OpenAI API Pricing & Model Reference
Explore upstream provider rates and model pricing for OpenAI models routed through Valstorm AI Platform, including batch execution and context caching rates.
Official Provider Documentation: OpenAI API Pricing | OpenAI Models Overview
Overview & Gateway Architecture
This reference document outlines the upstream provider base pricing for OpenAI models.
Like open model gateways and routing platforms (such as OpenRouter or OpenCode), the Valstorm AI Platform provides unified access to these upstream models alongside advanced enterprise capabilities:
- Intelligent Routing & Failover: Dynamic routing across models and providers with zero-downtime fallback.
- Enterprise Tool Execution: Sandboxed compute environments, web search grounding, vector retrieval (VFS), and database connectors.
- Context Caching & Optimization: Transparent prompt caching and token minimization pipelines.
- Multi-Tenant Security & Observability: Granular cost allocation, audit logs, and policy-driven rate limiting.
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.
