What is Confidence-Based Routing?
Definition
Confidence-based routing is an AI system design pattern where queries are directed to different processing paths based on the system's confidence in its ability to answer them. High-confidence queries may be answered directly from cached or indexed knowledge, while low-confidence queries are escalated to more thorough (and resource-intensive) reasoning pipelines.
Why It Matters
Engram uses confidence-based routing to balance speed and thoroughness. Simple lookups are answered instantly, while complex questions are routed through deeper analysis — always with transparency about confidence levels.
