Veo 3.0 Fast Generate is Google's rapid-iteration video generation model, the fast tier of Veo 3.0, built for high-velocity prompt exploration, batch generation, and concept validation before committing to full-quality renders.
import { experimental_generateVideo as generateVideo } from 'ai';
const result = await generateVideo({ model: 'google/veo-3.0-fast-generate-001', prompt: 'A serene mountain lake at sunrise.'});Veo 3.0 Fast Generate is the fast-tier variant of Google's Veo 3.0 video generation family. It launched simultaneously with the other Veo variants on AI Gateway as the model to use when iteration speed matters more than maximum fidelity.
Fast mode reduces per-generation latency. For a team building a video generation tool, that means running a dozen scene descriptions through the model in the time a single quality-tier generation might take, and finding which framing, style, or narrative direction works before investing in a full-quality pass. Despite the speed focus, the fast tier carries Veo 3.0's core capabilities. Enable native audio generation (sound effects, ambient audio, and synchronized dialogue) with generateAudio: true in providerOptions.vertex. Image-to-video is also supported, letting you animate a starting frame with natural motion.
For batch workflows like generating multiple versions of the same scene, testing audio-on versus audio-off, or comparing aspect ratios, the fast tier's lower latency compounds across a batch and significantly shortens the feedback loop.
