# Gateway

> Build a centralized LLM gateway with Opik to streamline access to multiple LLM providers using a consistent API format.

An LLM gateway is a proxy server that forwards requests to an LLM API and returns the response. This is useful for when you want to centralize the access to LLM providers or when you want to be able to query multiple LLM providers from a single endpoint using a consistent request and response format.

## Gateway Integrations

Opik supports several LLM gateway solutions to help you centralize and manage your LLM provider access:
