Model Routing

AI systems no longer depend on a single model. Different requests call for different tradeoffs across quality, speed, cost, context, privacy, and reliability. The routing layer determines how those tradeoffs are made. It also determines whether a multi-model system is genuinely better than a fixed integration.

ModelRouter.com is a free, independent reference for understanding that layer. It explains the underlying ideas, compares the infrastructure available today, and gives technical teams a clearer basis for deciding what belongs in their own systems.
