How to optimize your spend

Finding the right model isn't just about the cheapest price-per-token. It's about "Effective Cost" — the total amount you pay to get a successful, high-quality result without needing multiple retries.

1. Cascading Model Strategy

Use a "small" model (like GPT-4o-mini or Haiku) for intent classification and simple routing. Only trigger the "large" model (Sonnet or Pro) when the task requires high reasoning.

2. Context Window Caching

Models like Claude 3.5 Sonnet offer prompt caching. If you reuse large system prompts or documents, caching can reduce your input costs by up to 90%.
