Why is Dutch more expensive than English?

Tokenizers split Dutch text into more pieces. In our measurement the same text costs 24 to 37% more tokens in Dutch than in English. See the [token index](/en/onderzoek/tokenindex/).

AI cost calculator: what does the API cost per month?

Q: Are these amounts exact?

It's an estimate. Every model counts tokens differently, and thinking tokens of reasoning models come on top. Use it to compare models and know your order of magnitude.

Compare what your AI application costs per month with GPT, Claude, Gemini and Grok. Prices kept up to date automatically.

In short

An application with 200 requests a day (400 words in, 150 out, in Dutch) costs from under a dollar a month on the smallest model to around $75 on the largest (November 2026 prices). Pick the smallest model that does your task well.

With API use you pay per token: what you put in and what the model writes back. The difference between models is huge, often a factor of 20 or more. Work it out before you choose.
