ChatGPT maker OpenAI released its AI-generated video tool called Sora for general use by its paying customers Monday. The company then said it would do wide testing with creatives and red-teaming with security experts before its release to the public. “We don’t want the world to just be text,” OpenAI CEO Sam Altman said in a live-streamed announcement Monday.

“[Video] is important to our culture,” Altman added. The company said in a statement that the latest version of Sora, which will be offered as a standalone product to ChatGPT Plus and Pro customers, is “significantly faster” than the one it previewed. It lets you generate videos up to 20 seconds long.
