Starting from August 23, DeepSeek has adjusted its API billing rules by eliminating the weekend peak-off-peak price differential. Charges will be applied at off-peak rates throughout Saturdays and Sundays, while weekdays will continue to follow peak and off-peak time-based billing. Previously, the V4-Flash and V4-Pro APIs employed peak-off-peak pricing, with peak prices reaching up to twice those of off-peak times. This adjustment aims to provide users with greater flexibility in scheduling their operations and to balance the platform's computational load. Charges incurred prior to this change will still be settled according to the old rules.
