OpenAI’s new video generation app, Sora, has become the number one free application in Apple’s App Store shortly after its release. Ashley Capoot reports for CNBC. The app achieved the top spot despite being available by invitation only. With Sora and its popular chatbot ChatGPT, OpenAI now holds two of the top three positions in the store’s charts. The app allows users to create and remix short AI videos and share them in a social feed. “It’s been epic to see what the collective creativity of humanity is capable of so far,” wrote Bill Peebles, head of Sora at OpenAI, in a social media post regarding the user-generated content.
