What DeepSeek costs: about as close to free as AI gets.
DeepSeek's whole pitch is price. Here is the honest breakdown — what is free, what the API actually costs, and the discounts that make a real workload almost free.
01Free where it counts
The chat app and website are free. The API is paid but priced far below the frontier, and new accounts usually get a free starter grant of tokens to build with before you spend anything.
02API pricing, in plain terms
You pay per token, split into input and output, with Flash dramatically cheaper than Pro. The numbers are small enough that for most personal and small-team use, a month of real work costs a few dollars — sometimes cents. Always check DeepSeek's current rate card before relying on a figure.
The discount that mattersContext caching. When your prompts share a repeated prefix (a system prompt, a long document), cached tokens are billed at a fraction of the normal price. For repetitive workloads this alone can cut the bill by most of it.
