How LongCat Avatar Works

LongCat Avatar utilizes a unified AT2V (Audio-to-Video) and ATI2V (Audio, Text, Image-to-Video) model to convert user inputs into dynamic, lifelike avatar videos. The process involves three main steps:

1. Upload Your Photo: Provide a clear portrait image of the subject. High-quality images help preserve identity and improve motion realism.
2. Upload Your Audio: Supply an audio file—speech, singing, or any other type. The AI aligns mouth movements precisely with the audio for natural lip sync.
3. Generate Video: After uploading the required inputs, the system processes the data and generates a realistic, fluid talking video with coordinated motion and consistent identity.
