These proxy services let you route standard OpenAI-formatted API requests to alternative providers and private infrastructure without rewriting your application code. They function as a control layer to handle automatic failover, response caching, cost tracking, and unified key management across multiple backends. When choosing a proxy, evaluate added latency overhead, reliable support for streaming responses, and whether you need an open-source self-hosted gateway or a managed cloud solution.

Smarter LLM routing. Lower inference costs.
