Kling AI Avatar v2 Standard

Kuaishou's Kling AI Avatar v2 Standard is an image-to-video model built specifically for audio-driven talking-head generation. By processing a single portrait image alongside an audio track, it creates synchronized lip-sync animations. It is used by creators and marketers to produce explainer videos, social media clips, and product announcements without a camera. The model supports realistic human portraits, animals, cartoons, and stylized characters, maintaining consistent facial movements throughout the generated speech.

Developed by Kuaishou, Kling AI Avatar v2 Standard was released in December 2025 as a major upgrade to Kling's original Custom AI Avatar feature. This v2 release introduced improved hand stability, support for longer generation times up to five minutes, and more accurate lip-syncing. The Standard tier is optimized for speed and lower-cost everyday use. For projects requiring broadcast-level 1080p fidelity and highly expressive motion, Kuaishou also offers Kling AI Avatar v2 Pro.

Provide a high-resolution, front-facing portrait where the subject is well-lit and clearly visible. Because the model maps waveforms directly to facial movements, you must use clean audio with minimal background noise and clear enunciation. You can also use an optional text prompt to steer the avatar's attitude and setting, such as "warm smile, steady eye contact, professional." To minimize unwanted or excessive hand gestures, avoid high-energy prompt words like "enthusiastic," "animated," or "dynamic."
