Gemini Omni 1.1 Flash

官方和 Ext 渠道共用下方公开模型 ID，上游内部型号由服务器映射。

gemini-omni-1.1-flash

渠道与模型映射

官方渠道自动生成约 3–10 秒视频，不传 duration；支持参考图片、首尾帧和视频编辑。Ext 指定 4、6、8、10 秒，默认 6 秒。两条渠道均支持 360p、720p、1080p、4k，以及横屏、竖屏。

公开模型 ID 始终相同。固定时长选择 Ext；首尾帧、metadata.task 和任务续写选择 Official。两条渠道都兼容时由用户分组选路，因此仅省略 duration 并不能保证进入 Official 或自动时长。需要官方自动时长文生视频时使用 metadata.task=text_to_video。

参数约束

• Ext 参考图模式只接受 1 张或 3 张图片；2 张图片同时携带 generation_type: "reference" 和固定 duration 时，没有兼容路由。需要 2 张参考图时，可使用可用的 Official 渠道，传 metadata: {"task":"reference_to_video"}，省略 duration、seconds 和 generation_type；输出时长自动决定。
• last_frame_image 必须同时提供 first_frame_image。显式首尾帧字段与 image_with_roles 二选一，不能混用。
• Ext 中 duration（含 seconds 别名）与 video_urls 互斥；Official 不支持固定时长参数。
• ratio、size 是 aspect_ratio 的别名，不表示分辨率。同时提供时必须一致；duration 与 seconds 同传也必须一致。
• image_with_roles 每项包含 url 和 role，可用 first_frame、last_frame、reference；尾帧必须配首帧。素材使用公网可下载的 HTTP/HTTPS 直链。
• 接口仅接受表中 JSON 字段，不支持 multipart 上传，也不支持 seed、fps、negative_prompt、generate_audio、n、callback_url 等字段。
• video_urls 最多一段可下载视频；Official 编辑或续写的视频输入最长 10 秒。按任务续写须传本人已成功任务的公开 ID，并绑定原 Official 渠道。
• nsfw_check 为 Ext 布尔参数，上游默认 false。启用提交前审核可能产生额外审核费用。
