Rate snapshot
Official reference: provider pricing docs
| Type | Rate | Per 1M tokens |
|---|---|---|
| Input | 0.00014 | $140.0000 |
| Output | 0.00028 | $280.0000 |
How token pricing works
Input tokens are the tokens you send to the model (system prompt, user message, context, retrieved docs, and tool payloads). They are billed at the input rate.
Output tokens are the tokens generated by the model in its response. They are billed at the output rate.
Output is often priced higher because generation is usually more compute-intensive than ingesting context. For this model, output is about 2.00x input pricing.
Real monthly cost examples
1,000 users/day, average 500 input + 300 output tokens
10,000 tasks/day with heavy reasoning (2,000 input + 900 output)
More workload patterns
30,000 input + 12,000 output tokens
120,000 input + 50,000 output tokens
80,000 input + 90,000 output tokens

Cost optimization tips
- Keep prompts compact and remove duplicated system instructions.
- Set max output tokens by task type to prevent response overflow.
- Cache repeated context and retrieval results where possible.
- Use a cheaper model for draft steps, then escalate only when needed.
- Track input/output ratio weekly and tune workflows accordingly.
- Teams commonly reduce API spend by around 20-30% after prompt trimming, caching, and output caps.
FAQ
What is Deepseek-chat cost per 1,000 tokens?
Divide the per-1M rates by 1,000. Input is about $0.1400 and output is about $0.2800 per 1,000 tokens.
Why is output usually more expensive?
Output token generation requires autoregressive decoding, which is more compute intensive than reading input context.
How can I reduce Deepseek-chat API cost?
Start with prompt compression, strict output limits, and caching for repeated contexts. Then route simple tasks to cheaper models.
