Google Veo 3.1 Fast
The fast, affordable version of Google's flagship video model — with native audio
Google Veo 3.1 Fast is the speed-optimized version of Google DeepMind's Veo 3.1 video model. It keeps the defining strengths of Veo 3.1 — native synchronized audio, cinematic realism, and strong prompt adherence — while generating significantly faster and at a much lower cost. On Keyo Studio, Veo 3.1 Fast is the go-to choice for high-volume video work: social content, ads, and rapid iteration where speed and value matter as much as quality.
What is Google Veo 3.1 Fast?
Veo 3.1 Fast is the efficiency-focused variant of Google's Veo 3.1 model, built for developers and creators producing video at scale. It delivers the same core capabilities as the full Veo 3.1 — native audio generation, image-to-video, character consistency, and cinematic quality — but is optimized for faster generation and a lower price per second. It's the practical default when you need many videos quickly rather than a single hero clip at maximum fidelity.
Native audio, built in
Like the full Veo 3.1, the Fast version generates synchronized audio in the same pass as the video — dialogue, sound effects, and ambient sound all aligned to the action on screen. You get talking characters with lip-sync, product videos with realistic sound, and social clips with baked-in audio, without any separate audio editing. This makes Veo 3.1 Fast uniquely capable among fast, affordable video models, most of which produce silent output.
Built for speed and volume
Veo 3.1 Fast generates videos noticeably faster than the full model, which makes a real difference when you're producing dozens of clips, testing variations, or running an automated content pipeline. Its lower cost per second means you can iterate freely — draft your concept quickly, refine the prompt, and only reach for the full Veo 3.1 when a specific clip needs maximum quality.
Social-ready formats
Veo 3.1 Fast supports both standard 16:9 landscape and native vertical 9:16 video, making it ready for TikTok, YouTube Shorts, and Instagram Reels out of the box. Combined with its speed and native audio, it's an ideal engine for social media automation, short-form ads, and high-frequency content production.
Best use cases
Veo 3.1 Fast is the right choice for high-volume, fast-turnaround video: social media content and Shorts/Reels, short-form ads and product clips, rapid prototyping and A/B testing of video concepts, automated content pipelines, and any workflow where you need many videos at a low cost per generation. When you need Veo-quality audio and visuals at scale, Fast delivers.
Pricing on Keyo Studio
On Keyo Studio, Google Veo 3.1 Fast costs 3 credits per second of generated video — significantly cheaper than the full Veo 3.1. This makes it the most cost-effective way to produce audio-enabled video on the platform, ideal for high-volume and iterative workflows. For maximum fidelity on hero clips, the full Google Veo 3.1 is available.
