🛠️ LLM Gateway: Routing and Observability for LLMs

LLM Gateway is a TypeScript-based routing tool designed to connect your AI agents and applications with any large language model provider. In real-world AI application development, hardcoding a specific vendor's API often leads to technical debt. Developers need to handle interface discrepancies between models, track usage costs, and route traffic if a specific API goes down. This project addresses these infrastructure-level pain points. It acts as a unified routing layer while building in cost tracking and observability features. This is not a magic wand; it is a highly practical piece of middleware. If you are building a system that needs to interface with multiple LLMs (such as using OpenAI and Anthropic simultaneously) and requires granular management of API calls, a gateway tool like this is a standard architectural component.
