I recently was invited to invest in OpenAI.
As an investor in the company, what can make me more proud than witnessing its great strike in its business development？！ Honestly I thought I was too late to put money onto it after it had already been so successful in the AI world, especially when there are so many competitors out there. But Sora has definitely given me a lot of confidence on the bright future of the company, or more so on its CEO, Sam Altman! If you don't know yet, see this report about his ambition: OpenAI CEO Sam Altman seeks as much as $7 trillion for new AI chip project.
