Why FastInfra

Built to win at scale

Stop juggling provider accounts, SDKs, and pricing spreadsheets. FastInfra gives your team one production API with the breadth of OpenRouter and the reliability your customers expect.

⚡

One integration, every model

Swap models with a single parameter. GPT, Claude, Llama, Gemini, DeepSeek — all through the same OpenAI-compatible endpoint your team already uses.

◎

Intelligent cost routing

Our routing layer automatically selects the lowest-cost upstream path per model, so you ship faster without leaving margin on the table.

◆
