Alibaba has officially launched Wan 2.5 Preview, a groundbreaking AI model that represents a paradigm shift in video generation technology. Unlike previous models that only create visuals, Wan 2.5 natively integrates text, images, video, and audio into a unified framework—creating complete videos with synchronized sound directly from descriptive prompts.
Native Audio-Visual Synthesis
The Killer Feature
Wan 2.5’s most revolutionary capability is its native audio integration. For the first time, users can generate complete videos with organically produced audio—no additional editing tools or third-party software required.
This means:
- ✅ Background music generated to match the scene mood
- ✅ Sound effects synchronized with visual actions
- ✅ Ambient sounds that enhance realism
- ✅ Consistent audio-visual timing throughout the video
Why This Matters
Previous AI video generators required users to:
- Generate silent video
- Find or create separate audio
- Manually sync audio with video
- Edit and fine-tune in post-production
Wan 2.5 eliminates all these steps, producing ready-to-use video content from a single prompt.
