What it does

LLM Gateway is a unified API that routes requests across 200+ models from 40+ providers such as OpenAI, Anthropic and Google. Developers can switch providers without code changes, track costs in real time and bring their own keys, with observability and guardrails built in.

How to use: To use LLM Gateway, users simply change their existing API endpoint to `https://api.llmgateway.io/v1` and use their LLM Gateway API key. It is compatible with the OpenAI API format, allowing for seamless migration and integration with existing code in various languages and frameworks like Python, TypeScript, Next.js, Java, Rust, Go, PHP, and Ruby. LLM Gateway then routes the request to the appropriate provider while tracking usage and performance.
