Peak and off-peak pricing
DeepSeek charges two prices for the same model. Off-peak rates are half the peak rates. Peak hours are 01:00 to 04:00 and 06:00 to 10:00 UTC, Monday to Friday, excluding Chinese public holidays. Every other hour, including weekends and Chinese public holidays in full, is off-peak. The calculator uses the peak price, so your real bill can be lower if your traffic runs off-peak.
A worked example
With 1,500 input and 400 output tokens per request and 1,000 requests a day, DeepSeek V4.1 Flash costs about $27.90 a month at peak prices and about $13.95 a month off-peak. DeepSeek V4 Pro costs about $106.92 at peak and $53.46 off-peak.

Both models have a 1,000,000-token context window and a maximum output of 384,000 tokens. DeepSeek also bills its Search and Fetch tools at $0.75 per 1,000 successful requests each.
