# AIGC GV VOD Guide

`aigc-video-gv-*` models are GV / Google Veo video models exposed through Crazyrouter's Tencent VOD route. They use the same OpenAI-style async video route as AIGC Kling VOD:

```http theme={null}
POST /v1/video/generations
GET /v1/video/generations/{task_id}
```

<Note>
  `aigc-video-gv-*` only uses `/v1/video/generations` and the matching query route. Do not send these models to `/v1/video/create`; a route mismatch will surface as `model_not_found` or a similar upstream error.
</Note>

## Available Models

| Model                    | Upstream version | Notes                                  |
| ------------------------ | ---------------- | -------------------------------------- |
| `aigc-video-gv-3.1`      | GV 3.1           | Quality version with audio support     |
| `aigc-video-gv-3.1-fast` | GV 3.1 Fast      | Faster version with audio support      |
| `aigc-video-gv-3.1-lite` | GV 3.1 Lite      | Lightweight version with audio support |

<Note>
  Tencent VOD GV 3.1 is a Google Veo route, not Kling. Do not use model names such as `aigc-video-kling-3.1`.
</Note>

## Create a Task

```bash cURL theme={null}
curl -X POST https://api.crazyrouter.com/v1/video/generations \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "aigc-video-gv-3.1-fast",
    "prompt": "a cinematic product shot with natural camera movement",
    "seconds": "5",
    "metadata": {
      "resolution": "1080P",
      "sound": true
    }
  }'
```

## Image and Multi-Image Reference

Use `image` for a single input image. For multi-image references, use `metadata.image_list`:

```bash cURL theme={null}
curl -X POST https://api.crazyrouter.com/v1/video/generations \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "aigc-video-gv-3.1",
    "prompt": "combine the visual style of the references into one smooth shot",
    "seconds": "5",
    "metadata": {
      "resolution": "1080P",
      "image_list": [
        {
          "url": "https://example.com/ref-1.png",
          "reference_type": "asset"
        },
        {
          "url": "https://example.com/ref-2.png",
          "reference_type": "style"
        }
      ]
    }
  }'
```

<Warning>
  GV multi-image input must be sent through `FileInfos`. Crazyrouter converts `image_list` into `FileInfos` and does not use `LastFrameUrl` for GV multi-image requests.
</Warning>
