VDAR-Router: Adaptive LLMs Routing via Verbalized Query Difficulty Analysis Retrieval
arXiv cs.AI · Published · 3 min read
In 30 seconds
- What happened
- VDAR-Router routes queries to different language models by analyzing query difficulty explicitly, then retrieving similar historical examples to guide model selection.
- Why it matters
- Engineers deploying multiple LLMs need to balance performance and cost per query without retraining routing systems.
- Watch out
- Paper shows results on three datasets but doesn't specify which models were tested or whether the approach generalizes across different model families.
