OpenAI now has two of the top three free apps in Apple's App Store, and its new video generation app Sora has snagged the coveted No. 1 spot. The artificial intelligence startup launched Sora on Tuesday, and it allows users to generate short-form AI videos, remix videos created by other users and post them to a shared feed. Sora is only available on iOS devices and is invite-based, which means users need a code to access it. Despite these restrictions, Sora has secured the top spot in the App Store, ahead of Google 's Gemini and OpenAI's generative chatbot ChatGPT. "It's been epic to see what the collective creativity of humanity is capable of so far," Bill Peebles, head of Sora at OpenAI, wrote in a post on X on Friday. "Team is iterating fast and listening to feedback."
