What DeepSeek V3 costs
| Rate | Per 1M tokens | Per 1K tokens | What it covers |
|---|---|---|---|
| Input | $0.27 | $0.00027 | Every token you send: prompt, history, documents. |
| Output | $1.1 | $0.0011 | Every token the model generates, including hidden reasoning tokens. |
| Cached input | $0.07 | $0.00007 | Input served from the provider’s prompt cache. |
What that means in practice
The same three workloads are costed on every model page, so these numbers are directly comparable across the catalog. No prompt caching and no batch discount is assumed — the figures are what you pay before you optimize anything.
Support chatbot
2,500 six-turn conversations a day
$986 / month
$0.013 per conversation · $11,834 a year
An 800-token system prompt, 400-token questions and 900-token answers, over six turns — each turn re-sending everything before it.
Document summarizer
1,000 single-shot summaries a day
$125 / month
$0.0042 per conversation · $1,503 a year
One 12,000-token document in, an 800-token summary out, no conversation history. The case where input dominates the bill.
Coding agent
200 twelve-turn sessions a day
$713 / month
$0.119 per conversation · $8,558 a year
A 3,000-token system prompt, 1,500-token instructions and 2,500-token responses over twelve turns. Long sessions are where the quadratic cost of re-sent history stops being theoretical.
