Veo-3.1

Veo 3.1 Fast is a video generation model developed by Google DeepMind that produces up to eight seconds of 1080p content at 24 frames per second. What sets this model apart is its emphasis on speed, making it well suited for creators who need rapid iteration and quick feedback during the video development process. The model generates native synchronized audio alongside video, including dialogue, ambient effects, and background sound. Advanced features include scene extension that supports chaining up to 20 clips into longer narratives, frames-to-video transitions between two images, vertical video generation for short-form content, and 4K upscaling. As part of the broader Veo 3.1 family, this Fast variant occupies a distinct role alongside a Quality version that prioritizes render fidelity over generation speed.

The Veo 3.1 family was introduced through the Gemini API in October 2025, with Veo 3.1 Fast designed as the speed-optimized counterpart to the Quality version. Available through both the Gemini API and Vertex AI, the model operates with a 1,000-token context window and training data through July 2025. While the generation time advantage of the Fast version over the Quality version may not be as dramatic as one might expect, the reduced render time still enables more iterative workflows for filmmakers and storytellers. The model supports text-to-video, image-to-video, and reference-to-video inputs, with commercial API access that makes it practical for production pipelines. For creators who need to experiment with ideas quickly and move through iterations efficiently, the Fast variant offers a practical balance between accessibility and capability.
