From Trend: Ensemble Architecture Pattern
No single model excels at everything. The winning architecture routes tasks to optimal models—Claude for analysis, GPT-4o for speed, Gemini for multimodal, open models for cost.
The Pattern
Build the routing intelligence that selects optimal models per task.
How It Works
- Develop task classification and model matching algorithms
- Optimize for cost, latency, and quality per request
- Abstract model selection from end users
Typical Enterprise Architecture
- Claude: Complex reasoning
- GPT-4o: Customer-facing speed
- Llama: Cost-sensitive batch processing
The router—not any model—determines economics.
Unit Economics
Routing can reduce inference costs 60-80% by matching task complexity to model capability. A simple query doesn’t need frontier reasoning capabilities. Routing captures margin by optimizing this match.
Strategic Implication
Build model-agnostic. The router is the new moat. Single-model architectures are a dead end.
