A fast version of the [hailuo-2.3](https://docs.aimlapi.com/api-references/video-models/minimax/hailuo-2.3) model. Delivers more expressive motion and produces visuals that are both more realistic and stable and introduces major improvements in the depiction of physical actions, stylization, and subtle character expressions, while also further refining its responsiveness to motion commands.

## Setup your API Key

## How to Make a Call

<details>

<summary>Step-by-Step Instructions</summary>

Generating a video using this model involves sequentially calling two endpoints:

* The first one is for creating and sending a video generation task to the server (returns a generation ID).
* The second one is for requesting the generated video from the server using the generation ID received from the first endpoint.

Below, you can find both corresponding API schemas.

## API Schemas

### Create a video generation task and send it to the server

## POST /v2/video/generations

>

```json
{"openapi":"3.0.0","info":{"title":"AIML API","version":"1.0.0"},"servers":[{"url":"https://api.aimlapi.com"}],"paths":{"/v2/video/generations":{"post":{"operationId":"_v2_video_generations","requestBody":{"required":true,"content":{"application/json":{"schema":{"type":"object","properties":{"model":{"type":"string","enum":["minimax/hailuo-2.3-fast"]},"prompt":{"type":"string","maxLength":2000,"description":"The text description of the scene, subject, or action to generate in the video."},"image_url":{"type":"string","format":"uri","description":"A direct link to an online image or a Base64-encoded local image that will serve as the first frame for the video.\nImage specifications: \n- format must be JPG, JPEG, or PNG; \n- aspect ratio should be greater than 2:5 and less than 5:2; \n- the shorter side must exceed 300 pixels; \n- file size must not exceed 20MB."},"resolution":{"type":"string","enum":["768P","1080P"],"default":"768P","description":"The dimensions of the video display. 1080p corresponds to 1920 x 1080 pixels, 768p corresponds to 1366 x 768 pixels."},"duration":{"type":"integer","description":"The length of the output video in seconds.","enum":[6,10]},"enhance_prompt":{"type":"boolean","default":true,"description":"If True, the incoming prompt will be automatically optimized to improve generation quality when needed.

```

### Retrieve the generated video from the server

After sending a request for video generation, this task is added to the queue. This endpoint lets you check the status of a video generation task using its `id`, obtained from the endpoint described above.\
If the video generation task status is `completed`, the response will include the final result — with the generated video URL and additional metadata.

## GET /v2/video/generations

```json

```

## Code Example

The code below creates a video generation task, then automatically polls the server every **15** seconds until it finally receives the video URL.
