VDAR-Router: Adaptive LLMs Routing via Verbalized Query Difficulty Analysis Retrieval

За 30 секунд

Что произошло

VDAR-Router routes queries to different language models by analyzing query difficulty explicitly, then retrieving similar historical examples to guide model selection.

Почему это важно

Engineers deploying multiple LLMs need to balance performance and cost per query without retraining routing systems.

На что обратить внимание

Paper shows results on three datasets but doesn't specify which models were tested or whether the approach generalizes across different model families.
