Alibaba's Wan family leapfrogged itself in a single generation. If you are choosing between Wan 2.7 and Wan 3.0 — or wondering whether to upgrade an existing workflow — this comparison covers the differences that matter in daily use.
Input flexibility is the biggest gap. Wan 2.7 handles text, images and first/last frames well, but stops there. Wan 3.0 accepts up to 10 reference images, 5 reference videos, 5 audio clips, a document and a webpage link in one request. For any project built on real materials — brand assets, actor references, voice samples — Wan 3.0 changes what is possible.
Duration is the second hard difference. Wan 2.7 works in fixed 5, 10 and 15-second steps, while Wan 3.0 generates any whole-second length from 2 to 30 seconds. Need a 7-second clip for a tight edit, or a 26-second storytelling shot? Wan 3.0 does it natively.
Audio also evolved: Wan 2.7 generates silent video, while Wan 3.0 produces native synchronized audio — dialogue, ambience and effects together with the visuals. That removes an entire post-production step for most projects.
Motion and consistency improved across the board in 3.0: multi-reference identity preservation is more stable, fast camera movement is smoother, and prompt adherence on complex scenes is noticeably better.
Where Wan 2.7 still shines: it remains a dependable, lower-cost option for straightforward text-to-video and image-to-video clips at 5 to 15 seconds, especially when you do not need references or native audio.
