Veo 3.1 Fast
Google (Veo 3.1 Fast)
The middle of the Veo family — still the Veo look, at a fraction of the cost. Google Veo 3.1 Fast — Veo quality at a third of the flagship rate.
Using Veo 3.1 Fast in uooki
uooki has no model picker. You name the model in the conversation and the agent routes to it — “make the clip with Veo 3.1 Fast” is the whole interface. Common spellings and older ids resolve to the same model, so you do not have to match our internal naming.
Leave the model out and the agent picks one for you based on what you asked for. Naming it is for when you have a reason to — this page is about those reasons.
What it is good at
- Veo quality on a budget
- Generating several takes and picking one
Where it is not the right pick
Less detail and less stable motion than the 3.1 flagship, and complex camera moves show the gap. Still billed **per clip**, so short clips save you nothing beyond the lower per-clip rate.
When to reach for something else
- Veo 3.1
The clip is final and the detail gap shows.
- Veo 3.1 Lite
You are still validating the script and want the cheapest Veo.
- Hailuo 2.3
You do not need audio, in which case per-second billing is cheaper.
