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.
As of August 13, 2026, the flagship deepseek-v4-pro endpoint — now serving the general-availability V4 Pro 0813 build that left preview on August 12 — lists these rates per million tokens:
V4 Pro list rates, per million tokens
- Input, cache miss: $0.435
- Input, cache hit: $0.003625
- Output: $0.87
Read those first two rows again: a cache hit costs about 1/120th of a cache miss. That is not a rounding difference, it is the whole game — which is why the section below is the one that actually decides your bill. The endpoint carries a 1M-token context window and a 384K-token maximum output.
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.
A price rise is on the record. DeepSeek's own rate card carries a notice that the company plans a significant increase in overall API pricing, with specifics to come by official notice. The rates above are what is published today, not a promise for the quarter — if you are building a budget on "DeepSeek is nearly free," build in headroom.

Does DeepSeek have a free tier?
Yes — the chat app and website are free, and the API typically includes a free starter grant of tokens.
Why is DeepSeek so cheap?
Efficient training and serving plus open weights let it undercut frontier pricing dramatically, which is what pressured competitors to lower their prices.
What is context caching?
A discount where repeated prompt prefixes (like a system prompt or a long document) are billed at a fraction of the normal token price — a big saving on repetitive workloads.
Is DeepSeek about to get more expensive?
Possibly. DeepSeek's own pricing page carries a notice that the company plans a significant increase in overall API pricing, with specifics to be confirmed by official notice. Until that lands, the published V4 Pro rates hold — but do not build a long-term budget assuming they will.
