OpenAI’s AI video generation app Sora has been downloaded more than 1 million times in less than five days since its launch. Although Sora is currently open on an invitation-only basis, its download speeds are already exceeding those of ChatGPT when it was first launched, Sora head Bill Peebles said on Wednesday.

OpenAI launched a new version of the Sora app on the iOS platform on September 30. Users can not only browse video content automatically generated by AI, but also generate videos independently based on the latest Sora 2 model. Sora has also introduced a “cameo” feature that allows users to insert themselves or their friends’ images into AI videos. According to our reporter Hayden Field’s experience, this application is full of various Internet memes, deep face-changing videos of OpenAI employees, and what can be called an “AI hodgepodge.”

The popularity of the Sora app has also sparked some controversy. Some users have generated copyrighted character content that is not suitable for brand communication environments, such as well-known cartoon images, which has prompted OpenAI to provide more control to relevant copyright holders and allow users to specify how their images are used on Sora.

Peebles said: "The team is working hard to cope with rapid growth, and more features and fixes for over-moderation issues are coming soon!" Sora is currently only available for download in the United States and Canada, and tops the Apple App Store.
