Kling AI 发布 4.0：30 秒视频、立体声音频与多语言口型同步
Kling AI drops version 4.0 with stereo audio, multilingual lip sync, and a lighter Flash variant
快手家的 Kling 4.0 来了，能生成 30 秒带立体声的视频，口型同步还支持多语言，不过和 Wan、Seedance 打了个平手。
Kling AI 发布视频生成模型 4.0 版本，支持最长 30 秒的片段生成。新版本可输入最多 10 张关键帧图片，提示词理解容量扩展到 8,000 tokens，并新增立体声音频和多语言口型同步功能。与 Wan 3.0 和 Seedance 2.5 的对比测试中，Kling 4.0 表现相当但没有明显领先，这可能意味着 AI 视频模型的进步速度开始放缓。此次更新还包含一个更轻量的 Flash 变体。

Kling AI has released version 4.0 of its video generator with support for clips up to 30 seconds, ten keyframe images as input, and prompt comprehension expanded to 8,000 tokens. In comparisons with Wan 3.0 and Seedance 2.5, Kling 4.0 holds its own but doesn't pull ahead, which could be an early sign that the breakneck pace of progress in AI video models is starting to level off.
