LLM Gateway provides a unified API interface for routing, managing, and analyzing requests across multiple Large Language Model (LLM) providers. It targets developers and organizations looking to streamline their LLM integrations, offering centralized API key management, usage tracking, and performance analytics for services like OpenAI, Anthropic, and Google Vertex AI.

How It Works

LLM Gateway acts as a middleware, abstracting the complexities of interacting with diverse LLM APIs. It presents a single, OpenAI-compatible API endpoint, simplifying application development and enabling easy switching between providers. The system routes requests based on configurable logic, tracks token usage and costs per provider, and collects performance metrics for analysis and optimization.
