什麼是「Sora」?
AI 人工智能聊天程式 ChatGPT 母公司公司 OpenAI 於日前宣布,將推出一款名為「Sora」的新 AI 模型,使用者只需透過簡單的文字指令,即可快速生成包含多名角色、特定場景的 1080p 解析度高畫質影片,目前影片的長度最高可達 60 秒。
像前面那個 17 秒的日本雪地櫻花紛飛影片,OpenAI 給予「Sora」的指令是「美麗、白雪皚皚的東京。 鏡頭穿過熙來攘往的城市街道,跟著幾個人享受美麗的下雪天,並在附近的攤位購物。 美麗的櫻花隨著雪花在風中飛舞。」
不過 OpenAI 官方也承認目前「Sora」模型尚未完備,仍有混淆空間細節、無法理解事件因果關係等缺失有待持續訓練,所以還有沒有開放給一般大眾使用,有興趣的科技迷不妨先看看 OpenAI 提出的其他多段「Sora」製作的作品,感受一下未來的影像震撼吧!
