# Minimax Hailuo 2.3 Fast Image-to-Video

Minimax Hailuo 2.3 Fast significantly improves generation speed while maintaining excellent image quality and expressiveness, offering greater cost-effectiveness.

<Tip>
  This is an **asynchronous** API and will only return the asynchronous task's task\_id. You should use this task\_id to request the [Get Task Result API](/en/docs/models/reference-get-async-task-result) to retrieve the video generation result.
