arXiv:2605.17106v2 Announce Type: replace Abstract: Production LLM deployments increasingly maintain heterogeneous model pools spanning order-of-magnitude cost differences. Existing routers make binary strong-vs-weak decisions and couple learned parameters to specific model identities, requiring retraining whenever the catalog changes. We present HyDRA (Hybrid Dynamic Routing Architecture), a framework that predicts fine-grained, multi-dimensional capability requirements per query and matches them against configuration-defined model profiles via shortfall matching.

The proliferation of various LLM sizes and capabilities in production environments necessitates more efficient and dynamic routing solutions to manage costs and performance.
This architecture promises to significantly improve the efficiency and cost-effectiveness of deploying large language models by optimizing resource allocation based on query requirements.
LLM inference is no longer a monolithic process but a dynamically routed task, allowing for more granular control over computational resources and potentially lowering operational costs for AI deployments.
