Poll `GET /videos/generations/{task_id}` with the returned `task_id` until the task reaches a terminal state. If the POST request times out or its result is uncertain, do not blindly retry it. The original request may already have created another task and billing order. Completed asset URLs are dynamically signed. Download or copy assets that must be retained instead of treating the URLs as permanent identifiers. operationId: gemini-omni-1-2-flash requestBody: required: true content: application/json: schema: type: object properties: model: type: string enum: - gemini-omni-1.2-flash description: 'Must be one of: gemini-omni-1.2-flash.' duration: type: integer default: 5 minimum: 3 maximum: 15 description: >- 3–10 seconds for interpolation and extend.
