Which should you pick?

Use Veo 3.1 Fast while you are still working out whether the idea holds — the whole point of a cheap engine is that a draft you throw away costs very little. Switch to Veo 3.1 Fast for the version you intend to publish. Because Scenes AI shows you a scrubbable preview before any clips are bought, you can settle the structure cheaply and only pay the higher rate once.
