The rates above are per unit. Your bill is those rates times how hard your code leans on DeepSeek, plus everything around it. PrePrice scans your project, finds where you call DeepSeek, and computes your real cost per user and what to charge.
Find your real cost — freeBy output-token price, deepseek-v4-flash is currently the cheapest DeepSeek model at $0.28 per 1M output tokens and $0.14 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.
DeepSeek 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 DeepSeek, 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.
