DeepSeek is free to use through its website and mobile app, with no cost for chat, writing help, or file uploads.

For developers, DeepSeek offers an API that is billed by usage, based on the number of tokens processed.

• DeepSeek-V4-Flash: Costs $0.14 per 1 million input tokens, $0.0028 per 1 million tokens on a cache hit, and $0.28 per 1 million output tokens.

• DeepSeek-V4-Pro: Costs $0.435 per 1 million input tokens, $0.003625 per 1 million tokens on a cache hit, and $0.87 per 1 million output tokens.

Charges are calculated by multiplying the number of tokens used by the price, and fees are taken automatically from your account balance. You only pay for what you actually use, so there is no fixed monthly fee for the API.
