VerifiedLLM routing is an inference optimization strategy that dynamically selects models based on task complexity, cost budget, and response speed requirements; open-source frameworks such as RouteLLM and LiteLLM are already exploring this direction.78% similarUnverifiedLLM路由（模型级联）是一种基于任务复杂度动态选择模型的成本优化策略，Martin Fowler将其类比为微服务架构中的API网关模式78% similarUnverifiedAn LLM gateway is responsible for routing model calls, centrally managing credentials, adding logging, imposing rate limits, and handling overhead tracking.78% similarUnverifiedThe underlying mechanism of multi-model collaboration typically relies on a Model Router or LLM gateway component to dynamically distribute requests based on task type, token cost, and latency requirements.77% similarUnverifiedDistilling patterns from massive historical runs into a lightweight model to serve as an external plug-in for LLM decision-making is a more cost-controllable, flexible, and easily iterable bypass enhancement approach compared to retraining or fine-tuning the main large model.73% similar
