Prompt engineering boosts small language models for query routing

By PulseAugur Editorial · [1 sources] ·

A new arXiv paper explores the effectiveness of prompt engineering techniques for small language models (SLMs) in performing guarded query routing. The study evaluated 22 SLMs on the GQR-Bench dataset, focusing on their ability to route in-distribution queries and reject out-of-distribution queries. Results indicate that prompt optimization significantly improves the performance of compact models, with Mistral 7B and Qwen3.5 9B achieving notable gains. The research suggests that prompt optimization is a valuable initial step for SLMs in this task, though weaker models might still require weight-level adaptation. AI

IMPACT Demonstrates prompt engineering's effectiveness in enhancing SLM capabilities for specialized tasks like query routing.

    Influence of Prompt Engineering on Small Language Models for Guarded Query Routing

    arXiv:2607.24801v1 Announce Type: cross Abstract: We study the problem of guarded query routing, where we assume that a user query first meets a router that either determines the ideal endpoint for in-distribution queries or rejects out-of-distribution queries that are potentiall…
