OpenAI launched Sora 2, its new video generation model, along with a new iOS app called Sora built around it. Sora 2 generates video with synchronized audio, including dialogue and sound effects, and more accurate physics. The invite-based app rolled out first in the United States and Canada, featuring a short-video feed and a "cameo" feature for inserting one's own likeness and voice into videos, drawing wide attention as a TikTok-style AI video app.
