How to build llm gateway?
A vendor-neutral, OpenAI-compatible LLM router that sends each request to the cheapest model meeting the quality needed, sold in Starter, Indie, Pro, Scale and Enterprise tiers plus metered usage. It is positioned on governance and audit rather than raw routing, because the market floor for routing is free.
A gateway sits between applications and model providers. Define a compatible request format, authenticate callers, enforce budgets and route to permitted providers. Add timeouts, retry limits, redacted logs and tests for provider failures before serving production traffic.
What to verify before buying
- Routing quality under the same evaluation set
- Provider fees plus gateway fees
- Budgets, log retention and access policy
- Fallback behavior, latency and audit exports
