Kling 1.6 Pro

A Kuaishou Technology névjegye

Alapítva: 2011 · Beijing, China

Kuaishou (Kwai outside China) is a major Chinese short-video platform founded in 2011 by Su Hua and Cheng Yixiao, often described as the principal domestic competitor to ByteDance's Douyin / TikTok. Kuaishou's AI Group (KLING team) launched the Kling video model in June 2024, instantly impressing the international community by producing 2-minute photorealistic clips before Sora was publicly available. The Pro tier (Kling 1.0 Pro, 1.5 Pro, 1.6 Pro) is positioned as Kuaishou's premium video model with higher resolution, better prompt adherence and longer durations than the Standard tier. Kling 1.6 Pro (released late 2024) was widely cited as the strongest publicly accessible Chinese video model at its time of launch, ahead of Hailuo and earlier Wan releases.

Architektúra

Diffusion Transformer (DiT) with 3D spatio-temporal VAE

Kling is a closed-source latent video diffusion model that Kuaishou describe as a Diffusion-Transformer (DiT) operating on a 3D spatio-temporal Variational Autoencoder. The 1.6 Pro variant generates clips up to 10 seconds at 1080p / 30 fps natively, with extension chains supporting up to 2 minutes. Text conditioning uses a bilingual large-language-model text encoder; image conditioning supports both first frame and end frame for guided shots. The architecture is reported to use 3D attention with full spatio-temporal mixing rather than factorised space/time attention, yielding stronger motion and identity coherence. Training uses a curated video corpus drawn in part from Kuaishou's vast platform data with synthetic dense captions; post-training reportedly combines reward-model alignment for aesthetics with caption-fidelity supervision and selective reinforcement on human-judged quality.
