Section 1
The premise
Routing platforms cut spend by sending easy queries to cheap models — but hidden costs (latency, vendor risk) need care.
What AI does well here
- Route by predicted task complexity to cost-appropriate models.
- Provide unified API across providers.
- Track cost savings vs. always-frontier baseline.
What AI cannot do
- Predict quality without observing your specific workload.
- Replace your own eval suite.
