Inside the Router Brain: How UnforgeAPI Routes Queries
Technical deep-dive into UnforgeAPI's intelligent query routing system. Learn how we decide between CHAT, CONTEXT, and RESEARCH paths.
The Router Brain
The Router Brain is the secret sauce behind UnforgeAPI's accuracy. It's a sophisticated query classification system that ensures every question gets routed to the optimal processing path.
Let's peek under the hood.
The Routing Challenge
When a user asks a question, you need to decide:
- Can this be answered from general knowledge? → CHAT
- Does this need proprietary/uploaded data? → CONTEXT
- Does this need fresh/real-time information? → RESEARCH
- Does this need a combination? → HYBRID
Getting this wrong is expensive:
- CHAT for a context query → hallucinations
- RESEARCH for a simple question → wasted API calls
- CONTEXT for a web query → stale information
How the Router Brain Works
Step 1: Query Classification
The Router Brain analyzes the query across multiple dimensions including type (factual, conversational, research, analytical), temporality, specificity, and complexity.
Step 2: Context Analysis
If context is provided, we analyze its relevance including keyword extraction, domain matching, and sufficiency checking.
Step 3: Routing Decision
Based on the analysis, we make a routing decision with path selection, confidence scoring, and fallback options.
Routing Examples
Example 1: Simple Greeting
Query: "Hello, how are you?" Decision: CHAT (confidence: 0.99)
Example 2: Company Policy Question
Query: "What's our vacation policy?" Context: Employee handbook Decision: CONTEXT (confidence: 0.97)
Example 3: Market Research
Query: "What are the latest AI trends in 2026?" Decision: RESEARCH (confidence: 0.94)
Example 4: Hybrid Query
Query: "How does our product compare to competitors?" Context: Product documentation Decision: CONTEXT + RESEARCH (confidence: 0.88)
Performance Metrics
The Router Brain adds minimal latency:
- Average routing time: <50ms
- Accuracy: 94% on our benchmark suite
- Fallback rate: <5% of queries
Why This Matters
Intelligent routing means:
- Faster responses (no unnecessary API calls)
- Better accuracy (right tool for the job)
- Lower costs (efficient resource usage)
- Predictable behavior (consistent routing)
The Router Brain is why UnforgeAPI "just works" for diverse query types without manual configuration.
