Records without a complete per-token API rate are listed separately. Missing API pricing is not a zero-cost estimate; licensing, hardware, cloud, storage, networking, and operations remain outside this calculator. See methodology for sources.

Frequently asked questions

What's the cheapest AI API?

In the current benchr snapshot, DeepSeek V4-Flash has the lowest listed hosted rate at $0.14 input and $0.28 output per million tokens. Records without a complete API price are listed separately; a missing API rate does not make licensing, hardware, cloud, or operations 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.
