A Multi-Layer Query Guardrail Framework for Stateless LLM Deployments

Key Points

The aim is to enhance the reliability and efficiency of stateless LLM deployments through a structured query management system.
Developed a three-layer query control pipeline
Implemented a word-level filter
Used fastText and GloVe for semantic intent classification
Incorporated an LLM guardrail prompt for domain enforcement
Reduced API costs associated with LLM usage
Prevention of domain drift in language outputs
Improved overall system reliability in production environments

Abstract

This paper proposes a three-layer query control pipeline for stateless LLM deployments. The system combines a word-level filter, semantic intent classifier using fastText and GloVe, and an LLM guardrail prompt to enforce domain constraints. The approach reduces API cost, prevents domain drift, and improves system reliability in production environments.
