Frequently asked questions

How many chat models are listed?
There are 440 models matching this filter right now, pulled live from the OpenRouter public API and updated daily.
How often does pricing change?
AI model prices change frequently — sometimes weekly. Token Price Index rebuilds this page daily from the OpenRouter API so you always see current prices. Subscribe for price-drop email alerts.
How is the blended cost calculated?
Blended = (3 × input cost + output cost) / 4. This weights input 3:1 over output, reflecting a typical read-heavy workload. Sort by input or output $/M if your workload differs.
How can I get alerted when a chat model price drops?
Token Price Index Pro emails you the moment any model you follow gets cheaper — for $9/mo. No more manually checking provider pricing pages.
