Query Complexity Assessor

Software componentModel ServingModelsVariation point (abstract)arc:QueryComplexityAssessor

An abstract component that classifies an incoming query's complexity (e.g., simple, moderate, complex) before generation so that a router can select an appropriately sized model.

Responsibility. Classifies query complexity ahead of model selection.

Also known as: Complexity classification, estimate_query_complexity

Variants

VariantWhen to choose
Query Complexity ClassifierChoose when query phrasing varies widely and higher classification accuracy justifies the added latency and cost of a classifier model.
Rule-Based Complexity ClassifierChoose when query classes follow clear lexical patterns and zero added latency and cost matter more than robustness to phrasing variation.
