model-routing
Model Routing Intelligence
Select the right Claude model for each task to optimize the cost/quality tradeoff.
Goal
Eliminate wasted spend by routing tasks to the cheapest model that produces acceptable quality, while ensuring complex tasks get the reasoning depth they need.
Decision Matrix
Task → Model mapping
| Task Type | Recommended Model | Reasoning |
|---|---|---|
| Architecture decisions | Opus 4.6 | Needs deep multi-step reasoning, hidden coupling detection |
| Complex debugging | Opus 4.6 | Root cause analysis requires holding many hypotheses |
| Security review | Opus 4.6 | Must not miss subtle vulnerabilities |
| Standard implementation | Sonnet 4.6 | Best balance of speed, quality, and cost for code generation |
| Code review | Sonnet 4.6 | Good pattern recognition at reasonable cost |
