Gemini API provides programmatic access to Google's Veo 3.1 video-generation models through the generateContent interface, official Google GenAI SDKs, or REST requests. It is aimed at developers building cloud-based video workflows for small teams, mid-market organizations, and enterprises. Text-to-video and image-to-video generation are supported, with generated audio, portrait or landscape formats, and output from 720p through 4K depending on the selected model.

Veo uses usage-based pricing rather than monthly subscriptions. The published options include Veo 3.1 Lite at 720p or 1080p, Veo 3.1 Fast at 720p, 1080p, or 4K, and Veo 3.1 Standard at 720p or 1080p, or 4K. Every listed variant includes video generation with audio. The lowest listed rate is $0.05 per second for Veo 3.1 Lite at 720p, while prices vary by model and resolution. There is no free plan, so teams should estimate generation volume and resolution needs before choosing a tier.

The feature set is suited to production pipelines that need more control than a basic prompt-to-video endpoint. Developers can extend previously generated Veo clips, guide generation with first and last frames, and use up to three reference images for image-based direction. Durations can reach 8 seconds, and SDK support covers Python, JavaScript/TypeScript, Go, Java, and C#. Choose Gemini API when these controls, audio generation, and high-resolution output fit your application; consider another service if a free tier, monthly billing, or broader support channels are priorities.
