Kling 2.X

Kling 2.6 Pro introduces native synchronized audio co-generation for dialogue, sound effects, and ambient soundscapes in a single pass, whereas Kling 2.5 Turbo Pro is optimized for rapid prototyping of silent cinematic video. Choose 2.6 Pro when your production requires aligned audio tracks directly from text scripting, and 2.5 Turbo Pro when you need faster iteration speeds, cost efficiency, and precise camera response.

Select Kling 2.1 Master when your scene demands the highest possible 3D spatiotemporal detail for close-up character acting and subtle facial micro-expressions. The Master tier delivers professional-grade focal depth and deep contrast, but operates at higher generation costs and longer render times than the Standard or Pro tiers.

Dual-keyframe conditioning allows you to supply both a start frame and an end frame to interpolate movement deterministically. This capability is exclusive to the 2.1 Pro variant, making it possible to create seamless infinite video loops by using the same frame for both inputs, or render controlled morphs between matching assets.

Kling is not suited for persistent, sharp typography, branding graphics, or scenes requiring independent coordination across multiple active characters. The model is optimized for single-subject physical dynamics, atmospheric environments, and emotional acting, but on-screen text and complex multi-character blocking may drift or warp over time.

Kling was developed by Kuaishou and first released in June 2024. The model family accepts text prompts along with start and optional end images, generating 30fps cinematic video in 5-second or 10-second clips across standard widescreen, vertical, or square aspect ratios.
