# Minimax Hailuo-02

Minimax Hailuo-02 is an AI video generation model supporting both text-to-video and image-to-video. It can generate 6-second videos at 768P or 1080P resolution, and 10-second videos at 768P resolution.

<Tip>
  This is an **async** API that only returns the task\_id of the async task. Use the task\_id to call the [Get Async Task Result API](/docs/models/reference-get-async-task-result) to retrieve the generated result.
