These routing gateways dynamically direct user prompts across multiple foundation models based on live performance, cost thresholds, and target capabilities. They solve the headache of single-provider downtime and runaway API bills by automatically triggering fallbacks and dispatching simpler queries to faster, cheaper endpoints.
