Sora is OpenAI's tool for generating short video clips from a text description or an uploaded image. Users can type a scene — "a fox walking through a snowy forest" — and Sora produces a video clip, including sound. It launched publicly in December 2024 through sora.com and a mobile app.

Sora generates videos up to 20 seconds long at 1080p resolution and supports wide, vertical, and square formats. A second generation called Sora 2 arrived in September 2025, adding improved physics accuracy, synchronized dialogue and sound effects, and a "characters" feature. In December 2025, Disney invested $1 billion in OpenAI under a deal that allows Sora 2 users to generate characters from over 200 Disney, Pixar, Marvel, and Star Wars properties. Sora is available to ChatGPT Plus and Pro subscribers, and its underlying model is also accessible through the OpenAI Videos API.
