Integrate this model with one task-based API flow

Gemini Omni 1.1 Flash is Google's dedicated video generation model for developers and professional creators - and its defining feature is range: the same model outputs everything from 360p quick previews to 4K final renders, extends existing footage to 40 seconds through chained continuation, and accepts a 3-second reference clip to lock character and scene consistency. The examples below are rendered from Gemini Omni 1.1 Flash, the current gateway base URL, and the selected public model contract.

Input mode
X-API-Key on every request
POST /api/v1/openapi/task
GET /api/v1/openapi/task/status/{task_id}
Async task workflow

Single code window

Switch language once. Each example already includes both the task creation request and the task status polling request.

Request and response JSON become the documentation

Keep the payload and task status envelope as the primary contract. Field descriptions, optionality, and enum hints now live inline as JSON comments.

Request Body

Caller payload

This is the request envelope accepted by the public gateway for the selected model contract.
