LongCat Single Avatar (Image + Audio)

The LongCat Single Avatar (Image + Audio) model transforms static portraits into dynamic, ultra-realistic videos driven entirely by your own audio. Leveraging advanced AI and deep learning, this model generates lifelike, lip-synced avatar animations with natural facial expressions, smooth movements, and precise mouth synchronization. Simply upload a portrait image and an audio clip, provide a guiding text prompt, and watch as your avatar comes to life on screen. At its core, LongCat Single Avatar uses state-of-the-art video generation technology that analyzes both visual and audio cues. The model produces videos with remarkable realism, ensuring the avatar's lips, facial expressions, and head movements match the audio input perfectly. The result is an engaging, believable video that feels as though a real person is speaking, not just an animated still image. Customization is a key strength of this model. Users can control video style and content through detailed text prompts, while negative prompts help avoid unwanted artifacts or qualities.

For longer content, you can chain up to 10 video segments, each seamlessly animated for up to 5-6 seconds, making it ideal for presentations, explainer videos, virtual communication, and more. Advanced options cater to both novices and power users. Parameters like inference steps, text and audio guidance scales, and random seed control allow fine-tuning for optimal results. The model’s audio guidance features ensure accurate and expressive lip movements, while the integrated safety checker provides responsible content generation.
