Sora 2 (reverse) is a state-of-the-art video + audio generator. It improves on the original Sora with more accurate physics, clearer realism, synchronized audio, stronger controllability, and a broader range of styles.
This is an asynchronous API and only returns the task_id of the asynchronous task. You should use this task_id to request the Get Task Result API to retrieve the video generation result.
