# Grok Imagine 模型

Grok Imagine 与 Grok Imagine 1.5 的模式、输入、默认值、积分价格和 API 示例。

## 概览

**厂商：** Grok（xAI）。`grok-imagine` 和 `grok-imagine-1-5`（Grok Imagine Video 1.5 Fast）根据文本或单张图片生成视频。两个模型都没有音频开关。

## 模式与输入

| 模型               | 模式             | `image_urls` | 时长                   | 分辨率     | 画面比例                  | 默认值         |
| ------------------ | ---------------- | ------------ | ---------------------- | ---------- | ------------------------- | -------------- |
| `grok-imagine`     | `text-to-video`  | 无           | 6s, 10s, 15s, 30s      | 480p, 720p | 2:3, 3:2, 1:1, 9:16, 16:9 | 6s, 480p, 16:9 |
| `grok-imagine`     | `image-to-video` | 恰好 1 张    | 6s, 10s, 15s, 30s      | 480p, 720p | 2:3, 3:2, 1:1, 9:16, 16:9 | 6s, 480p, 16:9 |
| `grok-imagine-1-5` | `text-to-video`  | 无           | 6s, 10s, 15s, 20s, 30s | 480p, 720p | 16:9, 9:16, 1:1, 3:2, 2:3 | 6s, 480p, 16:9 |
| `grok-imagine-1-5` | `image-to-video` | 恰好 1 张    | 6s, 10s, 15s, 20s, 30s | 480p, 720p | 16:9, 9:16, 1:1, 3:2, 2:3 | 6s, 480p, 16:9 |

两个模型都不接受 `video_urls`。

## 积分价格

### `grok-imagine`

两种模式相同。

| 分辨率 | 6s  | 10s | 15s | 30s |
| ------ | --- | --- | --- | --- |
| 480p   | 10  | 20  | 30  | 60  |
| 720p   | 20  | 30  | 45  | 90  |

### `grok-imagine-1-5`

两种分辨率、两种模式均为每秒 3 积分。

| 时长 | 6s  | 10s | 15s | 20s | 30s |
| ---- | --- | --- | --- | --- | --- |
| 积分 | 18  | 30  | 45  | 60  | 90  |

## 示例

```bash
curl -X POST https://viewmax.studio/api/v1/videos \
  -H "Authorization: Bearer $VIEWMAX_API_KEY" \
  -H "Content-Type: application/json" \
  -H "Idempotency-Key: grok-example-0001" \
  -d '{
    "model": "grok-imagine-1-5",
    "mode": "image-to-video",
    "prompt": "The camera slowly pushes toward the subject",
    "image_urls": ["https://example.com/source.jpg"],
    "options": { "duration": "10s", "resolution": "720p", "aspect_ratio": "16:9" }
  }'
```

该请求消耗 30 积分。通过 MCP 时，调用 `generate_video` 并使用相同的模型 ID。
