Unverified50% confidenceOpinionExact time
System One models generally refer to lightweight models with relatively few parameters, shorter reasoning chains, and extremely low response latency, in contrast to slow-thinking reasoning models such as o1 and DeepSeek-R1.

UnverifiedA Router Model refers to a dedicated model with smaller parameter count and lower latency responsible for classification and scheduling, reserving the compute of the heavy generative model for steps requiring creation or reasoning.73% similarUnverifiedSmaller models can handle fewer instructions than larger models, and non-reasoning models can handle fewer instructions than reasoning models.71% similarUnverifiedFirst-generation reasoning models often had a clear on/off switch, with the base model and reasoning model as two separate entities; nowadays it is more common for a single model to exhibit both behaviors, adjustable via reasoning intensity settings.70% similarUnverifiedThe core logic of a cascade routing strategy is 'never invoke a large model for what a small model can handle,' triggering a higher-cost model only when the small model's output confidence falls below a threshold.70% similarUnverified多模型动态切换的典型场景包括用轻量模型处理简单问答、重型模型处理复杂推理，以及主力模型不可用时自动故障转移69% similar
