Sora is a video generation tool made by OpenAI. Users type a description, and Sora creates a short video clip with motion and sound. OpenAI first showed Sora in February 2024 and opened it to ChatGPT subscribers in December 2024.
In September 2025 OpenAI released Sora 2 along with a Sora app for phones. The app works like a social feed of short AI videos. Users can remix other videos and, with permission, place themselves or friends in scenes through a feature called cameos. Videos carry a visible watermark and content credentials. Users can describe the style, camera angle and mood they want, and then edit or extend the results.
Access depends on the user's ChatGPT plan and region, and paid plans allow more and longer videos. OpenAI also offers Sora to developers through its API. People use it for short social clips, concept videos and visual ideas. OpenAI is based in San Francisco.
