WaveSpeedWaveSpeedLip sync video generation from image and audio
InfiniteTalk is a lip sync model developed by WaveSpeed that generates synchronized talking-head video from a single portrait image and an audio file. It accepts image, audio, prompt, resolution, and seed inputs, giving users control over output quality and reproducibility. The model is priced starting at $0.15 per five seconds of generated video and was released in 2025.
InfiniteTalk is designed for use cases that require animating still images to match spoken audio, such as virtual avatars, dubbed content, and AI-generated presenters. Its input flexibility — including a resolution selector and seed parameter — allows developers to tune outputs for consistency across runs. The model is available through MindStudio without requiring separate API key management.
