DeepSeek / Pricing
Understand what
DeepSeek API usage costs.
Separate the service you are buying from the model you are calling. These rates apply to the official developer API.
Chat-app pricing and API pricing are separate.
A token rate is not a subscription price for the official chat app. Check the official chat’s current account and plan information for its terms. A third-party host may also set its own prices.
Official API rates
Prices are in US dollars per one million tokens. Cached input, uncached input and generated output are billed at different rates.
| Model | Period | Cached input | Uncached input | Output |
|---|---|---|---|---|
| DeepSeek-V4.1-Flash | Off-peak | $0.003 | $0.15 | $0.60 |
| DeepSeek-V4.1-Flash | Peak | $0.006 | $0.30 | $1.20 |
| DeepSeek-V4-Pro-0813 | Off-peak | $0.022 | $0.66 | $1.98 |
| DeepSeek-V4-Pro-0813 | Peak | $0.044 | $1.32 | $3.96 |
Peak hours: Monday–Friday, 01:00–04:00 and 06:00–10:00 UTC. All other hours use off-peak rates.
The three parts of a token bill
01
Uncached input
Input that does not receive the provider’s cache-hit treatment. Your prompt and any conversation history included in the request contribute to input usage.
02
Cached input
Input eligible for the provider’s cache-hit rate. Do not assume every repeated prompt receives this rate; use the usage reported by the API.
03
Output
Tokens generated by the model. The bill depends on actual usage, the selected model and the applicable pricing period.
Estimate from actual usage.
For one pricing period, add each token category separately: cached-input tokens × cached-input rate, plus uncached-input tokens × uncached-input rate, plus output tokens × output rate. Divide the total by 1,000,000 because the listed rates are per million tokens.
For a monthly estimate, sample the tasks you expect people to run. Include the conversation history sent on follow-up requests, retries and any separately billed services. Review the provider’s current rates before adding credit.
