Google Flow (Veo 3.1)
Any Google account gets 50 free credits daily plus 100 starter credits, equivalent to roughly 2-3 Veo 3.1 Fast clips per day
Each clip runs 4-8 seconds and can be chained up to roughly 148 seconds. Credits don't roll over to the next day; the first generation you make starts the countdown to the next day's refresh. The original Whisk has been folded into Flow.

Compared to the Veo API on Google AI Studio/Vertex, which requires payment or draws on the $300 new-customer cloud credit, the Flow web app is currently the best-value way for individuals to use Veo 3.1 for free.
