When to use Seedance 2.0 Fast
Seedance 2.0 Fast trades the resolution ladder for turnaround. It exposes no resolution choice at all, which is the point: there is one output profile, so there is one price per second and no decision to make. It accepts the same text, reference image and reference video inputs as the rest of the Seedance 2.0 family and ships native audio with every clip. Reach for it when the bottleneck is your own iteration loop rather than the credit budget, for example when you are sitting with a client or a teammate and want to see three different takes on an idea inside a few minutes, or when an autopilot run has to produce a day of content on a schedule and cannot afford a slow queue. It sits above Mini on cost and below the full Seedance 2.0, so it is the sensible middle when Mini's detail is not quite holding up but you do not need 1080p or 4K. Do not choose it when the deliverable has a specific resolution requirement, because you cannot ask for one here. Do not choose it either when you are generating a large batch overnight, since nothing is waiting on the result and the cheaper Mini would have done the same job. In practice this model earns its place in live sessions and in scheduled autopilot runs, and it is worth remembering that the same prompt and references can be moved to the full Seedance 2.0 later without any rework. One more thing worth knowing: because there is only one output profile, the price you see on the first clip is the price of every clip, which makes it the easiest model in the family to budget a week of content against.
