Section 1
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.
