Sora is a text-to-video model and social media app developed by OpenAI. The model generates short video clips based on prompts, and can also extend existing short videos. In February 2024, OpenAI previewed examples of its output to the public,[1] with the first generation of Sora released publicly for ChatGPT Plus and ChatGPT Pro users in the US and Canada in December 2024,[2][3] and the second generation, called Sora 2, was released to select users in the US and Canada at the end of September 2025.[4] It integrates social media features.[5][6]
By default, the generator uses copyrighted material in its videos (unless copyright holders actively opt-out of having their content included), and videos contain a visible, moving digital watermark to prevent misuse. However, only a week after Sora 2's release, third-party programs became prevalent which could remove the watermark.
