通过 Gravitex API 调用 Googlegemini-omni-flash-preview 视频生成模型。支持文生视频、单图图生视频，输出含音频的视频；任务为异步提交 + 轮询。另提供 Google Interactions 原生格式兼容路由。
| 能力 | 支持 | 说明 |
|---|---|---|
| 文生视频 | ✅ | prompt / input 传文本，内部 text_to_video |
| 图生视频 | ✅ | 文本 + 单张 Base64 图片，内部 image_to_video |
| 视频输出 | ✅ | 返回最终视频地址（含音频） |
| 异步任务 | ✅ | 提交后 GET 轮询 |
| 同步阻塞 / SSE | ❌ | 不支持 |
| 视频编辑 / 多图参考 | ❌ | 不支持 |
认证

必填
Bearer Token，如

模型与接口总览
| 模型 ID | 类型 | 文生视频 | 图生视频 | 输出 | 任务方式 |
|---|---|---|---|---|---|
gemini-omni-flash-preview | Gemini Omni Flash Preview | ✅ | ✅ 单图 | 视频（含音频） | 异步提交 + 轮询 |
| 接口 | 方法 | 用途 |
|---|---|---|
/v1/video/generations | POST | 平台视频格式提交任务 |
/v1/video/generations/{task_id} | GET | 平台视频格式查询任务 |
/v1beta/interactions | POST | Google Interactions 格式提交任务 |
/v1beta/interactions/{interaction_id} | GET | Google Interactions 格式查询任务 |
/v1beta 兼容接口最终仍走平台视频任务管线，不会改变其他模型的路由行为。平台视频接口
提交视频任务
POST https://api.gravitex.ai/v1/video/generations
{
"model": "gemini-omni-flash-preview",
"prompt": "生成一只正在草地上吃草的小羊",
"width": 1280,
"height": 720,
"duration": 3,
"seed": -1,
"metadata": {
"seconds": 3,
"resolution": "720p",
"aspectRatio": "16:9",
"durationSeconds": 3,
"watermark": false,
"camera_fixed": false
}
}
prompt 为必填。Gemini Omni 主要使用以下字段：
| 字段 | 类型 | 说明 |
|---|---|---|
model | string | 固定为 gemini-omni-flash-preview |
prompt | string | 文本提示词，必填 |
metadata.resolution | string | 当前推荐 720p |
metadata.aspectRatio | string | 16:9 或 9:16 |
metadata.durationSeconds | number | 建议 3–10 秒，实际受上游限制 |
metadata.image | string | 图生视频时传图片 Data URL |
{
"code": "success",
"message": "",
"data": {
"id": "video-xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx",
"object": "video",
"model": "gemini-omni-flash-preview",
"status": "in_progress",
"progress": 0
}
}
轮询任务
GET https://api.gravitex.ai/v1/video/generations/{task_id}
{
"code": "success",
"message": "",
"data": {
"id": "video-xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx",
"object": "video",
"model": "gemini-omni-flash-preview",
"status": "completed",
"progress": 100,
"url": "https://your-oss-host/video/xxxxxxxx.mp4"
}
}
in_progress。若上游仍在生成，平台保留任务并由后台继续轮询；若上游失败，返回失败原因。不要把 unknown 当作最终成功。
统一入口说明亦见 提交视频任务 与 查询视频任务。
Google Interactions 格式兼容接口
仅改变外部请求/响应形状，内部仍复用平台视频任务、轮询、结果交付与计费链路。提交与查询
POST https://api.gravitex.ai/v1beta/interactions
GET https://api.gravitex.ai/v1beta/interactions/{interaction_id}
文生视频示例
curl -X POST "https://api.gravitex.ai/v1beta/interactions" \
-H "Authorization: Bearer sk-xxxxxxxxxxxxxxxx" \
-H "Content-Type: application/json" \
-d '{
"model": "gemini-omni-flash-preview",
"input": "生成一只正在草地上吃草的小羊",
"generation_config": {
"video_config": {
"task": "text_to_video"
}
},
"response_format": {
"type": "video",
"aspect_ratio": "16:9",
"duration": "3s"
},
"background": true
}'
{
"id": "video-xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx",
"object": "interaction",
"model": "gemini-omni-flash-preview",
"status": "in_progress"
}
轮询示例
curl "https://api.gravitex.ai/v1beta/interactions/video-xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx" \
-H "Authorization: Bearer sk-xxxxxxxxxxxxxxxx"
{
"id": "video-xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx",
"object": "interaction",
"model": "gemini-omni-flash-preview",
"status": "completed",
"steps": [
{
"type": "video",
"content": [
{
"type": "video",
"uri": "https://your-oss-host/video/xxxxxxxx.mp4"
}
]
}
]
}
图生视频
兼容路由支持input 数组中的文本与单张图片 Data URL：
{
"model": "gemini-omni-flash-preview",
"input": [
{
"type": "text",
"text": "让这张图片中的小羊在草地上慢慢走动"
},
{
"type": "image",
"mime_type": "image/png",
"data": "iVBORw0KGgoAAAANSUhEUg..."
}
],
"generation_config": {
"video_config": {
"task": "image_to_video"
}
},
"response_format": {
"type": "video",
"aspect_ratio": "16:9",
"duration": "3s"
},
"background": true
}
image.uri 直接转为图片输入；需要图片时请传 data。
平台视频接口也可通过 metadata.image（Data URL）做图生视频。
响应与轮询
平台接口与原生兼容接口均为异步：提交只返回任务 ID 与进行中状态；客户端按 ID 轮询直至完成或失败。 状态映射：| 平台任务状态 | 原生兼容状态 | 说明 |
|---|---|---|
NOT_START / IN_PROGRESS | in_progress | 继续轮询 |
SUCCESS | completed | 可读视频地址 |
FAILURE | failed | 读错误信息并结束轮询 |
计费与用量
Google 官方 Gemini Omni 价格：输入 1.50/1Mtokens，文本输出（回答与推理）9 / 1M tokens，视频输出 0.10/秒；官方同时给出720p、含音频视频输出按17.50 / 1M 视频输出 tokens 的等价口径。官方价格页| 上游字段 | 平台含义 | 平台计费 |
|---|---|---|
total_input_tokens 或 input_tokens_by_modality | 输入 token | 输入 $1.50 / 1M |
total_thought_tokens、文本输出模态 | 文本回答与推理 token | 文本输出 $9 / 1M |
output_tokens_by_modality[modality=video] | 视频输出 token | 视频输出 $17.50 / 1M |
total_tokens | 上游总用量记录 | 用于审计，不直接替代三类计费拆分 |
