Query Classification And Routing With Llm Based Decision Trees

via “request pre-classification and intent routing”

grāmatr — Intelligence middleware for AI agents. Pre-classifies every request, injects relevant memory and behavioral context, enforces data quality, and maintains session continuity across Claude, ChatGPT, Codex, Cursor, Gemini, and any MCP-compatible cl

Unique: Implements pre-inference classification as an MCP middleware layer that intercepts requests before they reach the LLM, enabling context injection and routing decisions at the protocol level rather than within prompt engineering or post-processing

vs others: Avoids forcing the LLM to perform its own routing logic, reducing token consumption and latency compared to in-prompt routing or post-hoc classification

via “routing pattern for dynamic task direction based on query classification”

Agentic-RAG explores advanced Retrieval-Augmented Generation systems enhanced with AI LLM agents.

Unique: Implements routing as an intelligent classification step that analyzes query characteristics to select specialized handlers, rather than using static rules or random assignment, enabling adaptive pipeline selection based on query semantics.

vs others: More efficient than single-pipeline systems by avoiding unnecessary processing steps, and more adaptive than rule-based routing by using LLM reasoning to classify queries based on semantic content.

via “tier-based model selection with cost-performance tradeoffs”

Adaptive LLM router with tier-based model selection and fallback support.

Unique: Implements explicit tier-based routing with fallback chains rather than simple load balancing, allowing developers to define semantic tiers (e.g., 'reasoning', 'classification', 'generation') and map them to specific models with cost/latency tradeoffs

vs others: More granular than round-robin load balancing because it considers request characteristics and model capabilities, not just availability

via “dynamic llm routing based on context”

MCP server: auto_llm_routing

Unique: Employs a decision tree-based routing mechanism that evaluates multiple context parameters for optimal LLM selection, unlike simpler static routing methods.

vs others: More adaptive than static routing solutions, enabling real-time adjustments based on user input and context.

via “query classification and routing with llm-based decision trees”


Unique: Uses the ChatGPT API itself as the classification engine rather than a separate ML model, with prompts designed to output machine-parseable category labels that enable downstream routing logic

vs others: Eliminates need to train and maintain separate intent classifiers; adapts to new categories by modifying prompts rather than retraining models, making it faster for prototyping and low-volume production systems

Build your AI Workforce

via “llm-powered customer inquiry classification and routing”

Unique: Bundles intent classification and routing as a pre-configured service without requiring developers to build custom classifiers or rule engines, leveraging the underlying LLM's zero-shot capabilities

vs others: Faster to deploy than building custom intent classifiers with training data, but less accurate and controllable than fine-tuned models or explicit rule-based routing systems

via “intelligent response routing based on confidence”

via “conditional branching and decision logic with llm-powered evaluation”

Unique: Supports both rule-based and LLM-evaluated conditions, allowing workflows to make intelligent decisions based on unstructured data (sentiment analysis, classification, reasoning) without requiring users to write conditional logic code or train custom models

vs others: More flexible than Zapier's conditional branching because it supports LLM-powered evaluation of unstructured data, though it introduces non-determinism and latency compared to deterministic rule-based branching
