Plain-English overview

What Veo 3.1 Fast actually is

Veo 3.1 Fast supports the same main creative inputs as the standard model—text, images, and video—but is tuned for quicker, less expensive iteration. It is a practical fit for social clips, ad variations, storyboards, and experiments where teams expect to generate several versions.

Google prices the Fast route by output resolution: 720p is the least expensive, 1080p costs slightly more, and 4K has a larger step up. Preview status and an eight-second requirement for high-resolution output still apply.
