Vidu Q4 Preview launches from ¥0.09/second as China's video-model trio splits paths
According to Zhi Dongxi and 36Kr, China's leading video-generation players refreshed their line-ups around the National Day holiday: Kuaishou's Kling AI announced Kling 4.0 on Sept 28, and Shengshu Technology released Vidu Q4 Preview on Oct 8, the first preview of its next flagship video model, priced from ¥0.09 per second. The article says Vidu Q4 Preview centres on expressive character acting, camera language and complex VFX, supports up to 4K output and 16-second single generations, and accepts up to 15 reference images plus three reference audio clips. It also claims the preview overtook Seedance 2.0 to rank third globally on Artificial Analysis, with MaaS image-to-video pricing of ¥0.59/s at 720p, ¥0.75/s at 1080p and ¥2.43/s at 4K, described as the lowest in the industry.
Falling per-second prices for flagship video models could lower the cost of test shoots and multi-version ad or short-drama experiments for small teams, though real output quality and leaderboard standings still need independent verification.
