Why Agentic Inference Needs Prefix-Aware Routing Infrastructure
CoreWeave, Thursday, August 20th, 2026
CoreWeave explains why agentic workloads, which reuse most of each request's context, need prefix-aware caching and routing.
CoreWeave continues a series on how agentic applications create a fundamentally different infrastructure workload than traditional chat applications.
Each inference request in an agentic loop reuses most of the context from the previous one, which changes what the serving layer should optimize for. The post argues that prefix caching only pays off if the routing layer is aware of which cache holds which prefix.
Without prefix-aware routing, requests land on replicas that must recompute context the cluster has already processed. CoreWeave describes the infrastructure changes required to capture that reuse in production.
