Veo 3.1 Fast
Veo 3.1 speed — without sacrificing quality
Veo 3 Fast is Google DeepMind's speed-optimised variant of Veo 3, delivering the same native audio generation and cinematic video quality at faster turnaround and lower cost. It generates up to 8 seconds of synchronized audio-video content at 720p to 1080p, making it the practical choice for iterative content workflows, volume ad production, and campaigns where speed of output matters alongside quality. On Xarith, Veo 3 Fast sits alongside Veo 3 Standard in the model picker — use Fast for creative exploration and volume, switch to Standard for final hero creative.
Native audio at lower cost and faster speed
Veo 3 Fast retains the defining capability of the Veo 3 model family — native audio generation including dialogue, ambient sound, and sound effects — but delivers it at faster generation speed and reduced credit cost. For teams producing high volumes of social content with audio, Veo 3 Fast enables production throughput that Standard quality cannot match at the same budget.
Practical for A/B creative testing at scale
Performance marketers running structured creative tests across ad sets benefit most from Veo 3 Fast. Generate multiple prompt variants, audience cuts, and visual approaches quickly, identify which direction performs, then upscale the winning creative to Veo 3 Standard for final delivery. This two-stage workflow significantly reduces wasted creative budget.
Full social format support
Veo 3 Fast generates video in 16:9 for YouTube and display, plus other common aspect ratios for social platforms. The 8-second maximum duration covers most short-form ad formats and social content requirements.
