Frequently asked questions
What's the cheapest AI API?
It depends on the ratio of input to output in your workload. The calculator sorts the current published prices for the usage you enter; records without a complete API price are listed separately and never treated as free.
How much does Claude cost per month?
Depends on which tier. Enter your actual input, output, caching, and reasoning-token assumptions above for a model-by-model figure.
Does this include cached pricing?
Yes. Set the repeated-input percentage and the calculator applies each model's documented cached-input rate when available. Batch and cache discounts are not stacked.
Is the pricing up to date?
Prices come from the shared benchr model index, verified against official provider pricing pages and recorded in the changelog. Provider prices can change without notice.
