I build AI products that ship.

The Problem

Using GPT-4 for every request was burning through API costs. But downgrading everything to a cheaper model hurt quality. I needed smart routing.

My Approach

• 1.Classify task complexity (simple, medium, complex)
• 2.Route to appropriate model tier
• 3.Implement semantic caching for repeated queries

The Code

// Triple-tier model routing
function selectModel(task: Task): Model {
  const complexity = analyzeComplexity(task);

  if (complexity === 'simple') {
    return 'gpt-3.5-turbo';  // $0.002/1K
  }
  if (complexity === 'medium') {
    return 'gpt-4-turbo';    // $0.01/1K
  }
  return 'gpt-4';            // $0.03/1K
}

// Result: 92.6% cost reduction
// Quality maintained at 98.2%
