How DeepSeek-V4 Pro pricing works
DeepSeek-V4 Pro is billed per token: a lower input price of $0.435 per million tokens for everything you send, and a higher output price of $0.870 per million for everything the model generates. To turn that into a real DeepSeek-V4 Pro bill, multiply by your monthly request volume and average prompt/response length — the calculator above does exactly that.
Prompt caching is the biggest lever on your DeepSeek-V4 Pro cost: cached input tokens bill at just $0.0036 per million — about 99% cheaper. If you reuse a long system prompt or context across calls, caching can dramatically cut the input portion of your bill.
