视频生成大模型群雄逐鹿 却不温不火
Zhong Guo Jing Ying Bao· 2025-06-27 08:17
在OpenAI发布的Sora爆火后,视频大模型开始出圈,国内就涌现出了腾讯混元、快手可灵等一系列视 频大模型,各有不同的优势特色。不过视频生成大模型行业高开低走,一年过去了,依旧处于不温不火 的状态。业内人士认为,一个重要原因在于,用户想看的短视频大都是由真人博主出演,而AI生成不 了这种视频。 对此,经济学家余丰慧告诉《中国经营报》记者:"关于可灵、即梦、混元这三个视频生成大模型,它 们各自拥有独特的技术优势和应用场景。可灵在图像识别和转换方面表现出色,适合需要高质量图像处 理的任务;即梦则以其强大的自然语言处理能力著称,能够根据文本描述生成相应的视频内容,特别适 用于创意产业;而混元结合了前两者的优点,并增加了更多的自定义选项,使其在灵活性和应用范围上 更具优势。因此,不能简单地说哪一个更好,而是应根据具体的使用需求来选择最适合的模型。" 竞争激烈 从国际方面来看,首先当然是OpenAI的Sora,Sora能生成长达60秒的高质量视频,在画面细节、动作流 畅度和镜头语言把控上较为均衡。目前Sora与ChatGPT Plus深度绑定,用户可在对话中一键体验,但因 为模型规模庞大,对GPU算力要求高,生成延迟 ...
