DeepSeek API is charged at off-peak rates all day on weekends.
DeepSeek's current API pricing rules show that peak billing only applies to the two UTC periods from Monday to Friday, while off-peak pricing applies for the rest of the time. Therefore, the off-peak pricing applies to the entire day on Saturdays and Sundays.
DeepSeek's current API pricing page shows that peak hours are only from 01:00 to 04:00 and 06:00 to 10:00 (UTC) Monday to Friday, with off-peak prices applicable during other times.Therefore, Saturdays and Sundays are typically off-peak times.
The official explanation states that the off-peak price is approximately half of the peak price, but the actual cost still depends on the model used and the types of input and output tokens. This adjustment does not mean that peak hours on weekdays have been cancelled.
