kwaivgi/kling-v2-ai-avatar-pro

Create high-quality talking-head avatar videos from a single portrait and your own audio.

kwaivgi/kling-v2-ai-avatar-pro is an image-to-video model designed for AI avatar generation. It turns a single portrait image and an audio track into a clean, stable, lip-synced talking-head video with strong identity consistency. With no cold start, strong output quality, and affordable usage-based pricing, it is well suited for social content, profile videos, intros, and virtual presenter workflows.

🚀 Key Features

  • Audio-driven lip sync: Uses uploaded audio directly rather than synthetic speech, preserving timing, pauses, and emotional delivery.
  • Strong identity consistency: Maintains facial characteristics from the reference image while animating the face, eyes, and head naturally.
  • Stable talking-head motion: Optimized for clean, on-camera avatar performance with controlled movement and reliable visual coherence.
  • One-shot workflow: Requires only one Image and one Audio input, eliminating the need for video capture or motion recording.
  • Prompt-guided styling: Supports optional Prompt input to influence mood, expression, lighting feel, or subtle camera presence.
  • Social-ready vertical output: Ideal for short-form vertical content formats used across TikTok, Reels, Shorts, and Stories.
