Intelligent Multi-Model Routing Strategies

Implement smart routing to automatically select the best model based on query complexity, cost, and response time requirements.

The Case for Smart Routing

Different queries require different model capabilities. Simple FAQ responses can use fast, cheap models while complex analysis uses premium models.

Routing Logic Design

Implement a classification layer that routes queries based on complexity scores.

function routeQuery(query: string): string {
  const complexity = assessComplexity(query);
  if (complexity < 0.3) return "qwen-turbo";
  if (complexity < 0.6) return "qwen-plus";
  if (query.includes("analyze") || query.includes("compare")) return "qwen-max";
  return "deepseek-r1";
}

Cost-Benefit Analysis

Route 70% of queries to fast models, reserve premium models for 30% complex cases. This typically saves 50% on API costs.

Fallback Strategies

Always implement fallback routing when primary model is unavailable or rate-limited.
