An LLM API gateway (also called an AI gateway or proxy layer) is an intermediate service located between applications and large-model providers that exposes a standardized interface externally (commonly the OpenAI /chat/completions specification) and internally is responsible for translating and forwarding requests to different vendors' endpoints while uniformly handling authentication, billing, rate limiting, and logging.
