Veo 3.1 – an AI video generation model developed by Google

What is Veo 3.1？

Veo 3.1 is Google’s latest AI video generation model, representing a major upgrade from Veo 3. It introduces enhanced audio support, stronger narrative control, and more realistic texture rendering. With native audio generation and refined editing capabilities, Veo 3.1 enables users to complete video creation directly during the generation process—without the need for post-production. The model supports multiple input types, including text prompts, images, and video clips, and can generate high-quality 720p or 1080p videos. Veo 3.1 aims to simplify the creative production workflow and empower creators across various domains such as advertising and virtual content production. The model is available through Gemini API, Vertex AI, Flow, and Gemini.
