2月16日凌晨,OpenAI在其官网发布了一项创新性的文生视频模型——Sora。

通过OpenAI在官网展示的Sora生成视频的效果,可以看出其在生成视频质量、分辨率、文本语义还原、视频动作一致性、可控性、细节以及色彩等方面表现出色。

据OpenAI官网披露,OpenAI首个视频生成模型Sora正式发布,充分继承了DALLE 3的卓越画质和出色的遵循指令能力,具备生成长达1分钟高清视频的能力

OpenAI声称,只需提供简短或详细的描述,或者一张静态图片,Sora就能够生成类似电影的1080p场景,其中包含多个角色、各种动作和丰富的背景细节。

消息发布后,Sam Altman的言论引发了广泛的讨论,一些网友和工程师表示难以置信。有人猜测,这一技术的出现可能会对好莱坞电影产业产生深远影响,甚至有人质疑是否标志着好莱坞时代的结束。

其实,Sora的最大意义并非仅仅在于生成的视频有多逼真,而在于展示了能够理解和模拟现实世界的模型的初步雏形。OpenAI认为,这将是实现人工通用智能(AGI)的重要里程碑。

Sam Altman在不久前曾表示,GPT-5将经历指数级的跃升,人类离达到AGI的目标已经非常接近。我们很快将能够亲眼见证这一时刻。
