最新文字生成影片AI工具「Sora」強勢登場！OpenAI繼ChatGPT、DALL-E後，再推新的AI工具，妞妞們有跟上這波「Sora」話題嗎？（可不是韓國愛豆新人哦XD）讓手機小姐來速速簡介吧！

Introducing Sora, our text-to-video model.

Sora can create videos of up to 60 seconds featuring highly detailed scenes, complex camera motion, and multiple characters with vibrant emotions. https://t.co/7j2JN27M3W

Sora究竟是什麼呢？Sora是OpenAI訓練人工智慧模型理解和模擬動態物理世界後，進而產出影片的工具，簡單來說也就是「輸入文字生成影片」啦！只要輸入提示（文字敘述），就可以產生長達1分鐘的影片，既流暢逼真並符合用戶的指示，內文這幾支由OpenAI官方示範的影片都是Sora生成、完全無後製，妞妞們看得出來是AI生成的嗎？

Prompt: “Several giant wooly mammoths approach treading through a snowy meadow, their long wooly fur lightly blows in the wind as they walk, snow covered trees and dramatic snow capped mountains in the distance, mid afternoon light with wispy clouds and a sun high in the distance… pic.twitter.com/Um5CWI18nS

不管是風景、人物動物甚至是動畫風格，Sora都能產出這些主體或背景在動態之下的模樣，連風景的細節都非常逼真，難以看出是AI生成。

Prompt: “A stylish woman walks down a Tokyo street filled with warm glowing neon and animated city signage. she wears a black leather jacket, a long red dress, and black boots, and carries a black purse. she wears sunglasses and red lipstick. she walks confidently and casually.… pic.twitter.com/cjIdgYFaWq

不過OpenAI也提出，目前模型的運算能力未完備，還難以準確模擬複雜場景的物理原理，例如「一個人咬了餅乾後，餅乾需有咬痕」這類型的因果關係，現在依然在訓練階段。點進Sora的官方介紹頁還有許多示範影片，手機小姐覺得逼程度已經很高了捏！

看完以上影片範例，妞妞們會想玩玩看嗎？現階段Sora尚未開放給大眾使用！手機小姐很期待開放後網友的創作（詠唱）欸。除了Sora以外，Meta和Google其實也都推出了自己的文字生成影片工具，現在真的是大AI時代啦！
