Wan 3.0 vs Sora 2
Wan 3.0 (Alibaba) and Sora 2 (OpenAI) are the two long-form video models on Arteza, and they get there differently. Wan 3.0 generates up to 30 seconds in a single pass, with native audio and three resolution tiers you can trade cost against. Sora 2 goes up to 20 seconds and optimizes for physically believable motion at 720p. Both run on the same credit balance, and the costs below come from the live pricing engine.

Choose Wan 3.0 when
- The shot has to run longer than 20 seconds without a cut, which no other model on Arteza does in one pass.
- You want to steer the result with references: up to ten reference images plus reference video and reference audio in the same request.
- You are cost-sensitive across a lot of takes: rough the shot in at 480p, review at 720p, and only pay the 1080p rate on the version you deliver.
The bottom line
Length and control point to Wan 3.0; motion realism points to Sora 2. Wan 3.0 is the only model here that will hold a 30 second take, and its 480p tier is the cheapest way on Arteza to find out whether a shot works at all before committing to a finished render. Sora 2 stays the better answer when the action itself has to look real. Since both sit in the same video studio on one credit balance, running the identical prompt through each costs a few credits and settles it for your footage rather than in the abstract.
Frequently asked questions
How long can Wan 3.0 and Sora 2 clips be?
Wan 3.0 generates 2 to 30 seconds in a single pass. Sora 2 generates 4 to 20 seconds. Both are priced per second, so the credit cost scales with the length you pick, and the studio shows the exact figure before you generate.
Does Wan 3.0 generate audio?
Yes. Wan 3.0 renders native audio along with the video, and there is a toggle in the studio if you want the clip silent. Turning it off does not change the price.
What is the difference between Wan 3.0 and Wan 3.0 Prime?
Same controls, same 30 second ceiling, same three resolution tiers. Prime is the higher-fidelity tier and costs more per second. Both are in the Arteza video studio, so you can draft on Wan 3.0 and re-render the winner on Prime.
Can I give Wan 3.0 a reference video or a reference audio track?
Yes. Wan 3.0 accepts up to ten reference images, five reference videos, and five reference audio clips in one request, alongside the prompt. Sora 2 takes a text prompt and one optional image.
