Short answer
There is no current Gemini API price for the Veo 3.1 preview model IDs: Google says veo-3.1-generate-preview, veo-3.1-fast-generate-preview, and veo-3.1-lite-generate-preview were shut down on October 22, 2026. Google’s migration guidance points developers to Gemini Omni Flash or generally available models on Gemini Enterprise Agent Platform. Those alternatives are different routes or models; their prices should not be inferred from Veo 3.1 preview rates. (Google’s Gemini API video guide)
For the documented Veo 3.1 models on Agent Platform, Google lists Provisioned Throughput and Fixed quota as supported, and Pay-as-you-go as unsupported. The model documentation does not state a numeric price. So a current production budget for those models needs a quote or applicable pricing information for the exact model and arrangement—not the retired Gemini API rate. (Google Cloud model documentation)
Historical Gemini API price—not a current quote
At Veo 3.1’s 2025 Gemini API preview launch, Google said Veo 3.1 was the same price as Veo 3. Google’s published Veo 3 rate was $0.40 per second. That supports a historical standard-model comparison, but it is not a current Veo 3.1 API price after the preview shutdown. The cited pricing announcement does not establish the same historical rate for Veo 3.1 Fast, so this article does not assign Fast that rate. (Veo 3.1 launch announcement; Veo 3 pricing announcement)
For context only, applying the historical $0.40/second rate to an 8-second clip gives 8 × $0.40 = $3.20; 100 such clips would be $320. Google’s Veo documentation describes 8-second videos, but these calculations are historical arithmetic—not a forecast for a current model or production route. The cited rate announcement does not specify resolution or audio qualifications for that rate.
What production teams can verify
Google Cloud documentation lists these Agent Platform model IDs:
- Veo 3.1 Generate:
veo-3.1-generate-001— GA. - Veo 3.1 Fast Generate:
veo-3.1-fast-generate-001— GA. - Veo 3.1 Lite Generate:
veo-3.1-lite-generate-001— Preview.
For these documented models, the page lists 4-, 6-, or 8-second outputs. Generate supports output up to 4K; Fast and Lite list up to 1080p. These are documented model capabilities, not evidence of their prices or how duration and resolution affect billing. The page lists availability in the United States region us-central1; check the relevant project and route before relying on that availability. (Google Cloud model documentation)
API or platform pricing versus consumer subscriptions
Google AI subscriptions are a separate consumer product, not a production API rate. Google One’s page describes video-generation access in Gemini and Flow and displays Google AI Pro at $19.99/month or $199.99/year and Ultra at $99.99/month in its savings calculator. The captured plan details do not establish a Veo 3.1 API price or a model-specific production allowance, so those subscription amounts cannot be used to calculate API spend. (Google AI plans)
Bottom line
The old Gemini API preview IDs are shut down, and their historical rates are not current quotes. Google documents GA Veo 3.1 Generate and Fast models on Agent Platform, but the model page lists fixed quota and Provisioned Throughput—not pay-as-you-go—and does not state a dollar amount. For a current production forecast, confirm the price and terms for the exact Google route, model, and capacity arrangement you plan to use.
