Open vs API-only, what changed
Wan 2.x shipped with public weights and a permissive Apache 2.0-style license. Wan 3.0 launched API-only — Alibaba hosts it first-party, weights are not published, and OneInfer routes it through five published gateways. Reproduce your existing Wan 2.7 workload against Wan 3.0 on a fixed prompt set before switching production traffic.

Wan 3.0 extends the Wan 2.x line with 30s native duration (vs ~8s for Wan 2.7), document-to-video input that earlier versions did not expose, and audio composed within the same pass rather than added on top. The trade-off is API-only access and roughly 40 percent higher per-second pricing than Wan 2.x gateways.
