As organizations increasingly incorporate Large Language Models (LLMs) into their offerings, managing multiple AI models can become complex, prompting the need for an LLM gateway. This gateway serves as a middleware that simplifies interactions by centralizing access, standardizing formats, balancing loads, and monitoring performance across different AI providers like OpenAI, Anthropic, Mistral, and Google. By acting as a reverse proxy, an LLM gateway helps overcome challenges such as integration overhead, inconsistent performance, cost management difficulties, and maintenance issues. Eden AI exemplifies this concept by offering a unified interface to various AI and LLM providers, enabling automatic routing, centralized monitoring, and secure API key management, thus allowing developers and companies to optimize performance and cost while maintaining control and visibility over their AI model usage.
