Overview & Gateway Architecture
This reference document outlines the upstream provider base pricing for Google's Gemini family of models.
Like model routers and API gateways (such as OpenRouter or OpenCode), the Valstorm AI Platform provides unified access to Google Gemini models with full enterprise infrastructure:
- Intelligent Routing & Caching: Multi-model routing, prompt context caching, and 1M+ token window management.
- Multimodal Intelligence: Unified endpoints for text, high-resolution vision, native audio streaming, video processing, and PDF/document tokens.
- Integrated Tool Execution: Sandboxed code execution, Google Search grounding, Maps lookup, and file search integrations.
- Enterprise Controls: Unified auth, organization-level quotas, and strict multi-tenant data governance.
Note: Base provider rates shown below represent upstream pass-through pricing in USD per 1 Million (1M) tokens unless specified otherwise. Platform usage includes upstream consumption plus applicable platform value-add markup.
1. Gemini 3 Series (Current Generation)
All prices are in USD per 1M tokens for the Paid Tier.
