What Is the Veo 3.1 API? A Complete Guide to Google DeepMind’s Video Model

What Is the Veo 3.1 API?

Google DeepMind’s Veo 3.1 API is a powerful video generation model designed for realistic physics, lighting, and surface details. It enables text-to-video workflows where generated visuals closely mimic real-world movement and texture.

Key Capabilities

High realism: Exceptional physical accuracy for motion and object interaction.
Advanced shading: Detailed light and shadow rendering.
Surface detailing: Enhanced textures and fine-grain visual fidelity.
Audio pairing: Automatic soundtracks to match video context.
Adaptive frame features: Intelligent first-frame selection and content-appropriate transitions.

Veo 3.1 vs Sora-2

Strengths of Veo 3.1:
- Best-in-class physical realism.
- Superior lighting and surface detail handling.
Weaknesses vs Sora-2:
- Costs up to 2× more.
- Slightly lower prompt adherence for certain scenarios.
