Use cases
Routing requests between cheap and expensive modelsCombining outputs from multiple models for higher qualityCoding assistants (e.g. GitHub Copilot)Agentic systems with multiple specialized models
How it works
A router analyzes the request and, based on rules, a classifier or metadata, sends it to the appropriate model. In advanced variants multiple models generate candidates in parallel, and an aggregation mechanism (voting, ranking, a judge model) selects or merges the best result.
Problem solved
No single model is best at everything or cost-optimal; a layer is needed to combine the strengths of multiple models.
Strengths & limitations
Strengths
✓Better quality than a single model
✓Cost and latency optimization
✓Flexibility and resilience (fallback)
Limitations
✗Increased system complexity
✗Latency overhead with parallel execution
✗Difficulty in evaluating and debugging the routing layer
