Frequently asked questions

How is the monthly cost calculated?
Requests per month × (input tokens × input price + output tokens × output price), using each model's list price per million tokens from OpenRouter's catalogue.
Why add reasoning tokens?
Reasoning models bill their thinking as output tokens even though it never appears in the answer. On our benchmark questions 58 models used reasoning tokens; Reka Flash 3 used the most, 4,030 per question on average. Your prompts may need more or fewer.
Which model was cheapest in your tests?
Granite 4.0 Micro by IBM had the lowest billed cost per benchmark question: $0.000051 on average, reasoning tokens included.
