Model denylist is a model-routing or gateway concept used to manage policy enforcement for AI requests. It describes a distinct decision, control, interface, or observation point between an application and one or more model providers.
Model routing and gatewaysModel fallback
Model fallback is the use of an alternate model or provider when the preferred route cannot handle a request or fails a defined condition. A fallback policy can respond to outages, rate limits, unsupported capabilities, timeouts, or application-level checks.
Model routing and gatewaysModel gateway
A model gateway is a service layer that gives applications a common interface to one or more model providers. Depending on its design, it can handle routing, authentication, retries, fallbacks, usage tracking, and request policies.
Model routing and gatewaysModel registry
Model registry is a model-routing or gateway concept used to manage operational visibility for AI requests. It describes a distinct decision, control, interface, or observation point between an application and one or more model providers.
Model routing and gatewaysModel routing
Model routing is the process of selecting which AI model handles a request or a step in a workflow. A routing policy can consider the task, required capabilities, expected quality, price, latency, and provider availability.
Model routing and gatewaysModel version pinning
Model version pinning is a model-routing or gateway concept used to manage operational visibility for AI requests. It describes a distinct decision, control, interface, or observation point between an application and one or more model providers.
