Veo 3.1

Preview

Google's current video-generation model, billed per second of generated video with audio: $0.40/s at 720p and 1080p, $0.60/s at 4K. Paid tier only, no free tier, so token price fields are N/A. Google states you are only charged if the video is generated successfully. No shutdown date announced. This is the recommended migration target for Veo 3 and Veo 2, alongside "the GA models available through the Gemini Enterprise Agent Platform".

Veo 3.1 by Google is tracked live in our LLM catalog. It is in preview.
