Gemini Omni Flash

Google Gemini Omni Flash 视频生成,支持文生视频、单图生视频和三图融合,720P/1080P。

该模型已下线:CokeAPI 当前价目表中已不再提供 gemini_omni_flash,调用会返回模型不存在错误。请迁移到 Veo 3.1 Fast。本页仅作历史参考。

CokeAPI 接入 Google Gemini Omni Flash 视频模型。默认是异步任务: POST 创建后拿到 task_id,再通过 GET /v1/generations/{task_id} 轮询直到 succeeded。

图生视频提示:生成接口不再接收内联 base64 图片数据。请先使用文件上传接口上传参考图片获取 URL,再传入 image_urls。

模型 ID: gemini_omni_flash
