API ReferenceVideo Generation

Generate video from text

Generate a video from a text prompt. Describe the scene, camera motion, and mood — the model returns a video with matching audio. Returns the generated video directly in the response. For an asynchronous version that returns a job to poll, see [v2/text-to-video](/api-documentation/api-reference/async-video-generation/submit-text-to-video). Billed per second of generated video. See [Pricing](/pricing).
