Vidu S2 debuts: real-time interactive, editable and spatial AI video generation
_akhaliq · x · 2026-09-15
Shengshu Technology launched Vidu S2, a real-time interactive AI video model with three pillars:
- Vidu S2-Avatar: interactive characters at 720p and 25–42 FPS with stronger instruction following, expressive full-body motion and dancing; new reference images can be added mid-conversation to change outfits, interact with objects or switch scenes.
- Vidu S2-Editing: transforms an incoming video stream in real time while preserving motion and timing — style transfer, virtual try-on, character and background replacement.
- Spatial video: generated characters and live edits can be turned into stereoscopic video for VR.
The team claims SOTA results across all five public benchmarks in its evaluation, spanning avatar generation and video editing. A live demo, API and technical report (arXiv) are available.
