One-line verdict: Sora is out of the race (discontinued April 2026), so this is really a two-horse comparison. Veo 3.1 wins on raw cinematic quality and the most polished native audio — pick it for hero shots and ads. Kling 3.0 wins on value: a genuinely generous free tier, 4K/60fps output, and direct access in China — pick it for volume work, short-form content, and getting started. In China, Kling is the only practical choice of the three.
一句话结论：Sora 已退出比赛（2026 年 4 月停服），实际是两强对比。Veo 3.1 赢在电影级画质和最精致的原生音频——做精品镜头和广告选它；可灵 3.0 赢在性价比——真正大方的免费额度、4K/60fps 输出、国内直接可用——做批量生产、短视频和入门选它。在国内，可灵是三者中唯一实际可用的选择。

Why Compare These Three?为什么要对比这三家？
Sora (OpenAI) ignited the AI-video wave, but OpenAI shut down the apps in April 2026 and the API in September 2026 — it now serves only as a historical benchmark.Sora（OpenAI）曾引爆 AI 视频浪潮，但 OpenAI 在 2026 年 4 月关停应用、9 月下线 API，如今只能作为历史参照。
Google Veo 3.1 is the current quality leader: native synchronized dialogue and sound effects generated in a single pass, true 4K output, and the Flow filmmaking app — at premium pricing.谷歌 Veo 3.1 是当前画质标杆：原生同步对白和音效一次生成、真 4K 输出、配套 Flow 电影制作应用——价格也偏高端。
Kling 3.0 (Kuaishou, 快手可灵） is the value champion: native audio with lip-sync, native 4K at 60fps, AI Director multi-shot sequencing, a free tier of 66 credits per day, and direct availability in China.可灵 Kling 3.0（快手）是性价比之王：原生音频带唇形同步、原生 4K/60fps、AI 导演多镜头编排、每天 66 积分免费额度、国内直接可用。
