The rates above are per unit. Your bill is those rates times how hard your code leans on Mistral, plus everything around it. PrePrice scans your project, finds where you call Mistral, and computes your real cost per user and what to charge.
Find your real cost — freeBy output-token price, Mistral Small 4 is currently the cheapest Mistral model at $0.3 per 1M output tokens and $0.1 per 1M input. The cheapest model per token is not always the cheapest per finished task, since a weaker model can need more retries or longer prompts.
Mistral is pay-as-you-go and billed per token: you pay for input tokens (your prompt and context) and output tokens (the response) separately, priced per million tokens. There is no monthly base fee for the API itself.
The per-unit rate is only one of the four numbers that set your bill. The others are how much your app uses Mistral, how often, and across how many users. Long prompts, retries, multi-step agents, and uncached repeated context all multiply the rate. PrePrice models that usage from your code so the number is real, not a guess.
