How DeepSeek API pricing works
DeepSeek bills per token: an input price for everything you send and a higher output price for what the model generates, both quoted per million tokens. To estimate a real bill, multiply by your monthly request volume — the cost calculator does this across every model at once.
Before committing to volume, always confirm the current numbers on the official DeepSeek pricing page — the list prices here are verified periodically but the market moves fast.
