Veo 3.1 is Google DeepMind's latest AI video generation model, capable of producing high-fidelity 1080p videos with synchronized, context-aware audio directly from text prompts or reference images. It introduces advanced creative controls, including the ability to use up to three reference images for character and style consistency, first and last frame control for seamless transitions, and scene extension for generating longer, continuous sequences. Veo 3.1's 3D latent diffusion architecture enables natural motion, temporal consistency, and precise audiovisual synchronization, making it suitable for cinematic storytelling, marketing, and content creation across platforms. The model is accessible via Google AI Studio, Gemini API, and Flow, and is available in paid preview as of October 2025.
