DeepSeek pricing — frequently asked questions
How much does DeepSeek API cost? ▼
DeepSeek API is billed on a peak/off-peak rate card, live since 16:00 UTC on 2026-08-16 (peak hours 01:00-04:00 and 06:00-10:00 UTC, Monday-Friday; all other hours, including weekends, are off-peak at exactly half the peak rate). DeepSeek-V4.1-Flash: $0.15/1M input cache-miss off-peak ($0.3 peak), $0.003/1M cache-hit off-peak ($0.006 peak), $0.6/1M output off-peak ($1.2 peak). DeepSeek-V4-Pro: $0.66/1M input cache-miss off-peak ($1.32 peak), $0.022/1M cache-hit off-peak ($0.044 peak), $1.98/1M output off-peak ($3.96 peak). Both models have a 1M-token context window and a 384K max output. The Flash rates were cut at the 2026-09-10 V4.1-Flash release; V4-Pro rates did not change. Concurrency is capped at 2500 requests on V4.1-Flash and 500 on V4-Pro.
How does DeepSeek compare to OpenAI GPT-4o on price? ▼
DeepSeek-V4.1-Flash off-peak cache-miss input is $0.15/1M vs GPT-4o's roughly $2.50/1M — about 17× cheaper — and output is $0.6 vs about $10.00. With cache hits, V4.1-Flash input drops to $0.003/1M off-peak, making reused-context input effectively negligible compared with US frontier models.
Is DeepSeek open source? ▼
Yes. DeepSeek model weights are released under the MIT license on Hugging Face. You can self-host DeepSeek on your own infrastructure or via third-party providers (Fireworks AI, Together AI, Amazon Bedrock) without using DeepSeek's API.
Which DeepSeek model names still work, and is V4-Pro being retired? ▼
The two current model names are deepseek-flash (DeepSeek-V4.1-Flash) and deepseek-v4-pro (DeepSeek-V4-Pro-0813). The deepseek-chat and deepseek-reasoner aliases were compatibility mappings onto the non-thinking and thinking modes of the V4-Flash generation and were deprecated on 2026-07-24. The names deepseek-v4-flash and deepseek-v4-flash-vision-exp are still accepted but those models were retired at the 2026-09-10 V4.1-Flash release, with requests served by DeepSeek-V4.1-Flash and billed at the Flash price — so a pinned legacy name keeps working while silently changing both the model and the rate. DeepSeek-V4-Pro is not being retired: a footnote scheduling its 2026-09-14 end-of-life was published on 2026-09-10 and withdrawn on 2026-09-11, and V4-Pro keeps its own rates with the billing method unchanged.
