LLM Query Router & Gateway

Architecting high-performance gateways that scrub input prompts, evaluate safety rules, and direct queries to optimized private model containers.

Architecture Overview

Deploying a single massive model for all business tasks results in elevated latency and computation costs. This LLM routing architecture acts as a traffic control plane, directing basic requests to fast sub-7B models while reserving larger parameter models for high-value reasoning. All evaluation occurs locally behind the firewalls.

Gateway Flow Stages

1. Prompts Intake & Security Validation

API requests enter the gateway proxy. A lightweight security filter evaluates the text, scrubbing personal identifiers, database keys, and proprietary codes.

2. Intent Classification

A rapid, local routing classifier parses the user query, identifying the required skill type (e.g. database query, formatting task, or complex compliance audit).

3. Model Selection & Dispatch

Basic queries are routed to smaller parameter local instances, optimizing GPU memory. Complex legal or geological queries are dispatched to multi-GPU clusters running larger models.

4. Output Safety Filter

Model answers are checked for compliance and accuracy against corporate rules before returning to the requesting client app.
