Wan 3.0 vs Wan 2.7: I Opened Alibaba's Own Demo Files. Three Specs Everyone Copied Are Wrong.

Wan 3.0, Alibaba’s public-beta video generation model, expands single-pass video length to 30 seconds, supports up to 20 references and new inputs such as documents and web pages, and is designed for timestamped, multi-shot prompts with generated audio, while Wan 2.7 is a production-oriented model limited to 15 seconds for text/image video and 10 seconds for reference and editing workflows. The comparison argues that common claims about Wan 3.0 offering native 4K resolution or open weights are inaccurate: its listed output tiers stop at 1080P, its official examples often use a 1920×1072 format, and neither Wan 3.0 nor Wan 2.7 has publicly released weights, with Wan 2.2 remaining the newest locally usable family. Wan 2.7 can currently offer higher super-resolution options up to 1440P-SR and is available through third-party APIs, whereas Wan 3.0 is restricted to Alibaba’s first-party beta services. The main practical difference is narrative runtime and reference capacity, but prompts must be structurally rewritten for Wan 3.0’s multi-scene format, as Wan 2.7 clip continuation cannot reliably create a seamless 30-second generation. Pricing is broadly comparable per second at baseline resolution, although 30-second outputs increase total project cost, and the text notes that beta terms, audio quality, text accuracy, and commercial licensing remain factors to verify.
