Overview

Sora Overview

Sora is a text-to-video AI model developed by OpenAI, previewed in February 2024 and officially released to the public in December 2024. Sora generates videos up to 60 seconds long with high realism and creativity from text descriptions.

Sora uses a Diffusion Transformer architecture, treating video as sequences of spatiotemporal patches, enabling generation of videos with complex scenes, multi-character interactions, and accurate physical motion. It supports text-to-video, image-to-video, and video editing capabilities.

Sora is currently available at sora.com to ChatGPT Plus and Pro subscribers, and is OpenAI's flagship product in the video generation space.
