Routing prompts to the cheapest sufficient model saves serious money.
11 min · Reviewed 2026
The premise
Sending every prompt to the top model wastes money. A router classifies tasks and sends each to the cheapest model that handles it.
What AI does well here
Classify task type from a brief description.
Send simple tasks to small/cheap models.
Escalate complex tasks to larger models.
Track per-model spend and quality.
What AI cannot do
Predict perfectly which model will succeed.
Substitute for actual quality measurement.
Practice this safely
Use a small project example from your own work. The useful move is to compare the AI's draft against your goal, sources, and constraints before you trust it.
Ask AI to explain model-router in plain language, then underline anything that sounds uncertain or too broad.
Give it one detail from "AI Model Routers: Pick the Right Model Per Task" and ask for two possible next steps plus one reason each step might be wrong.
Check cost-optimization against a trusted source, teacher, adult, expert, or original document before you use it.
