最快的 AI 视频生成器是什么？

Short answer

Seedance 2 Fast 是获得全质量输出的最快路径，每秒 0.266 美元（约 1.33 美元/5 秒），而 LTX 2 每个片段约 0.09 美元，是迭代最快的方式，因为重试几乎不花钱。公布的挂钟延迟各不相同；所有任务均异步运行。

The evidence

速度分级定价的存在是有原因的。

Seedance 2 Fast 为 0.266 美元/秒（约 1.33 美元/5 秒，从 128 积分起），而标准 Seedance 2 为 0.334 美元/秒。

廉价迭代胜过原始延迟。

以9积分（约0.09美元）生成一个LTX 2片段，重试提示词直到时序合适，十次尝试的成本不到1美元。

异步任务将速度与你的技术栈解耦。

具有任务ID的持久任务确保队列高峰时不丢失请求；可轮询或订阅完成通知。

图像才是真正的快车道。

Z-Image是原生4步涡轮生成器，每张图像0.04美元，当静态帧比任何视频渲染更快时，它是最佳选择。

不虚构延迟数据。

实际耗时取决于负载和分辨率；公布的事实是价格和任务语义，而非基准测试的毫秒数。

Frequently asked questions

+哪个AI视频模型返回草稿最快？

Seedance 2 Fast是速度档，价格为0.266美元/秒（约1.33美元/5秒）。若追求纯迭代速度，LTX 2片段约0.09美元，重试成本极低。

+我需要同步等待视频结果吗？

不需要。生成是异步的，带有持久任务ID；你的应用轮询或收到通知即可。

+预览镜头的最快方式是什么？

先用9积分（约0.09美元）生成LTX 2片段，或用0.04美元生成Z-Image静态图，再决定是否投入Seedance 2渲染。
