Orchestration & Routing
Definition
Routing tasks to models or agents based on semantic features of the input.
Explanation
Semantic routing uses embeddings or classifiers to analyze user intent and content, then selects the optimal LLM, agent, or workflow. This improves performance, reduces cost, and ensures proper model specialization. Unlike rule-based routing, semantic routing handles natural, ambiguous, or complex input gracefully.
Technical Architecture
User Input → Embedding → Semantic Router → Selected Model/Agent → Output
Core Component
Embedding index, classifier, routing policies, fallback models
Use Cases
Enterprise copilots, multi-agent ecosystems, LLM orchestration
Pitfalls
Routing errors reduce accuracy; latency if routing is too complex
LLM Keywords
Semantic Routing, LLM Router, Model Router
