LLM routing is a process that dynamically chooses the most suitable large language model (LLM) for a particular task, optimizing for cost, performance, and reliability. This approach allows queries to be directed to either lightweight, advanced, or multilingual models, ensuring efficiency and quality. As businesses increasingly rely on LLMs for applications like customer support and content generation, routing becomes essential to match the right model with the right task. Platforms like Eden AI simplify this by offering access to multiple LLM providers through a single API, enabling developers to test, compare, and integrate various models without the complexity of managing each individually. This strategy not only improves performance and reduces costs but also enhances the scalability and resilience of AI systems, making it easier for businesses to adapt to the evolving AI ecosystem.
