Overview
The largest model is rarely the right default. Match capability, latency, and price to what the specific step of your product needs.
In this lesson you will:
- Weigh capability against latency and cost
- Route easy steps to a smaller, faster model
- Build an evaluation before committing to a choice
Pro Tip
Use caching and revalidation wisely to ensure your app stays fast and data remains fresh without unnecessary requests.
